By the bank, fifty yards below Elm Island, stood the Master, looking into water six inches deep. A fern frond, knocked off the bank upstream, came down turning like a little green dragon in the clear water. It passed. Then came an ash-spray, that clung around the pole he leaned on. Its leaves bent to the current, it stayed, it swung away, and drifted on. A dead stick rode after it, and a fly feebly struggling--and then the lovely sight of an otter spreading himself over the stones, moving with the stream, slowly, just touching with his feet, smooth as oil under the water. A twenty-pound dog, thought the Master, remaining quiet by the shallow water, listening to the music of his hounds. There was a stickle below Rothern Bridge. The hounds splashed past him, stooping to the scent. Tarka's head showed, and vanished. He swam under Rothern Bridge, whose three stone arches, bearing heavy motor-transport beyond their old age, showed the cracks of suffering that the ferns were filling green. A sycamore grew out of its lower parapet. Deeper water under the bridge; the frail bubble-chain lay on it. A cry above the bridge; a line of coarser bubbles breaking across the stickle, where six men and two women stood in the river. Tarka's head looked up and saw them. He lay in the deep water. He turned his head, and watched hounds swimming down through the arch. He dived and swam up; was hunted to shallow water again, and returned, making for the stickle. The water was threshed in a line from shillet-bank to shillet-bank, but he did not turn back. As he tried to pass between a man in red and a man in blue, two pole-ends were pushed under his belly in an attempt to hoick him back. But Tarka slipped off the shillet-burnished iron and broke the stickle. The whips ran on the bank, cheering on the hounds. _Get on to 'm! Hark to Deadlock! Leu-on! Leu-on! Leu-on!_ * * * * * A quarter of a mile below Rothern Bridge the river slows into the lower loop of a great S. It deepens until half-way, where the S is cut by the weir holding back the waters of the long Beam Pool. Canal Bridge crosses the river at the top of the S. Where the river begins to slow, at the beginning of the pool, its left bank is bound by the open roots of oak, ash, alder, and sycamore. To hunted otters these trees offered holding as secure as any in the country of the Two Rivers. Harper, the aged hound--he was fourteen years old--knew every holt in the riverside trees of Knackershill Copse, and although he had marked at all of them, only once had he cracked the rib of an otter found in the pool. Leeches infested the unclear water.
