The Naturalist on the Thames

EWELME--A HISTORICAL RELIC

At the head of one of the smaller Thames tributaries, a few miles from the river, lies Ewelme, the ancient Aquelma, so called from the springing waters which rise there. There are trout in the brook and excellent water-cresses higher up, which are cultivated scientifically. Also there was a political row in Gladstonian days over an appointment to the living. But the real interest of this exceptionally beautiful Thames-valley village is that it is a survival, almost unchanged, of a "model village" made in the time of the Plantagenets. As such it deserves a place in any history, even a "natural" history, which deals with the river.

The village lies at the foot of the Chiltern Hills, not far from Dorchester. The persons who made it a model village just before the Wars of the Roses were William de la Pole, the first Duke of Suffolk, and his Duchess, Alice, the grandchild of Geoffrey Chaucer. The Duke, as every one knows, was for years the leading spirit in England during the early part of the reign of Henry VI., whose marriage with Margaret of Anjou he arranged in the hope of putting an end to the disastrous war with France. His murder in mid-Channel--when his relentless enemies followed him out to sea, took him from the ship in which he was going into exile, and beheaded him on the thwarts of an open boat--was the forerunner of the most ghastly chapters of blood and vengeance in civil feud ever known in this country. But the grace and dignity of his home life in his palace at Ewelme, with his Duchess to help him, are less well known, though the evidences of it remain little altered at the present day.

EEL-TRAPS

Fish and flour go together as bye-products of nearly all our large rivers. The combination comes about thus: Wherever there is a water-mill, a mill cut is made to take the water to it. The larger the river, the bigger and deeper the mill cut and dam, unless the mill is built across an arm of the stream itself. This mill-dam, as every trout-fisher knows, holds the biggest fish, and where there are no trout, or few trout, it will be full of big fish, while in the pool below there are perhaps as many more. Of all the food fishes of our rivers the eel is really far the most important. He flourishes everywhere, in the smallest pools and brooks as well as in the largest rivers, and grows up to a weight of 9 lb. or 10 lb., and sometimes, though rarely, more. His price indicates his worth, and never falls below 10d. per lb. Consequently he is valuable as well as plentiful, and the millers know this well. On nearly all rivers the millers have eel-traps, some of the ancient sort being "bucks," made of withes, and worked by expensive, old-fashioned machinery like the mill gear. Another and most paying dodge of the machine-made order is worked in the mill itself, and makes an annexe to the mill-wheel.

I once spent an agreeable hour watching the making of barley meal and the catching of eels, literally side by side. It was sufficiently good fun to make me put my gun away for the afternoon, and give up a couple of hours' walk, with the chance of a duck, to watch the mill and eel-traps working.

They were both in a perfect old-world bye-end of the Thames Valley, in the meads at the back of the forgotten but perfect abbey of the third order at Dorchester, under the tall east window of which the River Thame was running bank full, fringed with giant poplars, from which the rooks were flying to look at their last year's nests in the abbey trees.

The mill was, as might be supposed, the Abbey Mill; but on driving up the lane I was surprised to see how good and large was the miller's house, a fine dwelling of red and grey brick; and what a length of frontage the old mill showed, built of wood, as most of them are, but with two sets of stones, and space for two wheels. Only one was at work, and that was grinding barley-meal--meal from nasty, foreign barley full of dirt; but the miller had English barley-meal too, soft as velvet and sweet as a new-baked loaf. Stalactites of finest meal dust hung from every nail, peg, cobweb, and rope end on the walls, fine meal strewed the floor, coarse meal poured from the polished shoots, to which the sacks hung by bright steel hooks, and on both floors ancient grindstones stood like monuments of past work and energy, while below and beside all this dust and floury dryness roared the flooded waters of the dam and the beating floats of the wheel. "Have you any eels?" I asked. "Come and see," said the miller.

He stopped his wheel, unbolted the door, and we looked up the mill dam, two hundred yards long, straight as a line, embanked by double rows of ancient yews, the banks made and the trees planted by the monks five hundred years ago. Then we stepped into the wheel-house, where the water, all yellow and foaming, was pouring into two compartments set with iron gratings below, on which it rose and foamed. Seizing a long pole with prongs like walrus teeth, the miller felt below the water on the bars. "Here's one, anyway," he said, and by a dexterous haul scooped up a monster eel on to the floor. In a box which he hauled from the dam he had more, some of 5-lb. weight, which had come down with the flood--an easy and profitable fishery, for the eels can lie in the trap till he hauls them out, and sell well summer and winter. It pays as well as a poultry yard. Once he took a 9-lb. fish; 2-1/2 lb. to 4 lb. are common.

The eel-trap on the old Thames mill stream is imitated in other places where there is no mill. Thus at Mottisfont Abbey on the Test an old mill stream is used to work an hydraulic ram, and also to supply eels for the house; the water is diverted into the eel-trap, and the fish taken at any time. Another dodge for taking eels, which is not in the nature of what is called a "fixed engine," is the movable eel-trap or "grig wheel." It is like a crayfish basket, and is in fact the same thing, only rather larger. They can be obtained from that old river hand, Mr. Bambridge, at Eton, weighted, stoppered, and ready for use, for 7s. 6d. each, and unweighted for 5s. They are neat wicker-work tunnels, with the usual contrivance at the mouth to make the entrance of the eels agreeable and their exit impossible. The "sporting" side of these traps is that a good deal of judgment is needed to set them in the right places in a river. Many people think that eels like carrion and favour mud. Mr. Bambridge says his experience is different, and his "advice to those about to fish" with this kind of eel-trap is suggestive of new ideas about eels. He says that "for bait nothing can beat about a dozen and a-half of small or medium live gudgeon, failing these large minnows, small dace, roach, loach, &c., though in some streams about a dozen good bright large lob worms, threaded on a copper wire and suspended inside, are very effective, and should always be given a trial. Offal I have tried but found useless, eels being a cleaner feeding fish than many are aware of; and feeding principally in gravelly, weedy parts, the basket should be well tucked up under a long flowing weed, as it is to these places they go for food, such as the ground fish, loach, miller's thumb, crayfish, shrimps, mussels, &c. When I worked a fishery near here, I made it a rule after setting the basket to well scratch the soil in front of the entrance with the boathook I used for lowering them, and firmly believe their curiosity was excited by the disturbed gravel. Choose water from four feet to six feet deep, and see basket lays flat. Every morning when picked up, lay them on the bank, pick out all weed and rubbish, and brush them over with a bass broom, keeping them out of water till setting again at dusk."

Eel-bucks, of which few perfect sets now remain, are the fixed engines so often seen on the Thames, and are a costly and rather striking contrivance, adding greatly to the picturesqueness of parts of the river. They are very ancient, and date from days when the "eel-run" was one of the annual events of river life. The eels went down in millions to the sea, and the elvers came up in such tens of millions that they made a black margin to the river on either side by the bank, where they swam because the current was there weakest. The large eels were taken, and are still taken, on their downward journey in autumn. It is then that the Thames fills, and at the first big rush of water the eels begin to descend to reach the mud and sands at the Thames mouth, where they spawn. They always travel by night, and it is then that the heavy eel-bucks are lowered. Often hundredweights are taken in a night, all of good size, one of the largest of which there is any record being one of 15 lb., taken in the Kennet near Newbury. In the "grig-wheels" they are taken as small as 3 oz. or 4 oz.; but in the bucks they rarely weigh less than 1 lb. The darkest nights are the most favourable. Moonlight stops them, and they do not like still weather. The upward migration of eels goes on from February till May on the Thames, but the regular "eel-fare" of the young grigs do not assume any great size till May, when as many as 1,800, about three inches long, were seen to pass a given point in one minute. So say the records. But who could have counted them so fast?

A few recent developments of the eel trade elsewhere show how valuable this may be. Quite lately the Danes discovered that the Lim-fiord and some other shallow Broads on the West Danish Coast were a huge preserve of eels. They began trawling there steadily, and have established a large and lucrative trade in them. On the Bann, in Ireland, eel catching is still done in a large way, and the fish shipped to London. But the most ancient and yet most modern of eel fisheries is on the Adriatic, at Comacchio, where lagoons 140 miles in circumference are stocked with eels, and eel breeding and exporting are carried out on a large scale. Even as early as the sixteenth century the Popes used to derive an income of £12,000 from this source.

SHEEP, PLAIN AND COLOURED

In the Thames Valley there are two very distinguished breeds of sheep--the Cotswolds at the head of the watershed, and the Oxford Downs, near Wallingford. Wallingford lamb is supposed to be the best in the market. There are also the Berkshire Downs sheep, but these are, I think, more obviously cross-bred, or else of the Hampshire breed. The Cotswold sheep are probably a very old breed. They are evidently the original of the woolly "baa-lamb" of the nursery, with long, fleecy wool. The Oxford Downs are a short-woolled sheep. One of the flocks of this breed has been improved by selection, mainly in regard to fecundity, to such an extent that I believe twins are the normal proportion among the lambs. The shepherds, as elsewhere on the large down farms, form a race apart. They are not always on the best of terms with the ordinary farm labourers, I notice. "The shepherd be a working against I," is a complaint I sometimes hear. The real reason is that the shepherd thinks, above all things, of his flock, and of finding them food. The feud between the keeper of sheep and the raiser of crops dates from the days of Cain and Abel.

I heard lately from a gentleman who very frequently occupies the honourable position of judge or steward at the leading agricultural shows, that it is proposed that in future no sheep sent to shows are to be allowed to have their coats rouged, and the judges are in future to make their decisions uninfluenced by the beauties of cosmetics. This decision comes as a great blow to the skilled hands in the business of the "improver," who, by long experience and a nice knowledge of the weaknesses of judges, had brought the art of "making up" pedigree sheep of any particular breed to something very nearly approaching the ideal of perfection. Their wool was clipped so artistically as to resemble a bed of moss, and this being elegantly tinted with rouge or saffron, the sheep assumed the hue of the pink or primrose, according to taste and fancy. The reason for the demand which now requires that the champions of the flock shall be shown "plain" and not coloured is not too technical to appeal to the general public. Those who know the acute anxiety with which the exhibitors of prize animals, from fancy mice to shorthorns, watch them "coming on" as the hour for the show approaches, will treat tenderly, even if they cannot condone, the little weaknesses into which the uses of rouge and saffron led them. When a Southdown which ought to have a contour smooth and rounded as a pear still showed aggravating little pits and hollows where there ought to be none, nothing was easier than to postpone clipping those undesirable hollows till the moment before the show, or if there were bumps where there should be no bumps, to shave the wool down close over them. Left to Nature, the newly-clipped wool would show a different tint from the rest of the fleece; but the rouge or saffron then applied made all things even, to the eye, and the judges to find out whether the animals were "level" or not had to feel them all over. Feeling every six inches of some two hundred sheep's backs is very tiring work; so the judges have struck against rouge, and there is an end of it.

One night, some years ago, an extraordinary thing happened on both lines of downs by the Thames, near Reading, and also along the Chilterns. Most of the flocks over a very large area took a panic and burst from their folds, and next morning thousands of sheep were wandering all over the hills. I feel certain that there must have been an earthquake shock that night. Nothing else could have accounted for such a wide and general stampede. The last authenticated earthquake shock in the South Midlands took place hereabouts in 1775, and was noted at Lord Macclesfield's Castle of Shirbourne, where the water in the moat was seen to rise against the wall of one of the towers. 1

Are our domestic sheep, except for their highly artificial development of wool, really very different from their wild ancestors, the active and flat-coated animals which still feed on the stony mountain-tops? The ways of sheep, not only in this country but abroad, show that a part at least of their wild nature is still strong in them; and if type photographs of all the representative domestic animals of our time, had been possible a few centuries ago, it may be that even in this country the shape of the animal would be found to have been far nearer to the sheep of St. Kilda and of the wild breeds than it is to-day.

In one of the old Cloth Halls of Norfolk are two fine reliefs in plaster, one showing the Argo, bringing the golden fleece, the other a flock of sheep of the day, with a saint in Bishop's mitre and robes preaching to them. The shepherd, in a smock, is spinning wool with a distaff; and the sheep feeding around him, though carefully modelled, are quite unlike any of the modern breeds. Many of the domestic sheep of hot countries are more slender and less woolly than the wild sheep of the mountains. The black-and-white Somali sheep, for instance, are as smooth as a pointer dog.

But it is in temperament and habits that the close connection between the wild and tame breeds is most clearly shown. The excessive domestication of the flocks of Southern England has killed all interest in them even among those who live in the country, and are keen and sympathetic observers of the ways of every other creature in the fields. The beauty of the lambs attracts attention, and the prettiness of the scene when they and their mothers are placed in some sheltered orchard among the wild daffodils and primroses, or in an early meadow by the brook, makes people wonder why they are so stupid when grown up. But the fact is that when not penned up by hurdles and moved from square to square over a whole farm, so that each inch of food may be devoured, each member of the flock can think for itself, and would, in less artificial surroundings, make for itself a creditable name for independence and intelligence. All sheep have retained this distinguishing habit of their ancestors, that they are by nature migratory, and share with nearly all migrant animals a capacity for thought and organisation, and a knowledge of localities. Wild sheep are migratory because they live by preference on the rocky and stony parts of hills just below the snow-line. This is why the tame sheep do so well on the moors of Scotland and mountains of Switzerland. But as the snow-line descends each winter far below their summer feeding haunts, wild sheep either migrate to the lower slopes of the mountains, or, like the deer of the Rockies, move off altogether to great distances. Every winter, for instance, the lower valleys of Yellowstone Park are filled with deer and antelope from the distant mountains. So the tame flocks of Greece, Thrace, Spain, and even Scotland are migratory. In Scotland their transport is modernised, and they travel regularly by steamer from the islands to winter in the Lowlands, and by train from the Highlands. Two years ago a flock of migratory sheep from Ayrshire came for early spring feeding to Hyde Park, and were there shorn, with their Highland collies looking on. In the "old countries" and the non-progressive East of Europe the migration of the flocks is on a vaster and far more romantic scale. In Spain there are some ten millions of migratory sheep, which every year travel as much as two hundred miles from the plains to the "delectable mountains," where the shepherds feed them till the snows descend. These sheep are known as transhumanies and their march, resting places, and behaviour are regulated by ancient and special laws and tribunals dating from the fourteenth century. At certain times no one is allowed to travel on the same route as the sheep, which have a right to graze on all open and common land on the way, and for which a road ninety yards wide must be left on all enclosed and private property. The shepherds lead the flocks, the sheep follow, and the flock is accompanied by mules carrying provisions, and large dogs which act as guards against the wolves. The Merino sheep travel four hundred miles to the mountains, and the total time spent on the migration there and back is fourteen weeks. In Thrace the migration of the flocks is to the northern ranges of Mount Rhodope. The sheep are said to be no less alert than the Pomak shepherds, obeying a signal to assemble at any moment given by the shepherd's horn. The dogs are ferocious in the extreme, as the enemies of sheep in these parts are more commonly men than wild beasts, and the gentle shepherd, who has, since the Russo-Turkish War, exchanged his long gun for a Winchester rifle, shoots at sight and asks no questions.

The more nearly domestic sheep can approach the life of the primitive stock, the more intelligent their way of life becomes. The cleverest sheep live on the hills, and the stupidest on the plains. In Wales, for instance, if a new tenant takes over the flock of an outgoing tenant, the latter is by law allowed a higher price if the flock is one which knows the boundaries and paths on the hills. On the plains of Argentina, as Mr. Hudson tells us, the lambs are born so stupid that they will run after a puff-ball rolling before the wind, mistaking it for their mother.

SOME RESULTS OF WILD-BIRD PROTECTION

Among the happiest results of the modern feeling about birds is the conversion of the whole of the Thames above the tideway into a "protected area." This was not done by an order of the Secretary of State, who, by existing law, would have had to make orders for each bit of the river in different counties, and often, where it divides counties, would have been obliged to deal separately with each bank. The Thames Conservancy used their powers, and summarily put a stop to shooting on the river throughout their whole jurisdiction. The effect of this was not seen all at once; but little by little the waterfowl began to return, the kingfishers to increase, and all the birds along the banks grew tamer. Then the County Councils of Oxfordshire, Buckinghamshire, and Berkshire forbade the killing of owls and kingfishers, and this practically made the river and its banks a sanctuary.

The water-hen are so numerous that at Nuneham Lock they run into the cottages, and at other locks the men complain they eat all their winter cabbages. As many as forty at a time have been counted on the meadows. Mr. Harcourt has also established a wild-duck colony on and about the island at Nuneham. The island has a pond in the centre, with sedges and ancient willows and tall trees round. There the really wild ducks join the home-bred ones in winter. Lower down, the scene on late summer days is almost like a poultry-yard, with waterfowl and wild pigeons substituted for ducks and chickens. Young water-hens of all sizes pipe and flutter in the reeds, and feed on the bank within a few feet of those rowing or fishing, and their only enemies are the cats, which, attracted by their numbers, leave the cottages for the river and stalk them, while the old water-hens in vain try to get their too tame young safe on to the water again.

Though kingfishers have increased fast they are less in evidence, being naturally shy after years of persecution. In summer they keep mainly at the back of the willows, away from the river, so long as the latter is crowded with boats.

It was not till November, 1899, that I saw the kingfishers at play, as I had long hoped to do, in such numbers as to make a real feature on the river. It was a brilliant, warm, sunny morning, such as sometimes comes in early winter, and I went down before breakfast to Clifton Bridge. There the shrill cry of the kingfishers was heard on all sides, and I counted seven, chasing each other over the water, darting in swift flight round and round the pool, and perching on the cam-shedding in a row to rest. Presently two flew up and hovered together, like kestrels, over the stream. One suddenly plunged, came up with a fish, and flying to the other, which was still hovering, put the fish into its beak. After this pretty gift and acceptance both flew to the willows, where, let us hope, they shared their breakfast.

In a row down the river extending over ten miles I saw more than twenty kingfishers, most of them flying out, as is their custom, on the side of the willows and osiers averse from the river, but some being quite content to remain on their perches from which they fish, while the boat slipped down in midstream. As they sit absolutely motionless, and the reddish breast, and not the brilliant back, is turned to the water, it needs quick eyes to see these watchers by the stream.

The total prohibition of shooting on the water or banks is also producing the usual effect on the other birds and beasts. They are rapidly becoming tame, and the oarsman has the singular pleasure of floating down among all kinds of birds which do not regard him as an enemy. Young swallows sit fearlessly on the dead willow boughs to be fed by their parents; the reed-buntings and sedge-warblers scarcely move when the oar dips near the sedge on which they sit; wood-pigeons sit on the margin and drink where the pebble-banks or cattle-ways touch the water; and the water-rats will scarcely stop their business of peeling rushes to eat the pith, even if a boatload of children passes by.

The return of the birds, and especially of wild fowl, to the London river is the result partly of the same causes which have restored the fish to its waters; partly, also, of measures affecting a wider area, but carried out with far less physical difficulty. Their presence is evidence that the tidal Thames now yields them a stock of food so abundant as to tempt birds like the heron, the water-hen, and the kingfisher back to their old haunts. It shows, secondly, that the by-laws for the protection of birds passed by the counties of London, Surrey, and Middlesex, and by the Thames Conservancy (which was the pioneer in this direction by forbidding shooting on the river), are so far effective that the stock is rapidly increasing; and, lastly, that the birds are preserved and left in peace to a great extent on the London river itself. The following are the most marked instances of this return of river fowl which have come under the writer's notice; but in every case there have been preliminary advances on the part of the birds, which show that what is now recorded is only one step further in the general tendency to resume their old habits, or even to go beyond their former limits of place and time in resorting to the river. The herons from Richmond Park have extended their usual nightly fishing ground, which formerly ended at Kew Bridge, four miles further down the river, almost to Hammersmith Bridge, and in place of coming late at night, under cover of darkness, have made a practice of flying down at dusk, and pitching on the edge of Chiswick Eyot. 1 Their regular appearance led to various inquiries as to the nature of the "big birds like geese" which flew down the river and made a noise in the evening, questions which were answered, in one case, by the appearance of one of the birds as it swung round in the air opposite a terrace of houses, and dropped in the stream to fish, not twenty yards from the road. As the heron is naturally among the shyest of all waterside birds, and seeks solitude above all things, these visits show that the quantity of fish in the lower river must be great, and also that the London herons, now never shot at, are losing their inbred dislike of houses and humanity. Their footprints have been found on the mud opposite a creek in Hammersmith, round which is one of the most crowded quarters of the poorer folk of West London. The birds had been fishing within ten yards of the houses, which at this point are largely inhabited by organ-grinders and vendors of ice-creams, callings which do not promote quiet and solitude in the immediate neighbourhood. In the evening and early morning a few wild ducks accompany the herons as low as the reach above Hammersmith Bridge, and single ducks have been seen even at midday flying overhead. At sunrise one Midsummer Day I saw a sheldrake (probably an escaped bird) flying down the river, looking very splendid in its black, white, and red plumage, in the bright light of the morning. It haunted the reach for some days, and was not shot. Among other visitors to this part of the river and its island during spring were a curlew, which fed for some time on the eyot during the early morning, and a pair of pheasants, one of which, an old-fashioned English cock bird, was subsequently captured unhurt. A flock of sandpipers remained there for some weeks, and during the summer numbers of sedge-warblers have nested on and around the eyot; the cuckoo has been a regular visitor to the osier-bed in the early morning, probably with a view to laying its eggs in the sedge-warblers' nests. As a set-off to these early visits of the cuckoo, a nightjar has hunted round the islet for moths, both at dusk and during the night, when its note may often be heard. This is a fairly long list of interesting birds revisiting a portion of the river which the London boundary crosses. At a distance of less than half a mile, on some ornamental water near the river, an even more unexpected increase of the bird population has been noted. A pair of kingfishers nested and reared their brood in an old gravel-pit, while several nests of young dabchicks hatched by the pool. 2 There also during the spring a pair of tufted ducks appeared, and remained for some days before going on their journey to their breeding haunts. One lamentable event in the bird life of the Thames deserves mention. A pair of swans ventured to nest within a few hundred feet of the London boundary. The hen, a very shy young bird, laid three eggs on Chiswick Eyot, and the pair, being supplied with material, diligently built up their nest day by day until it was above the tide level. They sat for five weeks, the cock bird keeping anxious guard day and night, while the hen would probably have died of starvation unless fed by kindly neighbours, for the river affords very little food for a swan, and this required far longer time to find than the bird was willing to spare from her nest. This was then robbed in the night, and the cock bird maltreated in defending it. The return of fish and fowl to the London Thames shows by the best of tests that the efforts of the Thames Conservancy to preserve the amenities of the river, of the Sewage Committee of the County Council to maintain its purity, or rather to render it less impure at its mouth, and of the adjacent County Authorities to protect bird life, are all yielding good results, and justify the courage with which such an apparently hopeless task was undertaken. To the Conservancy I would offer one or two suggestions, which County Councillors might also consider. The river is the only large natural feature still left in the area of London and Greater London. Now that it contains water in place of sewage, there is a guarantee that its main element as a natural amenity in a great city will be maintained, and as it becomes purer, so will the facilities which it offers for boating, fishing, and bathing increase. But it should not be embanked beyond the present limit at Putney. Stone walls are not a thing of beauty, and a natural river-bank is. At present, from Putney to Richmond the greater part of the Thames flows between natural boundaries. If these can be maintained, the growth of willows, sedge, hemlock, reeds, water ranunculus, and many other fine and luxuriant plants affords insect food for the fish and shelter for the birds, besides giving to the river its natural floral border. If this is replaced by stone banks the birds and the fish will move elsewhere.

[1] Mr. J.E. Vincent tells me that in 1902 the herons were heard as far down the river as Chelsea.

OSIERS AND WATER-CRESS

Osiers, the shoots of which are cut yearly for making baskets, crates, lobster-pots, and eel-traps are a form of crop of which not nearly as much is made in the Thames Valley as their profitable return warrants. Properly managed they nearly always pay well, and, in addition, they are very ornamental, and for the whole of the summer, autumn, and winter are one of the very best forms of covert for game. They are commonly seen near rivers, especially in parts where the ground is flooded in winter. But osiers may be grown anywhere on good ground, and are a rapid and paying crop, giving very little trouble, though they need some attention even on the banks of tidal rivers. It is estimated that in the whole of Great Britain there are only between 7,000 and 8,000 acres of osier beds, but these average three tons of rods per acre, and the value of the crop when harvested is often at least £15 per acre gross return. As fruit cultivation is immensely increasing in England, there is a corresponding increase in the demand for baskets to put the fruit in. This is the main reason why osiers, unlike most farm crops, keep up their price. Immense quantities are now imported from Belgium, France, and Germany because our own crop is not nearly sufficient. 1 They do not require a wet soil or to be near water: all that the willow roots need is that the land shall be good and not too dry or sandy. Stagnant, boggy ground does not suit them at all, though they will grow well in light loam. Many species of osier are of most brilliant colouring in winter and early spring. In some the rods are golden yellow; in others the bark is almost scarlet with a bright polish, and the osier bed forms a brilliant object from December to February, just before the rods are cut. The kind of willow grown varies from the slender, tough withes used in making small baskets and eel-traps, to the large, fast-growing rods suited for making crates for heavy goods. The planter must find out for which kind there is the readiest market in the neighbourhood, and then get his land ready. It needs thorough clearing and trenching to the depth of from twenty to thirty inches. The young osiers should then be put in. These should be taken from a nursery in which they have been "schooled" for one year, as in that case they will produce a crop fit to cut one year earlier than if the cuttings have been put at once in the new osier-bed. The cuttings when transferred to the bed should be put in twelve inches apart in the rows, and these rows made at two feet distance from each other. They will need hoeing to keep the ground clear, which will cost £l to £2 per acre for the first two years, and this should be done before the middle of June. When the osiers are well started they grow so densely that they kill out the weeds themselves. The rate of growth even on ordinary field-land is astonishing; they will add eighteen inches in a week. February and March are the months for planting, and March also sees the osier harvest when the time comes to cut them. In the fens the harvesting of the rods begins earlier, but this depends usually on the season, the object being to cut them before the sap begins to rise. Osiers particularly invite the attention of those who are desirous of planting coverts for game. They are a paying crop, and a quick crop, giving cover sooner and of better quality than almost any other form of underwood, and are also very ornamental. It is true that they are cut yearly, but this is not till the shooting season is over. Meantime there is no covert which pheasants like so much as osier-beds, especially if they are near water.

On Chiswick Eyot, which is entirely planted with osiers, there are standing at the time of writing six stacks of bundles set upright. Each stack contains about fifty bundles of the finest rods, nine feet high. Thus the eyot yields at least three hundred bundles. This osier-bed is cut quite early in the year, usually in January, and by February all the fresh rods are planted. Before being peeled the osiers are stood upright in water for a month, and some begin to bud again. This is to make the sap run up, I presume, by which means the bark comes off more readily. I believe that the Chiswick osiers, being of the largest size, are used for making crates, and that they are cut early because there is no need to peel them.

Water-cress growing is an increasing business in the Thames Valley, where the head of every little brook or river in the chalk is used for this purpose. This is good both for business in general and for the fish, for water-cress causes the accumulation of a vast quantity of fish food in various forms.

The artificial culture of water-cress is comparatively modern, and a remarkably pretty side-industry of the country.

Formerly, the cress gatherer was usually a gipsy, or "vagrom man," who wandered up to the springs and by the head waters of brooks at dawn, and took his cresses as the mushroom-gatherer takes mushrooms--by dint of early rising and trespass.

FOG AND DEW PONDS

The cycle of dry seasons seems to be indefinitely prolonged. During the period, now lasting since 1893, in which we have had practically no wet summers, and many very hot ones, a very curious phenomenon has been remarked upon the high and dry chalk downs. The dew ponds, so called because they are believed to be fed by dew and vapours, and not by rain, have kept their water, while the deeper ponds in the valleys have often failed. The shepherds on the downs are careful observers of these ponds, because if they run dry they have to take their sheep to a distance or draw water for them from very deep wells. They maintain that there are on the downs some dew ponds which have never been known to run dry. Others which do run dry do so because the bottom is injured by driving sheep into them and so perforating the bed when the water is shallow, and not from the failure of the invisible means of supply. There seem to be two sources whence these ponds draw water, the dew and the fogs. Summer fogs are very common at night on the high downs, though people who go to bed and get up at normal hours do not know of them. These fogs are so wet that a man riding up on to the hills at 4 a.m. may find his clothes wringing wet, and every tree dripping water, just as during the first week of last November in London many trees distilled pools of water from the fog, as if it had been pouring with rain. Such was the case on July 4th, 1901. The fogs will draw up the hollows towards the ponds, and hang densely round them. Fog and dew may or may not come together; but generally there is a heavy dew deposit on the grass when a fog lies on the hills. After such fogs, though rain may not have fallen for a month, and there is no water channel or spring near the dew pond, the water in it rises prodigiously. Every shepherd knows this, but the actual measurements of this contribution of the vapour-laden air have not often been taken. Yet the subject is an interesting one, and of real importance to all dwellers on high hills, especially those which, like the South Downs, are near the sea, and attract great masses of fog and vapour-laden cloud, but contain few springs on the high rolls of the hills.

The following are some notes of the rise in a dew pond caused by winter fogs on the Berkshire Downs. They were recorded by the Rev. J.G. Cornish at Lockinge, in Berkshire, and taken at his suggestion by a shepherd 1 in a simple and ingenious way. Whenever he thought that a heavy dew or fog was to be expected (and the shepherds are rarely wrong as weather prophets) he notched a stick, and drove it into the pond overnight, so that the notch was level with the surface. Next morning he pulled it up, marked how high the water had risen above the notch, and nicked it again for measurement. On January 18th, after a night of fog, the water rose 1-1/2 in.; on the next day, after another fog, 2 in.; and on January 24th, 1 in. Five nights of winter fog gave a total rise of 8 ins.--a vast weight of water even in a pond of moderate area. Five days of heavy spring dew in April and May, with no fog, gave a total rise in the same pond of 3-1/2 ins., the dews, though one was very heavy, giving less water than the fogs, one of which even in May caused the water to rise 1-1/2 ins. 2 The shepherds say that it is always well to have one or two trees hanging over the pond, for that these distil the water from the fog. This is certainly the case. The drops may be heard raining on to the surface in heavy mists. During the first October mists of 1891 the pavement under certain trees was as wet as if it had been raining, while elsewhere the dust lay like powder. The water was still dripping from these trees at 7 a.m. Under the plane-trees the fallen leaves were as wet from distilled moisture as if they had been dipped in water; yet the ground beyond the spread of the tree was dry. The writer tried a simple experiment in this distilling power of trees. At sundown, two vessels were placed, one under a small cherry-tree in full leaf, the other on some stone flags. Heavy dew was falling and condensing on all vegetation, and on some other objects, with the curious capriciousness which the dewfall seems to show. The leaves of some trees were already wet. In the morning the vessel under the tree, and that in the open, both held a considerable quantity of water, that on the stone caught from dew and condensation, that under the tree mainly from what had dripped from the leaves, which clearly intercepted the direct fall of dew. But the vessel under the tree held just twice as much water as that in the open, the surplus being almost entirely derived from drops precipitated from the leaves. Mr. Sanderson, the manager of the elephant-catching establishment of the Indian Government, noted that in heavy dews in the jungle the water condensed by the leaves could be heard falling like a heavy shower of rain.

Gilbert White, who noticed everything, and lived near a chalk hill, makes some shrewd conjectures, both about the dew ponds and the part which trees play in distilling water from fog, though he does not form the practical conclusion, which we think is a safe one, that the most fog-distilling trees should be discovered and planted to help to supply the water in these air-tapping reservoirs. "To a thinking mind," he writes, "few phenomena are more strange than the state of little ponds on the summits of the chalk hills, many of which are never dry in the most trying droughts of summer. On chalk hills, I say, because in many rocky and gravelly soils springs usually break out pretty high on the sides of elevated grounds and mountains; but no persons acquainted with chalky districts will allow that they ever saw springs in such a soil but in valleys and bottoms, since the waters of so pervious a stratum as chalk all lie on one dead level, as well-diggers have assured me again and again. Now we have many such little round ponds in this district, and one in particular on our sheep-down, three hundred feet above my house, and containing perhaps not more than two or three hundred hogsheads of water; yet it is never known to fail, though it affords drink for three or four hundred sheep, and for at least twenty head of large cattle beside. This pond, it is true, is overhung with two moderate beeches, that doubtless at times afford it much supply. But then we have others as small, which, without the aid of trees, and in spite of evaporation from sun and wind and perpetual consumption by cattle, yet constantly contain a moderate share of water, without overflowing in the winter, as they would do if supplied by springs. By my Journal of May, 1775, it appears that 'the small and even the considerable ponds in the vales are now dried up, but the small ponds on the very tops of the hills are but little affected.' Can this difference be accounted for by evaporation alone, which is certainly more prevalent in the bottoms? Or, rather, have not these elevated pools some unnoticed recruits, which in the night time counterbalance the waste of the day?" These unnoticed recruits, though it is now certain that they come in the form of those swimming vapours from which little moisture seems to fall, are enlisted by means still not certainly known. The common explanation was that the cool surface of the water condensed the dew, just as the surface of a glass of iced water condenses moisture. The ponds are always made artificially in the first instance, and puddled with clay and chalk.

In the notes to a recent edition of "White's Selborne," edited by Professor L.C. Miall, F.R.S., and Mr. W. Warde Fowler, a considerable amount of information on dew ponds is appended to the passage quoted above, but the source of supply still remains obscure. The best dew ponds seem to be on the Sussex Downs, where far more fog and cooling cloud accumulates than on the more inland chalk ranges, because of the nearness of the sea. Near Inkpen Beacon, in Hampshire, there is a dew pond at a height of nine hundred feet, which is never dry, though it waters a large flock of sheep. 3 Dew ponds are often found where there are no other sources of supply, such as the wash coming from a road. Probably if the site for one had to be selected, it should be where the mists gather most thickly and the heaviest dews are shed, local knowledge only possessed by a few shepherds. I have driven up through rain on to the top of the downs, and found there that no rain was falling, but mists lying in the hollows like smoke. Mr. Clement Reid, F.R.S., has added to the "Selborne" notes his own experiences of the best sites for dew ponds. They should, he thinks, be sheltered on the south-west by an overhanging tree. In those he is acquainted with the tree is often only a stunted, ivy-covered thorn or oak, or a bush of holly, or else the southern bank is high enough to give shadow. "When one of these ponds is examined in the middle of a hot summer's day," he adds, "it would appear that the few inches of water in it could only last a week. But in early morning, or towards evening, or whenever a sea-mist drifts in, there is a continuous drip from the smooth leaves of the overhanging tree. There appears also to be a considerable amount of condensation on the surface of the water itself, though the roads may be quite dry and dusty. In fact, whenever there is dew on the grass the pond is receiving moisture."

Though this is evidently the case, no one has explained how it comes about that the pond surface receives so very much more moisture than the grass. The heaviest dew or fog would not deposit an inch, or even two inches, of water over an area of grass equal to that of the pond. None of the current theories of dew deposits quite explain this very interesting question. Two lines of inquiry seem to be suggested, which might be pursued side by side. These are the quantities distilled or condensed on the ponds, and the means by which it is done; and secondly, the kind of tree which, in Gilbert White's phrase, forms the best "alembic" for distilling water from fog at all times of the year. It seems certain that the tree is an important piece of machinery in aid of such ponds, though many remain well supplied without one.

POISONOUS PLANTS

A friend informs me that he has found a quantity of woad growing on the Chilterns above the Thame, enough to stain blue a whole tribe of ancient Britons, and also that on a wall by the roadside between Reading and Pangbourne he discovered several plants of the deadly nightshade, or "dwale." This word is said to be derived from Old French deuil, mourning; but its present form looks very English. The only cases of plant poisoning now common among grown-up people are those caused by mistaking fungi for mushrooms, or by making rash experiments in cooking the former, of which Gerard quaintly says: "Beware of licking honey among the thorns, lest the sweetness of the one do not countervail the sharpness and pricking of the other." But with such a list of toxic plants as our flora can show there is always danger from certain species whose properties are quite unknown to ordinary mortals. Are they equally unknown to the herbalists and that mysterious trade-union of country-women and collectors of herbs by the roadside who deal with them? Probably the trade in poisons not used for serious purposes, but for what used in some parts of England to be called "giving a dose," a punishment for unfaithful, unkind, or drunken husbands, still exists as it did some forty years ago. The collectors of medicinal plants cut from the roadside and rubbish heaps, plants whose "operations" for good are quite well known, and have been handed down by tradition for centuries, cannot be absolutely ignorant of the other side of the picture, the toxic properties which other plants, or sometimes even the same plants, contain. Foxglove, for instance, from which digitalis used as a medicine is extracted, is a good example of these kill-or-cure plants. Every portion of the plant is poisonous, leaves, flowers, stalks, and berries. It affects the heart, and though useful in cases in which the pulsations are abnormal, its symptoms when taken by persons in ordinary health are those of heart failure. Thus foxglove is not only a dangerous but a "subtle" poison.

Among other plants which may cause serious mischief, but are seldom suspected, are such harmless-looking flowers as the meadowsweet, herb-paris, the common fool's-parsley, found growing in quantities in the gardens of unlet houses and neglected ground which has been in cultivation, mezereon, columbine, and laburnum. Meadowsweet has the following set against its name: "A few years since two young men went from London to one of the Southern counties on a holiday excursion, on the last day of which they gathered two very large sheafs of meadowsweet to bring home with them. These they placed in their bedroom at the village inn where they had to put up. In the course of the night they were taken violently ill, and the doctor who was called in stated that they were suffering from the poisonous prussic-acid fumes of the meadowsweet flowers, which he said almost overpowered him when he came into the room. The flowers were at once removed, and the young men, treated with suitable restoratives, were by next morning sufficiently recovered to undertake the journey home." 1 Without knowing what the young men had had for supper, it seems perhaps rather hasty to blame the meadowsweet. But the other flowers mentioned above have a bad record. To take them in order. Herb-paris, which grows in woods and shady places, with four even-sized leaves in a star at the top of the stem, all growing out opposite each other, bears a large, green solitary flower, and a bluish-black berry later. All parts of the plant are poisonous, the berries especially. Fool's-parsley, an unpleasantly smelling, very common plant, which leaves its odour on the hand if the seeds are squeezed or drawn through it, is said to cause numbers of deaths by being mistaken for common parsley and cooked. In the case of poisoning by this plant, it is recommended that milk should be given, the body sponged with vinegar, and mustard poultices put on the sufferer's legs. It is reckoned that one plant produced six thousand and eighty seeds--an unpleasant degree of fecundity for a poisonous weed. Columbine, which is a wild plant with blue or white flowers, as well as a domesticated one, has a toxic principle like that of the monkshood, more especially in the seeds; and the pretty red berries of the mezereon are responsible for the deaths or illness of children nearly every autumn. They are like cherries, and easily picked from the low bushes on which they grow. A dozen are said to be enough to cause death, though this must probably depend on the state of the eater's health. The laburnum, with its golden rain, is potentially a kind of upas tree. The writer has only known of two deaths of children caused by eating the beans in the green pods, but it is said to be a frequent cause of death every year on the Continent, where, possibly, children are less naturally careful about poisonous plants than those in England, to whom risks of this kind are usually and properly made part of the "black list" of the nursery-book of "Don'ts." The seeds will even poison poultry, if they pick them up after they have dropped from the pod. Laburnum is of comparatively recent introduction into Britain, or it would probably earlier have been accorded a place among the severely poisonous plants, dreaded by all.

Of these the deadly nightshade and hemlock are the best known in story, while the yew is most dangerous because far more common. In one case the Rector of a Berkshire village was made very ill by eating honey which had been partly gathered from yew flowers. Green hellebore and monkshood are also classed in the list of the ranker poisons. Deadly nightshade is rather a rare plant, yet it may be seen often enough on the sides of woods where there are old walls. It is poisonous throughout. The flowers are large, single, purple bells, and the berries black and shiny like a black cherry. It is said of this dangerous plant that the roots are computed to be five times more poisonous than the berries, that human beings have been found more susceptible to it than animals, and carnivorous animals more so than others. Children suffer more in proportion to the quantity of poison taken than do adults. But cases of nightshade poisoning are very rare, though two were reported some three years ago. Possibly the berries often fail to ripen, and so are less attractive in appearance. The poisonous hemlocks are two, one of which, the common hemlock, is said to have been the plant from which the Athenians prepared their poison for executing citizens condemned to death; and the other, the water-hemlock, or cowbane, is particularly deadly when eaten by cattle, to which it is fatal in a very few hours. Another plant, used for preparing poison in India, which produces a drug used by some tribes of Thugs for procuring the death of their victims, datura or stramonium, has now found a place amongst our wild flowers. It has an English name, thorn-apple, and is said to have been naturalised by the gipsies, who used the seeds as a medicine and narcotic, and carried them about with them in their wanderings. Like henbane, it is often seen on rubbish-heaps and in old brickfields. The leaf is very handsome, and the flower white and trumpet-shaped. Both this plant and the henbane retain their poisonous properties even when dried in hay, and stalled cows have been known to be poisoned by fodder containing a mixture of the latter plant.

Cattle have a delicate sense of smell which warns them of the danger of most poisonous English herbs, though apparently this warning odour is absent from the plants which kill so many horses when the grass grows on the South African veld, and also from our English yew. Yew was anciently employed as a poison in Europe, much as is the curari to-day in Central America. Dr. W.T. Fernie, the author of "Herbal Simples Approved for Modern Use," says that its juice is a rapidly fatal poison, that it was used for poisoning arrows, and that the symptoms correspond in a very remarkable way with those which follow the bites of venomous snakes. It is believed that in India there is a poison which produces the same effect. An Indian Rajah once desired that a notice should be put in a well-known paper that he did not intend to raise his rents on his accession to the estates. The proprietor of the paper asked him his reasons for wishing for such an advertisement. The Rajah said that his grandfather had raised the rents, and had died of snake-bite; that his father had done the same, and had also died of snake-bite; and that he concluded that there was some connection of cause and effect. The notice was inserted, and this Rajah did not die of snake-bite, or rather of the poison which simulates it.
