"Isn't she a funny woman, Miss Wyman?" Joan asked when they had closed the farmhouse gate behind them. "She is always asking me about daddy. Every day she asks me if he is an American citizen or if he isn't. And when I asked daddy he said he couldn't be an American citizen because he isn't through with being another kind of a citizen yet."

"He's a Luxembourger, you know, Joan. Why didn't you tell Mrs. Erickson that?"

"I did, and she just sniffed and said she never heard of such a country. She sniffs awfully funny, Miss Wyman, but she's kind, too. She gave me a doughnut and a piece of cheese as well as a gooseberry tart. She said they'd probably make me sick but I could eat them if I wanted to. And I wanted to, and I wasn't sick. She makes awfully good doughnuts. I think she must be a good cook. The chickens liked their dinner awfully much."

"Positive proof that Mrs. Erickson is the perfect cook. None but the best would do for a flock of hungry chickens. Joan, I'll race you to the house. Wait a minute. Now, one—two—three—Go!"

And they were off, down the driveway, by the lilac bushes to the old oak where Peter and Wallie, on their way from the shop, stretched a barrier across the walk.

"You must be in a hurry," grinned Peter. "Hold on and we'll ride with you, but you must have some regard to the speed limit."

"Tired?" They did look hot and tired. "It must be horrid to spend a perfectly gorgeous day like this in a stuffy shop with a gasoline engine that says nothing but puff-puff. Aren't you almost through?"

"We'll never be through," moaned Wallie. "I expect the Major will keep us here on the job until we are gray and tottering. You'll be a dear little old lady then, Miss Wyman."

"Silly!" Rebecca Mary tilted her nose. "But, honest, won't you be through soon? Granny and I have been perfect saints. We haven't made any fuss at all, but we can't stay here forever. Of course, I don't know anything about your great experiment——"

"It is great, all right!" interrupted Peter. "The more we work at it the more sure I am of that. I don't wonder old Germany moved heaven and earth to get hold of it."
