"As we must be off by daylight, it is now time to turn in," said the lieutenant. "Suppose you keep one eye open, and I another! We must not, if we can help it, be surprised by wolves or bears—nor Indians either. It is just possible that the fellows whom we saw in the afternoon may follow us."

"Then I will sit up and keep watch while you sleep," I said. "If they come at all, they will try and steal upon us when they think that we may be asleep."

"I agree to your proposal," answered my companion. "If you will call me in a couple of hours, I will then take my turn, and thus let you have the morning watch. I am accustomed to have my sleep broken."

Nothing occurred during the first watch, and at the end of it I roused up the lieutenant and lay down. I suspect that he had intended to keep on watch for the rest of the night; but I happened to awake, and insisted—finding he had had a long spell—on his lying down. The young officer, therefore, rolling himself in his buffalo robe, was again quickly asleep.

I sometimes walked up and down, my rifle in my hand; sometimes leaned against a tree, peering in every direction. It could not then have wanted more than a couple of hours to dawn. The only sounds which reached my ear were those from our animals as they cropped the rich grass, or the occasional scream of some night-bird in the forest. The moon, too, was nearly at its full, and I was thus enabled to see objects at a distance distinctly. I could judge pretty well of the hour by the appearance of the fire, on which, from time to time, I threw a few sticks to keep up the blaze.

I was leaning against a tree, beginning to feel somewhat sleepy, and thinking that it would soon be time to call the lieutenant, when a sound as of something moving in the forest behind me struck on my ear. I remained perfectly motionless, and again I heard the sound. "It may be a bear," was my first thought; "but then, a bear moving among the bushes would make more noise than that. It must be some human being; perhaps an Indian, who is watching an opportunity to shoot us down."

I kept completely in the shade, while I turned my eyes in the direction from whence the sound came. I thus hoped, should there be an enemy near, to get sight of him before he could discover me.

On arousing the lieutenant, I told him of the sounds I had heard.

"If there are Indians near, we had better at once go in search of them," he answered. "I have no fancy to be shot down, as you suppose it likely we may be; and as it will not do to leave our horses, I propose that we mount them, and try and push through the forest. The moonlight will enable us to make our way without difficulty."

I should have preferred going on foot, but, of course, there was a risk, as the lieutenant had observed, of our horses being carried off. I therefore thought it wisest to agree to his proposal.
