Chapter 6

Next morning the August sun shone, and the wood was all a-hum with insects. The wasps were working at the pine boughs high overhead; the bees by dozens were crowding to the bramble flowers; swarming on them, they seemed so delighted; humble-bees went wandering among the ferns in the copse and in the ditches--they sometimes alight on fern--and calling at every purple heath-blossom, at the purple knapweeds, purple thistles, and broad handfuls of yellow-weed flowers. Wasp-like flies barred with yellow suspended themselves in the air between the pine-trunks like hawks hovering, and suddenly shot themselves a yard forward or to one side, as if the rapid vibration of their wings while hovering had accumulated force which drove them as if discharged from a cross-bow. The sun had set all things in motion.

There was a hum under the oak by the hedge, a hum in the pine wood, a humming among the heath and the dry grass which heat had browned. The air was alive and merry with sound, so that the day seemed quite different and twice as pleasant. Three blue butterflies fluttered in one flowery corner, the warmth gave them vigour; two had a silvery edging to their wings, one was brown and blue. The nuts reddening at the tips appeared ripening like apples in the sunshine. This corner is a favourite with wild bees and butterflies; if the sun shines they are sure to be found there at the heath-bloom and tall yellow-weed, and among the dry seeding bennets or grass-stalks. All things, even butterflies, are local in their habits. Far up on the hillside the blue green of the pines beneath shone in the sun--a burnished colour; the high hillside is covered with heath and heather. Where there are open places a small species of gorse, scarcely six inches high, is in bloom, the yellow blossom on the extremity of the stalk.

Some of these gorse plants seemed to have a different flower growing at the side of the stem, instead of at the extremity. These florets were cream-coloured, so that it looked like a new species of gorse. On gathering it to examine the thick-set florets, if was found that a slender runner or creeper had been torn up with it. Like a thread the creeper had wound itself round and round the furze, buried in and hidden by the prickles, and it was this creeper that bore the white or cream-florets. It was tied round as tightly as thread could be, so that the florets seemed to start from the stem, deceiving the eye at first. In some places this parasite plant had grown up the heath and strangled it, so that the tips turned brown and died. The runners extended in every direction across the ground, like those of strawberries. One creeper had climbed up a bennet, or seeding grass-stalk, binding the stalk and a blade of the grass together, and flowering there. On the ground there were patches of grey lichen; many of the pillar-like stems were crowned with a red top. Under a small boulder stone there was an ants' nest. These boulders, or, as they are called locally, "bowlers," were scattered about the heath. Many of the lesser stones were spotted with dark dots of lichen, not unlike a toad.

Thoughtlessly turning over a boulder about nine inches square, lo! there was subject enough for thinking underneath it--a subject that has been thought about many thousand years; for this piece of rock had formed the roof of an ants' nest. The stone had sunk three inches deep into the dry soil of sand and peaty mould, and in the floor of the hole the ants had worked out their excavations, which resembled an outline map. The largest excavation was like England; at the top, or north, they had left a narrow bridge, an eighth of an inch wide, under which to pass into Scotland, and from Scotland again another narrow arch led to the Orkney Islands; these last, however, were dug in the perpendicular side of the hole. In the corners of these excavations tunnels ran deeper into the ground, and the ants immediately began hurrying their treasures, the eggs, down into these cellars. At one angle a tunnel went beneath the heath into further excavations beneath a second boulder stone. Without, a fern grew, and the dead dry stems of heather crossed each other.

This discovery led to the turning over of another boulder stone not far off, and under it there appeared a much more extensive and complete series of galleries, bridges, cellars and tunnels. In these the whole life-history of the ant was exposed at a single glance, as if one had taken off the roofs of a city. One cell contained a dust-like deposit, another a collection resembling the dust, but now elongated and a little greenish; a third treasury, much larger, was piled up with yellowish grains about the size of wheat, each with a black dot on the top, and looking like minute hop-pockets. Besides these, there was a pure white substance in a corridor, which the irritated ants seemed particularly anxious to remove out of sight, and quickly carried away. Among the ants rushing about there were several with wings; one took flight; one was seized by a wingless ant and dragged down into a cellar, as if to prevent its taking wing. A helpless green fly was in the midst, and round the outside galleries there crept a creature like a spider, seeming to try to hide itself. If the nest had been formed under glass, it could not have been more open to view. The stone was carefully replaced.

Below the pine wood on the slope of the hill a plough was already at work, the crop of peas having been harvested. The four horses came up the slope, and at the ridge swept round in a fine curve to go back and open a fresh furrow. As soon as they faced down-hill they paused, well aware of what had to be done, and the ploughman in a manner knocked his plough to pieces, putting it together again the opposite way, that the earth he was about to cut with the share might fall on what he had just turned. With a piece of iron he hammered the edge of the share, to set it, for the hard ground had bent the edge, and it did not cut properly. I said his team looked light; they were not so heavily built as the cart-horses used in many places. No, he said, they did not want heavy horses. "Dese yer thick-boned hosses be more clutter-headed over the clots," as he expressed it, _i.e._ more clumsy or thick-headed over the clods. He preferred comparatively light cart-horses to step well. In the heat of the sun the furze-pods kept popping and bursting open; they are often as full of insects as seeds, which come creeping out. A green and black lady-bird--exactly like a tortoise--flew on to my hand. Again on the heath, and the grasshoppers rose at every step, sometimes three or four springing in as many directions. They were winged, and as soon as they were up spread their vanes and floated forwards. As the force of the original hop decreased, the wind took their wings and turned them aside from the straight course before they fell. Down the dusty road, inches deep in sand, comes a sulphur butterfly, rushing as quick as if hastening to a butterfly-fair. If only rare, how valued he would be! His colour is so evident and visible; he fills the road, being brighter than all, and for the moment is more than the trees and flowers.

Coming so suddenly over the hedge into the road close to me, he startled me as if I had been awakened from a dream--I had been thinking it was August, and woke to find it February--for the sulphur butterfly is the February pleasure. Between the dark storms and wintry rains there is a warm sunny interval of a week in February. Away one goes for a walk, and presently there appears a bright yellow spot among the furze, dancing along like a flower let loose. It is a sulphur butterfly, who thus comes before the earliest chiffchaff--before the watch begins for the first swallow. I call it the February pleasure, as each month has its delight. So associated as this butterfly is with early spring, to see it again after months of leaf and flower--after June and July--with the wheat in shock and the scent of harvest in the land, is startling. The summer, then, is a dream! It is still winter; but no, here are the trees in leaf, the nuts reddening, the hum of bees, and dry summer dust on the high wiry grass. The sulphur butterfly comes twice; there is a second brood; but there are some facts that are always new and surprising, however well known. I may say again, if only rare, how this butterfly would be prized! Along the hedgerow there are several spiders' webs. In the centre they are drawn inwards, forming a funnel, which goes back a few inches into the hedge, and at the bottom of this the spider waits. If you look down the funnel you see his claws at the bottom, ready to run up and seize a fly.

Sitting in the garden after a walk, it is pleasant to watch the eave-swallows feeding their young on the wing. The young bird follows the old one; then they face each other and stay a moment in the air, while the insect food is transferred from beak to beak; with a loud note they part. There was a constant warfare between the eave-swallows and the sparrows frequenting a house where I was staying during the early part of the summer. The sparrows strove their utmost to get possession of the nests the swallows built, and there was no peace between them It is common enough for one or two swallows' nests to be attacked in this way, but here every nest along the eaves was fought for, and the sparrows succeeded in conquering many of them. The driven-out swallows after a while began to build again, and I noticed that more than a pair seemed to work at the same nest. One nest was worked at by four swallows; often all four came together and twittered at it.

NATURE ON THE ROOF

Increased activity on the housetop marks the approach of spring and summer exactly as in the woods and hedges, for the roof has its migrants, its semi-migrants, and its residents. When the first dandelion is opening on a sheltered bank, and the pale-blue field veronica flowers in the waste corner, the whistle of the starling comes from his favourite ledge. Day by day it is heard more and more, till, when the first green spray appears on the hawthorn, he visits the roof continually. Besides the roof-tree and the chimney-pot, he has his own special place, sometimes under an eave, sometimes between two gables; and as I sit writing, I can see a pair who have a ledge which slightly projects from the wall between the eaves and the highest window. This was made by the builder for an ornament; but my two starlings consider it their own particular possession. They alight with a sort of half-scream half-whistle just over the window, flap their wings, and whistle again, run along the ledge to a spot where there is a gable, and with another note, rise up and enter an aperture between the slates and the wall. There their nest will be in a little time, and busy indeed they will be when the young require to be fed, to and fro the fields and the gable the whole day through; the busiest and the most useful of birds, for they destroy thousands upon thousands of insects, and if farmers were wise they would never have one shot, no matter how the thatch was pulled about.

My pair of starlings were frequently at this ledge last autumn, very late in autumn, and I suspect they had a winter brood there. The starling does rear a brood sometimes in the midst of the winter, contrary as that may seem to our general ideas of natural history. They may be called roof-residents, as they visit it all the year round; they nest in the roof, rearing two and sometimes three broods; and use it as their club and place of meeting. Towards July the young starlings and those that have for the time at least finished nesting, flock together, and pass the day in the fields, returning now and then to their old home. These flocks gradually increase; the starling is so prolific that the flocks become immense, till in the latter part of the autumn in southern fields it is common to see a great elm-tree black with them, from the highest bough downwards, and the noise of their chattering can be heard a long distance. They roost in firs or in osier-beds. But in the blackest days of winter, when frost binds the ground hard as iron, the starlings return to the roof almost every day; they do not whistle much, but have a peculiar chuckling whistle at the instant of alighting. In very hard weather, especially snow, the starlings find it difficult to obtain a living, and at such times will come to the premises at the rear, and at farmhouses where cattle are in the yards, search about among them for insects.

The whole history of the starling is interesting, but I must here only mention it as a roof-bird. They are very handsome in their full plumage, which gleams bronze and green among the darker shades; quick in their motions, and full of spirit; loaded to the muzzle with energy, and never still. I hope none of those who are so good as to read what I have written will ever keep a starling in a cage; the cruelty is extreme. As for shooting pigeons at a trap, it is mercy in comparison.

Even before the starling whistles much, the sparrows begin to chirp: in the dead of winter they are silent; but so soon as the warmer winds blow, if only for a day, they begin to chirp. In January this year I used to listen to the sparrows chirping, the starlings whistling, and the chaffinches' "chink, chink" about eight o'clock, or earlier, in the morning: the first two on the roof; the latter, which is not a roof-bird, in some garden shrubs. As the spring advances, the sparrows sing--it is a short song, it is true, but still it is singing--perched at the edge of a sunny wall. There is not a place about the house where they will not build--under the eaves, on the roof, anywhere where there is a projection or shelter, deep in the thatch, under the tiles, in old eave-swallows' nest. The last place I noticed as a favourite one in towns is on the half-bricks left projecting in perpendicular rows at the sides of unfinished houses, Half a dozen nests may be counted at the side of a house on these bricks; and like the starlings, they rear several broods, and some are nesting late in the autumn. By degrees as the summer advances they leave the houses for the corn, and gather in vast flocks, rivalling those of the starlings. At this time they desert the roofs, except those who still have nesting duties. In winter and in the beginning of the new year, they gradually return; migration thus goes on under the eyes of those who care to notice it. In London, some who fed sparrows on the roof found that rooks also came for the crumbs placed out. I sometimes see a sparrow chasing a rook, as if angry, and trying to drive it away over the roofs where I live, the thief does not retaliate, but, like a thief, flees from the scene of his guilt. This is not only in the breeding season, when the rook steals eggs, but in winter. Town residents are apt to despise the sparrow, seeing him always black; but in the country the sparrows are as clean as a pink; and in themselves they are the most animated, clever little creatures.

They are easily tamed. The Parisians are fond of taming them. At a certain hour in the Tuilleries Gardens, you may see a man perfectly surrounded with a crowd of sparrows--some perching on his shoulder; some fluttering in the air immediately before his face; some on the ground like a tribe of followers; and others on the marble seats. He jerks a crumb of bread into the air--a sparrow dexterously seizes it as he would a flying insect; he puts a crumb between his lips--a sparrow takes it out and feeds from his mouth. Meantime they keep up a constant chirping; those that are satisfied still stay by and adjust their feathers. He walks on, giving a little chirp with his mouth, and they follow him along the path--a cloud about his shoulders, and the rest flying from shrub to shrub, perching, and then following again. They are all perfectly clean--a contrast to the London Sparrow. I came across one of these sparrow-tamers by chance, and was much amused at the scene, which, to any one not acquainted with birds, appears marvellous; but it is really as simple as possible, and you can repeat it for yourself if you have patience, for they are so sharp they soon understand you. They seem to play at nest-making before they really begin; taking up straws in their beaks, and carrying them half-way to the roof, then letting the straws float away; and the same with stray feathers, Neither of these, starlings nor sparrows, seem to like the dark. Under the roof, between it and the first ceiling, there is a large open space; if the slates or tiles are kept in good order, very little light enters, and this space is nearly dark in daylight. Even if chinks admit a beam of light, it is not enough; they seldom enter or fly about there, though quite accessible to them. But if the roof is in bad order, and this space light, they enter freely. Though nesting in holes, yet they like light. The swallows could easily go in and make nests upon the beams, but they will not, unless the place is well lit. They do not like darkness in the daytime.

The swallows bring us the sunbeams on their wings from Africa to fill the fields with flowers. From the time of the arrival of the first swallow the flowers take heart; the few and scanty plants that had braved the earlier cold are succeeded by a constantly enlarging list, till the banks and lanes are full of them. The chimney-swallow is usually the forerunner of the three house-swallows; and perhaps no fact in natural history has been so much studied as the migration of these tender birds. The commonest things are always the most interesting. In summer there is no bird so common everywhere as the swallow, and for that reason many overlook it, though they rush to see a "white elephant." But the deepest thinkers have spent hours and hours in considering the problem of the swallow--its migrations, its flight, its habits; great poets have loved it; great artists and art-writers have curiously studied it. The idea that it is necessary to seek the wilderness or the thickest woods for nature is a total mistake; nature it, at home, on the roof, close to every one. Eave-swallows, or house-martins (easily distinguished by the white bar across the tail), build sometimes in the shelter of the porches of old houses.

As you go in or out, the swallows visiting or leaving their nests fly so closely as almost to brush the face. Swallow means porch-bird, and for centuries and centuries their nests have been placed in the closest proximity to man. They might be called man's birds, so attached are they to the human race. I think the greatest ornament a house can have is the nest of an eave-swallow under the eaves--far superior to the most elaborate carving, colouring, or arrangement the architect can devise. There is no ornament like the swallow's nest; the home of a messenger between man and the blue heavens, between us and the sunlight, and all the promise of the sky. The joy of life, the highest and tenderest feelings, thoughts that soar on the swallow's wings, come to the round nest under the roof. Not only to-day, not only the hopes of future years, but all the past dwells there. Year after year the generations and descent of the swallow have been associated with our homes, and all the events of successive lives have taken place under their guardianship. The swallow is the genius of good to a house. Let its nest, then, stay; to me it seems the extremity of barbarism, or rather stupidity, to knock it down. I wish I could induce them to build under the eaves of this house; I would if I could discover some means of communicating with them.

It is a peculiarity of the swallow that you cannot make it afraid of you; just the reverse of other birds. The swallow does not understand being repulsed, but comes back again. Even knocking the nest down will not drive it away, until the stupid process has been repeated several years. The robin must be coaxed; the sparrow is suspicious, and though easy to tame, quick to notice the least alarming movement. The swallow will not be driven away. He has not the slightest fear of man; he flies to his nest close to the window, under the low eave, or on the beams in the out-houses, no matter if you are looking on or not. Bold as the starlings are, they will seldom do this. But in the swallow the instinct of suspicion is reversed, an instinct of confidence occupies its place. In addition to the eave-swallow, to which I have chiefly alluded, and the chimney-swallow, there is the swift, also a roof-bird, and making its nest in the slates of houses in the midst of towns. These three are migrants in the fullest sense, and come to our houses over thousands of miles of land and sea.

Robins frequently visit the roof for insects, especially when it is thatched; so do wrens; and the latter, after they have peered along, have a habit of perching at the extreme angle of a gable, or the extreme edge of a corner, and uttering their song. Finches occasionally fly up to the roofs of country-houses if shrubberies are near, also in pursuit of insects; but they are not truly roof-birds. Wagtails perch on roofs; they often have their nests in the ivy, or creepers trained against walls; they are quite at borne, and are frequently seen on the ridges of farmhouses. Tits of several species, particularly the great titmouse and the blue tit, come to thatch for insects, both in summer and winter. In some districts where they are common, it is not unusual to see a goatsucker or fern-owl hawk along close to the eaves in the dusk of the evening for moths. The white owl is a roof-bird (though not often of the house), building inside the roof, and sitting there all day in some shaded corner. They do sometimes take up their residence in the roofs of outhouses attached to dwellings, but not often nowadays, though still residing in the roofs of old castles. Jackdaws, again, are roof-birds, building in the roofs of towers. Bats live in roofs, and hang there wrapped up in their membranous wings till the evening calls them forth. They are residents in the full sense, remaining all the year round, though principally seen in the warmer months; but they are there in the colder, hidden away, and if the temperature rises, will venture out and hawk to and fro in the midst of the winter. Tame pigeons and doves hardly come into this paper, but still it is their habit to use roofs as tree-tops. Rats and mice creep through the crevices of roofs, and in old country-houses hold a sort of nightly carnival, racing to and fro under the roof. Weasels sometimes follow them indoors and up to their roof strongholds.

When the first warm days of spring sunshine strike against the southern side of the chimney, sparrows perch there and enjoy it; and again in autumn, when the general warmth of the atmosphere is declining, they still find a little pleasant heat there. They make use of the radiation of heat, as the gardener does who trains his fruit-trees to a wall. Before the autumn has thinned the leaves, the swallows gather on the highest ridge of the roof in a row and twitter to each other; they know the time is approaching when they must depart for another climate. In winter, many birds seek the thatched roofs to roost. Wrens, tits, and even blackbirds roost in the holes left by sparrows or starlings.
