The sentinel on the outpost or the watch on deck fights off his drowsiness by steadily pacing back and forth. If he sits down for a few minutes he is sure to succumb.
When Fremont, the pathfinder, was lost with his command in the Rocky Mountains, and was subjected to such arctic rigors in the dead of winter as befell the crew of the Jeannette in the ice-resounding oceans of the far north the professor, who accompanied the expedition for the purpose of making scientific investigations, warned all that their greatest peril lay in yielding to the drowsiness which the extreme cold would be sure to bring upon them. He begged them to resist it with all the energy of their natures, for in no other way could they escape with their lives.
And yet this same professor was the first one of the party to give up and to lie down for his last long sleep, from which it was all Fremont could do to arouse him.
Fred Sheldon felt that everything depended on him, and with the exaggerated fears that come to a youngster at such a time he was sure that if he fell asleep the evil man would enter the room, take all the money and plate and then sacrifice him.
"I could keep awake a week," he muttered, as he tipped his chair back against the wall, so as to rest easier, while he leaned the musket along side of him, in such position that it could be seized at a moment's warning.
The night remained solemn and still. Far in the distance he could hear the flow of the river, and from the forest, less than a mile away, seemed to come a murmur, like the "voice of silence" itself.
Now and then the crowing of a cock was answered by another a long distance off, and occasionally the soft night wind stirred the vegetation surrounding the house.
But among them all was no sound which the excited imagination could torture into such as would be made by a stealthy entrance into the house.
In short, everything was of the nature to induce sleep, and it was not yet ten o'clock when Fred began to wink, very slowly and solemnly, his grasp on the ruined weapon relaxed, his head bobbed forward several times and at last he was asleep.
