Near about the centre, where the land is most level, an unexpected slope goes down into a cuplike depression. This green crater may perhaps have been formed by digging for sand—so long ago that the turf has since grown over smoothly. Standing at the bottom the sides conceal all but the sky overhead. Some few dead leaves of last year, not yet decayed though bleached and brittle, lie here at rest from the winds that swept them over the plain. Silky balls of thistledown come irresolutely rolling over the edge, now this way now that: some rise and float across, some follow the surface and cling awhile to the bennets in the hollow. Pale blue harebells, drooping from their slender stems here and there, meditate with bowed heads, as if full of tender recollections.
Now, on hands and knees (the turf is dry and soft), creep up one side of the bowl-like hollow, where, the thistles make a parapet on the edge, and from behind it look out upon the ground all broken up into low humps, some covered with nettles, others plainly heaps of sand. It is the site of an immense rabbit-burrow, the relic of an old warren which once occupied half the field. The nettle-covered heaps mark old excavations; where the sand shows, there the miners have been recently at work. At the sound of approaching footsteps those inhabitants that had been abroad hastily rushed into their caves, but now (after waiting awhile, and forgetting that the adjacent hollow might hide the enemy) a dozen or more have come forth within easy gunshot. Though a few like this are always looking in and out all through the day, it is not till the approach of evening that they come out in any number.
This is a favourite spot from whence to get a shot at them, but the aim must be deadly, or the rabbit will escape though never so severely wounded. The holes are so numerous that he has never more than a yard to scramble, and as he goes down into the earth his own weight carries him on. If he can but live ten seconds after the lead strikes him, he will generally escape you. Watching patiently (without firing), after the twilight has deepened into night presently you are aware of a longer, larger creature than a rabbit stealing out, seeming to travel close to the earth: it is a badger. There are almost always a couple somewhere about the warren. Their residence is easily discovered because of the huge heap of sand thrown out from the rabbit-hole they have chosen; and it is this ease of discovery that has caused the diminution of their numbers by shot or spade.
The ground sounds hollow underneath the foot—perhaps half an acre is literally bored away under the surface; and you have to thread your way in and out a labyrinth of holes, the earth about some of them perceptibly yielding to your weight. There must be waggon-loads of the sand that has been thrown out. Beyond this central populous quarter suburbs of burrows extend in several directions, and there are detached settlements fifty and a hundred yards away. In ferreting this place the greatest care has to be taken that the ferret is lined with a long string, or so fed that he will not lie in; otherwise, if he is not picked up the moment he appears at the mouth of the hole, he will become so excited at the number of rabbits, and so thirsty for blood, that he will refuse to come forth.
To dig for him is hopeless in that catacomb of tunnels; there is nothing for it but to send a man day after day to watch, and if possible to seize him while passing along the upper ground from one bury to another. In time thirst will drive him to wander; there is no water near this dry, sandy, and rather elevated spot, and blood causes great thirst. Then he will roam across the open, and by-and-by reach the hedges, where in the ditch some water is sure to be found in winter, when ferreting is carried on. So that, if a ferret has been lost some time, it is better to look for him round the adjacent hedges than in the warren.
Long after leaving the bury it is as well to look to your footsteps, because of solitary rabbit-holes hidden by the grass growing up round and even over them. If the foot sinks unexpectedly into one of these, a sprained ankle or even a broken bone may result. Most holes have sand round the mouth, and may therefore be seen even in the dusk; but there are others also used which have no sand at the mouth, the grass growing at the very edge. Those that have sand have been excavated from without, from above; those that have not, have been opened from below. The rabbit has pushed his way up from an old bury, so that the sand he dug fell down behind him into the larger bole.
The same thing may be seen in banks, though then the holes worked from within are not so much concealed by grass. These holes are always very much smaller than the others, some so small that one might doubt how a rabbit could force his body through them. The reason why the other tunnels appear so much larger is because the rabbit has no means of ‘shoring’ up his excavation with planks and timbers, and no ‘cage’ with which to haul up the sand he has moved; so that he must make the mouth wider than is required for the passage of his body, in order to get the stuff out behind him. He can really creep through a much smaller aperture. At night especially, when walking near a bury situate in the open field, beware of putting your foot into one of these holes, which will cause an awkward fall if nothing worse. Some of the older holes, now almost deserted, are, too, so hidden by nettles and coarse grass as to be equally dangerous.
The hereditary attachment of wild animals for certain places is very noticeable at the warren. Though annually ferreted, shot at six months out of the twelve, and trapped—though weasels and foxes prey on the inhabitants—still they cling to the spot. They may be decimated by the end of January, but by September the burrows are as full as ever. Weasels and stoats of course come frequently, bent on murder, but often meet their own doom through over-greediness; for some one generally comes along with a gun once during the day, and if there be any commotion among the rabbits, waits till the weasel or stoat appears at the mouth of a hole, and sends a charge of shot at him. These animals get caught, too, in the gins, and altogether would do better to stay in the hedgerows.
The grass of this great pasture has a different appearance to that in the meadows which are mown for hay. It is closer and less uniformly green, because of the innumerable dead fibres. There are places which look almost white from the bennets which the cattle leave standing to die after the seeds have fallen, and shrink as their sap dries up. Somewhat earlier in the summer, bright yellow strips and patches, like squares of praying-carpet thrown down upon the sward, dotted the slopes: it was the bird’s-foot lotus growing so thickly as to overpower the grass. Mushrooms nestle here and there: those that grow in the open, far from hedge and tree, are small, and the gills of a more delicate salmon colour. Under the elms yonder a much larger variety may be found, which, though edible, are coarser.
Where a part of the lake comes up to the field is a long-disused quarry, whose precipices face the water like a cliff. Thin grasses have grown over the excavations below: the thistles and nettles have covered the heaps of rubbish thrown aside. The steep inaccessible walls of hardened sand are green with minute vegetation. Along the edge above runs a shallow red-brown band—it is the soil which nourishes the roots of the grasses of the field: beneath it comes small detached stones in sand; these fall out, loosened by the weather, and roll down the precipice. Then, still deeper, the sand hardens almost into stone, and finally comes the stone itself; but before the workmen could get out more than a thin layer they reached the level of the water in the lake, which came in on them, slowly forming pools.
