When he was convinced that he had succeeded to some extent in fixing his identity upon them he decided to again take up his exploration. To this end he set out toward the north early one day, and, keeping parallel with the shore, travelled rapidly until almost nightfall.
When the sun rose the next morning he saw that it lay almost directly to his right as he stood upon the beach instead of straight out across the water as heretofore, and so he reasoned that the shore line had trended toward the west. All the second day he continued his rapid course, and when Tarzan of the Apes sought speed, he passed through the middle terrace of the forest with the rapidity of a squirrel.
That night the sun set straight out across the water opposite the land, and then the ape-man guessed at last the truth that he had been suspecting.
Rokoff had set him ashore upon an island.
He might have known it! If there was any plan that would render his position more harrowing he should have known that such would be the one adopted by the Russian, and what could be more terrible than to leave him to a lifetime of suspense upon an uninhabited island?
Rokoff doubtless had sailed directly to the mainland, where it would be a comparatively easy thing for him to find the means of delivering the infant Jack into the hands of the cruel and savage foster-parents, who, as his note had threatened, would have the upbringing of the child.
Tarzan shuddered as he thought of the cruel suffering the little one must endure in such a life, even though he might fall into the hands of individuals whose intentions toward him were of the kindest. The ape-man had had sufficient experience with the lower savages of Africa to know that even there may be found the cruder virtues of charity and humanity; but their lives were at best but a series of terrible privations, dangers, and sufferings.
Then there was the horrid after-fate that awaited the child as he grew to manhood. The horrible practices that would form a part of his life-training would alone be sufficient to bar him forever from association with those of his own race and station in life.
A cannibal! His little boy a savage man-eater! It was too horrible to contemplate.
The filed teeth, the slit nose, the little face painted hideously. Tarzan groaned. Could he but feel the throat of the Russ fiend beneath his steel fingers!
