"'But, father,' said I, 'if the people have gone to bed you can't get into the house to play him your trick.' "'That can be managed,' says he; 'I'm rather old for climbing myself, but I know a way by which you, Thomas, can get in easy enough. At the back of the house is a trellis with a grape-vine running over it, and the top of it is just under one of the second-story windows. You can climb up that trellis, Thomas, and lift up that window-sash very carefully, so's not to make no noise, and get in. Then you'll be in a back room, with a door right in front of you which opens into Mr. and Mrs. Green's bedroom. There's always a little night lamp burning in it, by which you can see to get about. In the corner, on your right as you go into the room, is a table with my instrument-box standing on it. The box is pretty heavy, and there is a handle on top to carry it by. You needn't be afraid to go in, for by this time they are both sound asleep, and you can pick up the box and walk out as gingerly as a cat, having of course taken your shoes off before you went in. Then you can hand the box out the back window to me,--I can climb up high enough to reach it,--and you can scuttle down, and we'll be off, having the best rig on Williamson Green that I ever heard of in my born days.' "I was a very active boy, used to climbing and all that sort of thing, and I had no doubt that I could easily get into the house; but I did not fancy my father's scheme. "'Suppose,' I said, 'that Mr. Williamson Green should wake up and see me; what could I say? How could I explain my situation?' "'You needn't say anything,' said my father. 'If he wakes up blow out the light and scoot. If you happen to have the box in your hand drop it out the back window and then slip down after it. He won't see us; but if he does he cannot catch us before we get to the boat; but if he should, however, I'll have to explain the matter to him, and the joke will be against me; but I shall get my instruments, which is the main point, after all.' "I did not argue with my father, for he was a man who hated to be differed with, and I agreed to help him carry out his little joke. We took off our shoes and walked quietly to the back of the house. My father stood below, and I climbed up the trellis under the back window, which he pointed out. The window-sash was down all but a little crack to let in air, and I raised it so slowly and gently that I made no noise. Then without any trouble at all I got into the room. "I found myself in a moderate-sized chamber, into which a faint light came from a door opposite the window. Having been several hours out in the night my eyes had become so accustomed to darkness that this light was comparatively strong and I could see everything.
