And now as he lay on the hard ground, nearly exhausted by the long march and suffering from the throbbing wound, his courage lessened somewhat, and he shivered with dread. The quiet and gloom of the forest; these fierce, wild creatures, free in the heart of their own wilderness yet menaced by a foe, and that strange French phrase which kept recurring in his mind—all had the effect of conjuring up giant shadows in Joe's fanciful mind. During all his life, until this moment, he had never feared anything; now he was afraid of the darkness. The spectral trees spread long arms overhead, and phantom forms stalked abroad; somewhere out in that dense gloom stirred this mysterious foe—the "Wind of Death."
Nevertheless, he finally slept. In the dull-gray light of early morning the Indians once more took up the line of march toward the west. They marched all that day, and at dark halted to eat and rest. Silvertip and another Indian stood watch.
Some time before morning Joe suddenly awoke. The night was dark, yet it was lighter than when he had fallen asleep. A pale, crescent moon shown dimly through the murky clouds. There was neither movement of the air nor the chirp of an insect. Absolute silence prevailed.
Joe saw the Indian guard leaning against a tree, asleep. Silvertip was gone. The captive raised his head and looked around for the chief. There were only four Indians left, three on the ground and one against the tree.
He saw something shining near him. He looked more closely, and made out the object to be an eagle plume Silvertip had worn, in his head-dress. It lay on the ground near the tree. Joe made some slight noise which awakened the guard. The Indian never moved a muscle; but his eyes roved everywhere. He, too, noticed the absence of the chief.
At this moment from out of the depths of the woods came a swelling sigh, like the moan of the night wind. It rose and died away, leaving the silence apparently all the deeper.
A shudder ran over Joe's frame. Fascinated, he watched the guard. The Indian uttered a low gasp; his eyes started and glared wildly; he rose very slowly to his full height and stood waiting, listening. The dark hand which held the tomahawk trembled so that little glints of moonlight glanced from the bright steel.
From far back in the forest-deeps came that same low moaning:
"Um-m-mm-woo-o-o-o!"
It rose from a faint murmur and swelled to a deep moan, soft but clear, and ended in a wail like that of a lost soul.
