THE WARRIORS HAD HALTED UPON THE PATH WITHIN A FEW PACES OF THE FUGITIVES.


"We are bewildered," said one of them, "for some minutes ago a comrade reached us from the village, telling us that the other white prisoner had escaped, and had flown beyond the river. But how can that be, for we know that the zareba away in the desert is still surrounded, and there can have been no one to help the slave? And yet this man of whom I speak reports that there is evidence that at least a hundred crossed to the village on the farther side of the water, and then went their way again in a southerly direction. The orders are that we at once return, and make ready to pursue them."

"It is strange, indeed," chimed in a second. "As I stood at my post, thinking that nothing would occur to disturb the silence, I heard the report of a gun, and realized that the enemy was at work again. But I, too, cannot understand how there can be men abroad to harm us. Perhaps this is a mistake, and we shall do well to pause ere we draw in our lines, for it may fall out that this is only a ruse, and that the escaping prisoner is even now making his way in this direction."

"Hark!" cried a third at this moment. "I think the sound of a galloping horseman just now fell upon my ears. Stand still, brothers, and be silent while I signal to him. If it is not answered, we shall know that it is this infidel for whom we are waiting; and then——"

"Ah!"

Each one of the group gave vent to a guttural exclamation, which denoted the delight he would feel should his long watch prove successful in the end. Then all waited in silence, while the man who had last spoken did as he had suggested. It was weird to hear that low cooing noise vibrating upon the midnight air, and still more wonderful to note how accurately the cry of the owl was reproduced. Twice in succession was it sent out from the throat of the warrior, and then as they listened, hoping against hope that it would not be repeated from the stranger, the distant splash and clatter of hoofs striking upon the path and upon the springy turf at its side ceased suddenly, and a wailing cry came shrilly in response. Then once more the galloping hoofs could be heard and very soon a horseman dashed up to the party. Not till he was almost upon them, and ran the danger of riding them down, did he attempt to pull in his steed, for the Somali loves a brilliant equestrian, and rather than save pain and distress to the animal he rides, prefers to pull upon its mouth until the bit cuts into the flesh, and the poor beast is dragged upon its quarters.

"The order is reversed," cried the horseman, flinging his reins upon the neck of his mount and springing to the ground. "Our father, the Mullah, has with his great wisdom discovered a ruse, cunningly planned by the enemy. He finds that they have not fled beyond the river, but in this direction. He commands, therefore, that you set a careful watch, and bring the captives to him by dawn. If you are not successful, he himself will come out in the daylight and lead you. Those are his orders."

"And we will see that they are carried out at once," cried one of the group. "Listen, comrades. It is useless for us to wait here expecting these infidels, for they would never dare to come by the path. It is in the bush that we shall find them, and in all probability nearer to the village than we are now. Let us separate from here, therefore, and ride away to right and left."

The remainder of the natives hastily expressed their approval, and as time was of much importance, and they could not afford to indulge in delay, they at once parted with one another, and melted into the darkness as silently as they had come.

"Things look brighter for us," said John Margetson, in a whisper, hastily interpreting all that had passed. "These men declare that it is useless watching the path along which we came, and that is a fact which will serve our purpose admirably, for, if I remember rightly, the ravine has its opening close beside a turn in the road, and it, too, should escape observation. Lead on, Jim, and let us make a run for this hiding-place."

Springing to their feet, the trio emerged from the thorn-bushes, and taking the beaten track again, pressed on at a rapid pace, for, now that it was certain that their ruse had been discovered, it was of great importance to them to find a lair at an early moment. Otherwise, however carefully they hid themselves in the undergrowth, the search-parties would be certain to discover them at the first streak of daylight, and then their fate would be settled. Having traversed a few hundred yards, Jim, who was again leading the party, broke into a walk, and began to study carefully the left-hand edge of the road. Then he suddenly turned away on to the grass, and striding forward, halted, as the pale glimmer of water caught his eye.

"The well which lies at the entrance to the ravine," he explained in a whisper. "We pass it by and then sweep round to the right until we are out of sight of the path. Then I shall give the signal arranged upon between Ali and myself. Follow closely, and be ready to come to a stop at any moment."

He pressed forward, and gradually inclining towards his right till he judged that the path would no longer be visible had it been daytime, he stopped and gave vent to a low cough. Again he repeated the signal, and waited in silence for the answer. So long an interval elapsed that at last it appeared as if Ali Kumar must have been forced to leave his post, or as if he had fallen into the hands of the enemy. But just as Jim was about to repeat the signal for the third time, there was a cough close at hand, and someone seemed to start from the darkness and stand beside him.

"I am here, master, and rejoice at your return," was said in a voice which was undoubtedly that of Ali Kumar. "Speak! Are you unhurt, and sound in wind and limb? And is one of the two who accompany you the Mullah's white slave, the father for whose rescue you yearned?"

"I am strong and well, and my father is here, Ali. In addition, I have brought with me a second prisoner, the one whom you saw when you went to the village, and whom you took to be the colonel. But we have no time to chatter here, for the Mullah's followers are hotly in chase. It is a relief to find that you are still in the ravine, for it shows that it has escaped the search of the enemy. Take us farther into it, and show us a spot where we can defend ourselves, for you may be sure that these Somali people will go over the road again, and hunt each corner of the land as if they were dogs."

"We have a grand hiding-place, master," was the answer, "though I cannot say that the ravine will escape a further search. However, there is that within these walls of earth which will aid us, should we be discovered, and from which we should be able to drive away every follower that this tyrant possesses. But, come, follow closely, and do not hesitate to hold out your hands on either side, for the path is rugged and dangerous, and in the dark it may well happen that one of you might strike his head against a rock, or tumble and break a limb."

"Right! Push on like a good fellow! We'll look to ourselves."

Ali at once turned about, and pushed on into the ravine at a swift pace, which taxed the efforts of those who came after him. Striking to the right, he soon came to a part which was shrouded in even denser darkness, and then began to mount slightly, following a track which seemed to cut its way along the side of the tiny valley.

"Have a care, my masters," he whispered suddenly, turning round when he had traversed some forty yards of this path. "At this point our road bends abruptly to the left, and comes to an end at the entrance to an ancient mine, which your servant discovered by the merest chance. It is faced outside with hewn blocks of stone, and from that point runs back for some little way, widening as it does so. Then it divides, and numerous galleries pass away into the hill, but how far I dare not say, for I would not explore one of them to save my life. The opening is close at hand, and when we reach it, I warn you to bend low, for the archway is of no great height and would injure men of your stature."

This news was a surprise indeed, and in other circumstances would have almost taken their breath away. But the excitement of the past few hours, the numerous incidents which had been crowded into their lives whilst in the Mullah's village, had left but little room for wonder. With scarcely a murmur, therefore, at the strange tidings which they had just heard, they demanded to be led on again, and followed the native, with only one thought in their minds—the longing to find themselves in some hiding-place, some haven in which they could take refuge, and, if necessary, defend themselves against attack.

Pressing swiftly forward, Ali Kumar swung to the left, and ere long came to a halt for the second time.

"We are here, my masters," he said. "Take heed of my words."

Once more he advanced into the inky darkness, Jim and his two companions following without hesitation. It was soon evident to all that they had entered some underground chamber, for each felt a rough archway of hewn stones above his head, while his surroundings suddenly became even denser and less visible. Then the pungent smell of smouldering logs fell upon their nostrils, and in the distance they saw the faint glimmer of a fire. At the same time they noticed that camels were in the place, for the irregular outlines of two of these animals could be seen upon the floor away on the right, while, closer at hand, was a large pile of newly cut grass with which to feed them.

Striking across the large entrance-hall of the mine, Ali strode to the fire and seized a brand, then he raised it above his head, and bade his followers look about them.

"I have seen places like this elsewhere," he remarked, "and a hunter whom I accompanied from the coast informed me that they were the work of an ancient people who lived and throve hundreds of years ago. They discovered by their wisdom that gold lay hid among the hills and rocks, and straightway set their slaves and captives to labour in the mines. But these races of which my master spoke must have died out, and become almost forgotten, though the tribes who live in Africa still have legends which tell of their existence."

"He speaks the truth," said Colonel Hubbard, going to the fire and helping himself to a piece of flaring timber, with which the better to inspect his surroundings. "I, too, have seen such works as these elsewhere in the continent of Africa, and so greatly has my curiosity and interest been aroused that I have explored some of the mines, and have gone to the trouble of hunting up literature upon the subject. It is currently reported, on the strength of an old legend, that Queen Sheba herself set sail from a point on the northern coast of Africa, not far removed from Berbera, and made her historic journey to the court of Solomon. No doubt her wealth was derived from mines like these, and it is even possible that as soon as this country is opened up, others may become rich from the same source, for an expert, who accompanied me when searching the old workings of which I have spoken, assured me that many of them were still capable of producing gold. But I must not forget that we are fugitives, and that even now the Mullah's followers are hunting for us. The question arises as to whether we should remain here or push on for Jim's zareba. I shall not venture to offer my opinion until I have heard him speak, for this is his adventure, and it is my wish that he should carry it through to the end."

"And mine, too, colonel!" exclaimed John Margetson.

"What you say is fair and right, for our young friend has shown most admirable coolness and a ready wit. We must remember that it was he who thought of entering the country on your behalf, and that he has already been the leader of a small following. To deprive him of that post at this moment would be mean indeed, and would cast a slur upon him. For myself, I have the utmost faith in his decision."

At the words Jim flushed red with pleasure, for there was no doubt that they were said in earnest.

"It is more than kind of you both," he began, after a short pause, during which he looked sharply about him. "As you have left this matter to me, I will settle it, if possible, but I ask you to correct me should you consider my decision unwise or unreasonable. When I consider that the surrounding country is overrun by enemies, and that to venture from this curious place would mean capture, I say at once that we should be fools even to dream of quitting such a spot. Why, look at it! That low and narrow arch is just the position which four desperate men should be able to defend so long as food and drink lasted, and it is my advice that we at once make plans to keep watch at the entrance, in case of discovery. Our future actions absolutely depend upon the existence of sufficient supplies."

"Then you may call it certain that we have flesh and water to last us for a month," interposed Ali Kumar. "Look there, master! There we have a store of food, while yonder, in the corner of this great chamber, is a pool of clear spring water, into which a stream drains from the hillside continually, while the overflow disappears through a crevice in the floor."

Turning suddenly upon his heel, the native shikari pointed to the two sleeping camels, and then away to one side of the entrance-hall. Looking in that direction, and by the aid of the torches, Jim and his comrades at once caught the reflection from the surface of a large pool of water, while a moment later, as they stood there listening, the gentle splash of a falling stream came to their ears.

"Good!" said Jim, in tones of pleasure. "I reckon that, if we were to slay one of the beasts, we could cut the flesh into strips, as the Boers and Red Indians do, and cure it by placing it outside in the sun, or by drying it over a smoky fire. Yes, in my opinion, that absolutely settles the question. Our game is to stick to this place through thick and thin, and resist all attacks; and meanwhile two of our number can easily be spared to explore some of these workings which I see lead from this hall. Indeed, the more I think of it, the more certain am I that Ali's find will prove to be the very thing for us; for, supposing the Mullah and his men rush the entrance, we can still retire into one of the tunnels, and make things hot for them."

"I fully agree with you, my boy," said Colonel Hubbard heartily. "So long as powder and shot last, we four men—for I count you equal to ourselves in strength and pluck—should be able to keep the enemy out. Then, if things get too hot for us, we shall retire, with food, and water too, if we can carry it, into the old workings and defy the Mullah's army. Indeed I doubt whether one of them would have the courage to pursue us underground, for these natives are superstitious fellows, and fear all kinds of imaginary things. Had it not been for that, they or their ancestors would have quickly investigated these mines, and would have turned them to account. But for generations they have been little better than savages, and have been pleased with an existence which has been spent partly in agricultural pursuits, and partly in raids upon their neighbours. And now, how are we to defend the position?"

"I've an idea," cried John Margetson, suddenly snatching the torch from the colonel's hand and advancing to the entrance. "But, first of all, I should like to know from Ali the condition of affairs outside, for I confess that, though I have been for three years a slave to the Mullah, I have never been in this ravine. Indeed, amongst the Somalis, it is scarcely known, and I doubt whether a single one of them has ventured into it; for it is considered to be haunted, and that is quite sufficient to keep all inquisitive people away. But answer my question, Ali, like a good fellow."

"The valley is a narrow one, and, indeed, when looked into from the hills above, is more like a deep pit with steeply sloping sides. A well stands at the opening, which is but a few yards in breadth. But, farther in, the walls give back quickly, and then slowly approach again, till a sharp angle is formed, in which this mine is situated. In the old days, of which my master's father has spoken, a paved road led down the centre of the ravine, and ascended easily to this entrance, and by that, no doubt, the slaves were wont to come to their work. But the store of water in this chamber has cut its way through the floor, and, issuing upon this stone, has, in course of time, cut a deep and wide furrow across it to its bed beyond, from which it flows to the well beside the village path. For that reason, my masters, I led you by a track which ascended the slope of the hill."

"Then my plan should be of service to us," said John Margetson, who had closely followed Ali's explanation. "It seems to me that when the morning comes, and we have daylight to help us, we shall have an uninterrupted view of the whole ravine from this low-arched entrance of the mine, and shall be able to cover every foot of it with our rifles. But we must remember that these Somalis possess many firearms, and if they happen to discover us, and can get rid of their fears of the supernatural, they will lie upon the slopes about us and pour in their fire with certain aim, for the range will be a close one. Only then should we learn that to lie at the entrance would be impossible, for it would cost us our lives. Do you follow me, my friends?"

"Quite easily!" exclaimed the colonel. "Had you had the training of a soldier, you could not have seen the danger more clearly. I am waiting impatiently to hear how you propose to get over the difficulty, which, there is no doubt, is a very real one."

"Then listen, colonel. My idea is a very simple one, and had I not thought of it, you or your son would quickly have done so. Since life to us would be impossible, even though we were to lie flat upon the floor, my suggestion is that we set to work with what implements we have and dig a trench of sufficient depth just within the opening to allow us to obtain shelter. The earth which we remove can be thrown up in front, so that the hole need not be more than three feet in depth."

"It seems a splendid proposal," cried Jim, who had been listening attentively. "I notice that the floor here is also paved with slabs of stone, but the earth beneath is soft, and quite loose, as you will see for yourself if you look at this large patch here, where the covering has been removed. That being the case, the sword which I took from the sentry who was watching over father's prison should be sufficient to thoroughly turn it up, and the remainder of the work can be finished with our hands. If we were to set to at it now, the job would be finished by daylight, and then all would be in readiness in case of attack."

For some little time the fugitives stood thoughtfully considering the question, and then, taking care that the torches should not be brought too close to the entrance, they went there in a body and closely inspected the ground. Thrusting the long native sword into a crevice between two of the paving-slabs, the colonel rapidly levered one of them up, and lifted it out of its place. Then he put the point of the weapon upon the bare earth, and pressed firmly upon the handle, with the result that the blade sank into it easily until the hilt stopped its farther descent. A gentle tug released it, and, when it was held up to the light, they saw that it was not even stained.

"We're in luck!" cried the colonel. "The soil beneath is composed of pure sand, and can be removed with the greatest ease. Look here!"

Dropping upon his knees, he thrust his hands into the opening which he had made and drew them out filled with shining particles.

"That explains the reason for these slabs, and for the paved road outside," he said; "for if they were not here, movement would have become most difficult, and the slaves, as they trudged to and fro with their bags of quartz or of gold-bearing sand, would have had a weary time indeed. Let us get to work at once, for the sooner the task is finished, the better."

Placing their weapons upon the pavement close at hand, the party at once began to tear up the square slabs of stone. They found that, when one had been removed, the rest gave little trouble, and ere many minutes had passed they had cleared a long and narrow track across the opening of the mine. Then they began to shovel out handfuls of sand, and did not desist from their labour until a deep trench had been dug. And now, at Jim's suggestion, the slabs were relaid at the bottom, while a few were used as a narrow coping on the summit of the bank which they had thrown up in front of the trench. Through this four narrow embrasures were left to accommodate the muzzles of the guns, and were cut so deeply that the weapons could be fired whilst the heads of the defenders remained completely under cover.

Two hours later the arched opening became more visible, and soon the rays of the sun were pouring down upon the land.

"I vote for a meal," sang out the colonel cheerily. "We may as well have it now, while we are undisturbed, for we may not have the opportunity later, and besides, you remember the old tale that men fight better and more bravely when they have had all their wants satisfied."

Nothing loth, for their exertions during the night had sharpened their appetites, the remainder of the party hastily agreed, and turned with questioning eyes towards Ali Kumar. The shikari was by no means disconcerted, and instantly crossing the entrance of the mine to where the camels lay, he returned with one of the saddle-bags, in which was stored the greater portion of the food which he and Jim had thoughtfully brought from the zareba.

The fugitives had barely done justice to the meal when a low cry from Ali alarmed them, and, looking out through their embrasures, they caught sight of a group of dusky figures standing at the mouth of the ravine. That their eyes were fixed upon the old mine-workings was evident, and soon there was little doubt that the sight had attracted their attention. They remained close together, talking and waving their arms, and then, to the consternation of the defenders, they were seen to be searching for marks upon the ground. That success was likely to attend their efforts was without question, and indeed but a little time had elapsed before one of them gave vent to a shout, and called to his comrades to join him. An instant later the party separated, scrambling like so many monkeys up the steep slopes of the tiny valley, and, when they arrived at the top, each man instantly began to wave his arms aloft, and shout the news of the discovery to all who were within hearing.


CHAPTER XIX

A STRATEGIC RETREAT

There was no doubt that the hiding-place of the fugitives was now discovered, and that they must prepare to defend their position and their lives; for, knowing the character of the Mullah, they could not hope to escape from attack. Sooner or later, and as quickly as they could overcome their fears of the spot, the fierce followers would advance into the ravine and pour their bullets into the entrance to the mine. Indeed, in view of the fanatical hatred in which they held the infidels, it was more than probable that they would gather together in a body and throw themselves with the utmost ferocity upon the fugitives. But we must leave the little party for a few moments and once more fly to the coast and see how the preparations for invasion were progressing.

The reader will recollect how a force had collected at Berbera, and, following in the wake of Jim's expedition, had marched across the lowlands and reached the highlands by the very pass in which the latter had so severely defeated the tribesmen. The rendezvous of the British troops had been Bohotle, which had already been strongly reinforced, and filled with supplies calculated to last at least six months. As a strategic base, this was the very best that the country offered in these parts, for it was practically on the fringe of the Hoad, and guarded the wells at which the last store of water could be obtained. From that point onwards a march of at least six days must be contemplated, across a waterless desert, before the invading force could reach the Mudug pasture lands in which the Mullah had made his home. From the farther fringe of the desert, two days at most would be occupied in marching upon the Mullah's stronghold, and after that much depended upon circumstances. If the enemy stood and faced the troops boldly, as he had boasted he would, there was every hope that short work would be made of his army, and that the same fate would befall him as had happened to the Khalifa in the Soudan. On the other hand, he or his men might suddenly become fearful of this small band marching against him, and might fly into the interior. If that were to happen, much would depend upon whether the force which had already set out from Obbia, and that which had left the Abyssinian frontier, were able to cut off his retreat and compel him to come to action. For the moment, no one could tell how the affair would turn out, but the troops at Bohotle were in the finest spirits, and confident of success. Making little of the privations before them, therefore, they welcomed the notes of the bugle which sounded the reveillé on the morning selected for the advance, and fell into their ranks with faces which showed their enthusiasm. Had their leader but known the precarious position of Jim's zareba, and the fact that our hero himself, together with three friends, was at that moment awaiting the attack of the Mullah's whole force, he would have pushed on with even greater haste, for his men were fit and ready for any exertions. But though he was aware of the marching of a small expedition into the interior, and knew what its object was, he had received no tidings of the fortune or misfortune which had befallen it, and therefore, in accordance with the arrangements which he had so carefully drawn out, he did not venture to begin his march across the Hoad before the date which had been agreed upon. Now, however, the time for action had arrived, and with a feeling of enthusiasm which was not less than that displayed by his officers and men, he gave the order to march, and, having seen the advance guard leave the camp, sat there upon his pony in the glare of the morning sun, watching critically as each battalion and each portion of the transport corps passed him. Then waving a farewell to the unlucky ones who were to remain behind to garrison Bohotle, and who gave him a ringing cheer in return, he set his beast into a canter, and in due time took his post at the head of his men.

The expedition which had been gathering at Obbia and elsewhere on the Abyssinian frontier had also set out on the date agreed upon, and were even then pushing forward as rapidly as possible in the hope of coming to close quarters with the Mullah.

With this knowledge, let us return to the fugitives in the mine. Seated upon the edge of their trench, with their faces glued to the embrasures which perforated the low bank of sand in front of them, our hero and his comrades had kept their eyes intently fixed upon the Somali scouts, and had seen, with a thrill of excitement, that these men had already guessed their whereabouts.

"They are signalling to the others," said Jim with an effort to keep his voice steady. "I suppose we must soon expect to have a large force attacking us."

"That just depends upon how long it takes for the news to spread," remarked the colonel, his calmness quite unruffled by the sudden excitement. "Unless those fellows who are waving and shouting from the top of the hill can be seen a long distance away, it seems to me that it may be many hours before the others are informed of our discovery, and consequently no serious attack will be made upon us for the present."

"The deduction is a good one, but, unfortunately, the facts are not precise," interposed John Margetson, in tones which showed that the turn events had taken had not been without its effect upon him. "I am quite an old resident in this country, you must remember, and I shall tell you one of the many things which I have learnt. It is the power these natives have of transmitting news to one another across long distances. Those beggars whom you see up there, apparently waving their arms in a reckless manner, are, nevertheless, fully alert and quite aware of what they are doing. Just as we in the Navy use semaphores to convey our news to distant vessels, so do these Somali fellows roughly send their messages to one another by means of their arms. Look at that chap up there! He is standing alone on the summit of the hill, so that his figure is against the sky-line, while his comrades are taking care to keep well away from him, so that those who are looking on at a distance shall not be confused. You may take it from me that there is another native, a mile or more away, upon a second hill, and still another elsewhere. By their means the order to concentrate at this ravine will flash across the country, and the swift ponies which these Somalis possess will quickly bring them to the spot."

"Then we must make up our minds for an early fight," said Jim calmly; "and, so far as I can see, we are fully prepared, and have no need to do more than sit where we are, awaiting developments. We've fed, and feel contented. For my part, having so recently had a brush with the native tribesmen, I feel confident that our chances are good, and that, so long as our ammunition lasts, we can defy these people."

"That's just the way to take it, my boy," sang out Colonel Hubbard cheerily. "Recklessness in a soldier is, as a general rule, inexcusable, for he should take good care to count the odds. But I freely admit that the forlorn hope has on many occasions gained us a victory, though it is not advisable. But there is nothing like going into an engagement with full belief in yourself, for then you have every determination to be successful. As to the power these beggars have of signalling, it is an interesting piece of information, and one of which I was quite unaware. But the news does not absolutely astound me, for I have met with a similar thing elsewhere. For instance, look at the Kaffirs, who inhabit a land in which we have been so recently fighting. They have some extraordinary means of conveying tidings to one another. Indeed, the result of large engagements, and even of small skirmishes, was known by these people a hundred and more miles away long before our telegraphists had been able to send it over the wires. But we must not occupy our attention with these matters at the present moment, for there is no doubt that we are in for a struggle. I therefore propose that we inspect arms at once."

Acting on this suggestion, all the available weapons were brought forward and their merits discussed. Then the ammunition was carefully counted out and put in a convenient spot. It was found that the party owned two modern rifles which Jim and Ali Kumar had brought with them from the zareba, and for which a large store of cartridges was available. Then there was the muzzle-loading gun which John Margetson had thoughtfully carried away from the store-hut, together with a quantity of powder and a bag of slugs, while in his belt he still retained the revolver which Jim had handed to him. As for the colonel, his son had presented him with the second revolver, so that each one of the party was fully armed, while there was one firearm over in case of accidents. In addition, they possessed the long double-handled native sword, in case of attack at close quarters.

"It seems to me that we are excellently provided," remarked Jim, when the inspection was completed. "If we are careful not to throw away a shot, our ammunition should last for a considerable time. The bag of slugs will be the first to require replenishing, and in that case I should imagine a few chips from one of these stone slabs would answer the purpose just as well. But—I say—look at those fellows!"

The group of Somali warriors, who had been standing upon the hill-top signalling to their friends, had become greatly enlarged, and within a very short space of time some two hundred men were stationed there, staring down into the ravine, and looking with suspicion at the entrance to the mine. But as yet not one had dared to enter the haunted valley, though they did not hesitate to crowd together at the opening, as if in the act of doing so.

An hour later their numbers had increased to quite double, while a movement amongst them showed that some leader was expected. That it should prove to be the Mullah himself was not wonderful, for he had promised to help his followers to capture the runaways. His charger was soon seen upon the sky-line, while a figure stood with the reins hooked over his arm, listening to the words of his scouts.

"Now something will happen," said the colonel calmly. "That rogue will find some means by which to quiet his followers' fears, though I doubt whether he will dare to lead them in person. See! He is haranguing them, and to show that there is no danger to be apprehended, he is descending into the valley alone. By Jove! With those rifles we could knock him over to a certainty. But fair play's a jewel, and for myself, I confess that I don't care to fire at a man unless I know that he is about to do the same to me; it's too much like murder to sight a weapon for a native clambering down the slope of a hill and pull the trigger on him. All the same, the prejudice is a silly one, for were we to drop him in his tracks, the chances are that his followers would decamp, and in that case the expeditions which are about to march into the country would find that they had little work to do. Look at the ruffian!"

Clambering down the steep slope of the hill, it was not long before the Mullah had gained the centre of the ravine, where he stood for some few moments, observing the paved road which traversed it. Then he turned to his followers, and called loudly to them to come and join him.

"Slide down, and have no fear!" he shouted in reassuring tones. "The story that this place is haunted is an old woman's tale, made only to frighten the children. But you are brave men, and there are your enemies, the infidel dogs, who have had the insolence to come hither. By Allah! I swear to you that no harm shall befall you, and I call upon you once more to join me, and then to rush with all your fury upon the mine."

For a short space of time it was clear that his followers hesitated, but on the Mullah's repeating his assurances, they began to descend one by one, and then came sliding and running down in a body. Very soon they were collected together in the centre of the ravine, and at a shout from their leader they advanced towards the mine.

"Now, Jim," whispered the colonel, "we're in your hands, for you are the senior officer at present."

"Then hold your fire till I give the word," was the calm response, "and then you can blaze into them for all you are worth."

Standing on the stone pavement at the bottom of their trench, each of the defenders carefully adjusted his weapon, Jim and Ali taking care to throw open the catch of their magazines, while John Margetson placed the spare revolver close at hand, so that, when his gun was discharged, he would still have something to fall back upon. Then, in absolute silence, and without allowing any portion of their figures to be observed, they waited with fast-beating hearts for the attack of the enemy. It came even sooner than they had expected, for, spurred on by the Mullah's words of encouragement, and by their own fanatical hatred of the infidel, the mass of Somali warriors came bounding towards the mine, those on the outer edge crushing towards the centre in their desire to take a part in the battle. As a result, they became closely jammed together, and arrived at the arched entrance in this formation.

"Fire!" cried Jim, when they were only a few yards away.

Instantly the guns of the defenders rang out and poured a perfect hail of missiles into the enemy. At such a close range it was impossible to miss one's aim, and therefore the losses sustained by the Somalis were very great. Indeed, so unexpected was the volley, and so disconcerted were they at the fall of their comrades, that all at once stopped their mad rush at the mine, and stood there aghast at the slaughter, and hesitating how to act. The breathing-space thus afforded was taken full advantage of by Jim and his friends, for, instantly reloading, they sent a second volley into the attackers. Its effect was excellent, for, finding that more of their fellow-warriors were falling, and that as yet not one of them had caught sight of the enemy, the Somalis gave vent to a howl of dismay, and retreated at the top of their speed. Nor did they pause until they had clambered from the ravine to the top of the slope outside.

"That will make them think twice about the matter," said the colonel, with a chuckle. "And just look at their leader! He took particular care not to join in the attack, and was the very first to scramble away to a safe distance. However, a humbug, such as he is, will soon stir up the tribesmen again by reminding them that we are few in numbers, and that the score against us is a heavy one. Then, no doubt, we can expect a second attack, and, if I know their wily commander at all, he will adopt different tactics."

How true the prophecy of the colonel was destined to be was soon found out, for, after retiring out of sight for a short period, the Somalis again appeared on the surrounding heights. Then they dropped silently into the ravine, and, lying down in the long grass at the foot of the hills, began to pour a hot fire into the mine. Soon, indeed, the air was alive with their slugs and bullets, which came whistling in through the opening. But, thanks to the trench which John Margetson had suggested, the defenders ran no danger of being hit, but sat down at the bottom, placidly listening to the uproar. For half an hour the fusillade continued without cessation, and, indeed, at the end of that time, became even louder and fiercer.

"It sounds as though they had been strongly reinforced," remarked Jim, whose coolness had never for a moment deserted him. "I'll just take a look through one of our peep-holes and see what is happening, for it would never do to make the sudden discovery that they were rushing upon us again."

Accordingly, taking every precaution not to expose himself to the bullets, he cautiously raised an eye to one of the embrasures, and closely inspected the ravine. He found that what he had thought had just occurred, for even then scores of men were climbing over the hill-tops, to slide at once into the valley beneath. Down below a large force of Somalis was gathered, and these, it was easy to perceive, were filled with excitement, and eager for the attack. They were shouting to one another, and brandishing their weapons.

"We can expect a second rush in a few moments," said Jim, sinking into the trench again; "there are scores of the enemy, and it seems to me that we shall be wise if we at once take steps to arrange for a retreat. I cannot think that our four weapons will be sufficient to keep them out. No doubt we shall kill a number of them, but all are in such desperate earnest that those who survive will come on, in spite of their losses, and once they get to close quarters with us, we shall be done for. I suggest, therefore, that a couple of us go and investigate those passages, while the others keep watch here. Then, as soon as the advance begins, a shout will bring us together again."

"A good soldier should always arrange for an orderly retirement," remarked the colonel thoughtfully, "for it is not always wise to burn your boats behind you, or destroy your bridges. I must confess that in this case we shall be wise to do as my son suggests, for it will help us to fight the harder if we possess the knowledge that retreat is possible. At the same time, I am quite sure that we are men enough to stand to our guns to the very last, and, in spite of a means of retirement, to stick to our position so long as it is tenable."

"Hear, hear!" sang out John Margetson, who, as the danger increased, seemed to become more cheerful. "Both of you have made most excellent proposals, and, as they do not need seconding, I shall show my approval by at once volunteering to form one of the exploring party."

"Then Jim had better go with you, my friend. I will remain here with Ali, and when you hear a shout, come back to us as fast as you can."

The question having thus been settled, and it being evident that there was no time for delay, the two who had been selected for the enterprise left their weapons on the edge of the sandbank, and, crawling from the trench, crept to the left, where they were quickly out of the range of the bullets. Then they sprang to their feet and ran to the fire, which still smouldered, and, snatching a couple of the largest brands, stepped towards the many openings which ran from the entrance-hall into the workings of the mine.

"Which one?" asked John Margetson, holding his torch aloft. "All are of exactly the same size and appearance, so that it is difficult to make a choice."

"Then I vote for the central arch," cried Jim. "Come along."

Darting across the intervening space, which was swept by a cloud of bullets, they plunged into the dark opening, and then, with firebrands held well in front of them, advanced at as rapid a pace as possible. They found themselves in a tunnel, which was of sufficient height to allow them to stand easily. A glance on either side showed them that the walls were composed of bare rock, or of sandstone, while the roof was supported at short intervals by buttresses of stone on either hand, and by a girder of the same material stretched from summit to summit. Like the hall and the ravine outside, the floor was paved with square blocks, but in parts these had caved in, and the recesses were filled with dark pools of water. Elsewhere falls of the roof and of the sides had taken place, and obstructed the passage, but in no place did it close it completely. Indeed, in view of the fact that hundreds of years had probably passed since the workings had been constructed, their condition was marvellous, and reflected the greatest credit upon those who had slaved at their construction.

But Jim and his comrade had little time for observing all these points, for they were conscious that their pressing needs would admit of no delay. Avoiding, therefore, the depressions and crevices in the floor, and clambering over the mounds formed by fallen rocks and débris from the roof above, they pushed on at a pace which brought them many a bruise from projecting obstacles. But they never seemed to heed them, and, scrambling along, had quickly traversed some two hundred yards of the tunnel. At this point they came to a crossway, where a passage ran to right and left.

"I should think that our best plan will be to take the direct road," said Jim, coming to a halt. "However, we will just see where these two tunnels lead to. You take that on the right, John, while I go to the left. If after walking some twenty yards you find nothing extraordinary, return at once, and meet me here."

Without discussing the question further, they separated at once. When they met again in the space of a couple of minutes, each reported that the crossway opened into a parallel tunnel a few yards away, and into still another farther on.

"Then it looks as though the openings from the entrance-hall ran on into the hill, diverging slightly, and connected at this point by a cross-cut. Evidently our path lies right ahead."

"You've hit the right nail this time, without a doubt," answered John Margetson. "Forward is the word."

When they had advanced some two or three hundred yards farther, the explorers suddenly came to a spot where the workings converged, and here they found a chamber which was larger even than that at the entrance. From it again there were many exits, into which they dared not venture. However, they had already gone far enough to learn that, should the enemy prove too strong for them, they had a way of retreat which would enable them to elude pursuit for some time.

"I doubt even whether these Somali beggars would dare to follow us as far as this," said John Margetson; "and if they do, I think we can guarantee that they shall be thoroughly scared. But I am firmly of belief that by pushing on we should come to an exit on the other side of this enormous hill, for the air here is perfectly pure and good, which is wonderful, when you come to consider the age of these workings. It looks, in fact, as though there was a perfect system of ventilation, a precaution which the ancients were too wise to neglect. Hullo! That was a shout."

At that moment a loud cry reached their ears, the sound, indeed, seeming to be collected together and enlarged by the solid walls of the mine. There was no doubt that it came from the two defenders who were watching the Mullah's followers, and at once Jim and his companion took to their heels, and raced back at their fastest pace. Arrived at the entrance-hall, they flung their brands into the fire and darted across the floor to the trench, in which they at once took their places.

"You have returned in the nick of time," remarked the colonel, in unruffled tones, "for those fellows outside are on the point of attacking. You can hear for yourself that the firing has ceased. But tell me, what luck have you had?"

"Splendid, father. We've explored the central tunnel, and find that it runs on for a considerable distance before coming to a meeting-place in the centre of the hill, from which a second series of workings emerge. If we have to fly, there will be plenty of room in which to play hide-and-seek, and always a chance of turning upon our followers and punishing them."

"Then we put the command in your hands as before, my boy, and leave it to you to give the word to retire. But, remember, all of you, that ammunition is valuable, and that you must not forget to carry every cartridge away with you."

His last words were interrupted by a perfect babel of sounds which came from the ravine, and each of the defenders at once sprang to his position, and, looking through the embrasure, saw that the enemy had begun to advance. This time they had taken the precaution to observe some order, and collecting together into a long, tongue-like band, came rushing up the central road towards the entrance of the mine. As before, Jim waited calmly until they were within easy range, and then gave the word to fire. Immediately a volley flashed from the sandbank, and a number of the natives fell. Then the defenders emptied their magazines into the closely packed ranks, and set to work with all haste to load again. For the second time they repeated the process, causing great loss to the enemy. But, in spite of that fact, the latter still rushed forward with marvellous pluck, and with loud shouts. Leaping over the bodies of the fallen, shrieking with pain, and tumbling headlong to the ground in their haste, they struggled fiercely to get at the infidels. Arriving at the deep cutting which the stream had made through the pathway, the foremost leapt it successfully; but those behind were not able to see it till right upon its edge, and, pushed by those who followed them, fell into the abyss with wild shrieks. Soon some thirty of them had met with this fate, and the gulley was full to overflowing. But their comrades never paused, never even hesitated, but, roused to fury by the loss of their friends, and by the stinging hail of bullets which still swept amongst them, came on with fierce determination, and in such huge numbers that it quickly became clear that there was no stopping them.

"Give them a last volley!" shouted Jim, raising his voice above the din. "Now, all together, and afterwards let us bolt."

Waiting till all were prepared, the four defenders rapidly emptied their magazines into the enemy, until the barrels of their weapons were so hot that they blistered their fingers. Then snatching up the piles of ammunition which they had placed close at hand, they scrambled from the trench, and, running swiftly across the entrance-hall, dived into the central tunnel, for all the world like rabbits taking to their burrows.

"Halt!" cried Jim sharply, at this moment. "Without a torch we shall be lost. Wait here till I get one."

Returning, he ran to the fire, and quickly secured four flaming brands, then he rejoined his comrades, noticing as he was about to enter the workings that the cries of the attackers had suddenly ceased, and that they had all come to a halt outside the mine, as if too fearful to enter it. But scarcely had the fugitives traversed more than a hundred yards of the tunnel, when loud shouts and cries again rent the air, and being magnified by the enclosing walls, came echoing and reverberating into the working. Indeed, the natives had at last overcome their superstitious terrors, and, rendered desperate by the baffling tactics of the infidels, had flowed into the entrance-hall till it was packed with humanity. Then a second pause ensued, for the passages which led on into the hill looked dark and forbidding. However, a leader was forthcoming, who, imitating Jim's example, snatched at one of the fiery brands, and, having peered into each one of the tunnels in succession, finally waved to his comrades to divide and search all of them.

Meanwhile the fugitives had sped on without a pause, and very soon arrived at the large chamber, which seemed to be the heart of the workings. And here they halted to listen for sounds of the pursuers.

"It is perfectly clear," said the colonel, seating himself to regain his breath, "that these fellows have overcome their fears, and are in hot chase. It occurs to me at the same time that the movement we have made was a most excellent one, for the very fact that there are so many channels leading into the hill will cause the Somalis to divide up into parties. Then in the darkness they will lose one another, and in that way will fall easy victims to our rifles, if they happen to come up with us. My advice is that we sit here for a little while, and then take matters more easily, for we shall require all our powers later. Perhaps we shall find an exit, and in that case we shall be obliged to travel fast to the zareba."

Accordingly the party crossed to the other side of the chamber, and entered the tunnel which stood opposite to that from which they had just emerged. Then lowering their torches, so that the flames could not be easily observed, they sat down to await events. Presently they became aware that some, at least, of the natives were close at hand, and prepared to push on, or repel the pursuers, as circumstances should dictate. But there was no need for interference on their part, for as they peered into the depths of the chamber, the glowing end of a firebrand suddenly appeared, the feeble light enabling them to perceive that five men only accompanied the bearer. They were on the point of levelling their rifles at these intruders when there was a shout from one of the side tunnels, and before the onlookers could realize what was about to happen, a second party of Somalis rushed into the open space, and mistaking the first for the flying infidels, threw themselves with spear and sword upon them.

"I almost expected a catastrophe of that sort," whispered the colonel; "and it is very probable that it may occur elsewhere, for our pursuers are too angry to be cautious. I think we may safely leave them to themselves and push on now deeper into the mine."

Acting upon this advice, the party stole silently away into the darkness, leaving the Somali warriors struggling desperately with one another. A trudge of nearly half a mile brought them to a point which seemed to be the farthest limit of the mine, for here galleries ran in every direction, and a glance at the rough surfaces of the walls showed that the workings had been deserted in a hurry, and not because gold was no longer to be found. Indeed, had it been possible, the three Englishmen would have gladly stayed to investigate the matter, for there were numerous interesting relics scattered about. But to delay then might have brought disaster to the party, and, therefore, they at once began to search for an exit.

"I feel sure we are not far from the open air," cried Jim, suddenly coming to a stop in the centre of a wide space, from which the tiny galleries cut into the hill. "Come here, and you will feel quite a draught blowing upon your heads, and——By Jove! Look at my torch!"

He held the brand above his head, and as he did so the dull red end began to glow brightly, and then, fanned by an invisible stream of air which played upon it, it burst into a brilliant flame, which effectually lit up the surroundings.

"A grand find, my boy!" shouted the colonel, for the first time showing some trace of excitement. "By the aid of that flaring brand we shall find our way to liberty. Push on, and when you see the light die down, you will know at once that we are moving in the wrong direction."

Jim needed no further encouragement, but, with his rifle grasped in one hand, strode forward, keeping his eye fixed upon the torch. And all the while he could feel the cold air blowing upon his face as it rushed into the workings through the ventilating shaft. Soon he came to a large square orifice, and entering it without hesitation, he went on till almost stopped by the pressure of the atmosphere. Following him closely, his companions were struck with wonder at the draught and watched in amazement as their torches kindled even brighter and sent long flames to the roof above.

"It is almost beyond belief," murmured John Margetson, breaking in upon the silence, "and I cannot realize how it is that the ventilation of the mine is managed. In a coal-pit there would be an up-cast and a down-cast shaft, with some arrangement at the former to cause the air to rush in that direction. But here we have come across nothing of the sort."

"It would take a week to discover the cause," answered the colonel, "but I have been through similar mines, and have come to the conclusion that the people who constructed them were most capable engineers. Hullo! What's that?"

As he spoke, the party came to an abrupt halt, and gave vent to cries of delight, for away ahead of them was a square patch of light, the goal for which they had been aiming.


CHAPTER XX

BACK TO THE COAST

"The exit! A means by which we may make good our escape from the mine, leaving the enemy utterly baffled!" shouted the colonel, as the square of brilliant light suddenly came into view, permitting, for the second time since his rescue from the Mullah's village, his usual composure to give way to the excitement of the moment. "Phew! What a breeze! It is as much as one can do to force a path towards the opening, for the draught comes singing in like a magnified gale, and fairly makes one stagger."

"Clever beggars, those old fellows who engineered the concern," gasped John Margetson, turning his face from the stream of air, so as to breathe more freely. "This is undoubtedly their ventilating shaft; and, George! how fond they must have been of a breeze. The hottest day in the tropics would be cool if spent in this tunnel, while in the winter——"

"A case of freezing," laughed the colonel. "The gale fairly sweeps and rushes in, and the atmosphere must reach to the farthest corner and nook of the mine, and clear it thoroughly. It is marvellous."

"It is fine, I admit," said Jim at this moment, joining in the conversation curtly; "but talking will not help us to get away from those fellows—will it, father?"

"Quite right! The lad speaks the truth, and we deserve to be reproved," was the smiling answer. "There is a time for everything, and at the present moment we have to think of our lives, and of the comrades whom we hope to join. But I will return here one of these days, when the Mullah has had his licking; and then how I shall enjoy exploring every inch of this place! But forward! What is the next move, Jim?"

"Let us get to the opening and take a look out, father. Till then I cannot say. We may find that the Somalis are already there, expecting our arrival, and in that case we shall have to retire to the workings again. If not, we must hold a council, and discuss what we must do to get to the zareba. Of course, we might make for the coast alone; but, then, that would be leaving my friend in the lurch, for he is waiting for us patiently."

"It would be the act of cowards," cried the colonel. "Our duty is to save ourselves, and to join hands with this gallant young fellow who has accompanied you into the country. Let us get ahead, my dear lad, for I must admit that this tunnel, at first so cool and invigorating, is now somewhat too cold for my liking. And then, the breeze comes in with such a rush that it is difficult to breathe, and talking is no easy matter."

"Then on we go," said Jim shortly, turning to the opening at once, from which, like his companions, he had been glad to keep his face away.

With torches held aloft, and spouting long streams of brilliant flame from their glowing ends, the little party sped on up the incline which led to the patch of daylight, their thoughts all the while bent upon the possible chances of ultimate escape. All realized that they had perhaps a thousand fanatical foes to deal with, and that many, many miles of rolling country intervened between themselves and the zareba away in the desert. Could they hope to make their way there without discovery? Was it not more than likely that before their weary feet had carried them more than a tenth of the distance, these fierce warriors would be upon them? But there was little use in imagining such things, and as nothing could be known for certain till the opening of the air-shaft was reached, they all hastened forward at as fast a pace as possible, gasping for air, with bodies leaning forward upon the column of wind pouring into the mine, fighting their way through its very centre.

"Hurrah!" cried Jim at length, as his hand came in contact with the solid arch of masonry which marked the entrance. "The open sky again. And now for a look round."

"Be cautious, master," came Ali's voice at this moment. "You have told me that these men who cry to Allah have scattered in search of the runaways. It may well be that some are even now close at hand, and will see you the instant your head appears. Be careful, therefore, I beg of you, for we cannot hope for such good fortune a second time."

"He needs no warning, this leader of ours," said John Margetson, halting beside our hero. "Has he not already shown his cuteness? Leave him to manage the matter alone, friend Ali."

"The words are filled with truth, sahib, and I am sorry," answered the native follower humbly. "I should know of his caution and wisdom even better than you do, seeing that I have marched beside him for many a day. But this danger has made me nervous. Never in my life before have I been in such peril, not even when the tribe attacked us in the pass on our way hither. Let my fears be my excuse, and forgive me. From this moment I shall maintain silence."

Jim very cautiously looked about him, pushing the blades of grass aside to enable him to see clearly. As there were no trees or bushes to obstruct the view, he was soon able to inform his comrades that not a single one of the enemy was in sight.

"They are all on the other side of the hill, rushing into the workings," he said with a smile of relief; "and now it becomes a question as to whether we should move in the direction of the desert, or whether we should remain here till matters have calmed down. This is too serious a decision for me to arrive at alone, and therefore I call all of you in to help me."

"Hum, a very difficult situation," said the colonel, pushing his way to the front and carefully surveying the surrounding country. "I see hills and valleys for a few miles, and then, as you have told me, a dead level extends to the zareba. This is the most dangerous point in our escape, for if we leave the mine, we throw comparative safety away. On the other hand, we cannot hope to remain here for long. Our provisions will soon become exhausted, and, moreover, once having overcome their fears, and having dared to enter the workings, these Somali warriors will penetrate to its farthest corners in search of their prisoners. Be sure of this: if the news of an advancing English column has angered the Mullah, this impudent and successful attempt to rescue prisoners from under his very eyes will rouse him to fury, and he will turn aside from the invading force in order to capture us. I confess that I hesitate. Here is a haven for a time. Out there, sunny and sweet as the country looks, it promises disaster."

"He who hesitates is lost," whispered John Margetson in his ear. "Listen to me, colonel; and you, too, Jim. To remain here is impossible. That is how I read it, for in an hour we shall be discovered by the searchers. Therefore, there can be no question. That is our way. Forward, my friends."

He pointed across the rolling expanse of grass, and would have emerged from the shaft, had not Jim detained him.

"Steady," he said quietly. "To hop out there into the open may be to commit the greatest of errors. A glance at you would convince one of the enemy that you are the escaping sailor; and then what a shout there would be!"

"Well? That would be the end of the matter."

"Quite so," responded Jim coolly. "But look at me. Am I not like the average Somali warrior?"

"Jove! The lad has a way to help us," shouted the colonel. "Silence while we listen to him. A Somali, my boy? Why, your disguise is undoubtedly excellent."

"Then I shall take advantage of the fact, father. Stay here, all of you, while I slip out. If I am seen, I shall be just one of the Mullah's followers, and all the while shall be on the look-out so as to see how we can best escape. Ta, ta. Wait till I return."

Before they could stretch out a friendly arm to detain him, Jim was outside the shaft, and was running up the slope of the hill. Anxiously did his comrades await his return, and more than once they were tempted to throw caution to the winds, and, giving way to their impatience, to rush into the open in search of their leader. But the calmness of the colonel held them back.

"Trust the lad," he said, his head held proudly in the air. "He has done as well as any man, and has shown that he has pluck and plenty of brains. Give him a full half-hour before we make any movement. Ah, what are those sounds?"

"The dogs in search of us," said Ali, placing his hand to his ear, and facing down the shaft. "These walls carry the sound as does the tube which they have in Aden. Have I not listened at one end to hear the sound of a comrade's voice? Have little fear, masters, for those men will hardly dare to follow us into this shaft."

"Hush! Here is someone coming towards us!" exclaimed the colonel, in a warning whisper at this moment. "I think it is Jim; but it may not be. He is evidently hunting for the entrance."

"It is the lad, sure enough," cried John Margetson, staring out of the shaft. "Look at the condition of his linen clothing. No self-respecting follower of Allah would dare to go abroad in such a dress. He is travel-soiled, and there can be no mistake as to his identity. I shall call to him."

Thrusting his arm clear of the opening, he waved it, and called gently to Jim. A second or two later Jim appeared at the entrance of the shaft, his dusky features radiant with smiles.

"Good news!" he cried eagerly. "Not one of the enemy on this side, so far as I have been able to observe, but all are in the ravine beyond, trying to screw up their courage to enter the mine as some of their comrades have done."

"Then they do not suspect that we are on the farther side," said the colonel, in tones of relief. "Nevertheless, the question of escape is still one of difficulty."

"I think not, father," answered Jim quietly. "We have a clear field before us, and scarcely forty miles to cover."

"But, good gracious! that will take us a day and a half at least," cried his parent.

"On foot—yes," said Jim gaily. "But on horseback, say a day at the most."

"Horseback! What do you mean?" burst in those who were listening to him, eagerly pressing about their young leader.

"Listen," was the smiling rejoinder. "I said that the followers of the Mullah were on the farther side of the hill, but I did not tell you that they had taken their animals to the ravine. Obviously, in such a small place, there would some overcrowding, for there is not too much room for the warriors themselves."

"Then where are they, my boy?" demanded the colonel.

"Come with me," was Jim's quiet answer, "but be careful not to show yourselves over the corner of the hill. The horses are grazing quietly in a little nook, a small valley which cuts into this long hill, and they are practically unwatched. That was a point about which I took a deal of trouble, and I ascertained without a doubt that only one man was stationed as a guard over the beasts. He, like his comrades, is all eagerness to help in our capture, and as I watched him, he was for ever staring into the ravine, and shouting words of encouragement to his fellows. He is the only man we have to fear at the present moment."

"Then he is the only one who shall taste one of our bullets," said John Margetson brusquely. "This fellow must not be allowed to give the alarm, and though I do not like the action, still it is imperative that we should shoot him. Otherwise he will give the alarm, and we shall have the whole host galloping after us."

"Running, you mean," replied Jim, with an easy laugh. "You see, we want more than a few ponies. A dozen are useless to us, for the remainder would carry the enemy in the same direction, and a long chase is a hard one, you know."

"But you don't propose——" gasped the colonel, staring at his son in bewilderment.

"Oh, yes, I do, father! If we are to escape, we shall have to take the bulk of the ponies for a few miles with us. A mile would not do, for these natives can run very fast. But after, say five miles, all but a very few would have fallen off, and the remainder we could easily account for. If we ride away, and leave the animals to the enemy, we shall be captives before the afternoon."

For a minute all stared at their young leader in amazement at the daring of his plan; then smacking his thigh, as if to give expression to his thoughts, John Margetson broke the silence.

"The Mullah will die of rage!" he gasped, while a smile of delight lit up his sun-tanned features. "Never before has he been so treated, and now to see his prisoners ride away, taking every horse he possesses, well——"

Evidently the thought was too much for the gallant mate, for he lapsed into silence, and writhed, as if his feelings were too much for him. As for the colonel, with the keenness of a trained soldier, he at once grasped the importance of the proposed movement.

"It is a capital plan," he said, with decision. "Every pony must come with us, and this fellow who watches them must be shot without mercy. Give me your rifle, Jim. I am too old a campaigner to have any qualms, and in such a case as this the act is justified. Now, what next?"

"Forward," said Jim quietly. "When we reach the top of the hill, Ali will stop where he is, and we others shall turn to the right. Thirty yards from Ali, John Margetson will come to a stop; another interval, and father will do the same. All will wait till I am in position. I shall wave my arm, and then we shall all move to the ponies. Select a couple of the finest, and tie their halters together. Then mount, and set the remainder in motion. They are well-trained beasts, and will give us no difficulty."

A glance was sufficient to show that his comrades comprehended his words, and at once turning, Jim led the way to the top of the rise.

"Ah!" an exclamation burst from all of the fugitives at the sight of some two hundred horses grazing in a small valley below.

"All the mounted men that the Mullah happens to have within call," murmured John Margetson. "No doubt the remainder are at the attack of the zareba. Now for the fellow who is looking after the horses."

"He has gone to take a look at his comrades," said Jim. "Forward again. Ali, you stay where you are."

Turning to the right, the three Englishmen at once hurried forward, and obedient to the orders of their young leader, John Margetson and the colonel halted when they had gained the correct distance. Jim kept on till he was at a point slightly beyond the horses. Waiting only to make sure that the animals were now surrounded, he waved his hand to his comrades and at once walked quietly towards two spirited-looking ponies, which promised to be amongst the strongest and swiftest there.

"Likely little beggars," he said to himself. "If they will allow me, I will become their owner for the time being."

A few paces brought him beside one of the animals, and with a bound he was in the saddle. Then grasping the halter of the other, he made a turn with it through the bridle of the pony he rode. Then he began to round up that part of the troop between him and his comrades.

"Look out!" came a shout in the colonel's voice; and turning swiftly, Jim saw a figure bounding across the grass towards him. Snap, bang! went a rifle, and a bullet discharged by the colonel whistled past the head of the pursuing Somali warrior. Bang! A second had no better effect, and ere a third could be attempted the man was upon our hero. Quick as lightning Jim dived his hand into his waistcloth, only to discover that his father had his revolver. He was apparently unarmed, while the Somali bore a flashing spear, and a huge sword at his girdle. "Ah, the sword!" thought Jim, and instantly recollected that he had thrust the weapon into the belt tied about his left forearm.

How it happened Jim never knew, but in the shortest space of time he was riding forward, driving part of the troop before him, while behind, huddled upon his face upon the grass, was the Somali warrior, a murmured "Allah" on his dying lips.

"A great stroke! Bravely and coolly done!" shouted the colonel, who had looked on anxiously, expecting the worst to happen, and blaming himself for his want of skill. "A running man is no easy object when one is mounted upon a fresh pony such as his; but all's well. It was a stroke! The lad has a head, and can look well to himself. I thought the spear was through him, and almost shouted, but he ducked at the very instant, and then—ah, I saw the blade go well home. But those fellows may have heard the shots, and if so, we shall soon be followed."

"Forward!" came Jim's voice at this moment; and instantly all began to urge the troop of animals into a trot. Leaping from their saddles, they picked stones from the earth and then pelted the beasts, shouting at them till their trot broke into a gallop.

"Now keep them to it, and if they try to stop, make a rush at them," shrieked John Margetson, sitting his pony in an attitude which showed clearly that he was no horseman. "Forward! To the zareba!"

It was a time of wild excitement, and each of the fugitives entered into the spirit of it thoroughly. Exhilarated by the quick movement over the rolling hills and valleys, with the smell of the horses in their nostrils, and the dust of four hundred heels in their eyes, they raced over the grass, driving the frantic animals before them. A thunderous sound filled the air as the animals galloped, but loud as it was it failed to drown that shout which came from behind.

"Allah! Allah! They have escaped us, and are riding away! Back! Leave the mine, and run! Money and a high place will be given to those who come up with the infidel!"

It was the Mullah who had heard the shots aimed at the sentry, and had climbed to the top of the hill to ascertain the cause.

"Our friend, the Mullah, my late master," shouted the colonel, looking grimly over his shoulder. "Let them run, for to those who happen to come in touch with us we will give more than the Mullah can promise. Death to them, my friends! Forward, for liberty and comrades are there."

Waving his weapon in the air, he looked at each of his comrades in turn, and smiled at them encouragingly. Then, with a shout at the animals directly in front of him, he sent them ahead at an even greater pace.

An hour later, when the little band of fugitives turned in their saddles, and brought the horses to a standstill, not one of the Mullah's followers was in sight, all having fallen out from the chase.

"We'll give the poor beasts a breather now," said Jim, dropping to the ground and going to his father's side. "We have put a good ten miles between us and the enemy, and I fancy we can say 'good-bye' to them."
