"We've got to git hold of those cartridges," he said, after a long-pause. "Carlsen had 'em planted somewhere, an' it's likely in his room. Best thing to do is to chuck 'em overboard. Cheaper to dump the cartridges an' shells than the rifles an' shotguns.

"You see," he went on, "Deming ain't quit. That's one thing with a man who's streaked with yeller, when he gits licked in the open an' knows he's licked proper, he tries to git even underhanded. He knows jest as well as I do that Carlsen was lyin' that time about there bein' no more shells. O' course the skipper may have stowed 'em away, but I doubt it. An' jest so long as he thinks there's a chance of gittin' at 'em, he'll figger on turning' the tables some day. An' he'll be workin' the rest of 'em up to the job."

"They can't do much without a navigator," suggested Rainey.

"Mebbe they figger a man'll do a lot o' things he don't want to with a rifle barrel stuck in his neck or the small of his back," said Lund grimly. "It's a good persuader. Might even have some influence on me. Then ag'in it might not."

"Where is the magazine?" asked Rainey.

"In the little room aft o' the galley. We'll look there first. Come on."

"How about keys? Carlsen's must have been in his pockets. I didn't see them when I was hunting the morphine. We can't go in there." Rainey made a motion toward the skipper's room. Lund chuckled.

"I had my keys to the safe an' the magazine when I was aboard last trip," he said. "They was with me when we went on the ice. An' I hung on to 'em. Allus thought I might have a chance to use 'em ag'in."

The strong room of the Karluk was a narrow compartment, heavily partitioned off from the galley and the corridor. There was a lamp there, and Rainey lit it while Lund closed the door behind them. The magazine was an iron chest fastened to the floor and the side of the vessel with two padlocks, opened by different keys. It was quite empty.

"Thorough man, Carlsen," said Lund. "Prepared for a show-down, if necessary. Might have put 'em in the safe. Wonder if he changed the combination? I bet Simms didn't, year in an' out."
