"Jump ashore, both of you, and take the painter with you, my men," said the mate, when the boat stuck about six feet from the top of the ledge.

The two sailors waded to the highest part of the reef, and began to haul in on the painter; but they could not get it anything less than three feet from the rock.

"We can't get the boat any nearer, Mr. Passford; but you are a vigorous young man, and you can easily leap to the rock," said Mr. Dawbin.

"Do you think you could leap to the ledge?" asked Christy, looking him sharp in the eye.

"I know I could."

"Let me see you try it, Mr. Dawbin," replied Christy, with his right hand on his revolver.

"Come, come! Mr. Passford. No fooling. I have no time to spare," growled the mate.

"I am not fooling. As you consider it no hardship to pass a few hours on that rock, I am going to trouble you to take my place there."

"No nonsense! I am not to be trifled with!"

"Neither am I," added the prisoner, as he drew out his weapon, and aimed it at the head of the mate. "You can take your choice between the rock and a ball from my revolver, Mr. Dawbin."
