Wallace bent over the map and drew a double line. “This,” he said, “is the stream, west of our camp site. The cave, therefore, should be directly south. In that case we have to return to camp and—”

Jack interrupted. “No,” he said, “we won’t do that. We’ll cut across.”

Wallace approved the plan. Rising, the boys determined by compass the exact direction they had to follow. The first thing they had to do was to drop from the ledge about eight feet below. After that, they were obliged to take a descending route and at the same time cut across in the general direction of the camp. Pretty soon they reached a level plateau heavily wooded. Indian file, one behind the other, they walked along slowly and carefully. Suddenly they came upon a large clearance, circular and with possibly a little less than half a mile radius. Jack lay down on his stomach and Wallace did likewise. Jack said, “Quick, seeing this field, what’s the first thing that comes to your mind?” Wallace shook his head. Jack added, “Remember the airplane circling overhead this morning? Now put two and two together.”

Wallace whistled. “An airport!” he exclaimed.

“Correct!”

For a while they continued lying on their stomachs and carefully examined the field and the outlying woods. Absolute silence reigned. Not a sound, not a moving shadow, as far as they could see or hear. Finally Wallace whispered, “What now?”

The two boys rose and, single file, Jack leading, they walked through the woods, keeping within sight of the clearing but trying hard to keep themselves hidden. Jack stepped on a twig and it snapped, the sound echoing loud through the dead silence of the woods. He stopped and the two boys remained rooted to the spot for at least five minutes. They continued. Every once in a while they strained their ears to listen. Not a sound. Wallace suggested they again approach the edge of the clearing. Getting down on their hands and knees they crept up to the very edge of the woods. Lying on their stomachs, they let their eyes roam all around the field. Suddenly Jack grasped Wallace by the wrist. “Ouch!” he cried.

Jack cautioned him to be silent. “Sh!” he hissed and put a finger over his lips. Then he pointed. Wallace shook his head; he saw nothing. Again Jack pointed, but his friend still saw nothing. “You remain here and keep your eyes wide open. I’m going to creep out and get it.” He crept forward on his stomach for about ten feet, then crept back, dragging something along. Crouching alongside his friend, he showed him the object and whispered, “Rifle!”

Wallace nodded. “What’s your opinion?” he asked.

His companion shook his head. “Don’t know,” he whispered.
