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.
