"But I wish I knew!" sighed Betty.

"Yes," was all Allen answered.

Then something happened that for a time drove the mystery from their minds. It was after a particularly long and hard day, when the girls had been entertaining at the Hostess House all morning and part of the afternoon.

Then about three or four o'clock in the afternoon, they had gone downtown to do some very necessary shopping, and had been unable to get back to dinner till seven o'clock; and that evening the boys had arranged to take them to the theater.

By the time it was all over, and the boys had left them at the
Hostess House, they were very, very tired and very, very happy.

"I never felt so sleepy in my life," said Grace, sitting down on the edge of the bed and stretching her arms above her head. "And yet we've had such a good time. If somebody doesn't give me another chocolate I won't be able to stay awake long enough to get undressed. Thanks, Amy, you always were a friend of mine."

"Well, I never laughed so much in my life," declared Mollie, pulling off her slipper and wiggling her toes contentedly. "I think it's perfectly wonderful to go out with the boys in uniform. They look so splendid and we feel so very important."

"Goodness, don't you think they feel important, too?" yawned Grace.
"I know that Teddy Challenger does."

Teddy Challenger was a new-made friend of the boys, whom Allen had brought along for Amy, Will having refused to make one of the party on the plea of having important business to attend to.

"Oh, I don't know," said Betty, thoughtfully running the comb through her hair. "He seems like a mighty nice fellow to me and the boys all like him."
