So when Diamond went home, he told his father all about it. But when his father went to see about it, he found that he must agree to work the horse only six hours a day. Then too he must take Nanny from the hospital and feed her, and teach her to be useful and keep her as long as he had Mr. Raymond's horse. Diamond's father could not help thinking that it was a pretty close bargain and so it was. Mr. Raymond wanted to find out if Diamond's father was the kind of man who was willing to help some one else without getting any advantage out of it for himself. Then it would be worth while to help him. Diamond's father was that kind of a man. So when he heard all about Nanny, he decided to accept Mr. Raymond's offer and do the best he could.
Nanny was not fit to be moved for some time yet and Diamond went to see her as often as he could. But he went out to drive old Diamond every day now for a few hours at least. Then he had to help mind his baby brother for part of the time. So he did not go to the hospital as often as he would have liked. When he did go, he sat by Nanny's bed and told her all that had happened to him since he had been there before. In her turn Nanny would tell him of what went on in the hospital—what visitors they had and things like that.
"Day before yesterday," said Nanny one day, "a lady came to see us. She was a very beautiful lady. She sat down beside my bed and let me stroke her hand. She had on a most beautiful ring with a rich red stone in it. When she saw me looking at it, she slipped it off her finger and put it on mine. She said I might wear her lovely ruby for a little while if it would make me happy."
"Her ruby!" cried Diamond. "How funny that is! Our new horse's name is Ruby. And we took him so that we could take you to live with us, while you are getting strong again. I do believe a ruby is for good luck!"
"It did me good right then," said Nanny. "For that night I had such a lovely dream. It began with a red sunset like my darling ruby ring. Then somehow a wind came out of it and blew me along out of the dirty streets into a yard with a lovely lawn of soft grass."
"That was North Wind, I know!" cried Diamond. "That is what she does to me."
"I do not know what you mean," said Nanny. "I do not know anything about North Wind. But all at once there was no more ruby sunset but a great golden moon hanging very low and seeming to be shining just to be good to me. It was easy, I suppose, for me to dream about the moon. I've always been used to watching her. She was the only thing worth looking at in our street, at night."
"Don't call it your street," said Diamond. "You are not going back to it. You are coming to us, you know."
"That is too good to be true!" said Nanny.
