It was a great delight to Diamond, when at length Nanny was well enough to leave the hospital and go to their house. She was not strong yet but Diamond's mother was very careful of her. She took care she should have nothing to do that she was not fit for. If Nanny had been taken straight from the street, it is pretty sure she would not have been so pleasant in a nice house nor so easy to teach. But the kindness they had shown her in the hospital while she was ill so long had changed her quite a little. As she got better, the colour came back to her cheeks, her step grew lighter and quicker, her smile shone out more readily, and it was clear she would soon be a treasure of help. It was great fun to see Diamond teaching her how to hold the baby and wash and dress him. Nanny had never had a little brother or sister to care for and she and Diamond often had to laugh over her awkwardness. But she was soon able to do it all as well as Diamond himself. Things, however, did not go very well with Diamond's father from the first coming of the horse, Ruby. It almost seemed as if the red beast brought bad luck with him. The fares were fewer and the pay less. Ruby's work did indeed make the week's income at first a little more than it used to be. But then there were two more to feed. After the first month, however, he fell lame, and for the whole of the next month, Diamond's father did not dare work him at all. It cost just as much to feed him and all he did was to stand in the stable and grow fat. And after he got well again, it was not much better. Times had then become hard and fewer and fewer people felt that they could afford to ride in cabs. The cabmen got fewer and fewer shillings to live on. Diamond's household had less and less to buy food and clothing with. Then too, Diamond's mother was poorly for a new baby was coming. Diamond's father began to feel gloomier and gloomier and if Diamond had not made himself remember that he had been at the back of the north wind, he would have been gloomy himself. But when his father came home, Diamond would get out his book and show him how well he could read. Besides he taught Nanny how to read and as she was a very clever little girl, she picked it up very fast. Nanny was such a comfort about the house that Diamond's father just had to cheer up a little when he came home at night and the dull day's work was over. After the new baby came, Diamond sang to her and of course he had to make up new songs to sing to her because she was a little sister baby. It would never do, he said, to sing the little brother songs to her. While he sang, his father and mother could not help listening and forgetting for the time how bad things were getting to be.
