Jacques Paganel proceeded from admiration to ecstasy. Exclamations of delight continually escaped his lips, to the astonishment of the Patagonian, who thought it very natural that there should be birds in the air, swans on the lakes, and grass on the prairies. The geographer had no reason to regret his walk, or complain of its length. He scarcely believed himself started, or that the encampment would soon come in sight.

This tolderia was at the bottom of a narrow valley among the mountains. Here in huts of branches lived thirty wandering natives, grazing large herds of milch cows, sheep, cattle and horses. Thus they roamed from one pasture to another, always finding a repast ready for their four-footed companions.

GLENARVAN GOING TO MARKET.

Thalcave took upon himself the negotiation, which was not long. In return for seven small Argentine horses, all saddled, a hundred pounds of dried meat, a few measures of rice, and some leathern bottles for water, the Indians received twenty ounces of gold, the value of which they perfectly understood. Glenarvan would have bought another horse for the Patagonian, but he intimated that it was unnecessary.

The bargain concluded, Glenarvan took leave of his new "providers," as Paganel expressed it, and returned to the encampment. His arrival was welcomed by cries of joy at sight of the provisions and horses. Every one ate with avidity. Robert partook of some nourishment; he had almost entirely regained his strength, and the remainder of the day was passed in perfect rest. Various subjects were alluded to: the absent dear ones, the Duncan, Captain Mangles, his brave crew, and Harry Grant who was, perhaps, not far distant.

As for Paganel, he did not leave the Indian. He became Thalcave's shadow, and could not remain quiet in the presence of a real Patagonian, in comparison with whom he would have passed for a dwarf. He overwhelmed the grave Indian with Spanish phrases, to which the latter quietly listened. The geographer studied this time without a book, and was often heard repeating words aloud.

"If I do not get the accent," said he to the major, "you must not be angry with me. Who would have thought that one day a Patagonian would teach me Spanish!"


CHAPTER XVI.

NEWS OF THE LOST CAPTAIN.


At eight o'clock the next morning Thalcave gave the signal for departure. The slope was gradual, and the travelers had only to descend a gentle declivity to the sea.

When the Patagonian declined the horse that Glenarvan offered him, the latter thought that he preferred to go on foot, according to the custom of certain guides; and indeed, his long legs ought to have made walking easy. But he was mistaken.

At the moment of departure Thalcave whistled in a peculiar manner. Immediately a magnificent Argentine horse, of superb form, issued from a small wood near by, and approached at the call of his master. The animal was perfectly beautiful. His brown color indicated a sound, spirited and courageous beast. He had a small and elegantly poised head, widely opening nostrils, a fiery eye, large hams, swelling withers, broad breast, long pasterns, in short, all the qualities that constitute strength and suppleness. The major, like a perfect horseman, admired unreservedly this specimen of the horses of the plains. This beautiful creature was called Thaouka, which means "bird" in the Patagonian language, and he justly merited this appellation.

A FRESH START.

When Thalcave was in the saddle, the horse pranced with spirited grace, and the Patagonian, a skillful rider, was magnificent to behold. His outfit comprised two weapons of the chase, the "bolas" and the lasso. The bolas consists of three balls tied together by a leathern string, which are fastened to the front of the saddle. The Indians frequently throw them the distance of a hundred paces at the animal or enemy that they are pursuing, and with such precision that they twist about their legs and bring them to the ground. It is, therefore, in their hands a formidable instrument, and they handle it with surprising dexterity. The lasso, on the contrary, does not leave the hand that wields it. It consists simply of a leathern thong thirty feet in length, terminating in a slip-noose which works upon an iron ring. The right hand throws the slip-noose, while the left hand holds the remainder of the lasso, the end of which is firmly tied to the saddle. A long carbine in a sling completed the Patagonian's armament.

Thalcave, without observing the admiration caused by his natural grace, ease and courage, took the lead, and the party advanced, now at a gallop, and now at a walk, for their horses seemed entirely unaccustomed to trotting. Robert mounted with much boldness, and speedily convinced Glenarvan of his ability to keep his seat.

On issuing from the gorges of the Andes, they encountered a great number of sand-ridges, called "medanos," real waves incessantly agitated by the wind, when the roots of the herbage did not confine them to the earth. This sand is of an extreme fineness; and, at the least breath, they saw it float away in light clouds, or form regular sand-columns which rose to a considerable height. This spectacle caused pleasure as well as annoyance to the eyes. Pleasure, for nothing was more curious than these columns, wandering over the plain, struggling, mingling, sinking and rising in inexpressible confusion; and annoyance, since an impalpable dust emanated from these innumerable medanos and penetrated the eyelids, however tightly they were closed.

This phenomenon continued during a great part of the day. Nevertheless, they advanced rapidly, and towards six o'clock the Andes, forty miles distant, presented a darkish aspect already fading in the mists of the evening.

The travelers were a little fatigued with their journey, and, therefore, saw with pleasure the approach of the hour for retiring. They encamped on the shores of a turbulent stream, enclosed by lofty red cliffs. Toward noon of the next day, the sun's rays became very oppressive, and at evening a line of clouds on the horizon indicated a change in the weather. The Patagonian could not be deceived, and pointed out to the geographer the western portion of the sky.

"Good, I know," said Paganel, and addressing his companions: "A change in the weather is about to take place. We shall have a 'pampero.'"

TALKING LIKE A BOOK.

He explained that this pampero is frequent on the Argentine Plains. It is a very dry wind from the southwest. Thalcave was not mistaken, and during the night, which was quite uncomfortable for people sheltered with a simple poncho, the wind blew with great violence. The horses lay down on the ground, and the men near them in a close group. Glenarvan feared they would be delayed if the storm continued; but Paganel reassured him after consulting his barometer.

"Ordinarily," said he, "this wind creates tempests, which last for three days; but when the barometer rises as it does now, you are free from these furious hurricanes in a few hours. Be assured, then, my dear friend; at break of day the sky will have resumed its usual clearness."

"You talk like a book, Paganel," replied Glenarvan.

"And I am one," replied Paganel, "which you are free to consult as much as you please."

He was not mistaken. At one o'clock in the morning the wind suddenly subsided, and every one was able to enjoy an invigorating sleep. The next morning they rose bright and fresh, especially Paganel, who displayed great cheerfulness and animation.

During this passage across the continent, Lord Glenarvan watched with scrupulous attention for the approach of the natives. He wished to question them concerning Captain Grant, by the aid of the Patagonian, with whom Paganel had begun to converse considerably. But they followed a path little frequented by the Indians, for the trails over the Pampas, which lead from the Argentine Republic to the Andes, are situated too far to the north. If by chance a wandering horseman appeared in the distance, he fled rapidly away, little caring to come in contact with strangers.

However, although Glenarvan, in the interest of his search, regretted the absence of the Indians, an incident took place which singularly justified the interpretation of the document.

Several times the course pursued by the expedition crossed paths on the Pampas, among others quite an important road—that from Carmen to Mendoza—distinguishable by the bones of such animals as mules, horses, sheep and oxen, whose remains were scattered by the birds of prey, and lay bleaching in the sun. There were thousands of them, and, without doubt, more than one human skeleton had added its bones to those of these humbler animals.

Hitherto Thalcave had made no remark concerning the line so rigorously followed. He understood, however, that if they kept no definite course over the Pampas, they would not come to cities or villages. Every morning they advanced towards the rising sun, without deviating from the straight line, and every evening the setting sun was behind them. In his capacity of guide, Thalcave must, therefore, have been astonished to see that not only he did not guide them, but that they guided him. Nevertheless, if he was astonished, with the reserve natural to the Indians he made no remark. But to-day arriving at the above-mentioned road, he stopped his horse, and turned towards Paganel.

"Road to Carmen," said he.

"Yes, my good Patagonian," replied the geographer, in his purest Spanish; "road to Carmen and Mendoza."

"We do not take it?" resumed Thalcave.

"No," answered Paganel.

"And we are going——?"

"Always to the east."

"That is going nowhere."

"Who knows?"

Thalcave was silent, and gazed at the geographer with profound surprise. He did not admit, however, that Paganel was joking the least in the world. An Indian, with his natural seriousness, never imagines that you are not speaking in earnest.

"You are not going to Carmen then?" he added, after an instant of silence.

A PROFESSORIAL DIFFICULTY.

"No," replied Paganel.

"Nor to Mendoza?"

"No."

At this moment Glenarvan, rejoining Paganel, asked what Thalcave said, and why he had stopped.

When he had told him, Glenarvan said,—

"Could you not explain to him the object of our expedition, and why we must always proceed toward the east?"

"That would be very difficult," answered Paganel, "for an Indian understands nothing of geography."

"But," said the major seriously, "is it the history, or the historian, that he cannot understand?"

"Ah, MacNabb," said Paganel, "you still doubt my Spanish!"

"Try, my worthy friend."

"Very well."

Paganel turned to the Patagonian, and began a discourse, frequently interrupted for want of words and from the difficulty of explaining to a half-ignorant savage details which were rather incomprehensible to him.

The geographer was just then a curious sight. He gesticulated, articulated, and exerted himself in a hundred ways, while great drops of sweat rolled down his face. When his tongue could no longer move, his arm came to his aid. He dismounted, and traced on the sand a geographical map, with lines of latitude and longitude, the two oceans, and the road to Carmen. Never was professor in such embarrassment. Thalcave watched these manœuvres without showing whether he comprehended or not.

The lesson in geography lasted more than half an hour. At last Paganel ceased, wiped his face, which was wet with perspiration, and looked at the Patagonian.

"Did he understand?" inquired Glenarvan.

"We shall see," replied Paganel; "but, if he did not, I give it up."

"PERHAPS!"

Thalcave did not stir. He no longer spoke. His eyes were fixed upon the figures traced on the sand, which the wind was gradually effacing.


An important road—that from Carmen to Mendoza—distinguishable by the bones of such animals as mules, horses, sheep and oxen, whose remains were scattered by the birds of prey, and lay bleaching in the sun.


"Well?" asked Paganel.

Thalcave did not appear to hear him. Paganel already saw an ironical smile forming upon the lips of the major, and, wishing to save his reputation, had begun with renewed energy his geographical demonstrations, when the Patagonian stopped him with a gesture.

"You are searching for a prisoner?" he said.

"Yes," replied Paganel.

"And exactly on the line from the setting to the rising sun?" said Thalcave, indicating by a comparison, in the Indian manner, the course from west to east.

"Yes, yes, that is it!"

"And it is your God," said the Patagonian, "who has confided to the waves of the vast ocean the secrets of the prisoner?"

"God himself."

"May his will be accomplished then!" replied Thalcave, with a certain solemnity. "We will go to the east, and, if necessary, even to the sun."

Paganel, in his exultation over his pupil, immediately translated to his companions the replies of the Indian.

Glenarvan requested Paganel to ask the Patagonian if he had heard of any strangers falling into the hands of the Indians, which was accordingly done.

"Perhaps," replied the Patagonian.

As soon as this word was translated, Thalcave was surrounded by the seven travelers, who gazed at him with questioning looks. Paganel, excited and scarcely finding his words, resumed these interesting interrogatories, while his eyes, fixed upon the grave Indian, strove to anticipate his reply before it issued from his lips. Every word the Patagonian said he repeated in English, so that his companions heard the Indian speak, as it were, in their own language.

"And this prisoner?" inquired Paganel.

"He was a stranger," replied Thalcave slowly; "a European."

"You have seen him?"

"No, but he is mentioned in the accounts of the Indians. He was a brave man."

"You understand, my friends," said Paganel; "a courageous man!"

"My father!" cried Robert Grant.

Then, addressing Paganel:

"How do you say 'It is my father,' in Spanish?" he asked.

"Es mio padre," answered the geographer.

Immediately Robert, taking Thalcave's hands, said in a sweet voice,—

"Es mio padre!"

"Suo padre!" replied the Patagonian, whose look brightened.

He took the boy in his arms, lifted him from his horse, and gazed at him with the most curious sympathy. His intelligent countenance became suffused with a peaceful emotion.

But Paganel had not finished his inquiries. Where was this prisoner? What was he doing? When had Thalcave heard of him? All these questions thronged his mind at once. He did not have to wait long for answers, but learnt that the European was a slave of one of the Indian tribes that scour the plains.

"But where was he last?" asked Paganel.

"With the cazique Calfoucoura," answered Thalcave.

"On the line we have been following?"

"Yes."

"And who is this cazique?"

"The chief of the Poyuches Indians; a man with two tongues and two hearts."

A SCIENTIFIC BATH.

"That is to say, false in word and in deed," said Paganel, after translating to his companions this beautiful metaphor of the Indian language. "And can we rescue our friend?" he added.

"Perhaps so, if your friend is still in the hands of the Indians."

"And when did you hear of him?"

"A long time ago, and, since then, the sun has brought back two summers to the sky."

Glenarvan's joy could not be described. This answer coincided exactly with the date of the document. But one question remained to be asked.

"You speak of a prisoner," said Paganel; "but were there not three?"

"I do not know," replied Thalcave.

"And you know nothing of their actual situation?"

"Nothing."

This last word ended the conversation. It was possible that the three prisoners had been separated a long time. But the substance of the Patagonian's information was that the Indians spoke of a European who had fallen into their power. The date of his captivity, the place where he must have been, everything, even to the Patagonian phrase used to express his courage, related evidently to Captain Harry Grant.

Their progress was now somewhat slow and difficult; their next object being to reach and cross the river Colorado, to which at length their horses brought them. Here Paganel's first care was to bathe "geographically" in its waters, which are colored by a reddish clay. He was surprised to find the depth so great as it really was, this being the result of the snow having melted rapidly under the first heat of summer. The width likewise of this stream was so considerable that it was almost impossible for their horses to swim across; but they happily discovered a sort of weir-bridge, of wattles looped and fastened together, which the Indians were in the habit of using; and by its aid the little troop was enabled to pass over to the left bank, where they rested for the night.


CHAPTER XVII.

A SERIOUS NECESSITY.


They set out at daybreak. The horses advanced at a brisk pace among the tufts of "paja-brava," a kind of grass that serves the Indians as a shelter during the storms. At certain distances, but less and less frequent, pools of shallow water contributed to the growth of willows and a certain plant which is found in the neighborhood of fresh water. Here the horses drank their fill, to fortify themselves for the journey. Thalcave, who rode in advance, beat the bushes, and thus frightened away the "cholinas" (vipers), while the agile Thaouka bounded over all obstacles, and aided his master in clearing a passage for the horses that followed.


They set out at daybreak. The horses advanced at a brisk pace among the tufts of "paja-brava," a kind of grass that serves the Indians as a shelter during the storms.


Early in the afternoon, the first traces of animals were encountered—the bones of an innumerable drove of cattle, in whitened heaps. These fragments did not extend in a winding line, such as animals exhausted and falling one by one would leave behind them. Thus no one, not even Paganel, knew how to explain this chain of skeletons in a space comparatively circumscribed. He therefore questioned Thalcave, who was not at a loss for a reply.

"What is this?" they asked, after Paganel had inquired of the Indian.

"The fire of heaven," replied the geographer.

"What! the lightning could not have produced such a disaster," said Tom Austin, "and stretched five hundred head of cattle on the earth!"

But Thalcave reaffirmed it, and he was not mistaken; for the storms of the Pampas are noted for their violence.

At evening they stopped at an abandoned rancho, made of interlaced branches plastered with mud and covered with thatch. This structure stood within an inclosure of half-rotten stakes which, however, sufficed to protect the horses during the night against the attacks of the foxes. Not that they had anything to fear personally from these animals, but the malicious beasts gnawed the halters, so that the horses could escape.

A few paces from the rancho, a hole was dug which served as a kitchen and contained half-cooled embers. Within, there was a bench, a bed of ox-hide, a saucepan, a spit, and a pot for boiling maté. The maté is a drink very much in use in South America. It is the Indian's tea, consisting of a decoction of leaves dried in the fire, and is imbibed through a straw. At Paganel's request, Thalcave prepared several cups of this beverage, which very agreeably accompanied the ordinary eatables, and was declared excellent.

A CHANGE FOR THE WORSE.

The next day they resumed their journey towards the east. About noon a change took place in the appearance of the Pampas, which could not escape eyes wearied with its monotony. The grass became more and more scanty, and gave place to sickly burdocks and gigantic thistles; while stunted nettles and other thorny shrubs grew here and there. Heretofore, a certain moisture, preserved by the clay of the prairie, freshened the meadows; the vegetation was thick and luxuriant. But now a patchy growth, bare in many places, exposed the earth, and indicated the poverty of the soil. These signs of increasing dryness could not be mistaken, and Thalcave called attention to them.

"I am not sorry at this change," said Tom Austin; "to see always grass, nothing but grass, becomes tiresome before long."

"But where there is grass there is water," replied the major.

"Oh, we are not in want," said Wilson, "and shall find some river on our course."

However, when Wilson said that the supply of water would not fail he had not calculated for the unquenchable thirst that consumed his companions all that day; and, when he added that they would meet with some stream in their journey he had anticipated too much. Indeed, not only were rivers wanting, but even the artificial wells dug by the Indians were empty. On seeing these indications of dryness increase from mile to mile, Paganel asked Thalcave where he expected to find water.

"At Lake Salinas," replied the Indian.

"And when shall we arrive there?"

"To-morrow evening."

The natives ordinarily, when they travel on the Pampas, dig wells, and find water a few feet below the surface; but the travelers, destitute of the necessary implements, could not employ this expedient. It was therefore necessary to obtain a supply in some other way, for, if they did not absolutely suffer from the tormenting desire for drink, no one could entirely allay his thirst.

At evening they halted, after a journey of thirty miles. Every one relied upon a good night to recruit himself after the fatigues of the day; but they were greatly annoyed by a very persistent swarm of mosquitoes, which disappeared, however, after the wind changed.

If the major preserved his calmness in the midst of the petty annoyances of life, Paganel, on the contrary, could not treat the matter so indifferently. He fought the mosquitoes, and sadly regretted the absence of his acid-water, which would have soothed the pain of their bites. Although the major endeavored to console him, he awoke in a very bad humor.

However, he was very easily persuaded to set out at daybreak, for it was important to arrive at Lake Salinas the same day. The horses were very much exhausted: they were dying of thirst; and, although their riders had denied themselves on their account, still their share of water had been very limited. The dryness was to-day even greater, and the heat no less intolerable, with the dusty wind, the simoom of the Pampas.

INDIANS AHEAD!

During the day the monotony of the journey was interrupted. Mulready, who rode in advance, turned back, signaling the approach of a party of Indians. This meeting elicited different opinions. Glenarvan thought of the information that these natives might furnish concerning the shipwrecked seamen of the Britannia. Thalcave, for his part, scarcely enjoyed meeting in his journey the wandering Indians of the plains. He considered them plunderers and robbers, and only sought to avoid them. According to his orders, the little party collected together, and made ready their fire-arms. It was necessary to be prepared for any emergency.

The Indian detachment was soon perceived. It consisted of only ten men, which fact reassured the Patagonian. They approached within a hundred paces, so that they could be easily distinguished. Their high foreheads, prominent rather than receding, their tall forms, and their olive color, showed them to be magnificent types of the Indian race. They were clad in the skins of guanacos, and carried various weapons of war and the chase, while their dexterity in horsemanship was remarkable.

Having halted, they appeared to hold a conference, crying and gesticulating. Glenarvan advanced toward them; but he had not proceeded two yards, when the detachment wheeled about and disappeared with incredible swiftness. The tired horses of the travelers could never have overtaken them.

"The cowards!" cried Paganel.

"They fly too fast for honest men," said MacNabb.

"What are these Indians?" inquired Paganel of Thalcave.

"Gauchos!" replied the Patagonian.

"Gauchos!" repeated Paganel, turning toward his companions, "Gauchos! We had no need, then, to take such precautions. There was nothing to fear!"

"Why?" asked the major.

"Because the Gauchos are inoffensive peasants."

"Do you think so, Paganel?"

"Certainly. They took us for robbers, and fled."

Glenarvan was quite disappointed in not speaking with them, as he expected to obtain additional tidings of the lost sailors; but it was necessary to push on, if they would reach their destination that evening.

At eight o'clock Thalcave, who had gone a little in advance, announced that the lake so long desired was in sight. A quarter of an hour afterward the little party descended the high banks. But here a serious disappointment awaited them,—the lake was dry!


CHAPTER XVIII.

IN SEARCH OF WATER.


Lake Salinas terminates the cluster of lagoons that adjoin the Ventana and Guamini mountains. Numerous expeditions are made to this place to obtain supplies of salt, with which these waters are strongly impregnated. But now the water had evaporated under the heat of the sun, and the lake was only a vast glittering basin.

When Thalcave announced the presence of a drinkable liquid at Lake Salinas, he meant the streams of fresh water that flow from it in many places. But at this time its affluents were as dry as itself. The burning sun had absorbed everything. Hence, the consternation was general when the thirsty party arrived at the parched shores of Lake Salinas.

It was necessary to take counsel. The little water in the leathern bottles was half spoiled, and could not quench their thirst, which began to make itself acutely felt. Hunger and fatigue gave place to this imperative want. A "roukah," a kind of upright tent, of leather, which stood in a hollow, and had been abandoned by the natives, served as a refuge for the travelers, while their horses, stretched on the muddy shores of the lake, ate the saline plants and dry reeds, although reluctantly.

When each had sat down in the roukah, Paganel asked Thalcave's advice as to what was best to be done. A rapid conversation, of which Glenarvan caught a few words, ensued between the geographer and the Indian. Thalcave spoke calmly, while Paganel gesticulated for both. This consultation lasted a few minutes, and then the Patagonian folded his arms.

"What did he say?" inquired Glenarvan. "I thought I understood him to advise us to separate."

"Yes, into two parties," replied Paganel. "Those of us whose horses are so overcome with fatigue and thirst that they can scarcely move will continue the journey as well as possible. Those who are better mounted, on the contrary, will ride in advance, and reconnoitre the Guamini River, which empties into Lake San Lucas. If there is sufficient water there, they will wait for their companions on the banks of the stream; if not, they will return to save the rest a useless journey."

"And then?" asked Tom Austin.

"Then we must go southward to the first branches of the Ventana mountains, where the rivers are numerous."

"The plan is good," replied Glenarvan, "and we will follow it without delay. My horse has not suffered so much yet from want of water, and I offer to accompany Thalcave."

"Oh, my lord, take me!" cried Robert, as if a pleasure excursion were in question.

"But can you keep up with us, my child?"

"Yes, I have a good beast that asks nothing better than to go in advance. Will you, my lord? I beseech you!"

"Come then, my boy," said Glenarvan, delighted not to be separated from Robert. "And we three," he added, "will be very stupid if we do not discover some clear and fresh stream."

"And I?" said Paganel.

"Oh, you, my dear Paganel!" replied the major, "you will remain with the reserve detachment. You know the course, the Guamini River, and the Pampas, too well to abandon us. Neither Wilson, Mulready, nor myself are capable of rejoining Thalcave at his rendezvous, unless we advance confidently under the guidance of the brave Jacques Paganel."


"Poor father!" exclaimed Robert; "how he will thank you when you have found him!" And, so saying, he took his lordship's hand and pressed it to his lips.


"I resign," said the geographer, very much flattered to obtain a higher command.

"But no distractions!" added the major. "Do not lead us where we have nothing to do, and bring us back to the shores of the Pacific!"

"You would deserve it, my intolerable major," said Paganel, smiling. "But tell me, my dear Glenarvan, how will you understand Thalcave's language?"

"I suppose," answered Glenarvan, "that the Patagonian and I will not need to talk. Besides, with the few Spanish words that I know, I shall succeed well enough on an emergency in giving him my opinion and understanding his."

"Go then, my worthy friend," replied Paganel.

"Let us eat first," said Glenarvan, "and sleep till the hour of departure."

They ate supper without drink, which was rather unrefreshing, and then fell asleep. Paganel dreamed of torrents, cascades, streams, rivers, ponds, brooks, nay even full bottles, in short, of everything which generally contains water. It was a real nightmare.

The next morning at six o'clock the horses were saddled. They gave them the last drink of water left, which they took with more dislike than pleasure, for it was very nauseating. The three horsemen then mounted.

"Au revoir!" said the major, Austin, Wilson, and Mulready.

Soon the Patagonian, Glenarvan, and Robert (not without a certain throbbing of the heart) lost sight of the detachment confided to the sagacity of the geographer.

THE YOUNG SAILOR ON HORSEBACK.

Thalcave was right in first proceeding towards the Guamini, since this stream lay on the prescribed course, and was the nearest. The three horses galloped briskly forward. These excellent beasts perceived, doubtless, by instinct, whither their masters were guiding them. Thaouka, especially, showed a spirit that neither fatigue nor thirst could overcome. The other horses followed, at a slower pace, but incited by his example.

The Patagonian frequently turned his head to look at Robert Grant, and, seeing the young boy firm and erect, in an easy and graceful position, testified his satisfaction by a word of encouragement.

"Bravo, Robert!" said Glenarvan. "Thalcave seems to congratulate you. He praises you, my boy!"

"And why, my lord?"

"Because of the way you ride."

"Oh, I merely keep firm; that is all," replied Robert, who blushed with pleasure at hearing himself complimented.

"That is the main point, Robert," said Glenarvan; "but you are too modest, and I am sure you cannot fail to become an accomplished equestrian."

"Well," said Robert, "but what will papa say, who wishes to make a sailor of me?"

"The one does not interfere with the other. If all horsemen do not make good sailors, all sailors may certainly make good horsemen. To ride on the yards, you must learn to keep yourself firm. As for knowing how to manage your horse, that comes more easily."

"Poor father!" exclaimed Robert; "how he will thank you when you have found him!" And, so saying, he took his lordship's hand and pressed it to his lips.

"You love him well, Robert?"

"Yes, my lord; he was so kind to sister and me. He thought only of us, and every voyage brought us a memento of the countries he visited, and, what was better, tender caresses and kind words, on his return. Ah! you will love him too, when you know him! Mary resembles him. He has a sweet voice like her. It is singular for a sailor, is it not?"

"Yes, very singular, Robert," said Glenarvan.

"I see him still," replied the boy, as if speaking to himself. "Good and brave papa! He rocked me to sleep on his knees, when I was little, and kept humming an old Scottish song which is sung around the lakes of our country. I sometimes recall the air, but indistinctly. How we loved him, my lord! Well, I think one must be very young to love his father well."

"And old to reverence him, my child," replied Glenarvan, quite moved by the words that came from this young heart.

During this conversation, their horses had relaxed their pace and fallen behind the other; but Thalcave called them, and they resumed their former gait. It was soon evident, however, that, with the exception of Thaouka, the horses could not long maintain this speed. At noon it was necessary to give them an hour's rest.

Glenarvan grew uneasy. The signs of dryness did not diminish, and the want of water might result in disastrous consequences. Thalcave said nothing, but probably thought that if the Guamini was dry it would then be time to despair, if indeed an Indian's heart has ever experienced such an emotion.

They therefore kept on, and by use of whip and spur the horses were induced to continue their journey, but they could not quicken their pace. Thalcave might easily have gone ahead, for in a few hours Thaouka could have carried him to the banks of the stream. He doubtless thought of it, but probably did not like to leave his two companions alone in the midst of this desert, and, that he might not outstrip them, he forced Thaouka to lessen his speed. It was not, however, without much resistance, prancing and neighing, that Thalcave's horse consented to keep pace with the others. It was not so much the strength as the voice of his master which restrained him; the Indian actually talked to his horse; and the animal, if he did not answer, at least comprehended him. The Patagonian must have used excellent arguments, for, after "discussing" some time, Thaouka yielded, and obeyed his master's commands.

GAINED AT LAST.

But, if Thaouka understood Thalcave, Thalcave had none the less understood Thaouka. The intelligent animal, through his superior instincts, had perceived a moisture in the air. He inhaled it eagerly, and kept moving his tongue, as if it were steeped in a grateful liquid. The Patagonian could not be deceived; water was not far distant.

He therefore encouraged his companions by explaining the impatience of his horse, which the others were not long in understanding. They made a final effort, and galloped after the Indian.

About three o'clock a bright line appeared in a hollow of the plain. It trembled under the rays of the sun.

"Water!" cried Glenarvan.

"Water, yes, water!" cried Robert.

They had no more need to urge their horses. The poor beasts, feeling their strength renewed, rushed forward with an irresistible eagerness. In a few moments they had reached the Guamini River, and, saddled as they were, plunged to their breasts into the cooling stream. Their masters imitated their example, without reluctance, and took an afternoon bath which was as healthful as it was pleasant.

"Ah, how good it is!" said Robert, as he quenched his thirst in the middle of the river.

"Be moderate, my boy," said Glenarvan, who did not set a good example.

Nothing was heard but the sound of rapid drinking. As for Thalcave, he drank quietly, without hurrying, long and deeply, till they might perhaps fear that the stream would be drained.

"Well," said Glenarvan, "our friends will not be disappointed in their expectations. They are sure, on arriving at the Guamini, to find an abundance of clear water, if Thalcave leaves any!"

"But could we not go to meet them?" asked Robert. "We could spare them several hours of anxiety."

"Doubtless, my boy; but how carry the water? Wilson has charge of the water-bottles. No, it is better to wait, as we agreed. Calculating the necessary time, and the slow pace of the horses, our friends will be here at night. Let us, then, prepare them a safe shelter and a good repast."

Thalcave had not waited for Glenarvan's orders to search for a place to encamp. He had very fortunately found on the banks of the river a "ramada," a kind of inclosure designed for a cattle-fold and shut in on three sides. The situation was excellent for the purpose, so long as one did not fear to sleep in the open air; and that was the least anxiety of Thalcave's companions. Thus they did not seek a better retreat, but stretched themselves on the ground in the sun to dry their water-soaked garments.

"Well, since here is shelter," said Glenarvan, "let us think of supper. Our friends must be satisfied with the couriers whom they have sent forward; and, if I am not greatly mistaken, they will have no reason to complain. I think an hour's hunting will not be time lost. Are you ready, Robert?"

"Yes, my lord," replied he, with gun in hand.

AN EVENING'S SPORT.

Glenarvan had conceived this idea because the banks of the Guamini seemed to be the haunt of the game of the surrounding plains. "Tinamous," a kind of partridge, plovers called "teru-teru," yellow rails, and water-fowl of magnificent green were seen rising in flocks. As for quadrupeds, they did not make their appearance; but Thalcave, pointing to the tall grass and thick coppice, explained that they were hidden there. The hunters had only to take a few steps to find themselves in one of the best game-coverts in the world.
