three o’clock
But I mean to be an artist , if you wo n't desert me . Do n't , my dear fellow ! I know I 'm a scamp ; but I 'll try and be a reformed character , if you will only stick by me . When you take your walk tomorrow , I shall be at the turnpike in the Laburnum Road , waiting for you , at three o'clock . If you wo n't come there , or wo n't speak to me when you do come , I shall leave England and take to something desperate . `` I have got a new friend -- the best and most interesting fellow in the world . He has been half his life in the wilds of America ; so , if you do n't give me the go-by , I shall bring him to see your picture of Columbus .
