Toward mid-afternoon Waldo became aware that he was much weaker from the effects of his battle with Korth than he had supposed. He had lost much blood from his wounds, and the exertion of following the trail at a swift pace had reopened some of the worse ones, so that now, as he ran, he was leaving a little trail of blood behind him.

The discovery made him almost frantic, for it seemed to presage failure. His condition would handicap him in the race after the two along whose track he pursued so that it would be a miracle were he to reach Flatfoot before the brute overtook Nadara.

And if he did overtake him in time—what then? Would he be physically able to cope with the brawny monster? He feared that he would not, but that he kept doggedly to the grueling chase augured well for the new manhood that had been so recently born within him.

On and on he stumbled, until at dusk he slipped and fell exhausted to the earth. Twice he struggled to his feet in an attempt to go on, but he was forced to give in, lying where he was until morning.

Slightly refreshed, he ate of the roots and fruit which abounded in the forest, taking up the chase again, but this time more slowly.

He was now convinced that the way led back along the same trail which he had followed into the country, and when he reached the point at which he had first met Korth on the previous day he cut across the little space which intervened between the cave man's tracks and the point at which he had stood before he went down over the divide into the jungle toward the river and the ford.

A moment later he was rewarded by the sight of Nadara's dainty footprints as well as those of Flatfoot leading away along his old trail. The act had saved him several miles of needless tracking.

All that day he followed as rapidly as his weakened condition would permit, but his best efforts seemed dismally snail-like.

Along the way he bowled over a couple of large rodents, which he ate raw, for he had long since learned the desirability of a meat diet for one undergoing severe physical exertion, and had conquered his natural aversion for the uncooked flesh. He even had come to relish it, though often as he dined thus upon meat a broad grin illumined his countenance at the thought of the horror with which his mother and his Boston friends would view such a hideous performance.

As he continued trailing the two he was at first surprised to discover the fidelity with which Nadara had clung to his old trail, and because of this fact he often was able to save miles at a time by taking cross-cuts where, on his way in, he had made wide detours.
