There were only four pack mules to carry these things, but every member of the party carried a heavy pack on his shoulders, besides his gun and axe, so that altogether the expedition was reasonably well provisioned, in view of the fact that it was going into the mountains where game of every kind abounded.
No provender was carried for the pack mules. There was grass enough for them to live upon during the journey of two days and at the end of that time they were to be turned loose to find their own way down the mountain, cropping grass and herbs as they went.
There was a grind stone for the sharpening of the axes, and one of the boys carried a long cross-cut saw. The ammunition supply was large, and besides cartridges loaded with turkey shot it included several scores that carried full sized buck shot. The ammunition, added to the rest, very seriously over-loaded the mules. On a long journey those animals, large and brawny as they were, could not have endured the burdens laid upon them. But the trip up the mountain was to occupy a good deal less than two days and so the owner of the mules readily consented to the overloading.
That is how it came about that the five boys and Doctor LaTrobe were camping up there in a little mountain glade, on the night on which our story opens. They had less than a mile to go on the next day in order to reach their permanent camping place, but the journey was mainly a very steep up-hill one, and, their halt on the mountain side was in every way wise.
Healthily weary as they were it did not take the boys long to fall asleep after they had wrapped themselves in their blankets and lain down with feet toward the great blazing fire.
It was understood that the one on sentry duty should replenish the fire from time to time, but at Jack's wise suggestion the sentry was himself to remain well away from the blazing logs, and in the shadow of the woodlands beyond.
"Otherwise," explained Jack, "an enemy approaching in the dark might easily pick off our sentry, sitting or standing in the firelight, and then slip away in the darkness without the possibility of our seeing him."
The hours wore away, however, with no disturbance in the camp. One after another sentry aroused his successor and himself lay down to sleep.
It was nearing daybreak, and little Tom was on duty. There was already a rime of white frost on the grass and leaves and the atmosphere was chill. Tom looked longingly at the great blazing fire as he walked his beat in the woodland shadows far beyond reach of its comforting radiance.
"Any how this snappy air keeps a fellow from sleeping on post," he said to himself, "and they punish that crime with death in the army. Whew! how my ears ache!
