"It's got to be done," said Uncle John. "I'll go first, if you don't mind."
"Go ahead, sir," said Hal.
Uncle John climbed to the sill, and then lowered himself until he hung by his hands.
"Here I go," he said.
He dropped.
"He's safe enough," said Chester, peering down, as Uncle John got to his feet and brushed himself off. "You next, Hal."
Hal climbed into the sill, lowered himself and dropped.
"All right," he called up to Chester.
Chester climbed to the sill.
"Here I come," he called; and just as he was about to lower himself a figure dashed suddenly into the room and seized him by the leg.
