“Have you ever had the fever?” he asked.

“I am not sure. I think I had it when I was a child. But I am not afraid of it.”

“When you were a child! That could not have been a long time ago, I should imagine,” said the doctor, smiling a little, as he looked into the earnest face turned towards him. “But I dare say you will do as well for Harry as Nurse Greenly herself could do.”

“Is he in danger? Is he worse than Letty was?” asked his mother.

“Oh, no! He is by no means so ill as she was at one time,” said the doctor, cheerfully. “And a fine rugged little fellow like Harry may get through much better than his sister. But, at the same time, this fever sometimes becomes more severe as the season advances, and it is as well to keep the other children away. Not that I think there is any particular danger for any of them—even the baby; but being weaned so young, and her teeth coming, it is as well to be cautious. So if Christie is to nurse Harry, she may as well have nothing to do with the baby—or the boys.”

Mrs Lee looked still harassed and anxious.

“There is no harm done,” continued the doctor, soothingly. “If Christie has to be with the other children, she should not be with Harry. But if Harry is so fond of her, perhaps she had better stay with him to-night, at any rate. I dare say you can manage without her up-stairs for one night?”

“Oh, yes! we can do very well,” said Mrs Lee.

“When do you expect Mr Lee home?” asked the doctor.

Mrs Lee shook her head. “I have been expecting him every day for a week. He must come soon, now, or write. He has not yet heard of Letty’s illness. I was so glad it was over before he came! and now Harry, and perhaps the others—” She stopped short, but soon added, “I hope nurse will not need to go.”
