Chapter 8
One spring, hearing a loud chattering in the copse, and recognising the alarm notes of the missel-thrush, I cautiously crept up the hedge, and presently found three crows up in a birch tree, just above where the thrushes were calling. The third crow--probably a descendant of the other two--had joined in a raid upon the missel-thrushes' brood. Both defenders and assailants were in a high state of excitement; the thrushes screeching, and the crows in a row one above the other on a branch, moving up and down it in a restless manner. I fear they had succeeded in their purpose, for no trace of the young birds was visible.
The nest of the missel-thrush is so frequently singled out for attack by crows that it would seem the young birds must possess a peculiar and attractive flavour; or is it because they are large? There are more crows round London than in a whole county, where the absence of manufactures and the rural quiet would seem favourable to bird life. The reason, of course, is that in the country the crows frequenting woods are shot and kept down as much as possible by gamekeepers.
In the immediate environs of London keepers are not about, and even a little farther away the land is held by many small owners, and game preservation is not thought of. The numerous pieces of waste ground, "to let on building lease," the excavated ground, where rubbish can be thrown, the refuse and ash heaps--these are the haunts of the London crow. Suburban railway stations are often haunted by crows, which perch on the telegraph wires close to the back windows of the houses that abut upon the metals. There they sit, grave and undisturbed by the noisy engines which pass beneath them.
In the shrubberies around villa gardens, or in the hedges of the small paddocks attached, thrushes and other birds sometimes build their nests. The children of the household watch the progress of the nest, and note the appearance of the eggs with delight. Their friends of larger growth visit the spot occasionally, and orders are given that the birds shall be protected, the gardeners become gamekeepers, and the lawn or shrubbery is guarded like a preserve. Everything goes well till the young birds are almost ready to quit the nest, when one morning they are missing.
The theft is, perhaps, attributed to the boys of the neighbourhood, but unjustly, unless plain traces of entry are visible. It is either cats or crows. The cats cannot be kept out, not even by a dog, for they watch till his attention is otherwise engaged. Food is not so much the object as the pleasure of destruction, for cats will kill and yet not eat their victim. The crow may not have been seen in the garden, and it may be said that he could not have known of the nest without looking round the place. But the crow is a keen observer, and has not the least necessity to search for the nest.
He merely keeps a watch on the motions of the old birds of the place, and knows at once by their flight being so continually directed to one spot that there their treasure lies. He and his companion may come very early in the morning--summer mornings are bright as noonday long before the earliest gardener is abroad--or they may come in the dusk of the evening. Crows are not so particular in retiring regularly to roost as the rook.
The furze and copse frequented by the pair which I found attacking the missel-thrushes are situate at the edge of extensive arable fields. In these, though not overlooked by the gamekeepers, there is a good deal of game which is preserved by the tenants of the farm. After the bitter winter and wet summer of 1879, there was a complaint, too well founded, that the partridges were diminished in numbers. But the crows were not. There were as many of them as ever. When there were many partridges the loss of a few eggs or chicks was not so important. But when there are but few, every egg or chick destroyed retards the re-stocking of the fields.
The existence of so many crows all round London is, in short, a constant check upon the game. The belt of land immediately outside the houses, and lying between them and the plantations which are preserved, is the crow's reserve, where he hunts in security. He is so safe that he has almost lost all dread of man, and his motions can be observed without trouble. The ash-heap at the corner of the furze, besides the crows, became the resort of rats, whose holes were so thick in the bank as to form quite a bury. After the rats came the weasels.
When the rats were most numerous, before the ash-heap was sifted, there was a weasel there nearly every day, slipping in and out of their holes. In the depth of the country an observer might walk some considerable distance and wait about for hours without seeing a weasel; but here by the side of a busy suburban road there were plenty. Professional ratcatchers ferreted the bank once or twice, and filled their iron cages. With these the dogs kept by dog-fanciers in the adjacent suburb were practised in destroying vermin at so much a rat. Though ferreted and hunted down by the weasels the rats were not rooted out, but remained till the ash-heap was sifted and no fresh refuse deposited.
In one place among the gorse, the willows, birches, and thorn bushes make a thick covert, which is adjacent to several of the hidden pools previously mentioned. Here a brook-sparrow or sedge-reedling takes up his quarters in the spring, and chatters on, day and night, through the summer. Visitors to the opera and playgoers returning in the first hours of the morning from Covent Garden or Drury Lane can scarcely fail to hear him if they pause but one moment to listen to the nightingale.
The latter sings in one bush and the sedge-reedling in another close together. The moment the nightingale ceases the sedge-reedling lifts his voice, which is a very penetrating one, and in the silence of the night may be heard some distance. This bird is credited with imitating the notes of several others, and has been called the English mocking-bird, but I strongly doubt the imitation. Nor, indeed, could I ever trace the supposed resemblance of its song to that of other birds.
It is a song of a particularly monotonous character. It is distinguishable immediately, and if the bird happens to nest near a house, is often disliked on account of the loud iteration. Perhaps those who first gave it the name of the mocking-bird were not well acquainted with the notes of the birds which they fancied it to mock. To mistake it for the nightingale, some of whose tones it is said to imitate, would be like confounding the clash of cymbals with the soft sound of a flute.
Linnets come to the furze, and occasionally magpies, but these latter only in winter. Then, too, golden-crested wrens may be seen searching in the furze bushes, and creeping round and about the thorns and brambles. There is a roadside pond close to the furze, the delight of horses and cattle driven along the dusty way in summer. Along the shelving sandy shore the wagtails run, both the pied and the yellow, but few birds come here to wash; for that purpose they prefer a running stream if it be accessible.
Upon the willow trees which border it, a reed-sparrow or blackheaded bunting may often be observed. One bright March morning, as I came up the road, just as the surface of the pond became visible it presented a scene of dazzling beauty. At that distance only the tops of the ripples were seen, reflecting the light at a very low angle. The result was that the eye saw nothing of the water or the wavelet, but caught only the brilliant glow. Instead of a succession of sparkles there seemed to be a golden liquid floating on the surface as oil floats--a golden liquid two or three inches thick, which flowed before the wind.
Besides this surface of molten gold there was a sheen and flicker above it, as if a spray or vapour, carried along, or the crests of the wavelets blown over, was also of gold. But the metal conveys no idea of the glowing, lustrous light which filled the hollow by the dusty road. It was visible from one spot only, a few steps altering the angle lessened the glory, and as the pond itself came into view there was nothing but a ripple on water somewhat thick with suspended sand. Thus things change their appearance as they are looked at in different ways.
A patch of water crowsfoot grows on the farthest side of the pond, and in early summer sends up lovely white flowers.
HEATHLANDS
Sandown has become one of the most familiar places near the metropolis, but the fir woods at the back of it are perhaps scarcely known to exist by many who visit the fashionable knoll. Though near at hand, they are shut off by the village of Esher; but a mile or two westwards, down the Portsmouth highway, there is a cart road on the left hand which enters at once into the woods.
The fine white sand of the soil is only covered by a thin coating of earth formed from the falling leaves and decayed branches, so thin that it may sometimes be rubbed away by the foot or even the fingers. Grass and moss grow sparingly in the track, but wherever wheels or footsteps have passed at all frequently the sand is exposed in white streaks under the shadowy firs. In grass small objects often escape observation, but on such a bare surface everything becomes visible. Coming to one of these places on a summer day, I saw a stream of insects crossing and recrossing, from the fern upon one side to the fern upon the other.
They were ants, but of a very much larger species than the little red-and-black "emmets" which exist in the meadows. These horse ants were not much less than half an inch in length, with a round spot at each end like beads, or the black top of long pins. The length of their legs enabled them to move much quicker, and they raced to and fro over the path with great rapidity. The space covered by the stream was a foot or more broad, all of which was crowded and darkened by them, and as there was no cessation in the flow of this multitude, their numbers must have been immense.
Standing a short way back, so as not to interfere with their proceedings, I saw two of these insects seize hold of a twig, one at each end. The twig, which was dead and dry, and had dropped from a fir, was not quite so long as a match, but rather thicker. They lifted this stick with ease, and carried it along, exactly as labourers carry a plank. A few short blades of grass being in the way they ran up against them, but stepped aside, and so got by. A cart which had passed a long while since had forced down the sand by the weight of its load, leaving a ridge about three inches high, the side being perpendicular.
Till they came to this cliff the two ants moved parallel, but here one of them went first, and climbed up the bank with its end of the stick, after which the second followed and brought up the other. An inch or two farther, on the level ground, the second ant left hold and went away, and the first laboured on with the twig and dragged it unaided across the rest of the path. Though many other ants stayed and looked at the twig a moment, none of them now offered assistance, as if the chief obstacle had been surmounted.
Several other ants passed, each carrying the slender needles which fall from firs, and which seemed nothing in their powerful grasp. These burdens of wood all went in one direction, to the right of the path.
I took a step there, but stayed to watch two more ants, who had got a long scarlet fly between them, one holding it by the head and the other by the tail. They were hurrying their prey over the dead leaves and decayed sticks which strewed the ground, and dragging it mercilessly through moss and grass. I put the tip of my stick on the victim, but instead of abandoning it they tugged and pulled desperately, as if they would have torn it to pieces rather than have yielded. So soon as I released it away they went through the fragments of branches, rushing the quicker for the delay.
A little farther there was a spot where the ground for a yard or two was covered with small dead brown leaves, last year's, apparently of birch, for some young birch saplings grew close by. One of these leaves suddenly rose up and began to move of itself, as it seemed; an ant had seized it, and holding it by the edge travelled on, so that as the insect was partly hidden under it, the leaf appeared to move alone, now over sticks and now under them. It reminded me of the sight which seemed so wonderful to the early navigators when they came to a country where, as they first thought, the leaves were alive and walked about.
The ant with the leaf went towards a large heap of rubbish under the sapling birches. While watching the innumerable multitude of these insects, whose road here crossed these dead dry leaves, I became conscious of a rustling sound, which at first I attributed to the wind, but seeing that the fern was still, and that the green leaves of a Spanish chestnut opposite did not move, I began to realise that this creeping, rustling noise, distinctly audible, was not caused by any wind, but by the thousands upon thousands of insects passing over the dead leaves and among the grass. Stooping down to listen better, there could be no doubt of it: it was the tramp of this immense army.
The majority still moved in one direction, and I found it led to the heap of rubbish over which they swarmed. This heap was exactly what might have been swept together by half-a-dozen men using long gardeners' brooms, and industriously clearing the ground under the firs of the fragments which had fallen from them. It appeared to be entirely composed of small twigs, fir-needles, dead leaves, and similar things. The highest part rose about level with my chest--say, between four and five feet--the heap was irregularly circular, and not less than three or four yards across, with sides gradually sloping. In the midst stood the sapling birches, their stumps buried in it, the rubbish having been piled up around them.
This heap was, in fact, the enormous nest or hill of a colony of horse ants. The whole of it had been gathered together, leaf by leaf, and twig by twig, just as I had seen the two insects carrying the little stick, and the third the brown leaf above itself. It really seemed some way round the outer circumference of the nest, and while walking round it was necessary to keep brushing off the ants which dropped on the shoulder from the branches of the birches. For they were everywhere; every inch of ground, every bough was covered with them. Even standing near it was needful to kick the feet continually against the black stump of a fir which had been felled to jar them off, and this again brought still more, attracted by the vibration of the ground.
The highest part of the mound was in the shape of a dome, a dome whitened by layers of fir-needles, which was apparently the most recent part and the centre of this year's operations. The mass of the heap, though closely compacted, was fibrous, and a stick could be easily thrust into it, exposing the eggs. No sooner was such an opening made, and the stick withdrawn from the gap, than the ants swarmed into it, falling headlong over upon each other, and filling the bottom with their struggling bodies. Upon leaving the spot, to follow the footpath, I stamped my feet to shake down any stray insects, and then took off my coat and gave it a thorough shaking.
Immense ant-hills are often depicted in the illustrations to tropical travels, but this great pile, which certainly contained more than a cartload, was within a few miles of Hyde Park Corner. From nests like this large quantities of eggs are obtained for feeding the partridges hatched from the eggs collected by mowers and purchased by keepers. Part of the nest being laid bare with any tool, the eggs are hastily taken out in masses and thrown into a sack. Some think that ant's eggs, although so favourite a food, are not always the most advantageous. Birds which have been fed freely on these eggs become fastidious, and do not care for much else, so that if the supply fails they fall off in condition. If there are sufficient eggs to last the season, then a few every day produce the best effect; if not they had better not have a feast followed by a fast.
The sense of having a roof overhead is felt in walking through a forest of firs like this, because the branches are all at the top of the trunks. The stems rise to the same height, and then the dark foliage spreading forms a roof. As they are not very near together the eye can see some distance between them, and as there is hardly any underwood or bushes--nothing higher than the fern--there is a space open and unfilled between the ground and the roof so far above.
A vast hollow extends on every side, nor is it broken by the flitting of birds or the rush of animals among the fern. The sudden note of a wood-pigeon, hoarse and deep, calling from a fir-top, sounds still louder and ruder in the spacious echoing vault beneath, so loud as at first to resemble the baying of a hound. The call ceases, and another of these watch-dogs of the woods takes it up afar off.
There is an opening in the monotonous firs by some rising ground, and the sunshine falls on young Spanish chestnuts and underwood, through which is a little-used footpath. If firs are planted in wildernesses with the view of ultimately covering the barren soil with fertile earth, formed by the decay of vegetable matter, it is, perhaps, open to discussion as to whether the best tree has been chosen. Under firs the ground is generally dry, too dry for decay; the resinous emanations rather tend to preserve anything that falls there.
No underwood or plants and little grass grows under them; these, therefore, which make soil quickest, are prevented from improving the earth. The needles of firs lie for months without decay; they are, too, very slender, and there are few branches to fall. Beneath any other trees (such as the edible chestnut and birch, which seem to grow here), there are the autumn leaves to decay, the twigs and branches which fall off, while grasses and plants flourish, and brambles and underwood grow freely. The earth remains moist, and all these soon cause an increase of the fertility; so that, unless fir-tree timber is very valuable, and I never heard that it was, I would rather plant a waste with any other tree or brushwood, provided, of course, it would grow.
It is a pleasure to explore this little dell by the side of the rising ground, creeping under green boughs which brush the shoulders, after the empty space of the firs. Within there is a pond, where lank horsetails grow thickly, rising from the water. Returning to the rising ground I pursue the path, still under the shadow of the firs. There is no end to them--the vast monotony has no visible limit. The brake fern--it is early in July--has not yet reached its full height, but what that will be is shown by these thick stems which rise smooth and straight, fully three feet to the first frond.
A woodpecker calls, and the gleam of his green and gold is visible for a moment as he hastens away--the first bird, except the wood-pigeons, seen for an hour, yet there are miles of firs around. After a time the ground rises again, the tall firs cease, but are succeeded by younger firs. These are more pleasant because they do not exclude the sky. The sunshine lights the path, and the summer blue extends above. The fern, too, ceases, and the white sand is now concealed by heath, with here and there a dash of colour. Furze chats call, and flit to and fro; the hum of bees is heard once more--there was not one under the vacant shadow; and swallows pass overhead.
At last emerging from the firs the open slope is covered with heath only, but heath growing so thickly that even the narrow footpaths are hidden by the overhanging bushes of it. Some small bushes of furze here and there are dead and dry, but every prickly point appears perfect; when struck with the walking-stick the bush crumbles to pieces. Beneath and amid the heath what seems a species of lichen grows so profusely as to give a grey undertone. In places it supplants the heath, the ground is concealed by lichen only, which crunches under the foot like hoar-frost. Each piece is branched not unlike a stag's antlers; gather a handful and it crumbles to pieces in the fingers, dry and brittle.
A quarry for sand has been dug down some eight or ten feet, so that standing in it nothing else is visible. This steep scarp shows the strata, yellow sand streaked with thin brown layers; at the top it is fringed with heath in full flower, bunches of purple bloom overhanging the edge, and behind this the azure of the sky.
Here, where the ground slopes gradually, it is entirely covered with the purple bells; a sheen and gleam of purple light plays upon it. A fragrance of sweet honey floats up from the flowers where grey hive-bees are busy. Ascending still higher and crossing the summit, the ground almost suddenly falls away in a steep descent, and the entire hillside, seen at a glance, is covered with heath, and heath alone. A bunch at the very edge offers a purple cushion fit for a king; resting here a delicious summer breeze, passing over miles and miles of fields and woods yonder, comes straight from the distant hills. Along those hills the lines of darker green are woods; there are woods to the south, and west, and east, heath around, and in the rear the gaze travels over the tops of the endless firs. But southwards is sweetest; below, beyond the verge of the heath, the corn begins, and waves in the wind. It is the breeze that makes the summer day so lovely.
The eggs of the nighthawk are sometimes found at this season near by. They are laid on the ground, on the barest spots, where there is no herbage. At dusk, the nighthawk wheels with a soft yet quick flight over the ferns and about the trees. Along the hedges bounding the heath butcher-birds watch for their prey--sometimes on the furze, sometimes on a branch of ash. Wood-sage grows plentifully on the banks by the roads; it is a plant somewhat resembling a lowly nettle; the leaves have a hop-like scent, and so bitter and strong is the odour that immediately after smelling them the mouth for a moment feels dry with a sense of thirst.
The angle of a field by the woods on the eastern side of the heath, the entire corner, is blue in July with viper's bugloss. The stalks rise some two feet, and are covered with minute brown dots; they are rough, and the lower part prickly. Blue flowers in pairs, with pink stamens and pink buds, bloom thickly round the top, and as each plant has several stalks, it is very conspicuous where the grass is short.
There are hundreds of these flowers in this corner, and along the edge of the wood; a quarter of an acre is blue with them. So indifferent are people to such things that men working in the same field, and who had pulled up the plant and described its root as like that of a dock, did not know its name. Yet they admired it. "It is an innocent-looking flower," they said, that is, pleasant to look at.
By the roadside I thought I saw something red under the long grass of the mound, and, parting the blades, found half-a-dozen wild strawberries. They were larger than usual, and just ripe. The wild strawberry is a little more acid than the cultivated, and has more flavour than would be supposed from its small size.
