Convinced though Stern now was of the reality of the amazing sight he had just witnessed through his binoculars, yet for a long moment he remained silent and staring, utterly at a loss for any rational explanation of the remarkable apparition.
Exhausted in body and confused in mind, he could hit upon no answer to the riddle.
Might these be some detached and belated members of the Horde? No; for their figures and their gait, as he now for the third time studied them through the glass, were unmistakably human.
But if not Anthropoids, then what? Enemies? Potential friends? Some new and strange race, until now undiscovered?
A score of possible explanations struggled in his mind, only to be rejected. But this was now no time for questions, analysis, or thought. For, even as he looked, the end of the line came to view, then vanished down the blackened hillside.
Invisible, now that they no longer stood silhouetted against the sky-line, the strange company had disappeared as though swallowed up by the earth. Yet Stern well knew that they were coming almost directly down upon him and his little party. Already there was pressing need for swift decision.
What should he do? Advance to meet these strangers? Risk all on a mere chance? Or turn, retreat and hide? Or ambush them, and kill?
He found himself, for the moment, unable to make up his mind. Yet, should a pinch arise and the last contingency become necessary, he felt a powerful advantage. He was positive his little band, armed as they were, could easily wipe out this column. But, after all, must he fight?
His questions all unsettled and his mind confused from the terrible exhaustions of the march, he waited. He surveyed the neighborhood, with a view to possible battle.
On his left rose a ridge that swung to northward between the advancing column and his own position. On his right an arroyo or gully, choked with fallen tree-trunks and burned forest wreckage, descended in an easterly direction toward a rather deep valley. In this gully he saw was ample hiding-place for his whole force.
"Men!" he addressed them; "it is strange to tell, but there be others who come against us there!" He pointed at the far crest of the sawlike highlands, where now he thought to see a hazy, floating pall of dust.
"Until we know their purpose and their temper we must have care. We must hide ourselves and wait. Come, then, quickly! And prepare your guns against the need of battle!"
His words aroused and heartened his exhausted men. The prospect even of war was welcome--anything in place of this unending trek through the burned wilderness.
