Bud's first cast snagged a ground-hugging bush twenty feet behind him. The next time the fly bellied back to float beside the floating line. Then he hooked the only willow growing on the near side of the pool. But all the same Bud was elated. He forgot that the object of this wonderful art was to catch fish and, trying to remember all Gramps had told him, he kept on casting and learning through trial and error. When, after another hour, he was able to make ten successive casts and lay his fly reasonably well, Gramps pronounced judgment,
"Guess we can try now."
Without another word he turned and led the way downstream. Bud followed, knowing that his casting had not won the old man's approval but that Gramps had not wholly disapproved either. Bud did not care or at least he tried not to think about it, for he had discovered another new world. In time, he promised himself grimly, he would be a dry fisherman equal—well, almost equal—to Gramps.
Ten minutes later, Gramps slowed to a turtle's pace. He stole stealthily toward a twenty-foot-wide rock ledge that overhung a deep pool. When he came to the near border of the ledge, he turned and whispered,
"Leave your tackle. We'll crawl the rest of the way."
Bud laid his rod down carefully and, dropping to all fours, crawled beside Gramps toward the water. Five feet from the edge, Gramps dropped to his belly and began to inch toward the pool.
"No fast moves and show no more of yourself than you have to," Gramps whispered.
Bud nodded and wriggled toward the water. He peered down from the ledge and saw a broad, long pool formed by the ledge and fed by rushing riffles that curled around the upstream end of the ledge. On the far side the water was relatively shallow, or perhaps it only looked shallow because there was white sand on the bottom there. Schools of shiners and minnows swam lazily in that part of the pool and the white sand was pock-marked with driftwood that had floated down in flood time and, having become waterlogged, gone to the bottom.
At first glance the water at the near edge of the white sand seemed almost black. This was partly because the white sand ended and partly because the water was deeper there. Actually, it was green-blue, and the high-riding sun bored well into it.
Presently Bud saw a school of fish almost directly beneath him. The fish ranged in length from about five to nearly eighteen inches, and they lay very still in what appeared to be a quiet pocket of water, the biggest fish at the head of the school and the smallest at the end. Farther out, Bud saw more fish. The deepest part of the pool was too deep for the sun to penetrate it, and its invisible depths were tantalizing. Toward the foot of the pool, just before it was gathered in by the riffles that drained it, the trunk of a leaning sycamore jutted out about six feet over the water. The water near the sycamore was sun-sprayed, too. Bud saw flat stones on the bottom away from the bank, but in closer the bottom was in shadow and he could see nothing.
