The bridge was three-quarters open when the boy noted with some surprise that the man on the sloop had thrown over the mainsail half against the wind. Instantly the sloop began to swing around, heading full for the stone pier upon which the bridge swung.

"Why, what's the matter with him?" he cried, in dismay.

"Guess he don't know how to manage his boat," replied Bob Sanderson. "He's comin' chuck-a-block for this place!"

"Hi! hi! what are you up to?" cried Ralph, as he dropped the bar, and rushed over to the side of the bridge. "Do you want to run into the stonework?"

"I can't manage the sail!" replied the man on the sloop. "My arm is lame, and the ropes are all twisted."

"Well, throw your tiller over, and be quick, or——"

Ralph had not time to say more, nor was the man able to profit by his advice. An extra heavy puff of wind caught the mainsail of the boat, and with a loud crash she clashed into the stone pier, bow first.

The shock was so great that the bowsprit was smashed to pieces, as was also the woodwork around it. The man, who had been standing partly on the stern sheets, was thrown overboard by the accident, and he disappeared beneath the water.

Fearful that the fellow, who was evidently a city person, might not be able to swim, Ralph leaped down from the bridge into the sloop and went to his assistance.

"Save me! save me!" called out the man, frantically, and he threw his hands up over his head.
