Fred Ashman was standing near the edge of the Xingu, as will be remembered, when his attention was diverted for the moment by a puma, which came out of the wood, drank from the stream, and then, after a brief pause, returned to his shelter.

All this while, the dull roar of the rapids was in the explorer's ears, and he was eager to withdraw his attention from the beast and direct it upon the opposite shore, where he was convinced something unusual was going on.

The minute the beast disappeared, he looked across at the point that had so interested him.

The question which he had asked himself some time before, was answered by the sight of a small canoe that was stealing down the river, instead of heading directly across to where he was standing. In this boat was a single individual, using a paddle with the deftness of an American Indian.

Here was something that needed attention, and, with the aid of the brilliant moonlight. Ashman watched the craft and its occupant as closely as if his own fate were wrapped up in its movements—a supposition which it was not improbable was fact itself.

The savage moved slowly, as if sensible of the call for the utmost care, went only a few rods down stream, when he turned out in the water and aimed for the shore where the watcher was standing. He had gone some distance below, and it was to be supposed that the force of the current would carry him still farther, so that if he made a landing it was likely to be far below.

But he who held the paddle was a master of that species of navigation, and Ashman was surprised to observe that he was aiming at the very spot where he was standing carefully concealed in the shadow. If nothing interfered, they were sure of making a closer acquaintance.

The boat was about the middle of the river, when the white man was struck by the immense size of the occupant. He was one of the largest men he had ever seen, his weight sinking the canoe almost to its gunwales.

"He must be the savage who hurled his javelin through our boat," was the conclusion of the astonished Fred. "What a magnificent fellow he is!"

The native sat so that his face was turned toward the young man, who studied his countenance with the deepest interest.

He had the busy head, the large protruding eyes, and the dark, naked skin of all his people. His enormous arms swung the paddle first on one side of the boat and then on the other. As he did so, Fred saw the play of the splendid muscle, which was like that of Hercules himself. Rash would be that antagonist who engaged him in a hand-to-hand struggle.

Nothing in the world was easier than for the explorer to extinguish the life in that impressive specimen of physical manhood, without the least risk to himself, and yet, although he knew him to be the most formidable enemy of his people, he held no thought of doing him harm—at least not at the present stage of his extraordinary business.

It was at this decidedly interesting juncture that a new element obtruded itself. The sounds of guns, shouts and yells, in the direction of the rapids left no doubt that his friends there were having a lively time with the natives.

Ashman would have turned and made all haste thither, but for the presence of this burly giant in front. Whatever was going on down stream was with the full knowledge of him, and he was the one for the white man to look after.

Had the latter been surprised by the sounds of conflict, he would have ceased paddling or headed his boat up stream, but he merely glanced toward the rapids, and continued dipping his paddle and propelling his craft, as if it was his intention to step ashore and grasp the hand of the astonished youth awaiting his arrival.

The passage occupied but a very few minutes. Just before the bank was reached, he made one powerful sweep of the oar, which sent the prow far up the shingle, and then leaped as lightly as a cat from the structure, which bounded up as if relieved of several hundred pounds' weight.

Turning about, the giant stooped down and took a spear as long and heavy as the one he had hurled nearly across the Xingu, through the boat of the explorers.

It seemed that there was to be no end to the obtrusion of "side issues" upon the little drama going on under Fred Ashman's eyes. It must have been that the puma which had slaked its thirst at the Xingu's margin a short time before, had become convinced that parties were near, entitled to his attention.

While endeavoring to locate him, he probably caught sight of the approaching native and concluded that he was the individual to whom he should turn.

Be that as it may, the native had only time to pick up his ponderous spear and face toward the wood, when the lion emerged from the broadening band of shadow, and, with a low, threatening growl, advanced upon him.

Like the cat species to which he belonged, he crouched so low while walking, that his shoulders protruded above his back in large humps, and his belly almost touched the ground. His long tail flirted angrily from side to side, his jaws were parted, disclosing his sharp, carnivorous teeth and blood-red tongue, while his eyes emitted a phosphorescent glow that was like fire itself.
