Then out from the semi-darkness at the starboard yard-arm, there came a curse from Jaskett, followed almost immediately by a noise of something vibrating.

"What's up?" shouted the Second Mate. "What's up, Jaskett?"

"It's ther foot-rope, Sir-r-r!" he drew out the last word into a sort of gasp.

The Second Mate bent quickly, with the lantern. I craned round the after side of the top-mast, and looked.

"What is the matter, Mr. Tulipson?" I heard the Old Man singing out.

Out on the yard-arm, Jaskett began to shout for help, and then, all at once, in the light from the Second Mate's lantern, I saw that the starboard foot-rope on the upper topsail yard was being violently shaken—savagely shaken, is perhaps a better word. And then, almost in the same instant, the Second Mate shifted the lantern from his right to his left hand. He put the right into his pocket and brought out his gun with a jerk. He extended his hand and arm, as though pointing at something a little below the yard. Then a quick flash spat out across the shadows, followed immediately by a sharp, ringing crack. In the same moment, I saw that the foot-rope ceased to shake.

"Light your flare! Light your flare, Jaskett!" the Second shouted. "Be smart now!"

Out at the yard-arm there came a splutter of a match, and then, straightaway, a great spurt of fire as the flare took light.

"That's better, Jaskett. You're all right now!" the Second Mate called out to him.

"What was it, Mr. Tulipson?" I heard the Skipper ask.
