"This isn't a vacation, you know," said Jack mildly. "I've hired out, at wages, and I'm to go to work to-morrow morning. And it is in the agreement that Mr. Hildreth is to 'board and lodge' me."

"Well, you can work for him and live here with us, too," suggested Rosemary comfortably. "Can't he, Mother?"

"It's ever so nice of you to want me," said Jack, "but you see, I've figured out that I want the complete experience; I want to get up when the other hired men do and eat breakfast when they do—Winnie wouldn't like to get me a six o'clock breakfast for the next two weeks—and I wouldn't let her, if she did."

"Richard doesn't think you'll stick it out for the whole two weeks," offered the placid Sarah, looking up from the book she was sharing with Shirley on the grass rug. "He said so."

Jack flushed, Doctor Hugh looked annoyed and Mrs. Willis sighed. Sarah's remarks usually aroused varied emotions.

"I think Jack is quite right," said the doctor firmly, before anyone could speak. "He wants to see this thing through and while he knows I'd like first rate to have him stay here at the house, I think he'd be handicapped from the start. There'll be the evenings left him, anyway, and Sundays—two of them at least."

"You must come to us for Sunday dinner," planned Mrs. Willis instantly. "I'll ask Richard and Warren, too; Winnie has wanted me to for some time, but there never seemed to be a mutually convenient time."

So Jack took his suit case over to the bungalow and was introduced to the little room next to the one shared by Warren and Richard. He had met Mr. and Mrs. Hildreth on one of his trips to Rainbow Hill with Doctor Hugh, but he had not seen Warren and Richard till this afternoon.

The three boys shook hands pleasantly. Jack was the youngest by a couple of years and not so deeply tanned; though, being an active lad and fond of outdoor sports, he had acquired a coat of brown since the closing of school. But he felt, looking at the other two, that he lacked their muscular advantage and a certain hardness that bespoke sturdy endurance.

"I'm ready to go to work," said Jack, in response to a question from Mr. Hildreth. "I've brought overalls and I'm said to be willing and obliging."
