"I think I must have heard all the men in the room talking about it at one time or another, Lieutenant, but the men are puzzled. They cannot account for the complete disappearance of the money."

"Are you keeping your eyes and ears open all the time, for any clue in the matter?"

"Yes, sir!" Noll answered. "And I shan't cease doing so until the whole mystery is cleaned up."

"Good! May I depend upon you, Corporal, to come to me, at any time, with any information that you think will help?"

"Yes, sir; and I thank you for the invitation to do so."

"If I believed Corporal Overton the guilty man, and could find evidence that would prove his guilt and have him bounced out of the service, then I'd do my whole duty," went on Lieutenant Prescott. "But I simply can't believe him guilty, and so I'm prepared to help him at any time when there's the slightest chance."

"May I tell Corporal Overton that, sir?" asked Noll eagerly.

"Yes; but caution him not to mention to others what I have said to you.

You are also at liberty to tell Overton that Captain Cortland is wholly convinced of his innocence, and so, I know, is Lieutenant Hampton. But some of the men in the company, and more especially in the squad room, are holding aloof from Corporal Overton, are they not?"

"I wouldn't exactly say that they are doing it in a mean way, sir; but of course soldiers hate thieves, and so the merest taint of a suspicion serves to make some of the men feel rather shy about having anything unnecessary to do with Corporal Overton."

"Too bad!" murmured Lieutenant Prescott. Then, in his usual official tone:

"That is all, Corporal Terry."

Noll saluted and left the inner office. Almost immediately afterward Lieutenant Prescott sauntered out.

In the meantime, Hal, after some brisk practice at wig-wagging, was on his way back to barracks with Sergeant Hupner.

"You're going to make a real signalman, one of these days, lad,"

remarked the sergeant, kindly. "You have the speed, and you don't lose any of the clearness of your signaling when you go fast."

"It's great work," smiled Corporal Hal. "Just for the moment it makes me almost sorry that I didn't enlist in the signal corps."

"The infantry is the real branch of the service--the real fighting arm,"

returned Sergeant Hupner.

"Yes; I know it, and that's the princ.i.p.al reason why I chose the infantry before enlisting."

Together the sergeant and his young corporal entered the barracks, stepping into their own squad room.

There the very first person they met was Private William Green, looking, still, as though he wanted to burst into tears. Green hadn't smiled once since meeting with his big loss.

"Good afternoon, Sergeant," was Green's greeting. He didn't seem to see Hal at all, a fact that the boyish soldier noted instantly. It cut like a whip to know that Green really suspected his young corporal.

Hal stepped down the length of the squad room. Some of the men greeted him, though none very enthusiastically.

Then Noll came in, drawing his chum aside and detailing the interview with Lieutenant Prescott.

That brightened Hal Overton a good deal. In the middle of the squad room some of the men were having a jolly time, and laughing heartily. Down at the further end of the room, near the door, mournful William Green kept by himself and grieved.

"It's certainly fine to know that one's officers trust him, anyway," Hal declared.

"Oh, this abominable business will all be cleared up before long," Noll Terry predicted cheerily.

"I'd like to believe you," Corporal Hal smiled wistfully.

"Wait and see!"

The merriment in the middle of the room was now going on at its height.

Private Clegg, who was an excellent storyteller, was relating one of his very very best, and it bore on Army life.

Hal and Noll took chairs at one of the writing tables.

A few minutes later a wild whoop sounded from Private William Green.

"I've got it! I've got it!" he yelled, dancing about like a crazy Indian.

"A bat in your belfry? Sure you've got it," yelled Private Clegg.

Sergeant Hupner had run over to where Green was dancing.

"I've got the money. It has come back to me," sang William Green joyously.

In an instant there was a curiosity-inspired rush that every man in the room shared.

Private Green now held high aloft over his head a long envelope whose bulkiness everyone else could see.

"It's the money!" he gasped, chokingly.

"Every man in the room but Green fall in!" roared Sergeant Hupner's voice. "Corporal Terry, take charge of the formation!"

There was a queer, strained hush in the room for the next few moments.

Hardly anything was heard but the low breathing of the men, or the few crisp, quiet words of Corporal Noll as he made the men dress their alignment on Corporal Hal, who stood at the right of the line.

"Hold your men so," nodded Sergeant Hupner tersely. "Now, Green, are you sure you have all your money back?"

"I--I hope so," faltered Green. "The envelope is bulky enough."

"Put it on your cot and let me see it," ordered Hupner.

Green had already broken the flap of the envelope, revealing the edges of a considerable thickness of banknotes.

"Why, there's a note here with the bills," proclaimed the excited soldier.

"What does the note say?"

"It says 'Friend, you'll find all your money here except twenty dollars that I spent. Meant to keep it all, but found stolen money brings no pleasure. Hope you'll forgive me.'"

"What does the writing look like?" demanded Sergeant Hupner.
