The leg which had been held within the jaws of the crocodile was badly lacerated, but the bone had not been broken, nor were the muscles or tendons sufficiently injured to render it useless. It gave him excruciating pain, that was all.

But Tarzan of the Apes was accustomed to pain, and gave it no further thought when he found that the use of his legs was not greatly impaired by the sharp teeth of the monster.

Rapidly he crawled and swam through the passage which inclined downward and finally upward to open at last into the river bottom but a few feet from the shore line. As the ape-man reached the surface he saw the heads of two great crocodiles but a short distance from him. They were making rapidly in his direction, and with a superhuman effort the man struck out for the overhanging branches of a near-by tree.

Nor was he a moment too soon, for scarcely had he drawn himself to the safety of the limb than two gaping mouths snapped venomously below him. For a few minutes Tarzan rested in the tree that had proved the means of his salvation. His eyes scanned the river as far down-stream as the tortuous channel would permit, but there was no sign of the Russian or his dugout.

When he had rested and bound up his wounded leg he started on in pursuit of the drifting canoe. He found himself upon the opposite of the river to that at which he had entered the stream, but as his quarry was upon the bosom of the water it made little difference to the ape-man upon which side he took up the pursuit.

To his intense chagrin he soon found that his leg was more badly injured than he had thought, and that its condition seriously impeded his progress. It was only with the greatest difficulty that he could proceed faster than a walk upon the ground, and in the trees he discovered that it not only impeded his progress, but rendered travelling distinctly dangerous.

From the old negress, Tambudza, Tarzan had gathered a suggestion that now filled his mind with doubts and misgivings. When the old woman had told him of the child’s death she had also added that the white woman, though grief-stricken, had confided to her that the baby was not hers.

Tarzan could see no reason for believing that Jane could have found it advisable to deny her identity or that of the child; the only explanation that he could put upon the matter was that, after all, the white woman who had accompanied his son and the Swede into the jungle fastness of the interior had not been Jane at all.

The more he gave thought to the problem, the more firmly convinced he became that his son was dead and his wife still safe in London, and in ignorance of the terrible fate that had overtaken her first-born.

After all, then, his interpretation of Rokoff’s sinister taunt had been erroneous, and he had been bearing the burden of a double apprehension needlessly—at least so thought the ape-man. From this belief he garnered some slight surcease from the numbing grief that the death of his little son had thrust upon him.
