“Hum! So it is—one of the kind made to represent ball cartridges,” mused Captain Putnam.

“I’ve got two of them!” exclaimed Pepper, and held them up. “My other one is all right,” he added.

“Two blanks and one good one,” said Jack. “That must have been just what I had!”

“Quartermaster Grenwood, can you explain this?” demanded Captain Putnam, sternly.

“N—no, sir. I—I am sure I didn’t deal out any of the blanks. I was very careful, sir.”

“Then how do you account for the blanks being in use?”

“I—I don’t account for it, sir. I am sure, though, I didn’t give them out.”

“You gave out all the ammunition, didn’t you?”

“Yes, sir.”

“Then you must have given out the blanks. It was very careless on your part.”
