We wandered on in the valley wood, going from bush to bush, little heeding whither we went. There are no woods so silent as the nut-tree; there is scarce a sound in them at that time except the occasional rustle of a rabbit, and the “thump, thump” they sometimes make underground in their buries after a sudden fright. So that the keen plaintive whistle of a kingfisher was almost startling. But we soon found the stream in the hollow. Broader than a brook and yet not quite a river, it flowed swift and clear, so that every flint at the bottom was visible. The nut-tree bushes came down to the edge: the ground was too firm for much rush or sedge; the streams that come out of the chalk are not so thickly fringed with vegetation as others. Some little way along there was a rounded sarsen boulder not far from shore, whose brown top was so nearly on a level with the surface that at one moment the water just covered it, and the next left it exposed. By it we spied a trout; but the hill above gave “Velvet” the command of the hollow; and it was too risky even to think of. After that the nuts were tame; there was nothing left but to turn homewards. As for trout-fishing, there is nothing so easy. Take the top joint off the rod, and put the wire on the second, which is stronger, fill the basket, and replace the fly. There were fellows who used to paddle in canoes up a certain river (not this little stream), pick out the largest trout, and shoot them with pistols, under pretence of practising at water-rats. CHAPTER V WOODLAND TWILIGHT: TRAITORS ON THE GIBBET In a hedge that joined a wood, and about a hundred yards from it, there was a pleasant hiding-place beside a pollard ash. The bank was hollow with rabbit-buries: the summer heat had hardened the clay of the mound and caused it to crack and crumble wherever their excavations left a precipitous edge. Some way up the trunk of the tree an immense flat fungus projected, roughly resembling the protruding lip of a savage enlarged by the insertion of a piece of wood. It formed a black ledge standing out seven or eight inches, two or three inches thick, and extending for a foot or more round the bark. The pollard, indeed, was dead inside, and near the ground the black touch-wood showed. Ash timber must become rarer year by year: for, being so useful, it is constantly cut down, while few new saplings are planted or encouraged to become trees.
