What the words were Joe could not understand, but to him they sounded like French. He smiled at the absurdity of imagining he had heard a savage speak a foreign language. At any rate, whatever had been said was trenchant with meaning. The Indians changed from gay to grave; they picked up their weapons and looked keenly on every side; the big Indian at once retied Joe, and then all crowded round the chief.
"Did you hear what Silvertip said, and did you notice the effect it had?" whispered Jim, taking advantage, of the moment.
"It sounded like French, but of course it wasn't," replied Joe.
"It was French. 'Le Vent de la Mort.'"
"By Jove, that's it. What does it mean?" asked Joe, who was not a scholar.
"The Wind of Death."
"That's English, but I can't apply it here. Can you?"
"No doubt it is some Indian omen."
The hurried consultation over, Silvertip tied Joe's horse and dog to the trees, and once more led the way; this time he avoided the open forest and kept on low ground. For a long time he traveled in the bed of the brook, wading when the water was shallow, and always stepping where there was the least possibility of leaving a footprint. Not a word was spoken. If either of the brothers made the lightest splash in the water, or tumbled a stone into the brook, the Indian behind rapped him on the head with a tomahawk handle.
At certain places, indicated by the care which Silvertip exercised in walking, the Indian in front of the captives turned and pointed where they were to step. They were hiding the trail. Silvertip hurried them over the stony places; went more slowly through the water, and picked his way carefully over the soft ground it became necessary to cross. At times he stopped, remaining motionless many seconds.
This vigilance continued all the afternoon. The sun sank; twilight spread its gray mantle, and soon black night enveloped the forest. The Indians halted, but made no fire; they sat close together on a stony ridge, silent and watchful.
Joe pondered deeply over this behavior. Did the Shawnees fear pursuit? What had that Indian chief told Silvertip? To Joe it seemed that they acted as if believing foes were on all sides. Though they hid their tracks, it was, apparently, not the fear of pursuit alone which made them cautious.
Joe reviewed the afternoon's march and dwelt upon the possible meaning of the cat-like steps, the careful brushing aside of branches, the roving eyes, suspicious and gloomy, the eager watchfulness of the advance as well as to the ear, and always the strained effort to listen, all of which gave him the impression of some grave, unseen danger.
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.
The break it made in that dead silence was awful. Joe's blood seemed to have curdled and frozen; a cold sweat oozed from his skin, and it was as if a clammy hand clutched at his heart. He tried to persuade himself that the fear displayed by the savage was only superstition, and that that moan was but the sigh of the night wind.
The Indian sentinel stood as if paralyzed an instant after that weird cry, and then, swift as a flash, and as noiseless, he was gone Into the gloomy forest.
He had fled without awakening his companions.
Once more the moaning cry arose and swelled mournfully on the still night air.
It was close at hand!
"The Wind of Death," whispered Joe.
He was shaken and unnerved by the events of the past two days, and dazed from his wound. His strength deserted him, and he lost consciousness.
