"I'm not," answered Roy, adding with a grin, "Nothing half so honest."

Although the girls knew that they were only saying good-bye to the boys for a few days, the parting was hard just the same, and half an hour later they watched the train wind serpent-like down the shining track with a sinking feeling at their hearts.

"Aren't we a lot of geese?" said Grace impatiently, as they climbed back into the cars. "We have done without the boys for a couple of years, and now when they have just gone as far as Deepdale for a couple of weeks, we are almost crying about it."

"I suppose it is just because we have had so much separation that we can't bear any more of it--even a little," suggested gentle Amy, feeling as if she had just awakened from a blissful dream.

"Never mind," said Mollie, putting an arm about Betty's waist and giving it a little squeeze. "Just think how lovely it will be to see the boys in regular clothes again, and maybe," with a sly glance at Betty, "by the time they come back they will have added one to their number."

"Goodness, I hope so!" said Betty, unashamed.

In spite of some regret at not having the boys, the girls managed to enjoy themselves in the days that followed. They motored and swam and fished and hiked, and got as becomingly sun-burned and tanned as young Indians. It was not until two or three days before the boys returned that anything untoward happened to disturb their peace of mind.

Then one night the moon came out with such dazzling brilliance that Betty was seized with a strong desire to be out in it.

"Let's go for a moonlight swim," she suggested excitedly, as they all stood on the porch of the lodge staring up through the trees to where the moon shone glitteringly down. "We haven't done it since we came, and surely our vacation wouldn't be complete without one."

"Or more," said Mollie, seconding the plan with enthusiasm. "Come on. Let's tell Mrs. Irving where we are going. Maybe she will wish to go along, but I doubt it."
