Toby was of great use to Mrs. Jones; she said that he was as good as a nurse. Every day she used to put Susie to sleep in a room at the head of the garret stairs. Then she would call the dog, and leave him to take care of the baby while she went about her work; and it seemed as if Toby knew the right hour for Susie's nap, for he was never out of the way at that time. He would lie and watch her till she woke up, and then go to the head of the stairs and bark till Mrs. Jones came. Then he knew that his duty was done, and he would walk gravely down stairs. Sometimes Mrs. Jones put Susie on the kitchen floor, and left Toby to look after her. He would let her crawl all round unless she went near the fire, or the open door or kitchen stairs, when he would take her by the waist and lift her back to the place where her mother had left her. Susie would scold him as well as she knew how, and pound him with her little fist; but he did not care one bit for that.
