A place where the bank of the brook has been dug away so as to form a sloping approach to the water, in order that cattle may drink without difficulty, is much visited by birds in summer. Some cartloads of small stones originally thrown down to make a firm floor to the drinking-place have in process of time become worn into sand, which the rain has washed into the water. This has helped to form a more than usually sandy bottom to the water just there. Then a bank of mud, or little eyot in the centre of the stream, thickly overgrown with flags, divides the current in two, and the swiftest section passes by the drinking-place and brings with it more sand washed out from the mud; so that just at the edge there is a floor of fine sand covered with water, which six inches from shore is hardly an inch deep. This is just the bathing-place in which birds delight, and here they come, accordingly, all the summer through, day after day.

Sparrows, starlings, finches (including the beautiful goldfinches), blackbirds, and so on, are constantly to and fro. Often several of different species are bathing together. The wagtails, of course, are there. The wagtail wades into the water and stands there. Sometimes he has the appearance of scraping the bottom with his feet, as if to find food. Blackbirds are especially fond of this spot, and may be seen coming to it from the adjacent hedges. They like water, and frequently feed near it; a blackbird may often be found under the great hawthorn bushes which overhang the stream. Hawks may be seen occasionally following the course of the brook or perched on the trees that grow near; they are doubtless aware of the partiality for water shown by so many birds.

The fish have their own favourite places, as the birds in the hedge, and after leaving the hatch there are none for some distance. Then the brook suddenly curves and forms a loop, returning almost upon itself something like the letter 12. The tongue of land thus enclosed is broad at the top, and but two or three yards across at the bottom. There the current on either side is for ever endeavouring to eat away the narrow neck, and forms two deep pools. Some few piles have been driven in on one side to check the process of disintegration, and a willow tree overhangs the pool there. By lying on the grass and quietly looking over the brink, the roach may be seen swimming in the deeper part, and where it shallows up stream is a perch waiting for what may come down. Where the water runs slowly on account of a little bay, there, in semi-darkness under the banks on the mud, are a few tench.

There are several jacks not far off; but, though they prey on the roach, it is noticeable that, unless driven by some one passing by, they rarely go into these deep holes. The jack lies in shallower water and keeps close to the shore under shelter of the flags, or concealed behind the weeds. It is as if he understood that every now and then the shoal of roach will pass round the curve—going from one pool to the other—when they have to swim through the shallower water. Sometimes a solitary fish will shift quarters like this, and must go by the jack lying in ambush.

At the top of the tongue of land (which is planted with withy) another brook joins the first: this brook is very deep, and all but stagnant. In the quiet back-water here—close to and yet out of the swifter stream—is another haunt of the jack.

If alarmed, he does not swim straight up or down the centre of the current but darts half-a-dozen yards in a slanting direction across the stream and hides under another floating weed. Then, if started afresh, he makes another zigzag, and conceals himself once more. At first he remains till you could touch him, if you tried, with a long stick; but at every remove he grows more suspicious, till at last as you approach he is off immediately.

Jacks lie a great deal in the still deep ponds that open off the brook or are connected with it by a deep ditch; they have been known to find their way up to a pond from the brook through a subterranean pipe which supplied it with water. Those that remain in the ponds are usually much larger than those found in the stream: these are often small—say, a pound to two pounds in weight. In the spawning season, however, they come out from the ponds and go up the brook in pairs or trios. They keep close together side by side—the largest in the centre when there are three. The brook at that time seems full of jacks; and to any one who has been accustomed to stroll along it is surprising where they all come from.

Although the jacks lie in the quiet ponds most of the time, yet some of them travel about a great deal, especially the smaller ones ranging from one to two pounds. These will leap a bay or dam if it interrupts their voyaging down the stream. I have seen a young jack, about a foot long, leap over a bay, and fall three or four feet on to the stony floor below, the stones scarcely covered with water. The jack shot himself perhaps two feet, and fell on his side on the stones; there he lay quietly a minute or so, and then gave a bound up, and, lighting in the current, went down with it. A small jack like this will sometimes go out into the irrigated meadows, following the water-carriers for a long distance.
