"Catch hold, Jessop," he said, which I did.

Then he pulled the blue light from his pocket, and as he was doing so, I saw the Second peek round the back side of the mast at him. Evidently, in the uncertain light, he must have mistaken the Skipper's action; for, all at once, he shouted out in a frightened voice:

"Don't shoot, Sir! For God's sake, don't shoot!"

"Shoot be damned!" exclaimed the Old Man. "Watch!"

He pulled off the cap of the light.

"There's two of them, Sir," I called again to him.

"What!" he said in a loud voice, and at the same instant he rubbed the end of the light across the cap, and it burst into fire.

He held it up so that it lit the royal yard like day, and straightway, a couple of shapes dropped silently from the royal on to the t'gallant yard. At the same moment, the humped Something, midway out upon the yard, rose up. It ran in to the mast, and I lost sight of it.

"God!" I heard the Skipper gasp, and he fumbled in his side pocket.

I saw the two figures which had dropped on to the t'gallant, run swiftly along the yard—one to the starboard and the other to the port yard-arms.
