His intention was to work back toward the house from this point, zigzagging to cover as much territory as possible before dark. The first zig, he decided, should take him straight up the side of the hill to the south, thus crossing any possible trails cutting around this side of the mountain. After reaching the top, he could decide whether to go down the other side at once, or head west a short distance before sweeping back to the north. As it turned out, he never had to make that decision.

Roger Wing was not, of course, as competent a tracker as he liked to believe. As a matter of fact, he had crossed the trail he was so diligently seeking four times since leaving the house. His present location was at the foot of the hill bearing the open slope which the “miners” had crossed the day before, and within a mile of the Sarrian homing station. The course he now took uphill would have led him within a few rods of the transmitter.

However, he didn’t get that far. Donald had been perfectly correct in concluding that no one could cross that slope of loose rock without leaving traces. Roger failed to recognize the marks left by the two on the way out, but he did find where his brother had forced his way through an unusually thick patch of brush at the top of the scree on the way back. It was carelessness on the older boy’s part, of course; his attention at the time had been mainly taken up with the search for tracks left by the possible followers, and he had paid no attention to those he himself was leaving. While the broken bushes gave Roger no clue to the traveller’s identity, they indicated his direction very clearly; and the boy promptly turned westward. Had he stopped to think, it would have occurred to him that a trail in this direction hardly jibed with the assumption that his father and brother were going straight to the “mine”; but he was not thinking at the moment. He was tracking, as he would have told anyone who might have asked.

Once out of the patch of brush, the trail was neither more nor less obvious than it had been all along; but Roger was able to follow it. Probably the assurance that there was a trail to follow had something to do with that. He still did not know whether the traces had been left by his father, his brother, or both. He also failed to recognize the point where the two had come together after covering both sides of the scree. He simply went on, picking out the occasional scuff in the carpet of fir needles or snapped twigs where the bushes were thicker. He descended the west side of the hill, after following it around from the point where the first traces had appeared. He crossed the narrow valley on this side, leaping the inevitable brook with little difficulty. Here he found the only assurance that he was actually following two people, in the indentations where they had landed on the bank after a similar leap. The marks were just dents, for the needles did not retain any definite shoe patterns, but there were four of them. They were in two pairs, one of each deeper than its fellow, as though the jumper had taken the shock of landing principally on one foot.

Up the side of the next hill the boy went. It was darker now under the trees, for the sun was already concealed by the peak ahead of him; and presently he began to wonder whether he were really on the right trail. He stopped, looking about, and saw first to one side and then the other marks of the sort he had been following. He could not, he found, convince himself that those ahead of him were the right ones.

He tried to go on, then hesitated again. Then he began to backtrack — and reached the brook many yards from the spot at which he had jumped it. He spent some minutes searching for the marks, and when he had found them realized that he had not even followed his own back trail with any accuracy.

He should, of course, have headed for home right then. Equally, of course, he did nothing of the sort. While the gloom on the mountain’s eastward face grew ever deeper, he cast about for tracks. Every few minutes he found something, and spent long seconds over it before deciding to make sure — and then he always found something else. Gradually he worked his way up the mountain side, finally reaching open rock; and after deep thought, he moved around to the other side where it was lighter, and resumed his search. After all, the men had been heading westward.

He had crossed another valley — this time its central watercourse was dry, and there was no sign of anyone’s jumping over — and was near the top of the unusually low hill on its farther side when he finally realized the time. He had been searching with a single-mindedness which had prevented even hunger from forcing itself on his attention. The sheer impossibility of seeing details on the shadowed ground was all that finally compelled him to consider other matters. He had no flashlight, as he had not contemplated remaining out this late. Worse, he had neither food, water, nor a blanket. The first two were serious omissions, or would be if his father heard of his venturing any distance into the woods without them.

It was quite suddenly borne in upon Roger Wing, as he saw the first stars glimmering in the deepening blue between the tree tops, that he was not another Daniel Boone or Kit Carson. He was a thirteen year old boy whose carelessness had gotten him into a situation that was certainly going to be uncomfortable and might even be serious.

Though rash, Roger was not stupid. His first action upon realizing the situation was not a wild break for home. Instead he sensibly stood where he was and proceeded to plan a course of action.
