I was not sorry, however, to eat some of the venison which the Indians gave me; and then I lay down and pretended to go to sleep.  They sat up feeding for some time after this; then, greatly to my disappointment, one got on his feet and began to walk backwards and forwards, while the rest stretched themselves on the ground, as they had done the night before.  I watched and watched, and at last believing that they were too cunning to allow me to escape, I closed my eyes and went to sleep.  I awoke twice, and on each occasion observed that one of them was on the watch.
