ys are planning anything for to-night?" mused Miss
Elting, a moment after turning out the lights.

"Yes," answered Harriet confidently, as if she had been consulted.

"What?" demanded a chorus of voices.

"They are planning to go to bed. I saw them fixing the fire, just before
I got into bed."

"Oh, fudge!" groaned Margery.

"Thave me!" wailed Tommy.

Jane suggested that Harriet ought to have a ducking, then one by one the
girls dropped off to sleep.

The clock that Harriet consulted showed the hour to be ten minutes after
midnight. She had awakened suddenly, and with a feeling that something
were not as it should be. The girl rose softly, peering through the
window. The "Red Rover" was lying very quietly, there being little
movement of the water. No one was about, nor was there a boat in sight.
She stepped out on the deck, glancing about in all directions, her eyes
finally fixing themselves on the camp of the Tramp Club.

bringing her glasses, peered through them at the camp of the tramps.
"Yes, they are up to mischief of some sort," she decided, lowering the
glasses and laying them aside. "Girls!"

"Wha--wha-at?" cried Jane, her feet landing on the floor almost ere the
words were out of her mouth.

Tommy hopped out of bed a few seconds behind Crazy Jane, but instead of
landing on her feet, the little girl went sprawling on the floor on her
face.

"Thave me! Are we thinking?" she cried.

"No, you foolish girl. We aren't sinking," answered Harriet laughing.

Margery stood shivering in the middle of the cabin. Hazel had begun to
