"I'm not afraid of it," said Matt, his natural bravery pushing him to the front at such a crisis. "Let me try."
"I hold big rock in one hand an' little rock in t'other. Fellow that guesses big rock goes," said Chick-chick.
"Right!" said Matt.
"An' Brick guesses left," said Chick-chick for Glen. "Matt gets the try."
"I know just about where the opening lies," he said, stepping on the pile of masonry. "I'll dive clear through the passage."
With a quick spring he disappeared beneath the turbid water.
The boys waited an anxious minute, swinging their lanterns far out over the current. Suddenly Glen thrust the lantern he held into Apple's hand and made a quick jump into the swirl of waters. He was up in a moment with a heavy burden.
"It's Matt!" he cried. "I saw his hand sticking out of the water and jumped for it. He's hurt himself."
The boys were down by his side in a moment, Apple holding a lantern high above his head.
