"I don't know why they shouldn't," returned her companion.
"It might be dangerous, perhaps," suggested Lulu.
"Why should it?" said Betty; "it's almost as light as day. Oh, Bob," perceiving her brother close at hand, "don't you want to go in? I will if you will go with me."
"I don't care if I do," he answered, after a moment's reflection: "a moonlight bath in the sea would be something out of the common; and there seems to be just surf enough to make it enjoyable."
"Yes; and my bathing-suit is in the bath-house yonder. I can be ready in five minutes."
"Can you? So can I; we'll go in if only for a few minutes. Won't you go with us, Lulu?"
"I'd like to," she said, "but I can't without leave; and I know papa wouldn't give it, for I had a bath this morning, and he says one a day is quite enough."
"I was in this morning," said Bob; "Betty, too, I think, and—I say, Bet, it strikes me I've heard that it's a little risky to go in at night."
"Not such a night as this, I'm sure, Bob; why, it's as light as day; and if there is danger it can be only about enough to give spice to the undertaking."
With the last word she started for the bath-house, and Bob, not to be outdone in courage, hurried toward another appropriated to his use.
