"I'll have to, won't I?" innocently inquired the stout youth.

"Yes, or——"

"Never mind about that," spoke Blinky sharply. Then cupping his hands to his mouth, he shouted upward:

"Haul away! Slow, now!"

He placed his fingers on the taut rope and felt it slip upward through them.

"Good old ropes," he murmured; "stretched like a fiddle string and sound as a ship's cable."
