Just as Pepe came into camp staggering under a load of wood, a flock of russet-colored ducks swung round the bend. They alighted near the shore at a point opposite the camp. The way George and Hal made headers into the pile of luggage for their guns gave Ken an inkling of what he might expect from these lads. He groaned, and then he laughed. George came up out of the luggage first, and he had a .22-caliber rifle, which he quickly loaded and fired into the flock. He crippled one; the others flew up-stream. Then George began to waste shells trying to kill the crippled duck. Hal got into action with his .22. They bounced bullets off the water all around the duck, but they could not hit it. Pepe grew as excited as the boys, and he jumped into the boat and with a long stick began to pole out into the stream. Ken had to caution George and Hal to lower their guns and not shoot Pepe. Below camp and just under the bridge the water ran into a shallow rift. The duck got onto the current and went round the bend, with Pepe poling in pursuit and George and Hal yelling along the shore. When they returned a little later, they had the duck, which was of an unknown species to Ken. Pepe had fallen overboard; George was wet to his knees; and, though Hal did not show any marks of undue exertion, his eyes would have enlightened any beholder. The fact was that they were glowing with the excitement of the chase. It amused Ken. He felt that he had to try to stifle his own enthusiasm. There had to be one old head in the party. But if he did have qualms over the possibilities of the boys to worry him with their probable escapades, he still felt happy at their boundless life and spirit. It was about the middle of the afternoon, and the heat had become intense. Ken realized it doubly when he saw Pepe favoring the shade. George and Hal were hot, but they appeared to be too supremely satisfied with their surroundings to care about that. During this hot spell, which lasted from three o’clock until five, there was a quiet and a lack of life around camp that surprised Ken. It was slumberland; even the insects seemed drowsy. Not a duck and scarcely a bird passed by. Ken heard the mourning of turtle-doves, and was at once struck with the singular deep, full tone. Several trains crossed the bridge, and at intervals the engine at the pumping-tank puffed and chugged. From time to time a native walked out upon the bridge to stare long and curiously at the camp. When the sun set behind the mountain a hard breeze swept down the river. Ken did not know what to make of it, and at first thought there was going to be a storm. Pepe explained that the wind blew that way every day after sunset. For a while it tossed the willows, and waved the Spaniard’s-beard upon the cypresses. Then as suddenly as it had come it died away, taking the heat with it. Whereupon the boys began to get supper. “George, do you know anything about this water?” asked Ken. “Is it safe?”
