about ten o'clock
But situated as I was , I found it impossible to fix my mind upon the book ; and so I threw myself down upon the lounge to think over what had happened , and speculate as to the probabilities of the future . It may seem strange to some persons ; but , with all my comforts about me , I felt more homesick than I did when I was lying on the ice in my bearskin , or when I was poking about in the bowels of the earth , trying to see how I could get out . There was nothing to occupy my body ; and that , I suppose , was one reason why my mind worked as it did . At about ten o'clock , I went to bed , and , after tossing about uneasily for an hour or two , managed to fall asleep . When I awoke in the morning , it took me some time to remember where I was . I thought , at first , that I was at home , and could hear the birds singing by the window ; and I believe that I called out `` Bob ! '' once or twice before I was fairly roused .
