Like a man half scared to death Pepe waved Ken’s double-barreled gun. Then a yellow head emerged from the water. It was in line with the boat. Ken dared not shoot. “Kill him, George,” yelled Ken. “Tell Pepe to kill him.” George seemed unaccountably silent. But Ken had no time to look for him, for his eyes were riveted on Pepe. The native did not know how to hold a gun properly, let alone aim it. He had, however, sense enough to try. He got the stock under his chin, and, pointing the gun, he evidently tried to fire. But the hammerless did not go off. Then Pepe fumbled at the safety-catch, which he evidently remembered seeing Ken use. The jaguar, swimming with difficulty, perhaps badly wounded, made right for the boat. Pepe was standing on the seat. Awkwardly he aimed. _Boom_! He had pulled both triggers. The recoil knocked him backward. The hammerless fell in the boat, and Pepe’s broad back hit the water; his bare, muscular legs clung to the gunwale, and slipped loose. He had missed the jaguar, for it kept on toward the boat. Still Ken dared not shoot. “George, what on earth is the matter with you?” shouted Ken. Then Ken saw him standing in the brush on the bank, fussing over the crazy .32. Of course at the critical moment something had gone wrong with the old rifle. Pepe’s head bobbed up just on the other side of the boat. The jaguar was scarcely twenty feet distant and now in line with both boat and man. At that instant a heavy swirl in the water toward the middle of the river drew Ken’s attention. He saw the big crocodile, and the great creature did not seem at all lazy at that moment. George began to scream in Spanish. Ken felt his hair stiffen and his face blanch. Pepe, who had been solely occupied with the jaguar, caught George’s meaning and turned to see the peril in his rear. He bawled his familiar appeal to the saints. Then he grasped the gunwale of the boat just as it swung against the branches of the low-leaning tree. He vaulted rather than climbed aboard. Ken forgot that Pepe could understand little English, and he yelled: “Grab an oar, Pepe. Keep the jaguar in the water. Don’t let him in the boat.” But Pepe, even if he had understood, had a better idea. Nimble, he ran over the boat and grasped the branches of the tree just as the jaguar flopped paws and head over the stern gunwale. Ken had only a fleeting instant to get a bead on that yellow body, and before he could be sure of an aim the branch weighted with Pepe sank down to hide both boat and jaguar. The chill of fear for Pepe changed to hot rage at this new difficulty. Then George began to shoot. _Spang_! Ken heard the bullet hit the boat. “George--wait!” shouted Ken. “Don’t shoot holes in the boat. You’ll sink it.” _Spang_! _Spang_! _Spang_! _Spang_!
