Deeper and deeper into the forest, which grew more and more dense, till, breaking away from its level, it suddenly began to descend in a stiff slope, which rose as steeply fifty yards farther on, forming in all a wandering, tangled little valley, at the bottom of which trickled and gurgled a tiny river some few yards wide, flashing brightly in places where the sun passed through the overhanging trees, but for the most part darkly hidden, and only to be approached with some little difficulty and at the risk of being caught and held by one of the briars' hundred hands. The valley was very beautiful, gloriously attractive, and evidently a very sanctuary for blackbirds, one of which every now and then darted out in full velvet plumage, skimmed a few yards, and then dived out of sight again. They were too common objects to take the boy's attention as he cautiously made his way towards the edge of the little river, but he did stop for a minute as a loud _yuk_, _yuk_, _yuk_, rang out, and a good-sized bird made a streak of green, and, once well in the sunshine, of brilliant scarlet, as it flew over the bushes and amongst the trees in a series of wave-like curves before it disappeared. "That's the greenest woodpecker and the reddest head I have seen this season," said the boy thoughtfully. "That's a fine old cock-bird, and no mistake. Well, green woodpeckers aren't trout, and he wouldn't take my fly if I dropped it near him, and I don't want him to. Now, then, what do you say to a try here?" The lad asked himself the question, and responded by going on cautiously for about a dozen yards through about the most unsuitable pieces of woodland possible for a fly-fisher to try his craft. But Waller Froy, only son of the Squire of Brackendene, was not going to wield a twelve-foot fly-rod, tapering and lissom, and suitable for sending a delicate line floating through the air to drop its lure lightly on the surface of the water. Such practices would have been utterly impossible on any part of the woodland rivulet. But, all the same, he knew perfectly well what he was about, and how to catch the large, fat, dark-coloured, speckled beauties that haunted the stream-- the only way, in fact, unless he had descended to the poacher-like practice of "tickling," and that he scorned. Waller's way was to proceed cautiously through the undergrowth without stirring bough or leaf till he came to some opening on the bank where he could see the dark, slowly gliding stream, or perhaps eddy, through the overhanging boughs.
