At first I was nearly roasted out, for I lay against one side of the camp, and felt the heat reflected not only from the birch-bark above, but from the side; and again I remembered the sufferings of the Jesuit missionaries, and what extremes of heat and cold the Indians were said to endure. I struggled long between my desire to remain and talk with them and my impulse to rush out and stretch myself on the cool grass; and when I was about to take the last step, Joe, hearing my murmurs, or else being uncomfortable himself, got up and partially dispersed the fire. I suppose that that is Indian manners,—to defend yourself.
