[SWALLOW-TIME]
The cave-swallows have come at last with the midsummer-time, and the hay and white clover and warm winds that breathe hotly, like one that has been running uphill. With the paler hawkweeds, whose edges are so delicately trimmed and cut and balanced, almost as if made by cleft human fingers to human design, whose globes of down are like geometrical circles built up of facets, instead of by one revolution of the compasses. With foxglove, and dragon-fly, and yellowing wheat; with green cones of fir, and boom of distant thunder, and all things that say, 'It is summer.' Not many of them even now, sometimes only two in the air together, sometimes three or four, and one day eight, the very greatest number—a mere handful, for these cave-swallows at such times should crowd the sky. The white bars across their backs should be seen gliding beside the dark fir copse a quarter of a mile away. They should be seen everywhere, over the house, and to and fro the eaves, where half last year's nest remains; over the meadows and high up in the blue ether. White breasts should gleam in the azure height, appearing and disappearing as they climb or sink, and wheel and slide through those long boomerang-like flights that suddenly take them a hundred yards aside. They should crowd the sky together with the ruddy-throated chimney-swallows, and the great swifts; but though it is hay-time and the apples are set, yet eight eave-swallows is the largest number I have counted in one afternoon. They did not come at all in the spring. After the heavy winter cleared away, the delicate willow-wrens soon sang in the tops of the beautiful green larches, the nightingale came, and the cuckoo, the chimney-swallow, the doves softly cooing as the oaks came into leaf, and the black swifts. Up to May 26 there were no eave-swallows at the Sussex hill-side where these notes were taken; that is more than a month later than the date of their usual arrival, which would be about the middle of April. After this they gradually came back. The chimney-swallows were not so late, but even they are not so numerous as usual. The swifts seem to have come more in their accustomed numbers. Now, the swallows are, of all others, the summer birds. As well suppose the trees without leaves as the summer air without swallows. Ever since of old time the Greeks went round from house to house in spring singing the swallow song, these birds have been looked upon as the friends of man, and almost as the very givers of the sunshine.
The swallow's come, winging
His way to us here;
Fair hours is he bringing,
And a happy new year!
They had a song for everything, the mill song, the reapers' song, just as in Somerset, the apple country, they still have a cider song, or perhaps, rather, an orchard song. Such rhymes might well be chanted about the hay and the wheat, or at the coming of the green leaf, or the yellowing of the acorns, when the cawing of the rooks is incessant, a kind of autumn festival. It seems so natural that the events of the year should be met with a song. But somehow a very hard and unobservant spirit has got abroad into our rural life, and people do not note things as the old folk did. They do not mark the coming of the swallows, nor any of the dates that make the woodland almanack. It is a pity that there should be such indifference—that the harsh ways of the modern town should press so heavily on the country. This summer, too, there seems a marked absence of bees, butterflies, and other insects in the fields. One bee will come along, calling at every head of white clover. By-and-by you may see one more calling at the heathbells, and nothing else, as in each journey they visit only the flower with which they began. Then there will be quite an interval before a third bee is seen, and a fourth may be found dead perhaps on the path, besides which you may not notice any more. For a whole hour you may not observe a humble-bee, and the wasp-like hover-flies, that are generally past all thought of counting, are scarcely seen. A blue butterfly we found in the dust of the road, without the spirit to fly, and lifted him into a field to let him have a chance of life; a few tortoiseshells, and so on—even the white butterflies are quite uncommon, the whites that used to drift along like snowflakes. Where are they all? Did the snow kill them? Is there any connection between the absence of insects and the absence of swallows? If so, how did the swallows know beforehand, without coming, that there were no insects for them? Yet the midsummer hum, the deep humming sound in the atmosphere above, has been loud and persistent over the hayfields, so that there must have been the usual myriads of the insects that cause this sound. While I was thinking in this way a swallow alighted on the turf, picked up a small white moth from among the short grass, and went off with it. In gloomy overcast weather the swallows at the sea-side frequently alight on the pebbles of the beach to pick up the insects which will not rise and fly. Some beaches and sandbanks are much frequented by insects, and black clouds of them sometimes come drifting along, striking the face like small hail.
When swallows fly low, just skimming the ground, it is supposed to be a sign of rain. During the frequent intervals of heavy, overcast weather which have marked this summer, they might have been observed flying low for a week together without a spot of rain falling. Chilly air drives insects downwards, and, indeed, paralyses a great many of them altogether. It is a fall of temperature, and not wet, that makes the swallows chase their prey low down. Insects are not much afraid of rain if it is warm and soft, so that in the midst of showers, if there is sunshine too, you may see the swallows high in the atmosphere. It is when they fly low, but just missing the grass, that their wonderful powers of flight appear. In the air above there are no obstacles, and if you shoot an arrow it travels to the end of its journey without let or hindrance; there are no streets there to turn corners, no narrow lanes, no trees or hedges. When the shallow comes down to the earth his path is no longer that of the immortals, his way is as the way of men, constantly obstructed, and made a thousandfold more difficult by the velocity of his passage. Imagine shooting an arrow from the strongest bow in such a manner that it might travel about seven inches above the ground—how far would it go before it would strike a tall buttercup, a wiry bennet, or stick into a slight rise of the turf? You must imagine it given the power to rise over hedges, to make short angles about buildings, slip between the trunks of trees, to avoid moving objects, as men or animals, not to come in contact with other animated arrows, and by some mysterious instinct to know what is or what is not out of sight on the other side of the wall. I was sitting on a log in the narrowest of narrow lanes, a hedge at the back, in front thick fir trees, whose boughs touched the ground, almost within reach, the lane being nothing more than a broader footpath. It was one of those overcast days when the shelter of the hedge and the furze was pleasant in July. Suddenly a swallow slid by me as it seemed underneath my very hands, so close to the ground that he almost travelled in the rut, the least movement on my part would have stopped him. Almost before I could lift my head he had reached the end of the lane and rose over the gate into the road—not a moments pause before he made that leap over the gate to see if there was a waggon or not in the way; a waggon-load of hay would have blocked the road entirely. How did he know that a man or a horse would not step into his course at the instant he topped the bar?
A swallow never hesitates, never looks before he leaps, threads all day the eyes of needles, and goes on from half-past two in the morning till ten at night, without so much as disturbing a feather. He is the perfection of a machine for falling. His round nest is under the eaves, he throws himself out of window and begins to fall, and keeps on fall, fall, for twenty hours together. His head is bullet-shaped, his neck short, his body all thickened up to the shoulders, tailing out to the merest streak of feather. His form is like a plummet—he is not unlike the heavily weighted minnow used in trolling for pike. Before the bend of the firmly elastic rod, the leaded minnow slides out through the air, running true and sinking without splash into the water. It is proportioned and weighted so that its flight, which is a long fall, may be smooth, and perfectly under control. If wings could be put to the minnow, it would somewhat resemble the swallow. For the swallow is made to fall, and his wings to catch him, and by resisting his descent these outstretched planes lift him again into the sky. He does not fall perpendicularly, the angle of his fall is prolonged and very low, and the swifter he goes the more nearly it approximates to the horizontal. I think he goes swifter when flying just over the ground than when lounging in the easy hammock of the atmosphere. My swallow that came down the lane, in twenty yards opened his wings twenty times and checked his fall, almost grazing the earth, and imperceptibly rose a little, like a flat stone thrown by a boy which suddenly runs up into the air at the end of its flight. He made no blow with his wings; they were simply put out to collect the air in the hollow of their curves, and so prolong his fall. Falling from morn till night, he throws himself on his way, a machine for turning gravity into a motive force. He fits to the circumstances of his flight as water fits to the circumstances of the vessel into which it is poured. No thought, no stop, no rest. If a waggon had been in the way, still he would have got left or right through the very eye of the needle. If a man had been passing, the rush of his wings would not have disturbed the light smoke from his cigar. Farther up the lane there are two gateways opposite without gates. Through these swallows are continually dashing, and I have often felt when coming up the lane as if I must step on them, and half checked myself. I might as well try to step on lightning. A swallow came over the sharp ridge of a slate roof and met a slight current of wind which blew against that side of the shed and rose up it. The bird remained there suspended with outstretched wings, resting on the up-current as if the air had been solid, for some moments. He rode there at anchor in the air. So buoyant is the swallow that it is no more to him to fly than it is to the fish to swim; and, indeed, I think that a trout in a swift mountain stream needs much greater strength to hold himself in the rapid day and night without rest. The friction of the water is constant against him, and he never folds his fins and sleeps. The more I think the more I am convinced that the buoyancy of the air is very far greater than science admits, and under certain conditions it is superior to water as a supporting medium. Swift and mobile as is the swallow's wing, how much swifter and how much more mobile must be his eye! This rapid and ever-changing course is not followed for pleasure as if it were a mazy dance. The whole time as he floats, and glides, and wheels, his eye is intent on insects so small as to be invisible to us at a very short distance. These he gathers in the air, he sees what we cannot see, his eyes are to our eyes as his wings are to our limbs. If still further we were to consider the flow of the nerve force between the eye, the mind, and the wing, we should be face to face with problems which quite upset the ordinary ideas of matter as a solid thing. How is it that dull matter becomes thus inexpressibly sensitive? Is not the swallow's eye a miracle? Then his heart, for he sings as he flies; he makes love and converses, and all as he rushes along—his hopes, his fears, his little store of knowledge, and his wonderful journey by-and-by to Africa. Remember, he carries his life in his wings as we should say in our hands, for if by chance he should strike a solid object, his great speed renders the collision certain death. It stuns him, and if he recovers from that his beak is usually broken so that he must starve. Happily such accidents are rare. The great rapidity of a bird's heart beating so fast seems to render it peculiarly susceptible to death from shock. Great fright will sometimes kill a bird, as for instance, when they have wandered inside a room, and been thoughtlessly held in some one's hand. Without visible injury, the heart, after beating excessively violently, almost as rapidly slows, the nictitating membrane is drawn over the eyes, the head falls to one side, and the bird becomes lifeless from nervous exhaustion. The beautiful swallows, be tender to them, for they symbol all that is best in nature and all that is best in our hearts.
[BUCKHURST PARK.]
An old beech tree had been broken off about five feet from the ground, and becoming hollow within, was filled with the decay of its own substance. In this wood-sorrel had taken root, and flower and leaf covered the space within, white flower and green leaf flourishing on old age. The wood-sorrel leaf, the triune leaf, is perhaps more lovely even than the flower, like a more delicately shaped clover of a tenderer green, and it lasts far on into the autumn. When the violet leaves are no more looked for, when the cowslips have gone, and the bluebells have left nothing behind them but their nodding seed-cases, still the wood-sorrel leaf stays on the mound, in shape and colour the same, and as pleasantly acid to the taste now under the ripening nuts as in May. At its coming it is folded almost like a. green flower; at Midsummer, when you are gathering ferns, you find its trefoil deep under the boughs; it grows, too, in the crevices of the rock over the spring. The whortleberry leaves, that were green as the myrtle when the wood-sorrel was in bloom, have faded somewhat now that their berries are ripening. Another beech has gone over, and lies at full length, a shattered tube, as it were, of timber; for it is so rotten within, and so hollow and bored, it is little else than bark. Others that stand are tubes on end, with rounded knot-holes, loved by the birds, that let air and moisture into the very heart of the wood. They are hardly safe in a strong wind. Others again, very large and much shorter, have sent up four trunks from one root, a little like a banyan, quadruple trees built for centuries, throwing abroad a vast roof of foliage, whose green in the midst of summer is made brown by sacks and sacks of beech nuts. These are the trees to camp by, and that are chosen by painters. The bark of the beech is itself a panel to study, spotted with velvet moss brown-green, made grey with close-grown lichen, stained with its own hues of growth, and toned by time. To these add bright sunlight and leaf shadow, the sudden lowering of tint as a cloud passes, the different aspects of the day and the evening, and the changes of rain and dry weather. You may look at the bark of a beech twenty times and always find it different. After crossing Virgil's Bridge in the deep coombe at the bottom of Marden Hill these great beeches begin, true woodland trees, and somehow more forest-like than the hundreds and hundreds of acres of fir trees that are called forest. There is another spirit among the beech trees; they look like deer and memories of old English life.
The wood cooper follows his trade in a rude shed, splitting poles and making hoops the year through, in warm summer and iron-clad winter. His shed is always pitched at the edge of a great woodland district. Where the road has worn in deeply the roots of the beeches hang over, twisted in and out like a giant matting, a kind of cave under them. Dark yew trees and holly trees stand here and there; a yew is completely barked on one side, stripped clean. If you look close you will see scores in the wood as if made with a great nail. Those who know Exmoor will recognise these signs in a moment; it is a fraying-post where the stags rubbed the velvet from their horns last summer. There are herds of red deer in the park. At one time there were said to be almost as many as run free and wild over the expanse of Exmoor. They mark the trees very much, especially those with the softer bark. Wire fencing has been put round many of the hollies to protect them. A stag occasionally leaps the boundary and forages among the farmers' corn, or visits a garden, and then the owner can form some idea of what must have been the difficulties of agriculture in mediæval days. Deer more than double the interest of a park. A park without deer is like a wall without pictures. However well proportioned the room, something is lacking if the walls be blank. However noble the oaks and wide the sweep of sward, there is something wanting if antlers do not rise above the fern. The pictures that the deer make are moving and alive; they dissolve and re-form in a distant frame of tree and brake. Lately the herd has been somewhat thinned, having become too numerous. One slope is bare of grass, a patch of yellow sand, which if looked at intently from a distance seems presently to be all alive like mites in cheese, so thick are the rabbits in the warren. Under a little house, as it were, built over a stream is a chalybeate fountain with virtues like those of Tunbridge Wells.
