Ken took advantage of this tranquil stretch of river to work on his map. He realized that he must use every spare moment and put down his drawings and notes as often as time and travel permitted. It had dawned on Ken that rapids and snakes, and all the dangers along the river, made his task of observation and study one apt to be put into eclipse at times. Once or twice he landed on shore to climb a bluff, and was pleased each time to see that he had lined a comparatively true course on his map. He had doubts of its absolute accuracy, yet he could not help having pride in his work. So far so good, he thought, and hoped for good-fortune farther down the river. *XII* *CATCHING STRANGE FISH* Beyond a bend in the river the boys came upon an island with a narrow, shaded channel on one side, a wide shoal on the other, and a group of huge cypresses at the up-stream end. “Looks good to me,” said Hal. The instant Ken saw the island he knew it was the place he had long been seeking to make a permanent camp for a few days. They landed, to find an ideal camping site. The ground under the cypresses was flat, dry, and covered with short grass. Not a ray of sunlight penetrated the foliage. A pile of driftwood had lodged against one of the trees, and this made easy the question of fire-wood. “Great!” exclaimed Ken. “Come on, let’s look over the ground.” The island was about two hundred yards long, and the lower end was hidden by a growth of willows. Bursting through this, the boys saw a weedy flat leading into a wide, shallow back-eddy. Great numbers of ducks were sporting and feeding. The stones of the rocky shore were lined with sleeping ducks. Herons of all colors and sizes waded about, or slept on one leg. Snipe ran everywhere. There was a great squawking and flapping of wings. But at least half the number of waterfowl were too tame or too lazy to fly. Ken returned to camp with his comrades, all highly elated over the prospects. The best feature about this beautiful island was the absence of ticks and snakes. “Boys, this is the place,” said Ken. “We’ll hang up here for a while. Maybe we won’t strike another such nice place to stay.” So they unloaded the boat, taking everything out, and proceeded to pitch a camp that was a delight. They were all loud in expressions of satisfaction. Then Pepe set about leisurely peeling potatoes; George took his gun and slipped off toward the lower end of the island; Hal made a pen for his racoon, and then more pens, as if he meant to capture a menagerie; and Ken made a comfortable lounging-bed under a cypress. He wanted to forget that nagging worry as to farther descent of the river, and to enjoy this place. “Bang!” went George’s sixteen-gage. A loud whirring of wings followed, and the air was full of ducks. “Never touched one!” yelled Hal, in taunting voice.
