About midnight
I thought I could trust him to hear any sound for three or four hours , and I tried to sleep , but I could n't . Every few minutes I went up a short ladder and put my head out the scuttle in the roof to look and listen . I heard a good deal , but except for the wolves away off it was all in my ears . About midnight by the stars I went to sleep in my chair before I knew it . When I woke up I gave a great jump . It seemed as if I had been asleep a week ; and it certainly had been several hours . Kaiser was sitting on the floor beside my chair .
