At last a change came in a rather unexpected manner. George lodged at his master's house, and when he went out to play was accustomed to leave a window unfastened so that he could let himself in without rousing the household. Somehow or other his master found out this plan, and determined to put a stop to it. So one night when George had gone out he nailed down the window, and when the apprentice returned home in the early hours of the morning he found himself locked out. Nothing daunted he climbed on to the roof and managed to get in through his bedroom window.
