"The Lord knows. I can see them down there holding a consultation. Move over here and you can see the whole valley. Don't be afraid; they can't see us." She moved over timidly. Crouching side by side they watched the operations below. The visitors, evidently mystified by the footprints, were huddled together, gesticulating wildly. They ran hither and thither like so many ants, minutely examining the mysterious tracks. After a long time Hugh gave vent to an exclamation. "By George! I know what's the matter. They can't understand the prints of our shoes. Our naked footprints are clear enough to them, but I'll bet my soul they've never seen an impression made by a shoe. They are your and my footprints, you know, with and without shoes." "Mine? Why, Hugh Ridgeway, I--never--oh, I never thought!" she exclaimed, deeply embarrassed after her first expression of wonder and incredulity. Then she leaned forward and strained her eyes as if expecting to see the slender little bottoms of her feet in the tell-tale sand. At that moment the brown band divided into squads, a half dozen coming toward the mountain, the others remaining with the boats. "They are after us, Tennys. I have no weapon but this club, but I will use it as long as I can stand. I'll protect you to the last. If they kill me, the only thing left for you to do is to crawl to the ledge over there and jump off. We must not be taken." She felt a strange sense of confidence and security in the broad back of the man beside her. His jaw was set. His cheeks pale, his eyes burning with the intensity that thrilled his whole being. The strong white hand clutched the club fiercely. He was no longer the light-hearted, inconsequent youth she had known on board the ship. The brown figures came into sight again, flitting here and there, pausing in wonder beside the stone table, inspecting the cracked nuts critically, and closely examining the ground on all sides. At last four or five of them sped up the ledge to the cave. "They have found our hotel," said Hugh grimly. She gulped and could do no more than nod. A tall fellow with a long spear and a huge shield, stripped to the loins, about which was a white cloth, ventured up the slope. Suddenly he halted and called his companions to his side. He had found a footprint in a bit of sand on the rocky surface. Without more ado the squad scattered and began the ascent, each man eyeing the ground eagerly. Occasionally those nearest the centre would pause and point to a track. "The good Lord help us!" murmured Ridgeway.
