Gordon King was a young American who had recently graduated in medicine. Having an independent income, he had no need to practise his profession; and well realising, as he did, that there are already too many poor doctors in the world, he had decided to devote himself for a number of years to the study of strange maladies. For the moment he had permitted himself to be lured from his hobby by the intriguing mysteries of the Khmer ruins of Angkor—ruins that had worked so mightily upon his imagination that it had been impossible for him to withstand the temptation of some independent exploration on his own account. What he expected to discover he did not know; perhaps the ruins of a city more mighty than Angkor Thom; perhaps a temple of greater magnificence and grandeur than Angkor Vat; perhaps nothing more than a day's adventure. Youth is like that.
The jungle that had at first appeared so silent seemed to awaken at the footfall of the trespasser; scolding birds fluttered above him, and there were monkeys now that seemed to have come from nowhere. They, too, scolded as they hurtled through the lower terraces of the forest.
He found the going more difficult than he had imagined, for the floor of the jungle was far from level. There were gulleys and ravines to be crossed and fallen trees across the way, and always he must be careful to move as nearly north as was physically possible, else he might come out far from his Cambodian guide when he sought to return. His rifle grew hotter and heavier; his canteen of water insisted with the perversity of inanimate objects in sliding around in front and bumping him on the belly. He reeked with sweat, and yet he knew that he could not have come more than a few miles from the point where he had left his guide. The tall grasses bothered him most, for he could not see what they hid; and when a cobra slid from beneath his feet and glided away, he realised more fully the menace of the grasses, which in places grew so high that they brushed his face.
At the end of two hours King was perfectly well assured that he was a fool to go on, but there was a certain proportion of bulldog stubbornness in his make-up that would not permit him to turn back so soon. He paused and drank from his canteen. The water was warm and had an unpleasant taste. The best that might be said of it was that it was wet. To his right and a little ahead sounded a sudden crash in the jungle. Startled, he cocked his rifle and stood listening. Perhaps a dead tree had fallen, he thought, or the noise might have been caused by a wild elephant. It was not a ghostly noise at all, and yet it had a strange effect upon his nerves, which, to his disgust, he suddenly realised were on edge. Had he permitted the silly folk tale of the Cambodian to so work upon his imagination that he translated into a suggestion of impending danger every unexpected interruption of the vast silence of the jungle?
Wiping the sweat from his face, he continued on his way, keeping as nearly a northerly direction as was possible. The air was filled with strange odours, among which was one more insistent than the others—a pungent, disagreeable odour that he found strangely familiar and yet could not immediately identify. Lazy air currents, moving sluggishly through the jungle, occasionally brought this odour to his nostrils, sometimes bearing but a vague suggestion of it and again with a strength that was almost sickening; and then suddenly the odour stimulated a memory cell that identified it. He saw himself standing on the concrete floor of a large building, the sides of which were lined with heavily barred cages in which lions and tigers paced nervously to and fro or sprawled in melancholy meditation of their lost freedom; and in his nostrils was the same odour that impinged upon them now. However, it is one thing to contemplate tigers from the safe side of iron bars, and it is quite another thing suddenly to realise their near presence unrestrained by bars of any sort. It occurred to him now that he had not previously considered tigers as anything more serious than a noun; they had not represented a concrete reality. But that mental conception had passed now, routed by the odour that clung in his nostrils. He was not afraid; but realising for the first time, that he was in actual danger, he advanced more warily, always on the alert.
Some marshy ground and several deep ravines had necessitated various detours. It was already almost noon, the time upon which he was determined he must turn back in order that he might reach the point where he had left his guide before darkness fell upon the jungle. Constantly for some time there had lurked within his consciousness a question as to his ability to back-track upon his trail. He had had no experience in woodcraft, and he had already found it far more difficult than he had imagined it would be to maintain a true course by compass; nor had he taken the precautions to blaze his trail in any way, as he might have done by marking the trees with the heavy trail cutter that he carried.
Gordon King was disgusted with himself; he had found no ruins; he was hot, tired and hungry. He realised that he had lost all interest in ruins of any and all descriptions, and after a brief rest he turned back towards the south. It was then, almost immediately, that he realised the proportions of the task that lay ahead of him. For six hours he had been plodding deep into the jungle. If he had averaged two miles an hour, he had covered a distance of twelve miles. He did not know how fast he had walked, but he realised that twelve miles was bad enough when he considered that he had started out fresh and well fortified by a hearty breakfast and that he was returning empty, tired, and footsore.
However, he still believed that he could make the distance easily before dark if he could keep to the trail. He was well prepared physically by years of athletic training, having been a field and track man at college. He was glad now that he had gone in for long distance running; he had won a marathon or two and was never appalled at the thought of long distances to be covered on foot. That he could throw the javelin and hurl the discus to almost championship distances seemed less helpful to him in an emergency of the present nature than his running experience. His only regret on this score was that during the year that he had been out of college he had permitted himself to become soft—a condition that had become increasingly noticeable with every mile that he put behind him.
Within the first minute that Gordon King had been upon the back-trail toward his guide he had discovered that it was absolutely impossible for his untrained eyes to find any sign of the trail that he supposed he had made coming in. The way that he thought he had come, his compass told him, let towards the south-west; but he could find no directing spoor.
With a shake of his head, he resorted again to his compass; but due south pointed into a dense section of jungle through which he was positive he had not come. He wondered whether he should attempt to skirt every obstacle, thereby making long and wide detours or continue straight toward the south, deviating from his direct line only when confronted by insurmountable obstacles. The latter, he felt, would be the shortest way out of the jungle in point of distance, and he was confident that it would bring him as close to his Cambodian guide as any other route that he might elect to follow.
