The time passed pleasantly to Stephen as he reclined on a heap of skins and blankets watching the forests that bordered the stream, or looking up through the overhanging canopy at the birds and monkeys, the latter of which afforded him great amusement by the way in which they chattered and gesticulated. The mothers with the little ones climbed to the top of the trees, while the males came boldly out on the lower branches to bid defiance to those in the boat. Often he slept, for the heat, and the almost noiseless fall of the paddles, and the tranquil easy motion of the canoe made him exceptionally drowsy. One day his eye fell upon something on a large branch of a tree that bent down to within twelve feet of the water. It was only some ten yards ahead when he noticed it. It was partly hidden by foliage, and for a moment it seemed to him to be a thickening of the branch. He would have passed it without a thought had it not been for a slight movement; then a glance showed him that it was an animal of some kind lying almost flattened upon the tree. He caught up his rifle just as it rose to a crouching attitude, and was upon the point of springing upon Pita. The gun was loaded with shot only, but as he threw up the muzzle and fired almost instantly, the beast gave a terrible roar. Its spring was arrested, and it fell headlong into the water within a foot of the side of the boat. A tawny head, with two rows of big white teeth, arose from the water almost abreast of him, and a great paw was raised to strike at the boat, but Hurka’s rifle cracked out, and the animal sank again below the water. “You have saved my life, señor,” Pita said gravely. “It was a jaguar, and had you not fired it would have struck me down and crushed in my skull with a blow of its paw. I wonder I did not see it, but I was thinking at the time that we had best tie up for an hour or two so as to pass the next village, which is a large one, after dark.” “It was almost hidden among those leaves,” Stephen said, “and had it not moved I should not have noticed it.” [Illustration: “THE ANIMAL WAS ON THE POINT OF SPRINGING WHEN STEPHEN FIRED.”] “I think you blinded it, señor,” Hurka said. “I saw it rise to spring, and snatched at my rifle just as you fired. I think the charge struck it between the eyes, for I saw a sort of blur there just as it fell. I should have been too late; for though I might have hit it as it was in the air, it would assuredly have come down on Pita. “It was not like you, Pita. This comes of thinking while you are paddling instead of keeping your eyes on everything.” “I was wrong,” the Indian replied. “I should have known that an attack by a jaguar was always possible; but this is the first that we have seen since starting, and I had no thought of danger in my mind. I will be more careful in the future. It must have been well hidden, for you did not see it yourself, Hurka, until it moved for its spring.”
