“Are you cold, dear?” her niece asked, with quick sympathy. “Here! I don’t really need this cape with my heavy sweater.”

She removed the heavy cloth garment from her own shoulders and with a flirt sought to place it around Aunt Kate. The wind swooped down just then with sudden force. The Stazy rolled to leeward.

“Oh! Stop it!”

Bulging under pressure of the wind, the cape flew over the rail. Jennie tried to clutch it again; Henri plunged after it, too. Colliding, the two managed between them to miss the garment altogether. It dropped into the water just under the rail.

“Of all the clumsy fingers!” ejaculated Helen. But she could not seize the wrap, although she darted for it. Nor could Ruth help, she being still farther forward.

“Now, you’ve done it!” complained Aunt Kate.

The boat began to rise on another roller. The cape was sucked out of sight under the rail. The next moment the whirling propeller was stopped—so abruptly that the Stazy shook all over.

“Oh! what has happened?” shrieked Helen.

Ruth started up, and Tom seized her arm to steady her. But the girl of the Red Mill did not express any fear. The shock did not seem to affect her so much as it did the other girls. Here was a real danger, and Ruth did not lose her self-possession.

Phil Gordon had shut off the power, and the motor-boat began to swing broadside to the rising seas.
