One bunch grew on a bank raised a few inches above the flood which the swollen brook had poured in, and there I walked among them; the leaves came nearly up to the shoulder, the golden flowers on the stalks stood equally high. It was a thicket of iris. Never before had they risen to such a height; it was like the vegetation of tropical swamps, so much was everything drawn up by the continual moisture. Who could have supposed that such a downpour as occurred that summer would have had the effect it had upon flowers? Most would have imagined that the excessive rain would have destroyed them; yet never was there such floral beauty as that year. Meadow-orchis, buttercups, the yellow iris, all the spring flowers came forth in extraordinary profusion. The hay was spoiled, the farmers ruined, but their fields were one broad expanse of flower.
As that spring was one of the wettest, so that of the year in present view was one of the driest, and hence the plantation between the lane and the brook was accessible, the sedges and flags short, and the sedge-birds visible. There is a beech in the plantation standing so near the verge of the stream that its boughs droop over. It has a number of twigs around the stem—as a rule the beech-bole is clear of boughs, but some which are of rather stunted growth are fringed with them. The leaves on the longer boughs above fall off and voyage down the brook, but those on the lesser twigs beneath, and only a little way from the ground, remain on, and rustle, dry and brown, all through the winter.
Under the shelter of these leaves, and close to the trunk, there grew a plant of flag—the tops of the flags almost reached to the leaves—and all the winter through, despite the frosts for which it was remarkable, despite the snow and the bitter winds which followed, this plant remained green and fresh. From this beech in the morning a shadow stretches to a bridge across the brook, and in that shadow my trout used to lie. The bank under the drooping boughs forms a tiny cliff a foot high, covered with moss, and here I once observed shrew mice diving and racing about. But only once, though I frequently passed the spot; it is curious that I did not see them afterwards.
Just below the shadow of the beech there is a sandy, oozy shore, where the footprints of moorhens are often traceable. Many of the trees of the plantation stand in water after heavy rain; their leaves drop into it in autumn, and, being away from the influence of the current, stay and soak, and lie several layers thick. Their edges overlap, red, brown, and pale yellow, with the clear water above and shadows athwart it, and dry white grass at the verge. A horse-chestnut drops its fruit in the dusty road; high above its leaves are tinted with scarlet.
It was at the tail of one of the arches of the bridge over the brook that my favourite trout used to lie. Sometimes the shadow of the beech came as far as his haunts, that was early in the morning, and for the rest of the day the bridge itself cast a shadow. The other parapet faces the south, and looking down from it the bottom of the brook is generally visible, because the light is so strong. At the bottom a green plant may be seen waving to and fro in summer as the current sways it. It is not a weed or flag, but a plant with pale green leaves, and looks as if it had come there by some chance; this is the water-parsnip.
By the shore on this, the sunny side of the bridge, a few forget-me-nots grow in their season, water crow's-foot flowers, flags lie along the surface and slowly swing from side to side like a boat at anchor. The breeze brings a ripple, and the sunlight sparkles on it; the light reflected dances up the piers of the bridge. Those that pass along the road are naturally drawn to this bright parapet where the brook winds brimming full through green meadows. You can see right to the bottom; you can see where the rush of the water has scooped out a deeper channel under the arches, but look as long as you like there are no fish.
The trout I watched so long, and with such pleasure, was always on the other side, at the tail of the arch, waiting for whatever might come through to him. There in perpetual shadow he lay in wait, a little at the side of the arch, scarcely ever varying his position except to dart a yard up under the bridge to seize anything he fancied, and drifting out again to bring up at his anchorage. If people looked over the parapet that side they did not see him; they could not see the bottom there for the shadow, or if the summer noonday cast a strong beam even then it seemed to cover the surface of the water with a film of light which could not be seen through. There are some aspects from which even a picture hung on the wall close at hand cannot be seen. So no one saw the trout; if any one more curious leant over the parapet he was gone in a moment under the arch.
Folk fished in the pond about the verge of which the sedge-birds chattered, and but a few yards distant; but they never looked under the arch on the northern and shadowy side, where the water flowed beside the beech. For three seasons this continued. For three summers I had the pleasure to see the trout day after day whenever I walked that way, and all that time, with fishermen close at hand, he escaped notice, though the place was not preserved. It is wonderful to think how difficult it is to see anything under one's very eyes, and thousands of people walked actually and physically right over the fish.
However, one morning in the third summer, I found a fisherman standing in the road and fishing over the parapet in the shadowy water. But he was fishing at the wrong arch, and only with paste for roach. While the man stood there fishing, along came two navvies; naturally enough they went quietly up to see what the fisherman was doing, and one instantly uttered an exclamation. He had seen the trout. The man who was fishing with paste had stood so still and patient that the trout, re-assured, had come out, and the navvy—trust a navvy to see anything of the kind—caught sight of him.
The navvy knew how to see through water. He told the fisherman, and there was a stir of excitement, a changing of hooks and bait. I could not stay to see the result, but went on, fearing the worst. But he did not succeed; next day the wary trout was there still, and the next, and the next. Either this particular fisherman was not able to come again, or was discouraged; at any rate, he did not try again. The fish escaped, doubtless more wary than ever.
