As soon as he realized the importance of his discovery Captain Moore went below.

A corporal's guard was called out and sent over to the stable, and when Bicker and Drossdell came below they were placed under arrest.

"What's this for?" demanded Bicker, putting on a bold front. Drossdell had nothing to say, and trembled so he could scarcely stand.

"You know well enough, Bicker," answered Captain Moore sternly.

"No, I don't. I haven't done anything wrong, captain."

"March them to the guardhouse," was all the young commander said, and the two were promptly marched away.

As may be surmised, the moment the evildoers were alone each accused the other of having done something to bring on exposure.

Captain Moore knew his men well, and presently he sent for Drossdell and interviewed the soldier in private.

"I am sorry to see you in such trouble as this, Drossdell," he said. "I thought you were a better soldier."

"I haven't done anything, captain."
