"Have you mentioned the subject to Mr. B.?" he asked.

"Not yet; he is the nominal post master, it is true, but you have a far more intimate knowledge of the details of the office than he has. I have another reason for not speaking with him. I dislike to disturb his confidence until the establishment of strong proof renders it my duty to do so."

"You can speak to me with perfect plainness," said Carleton.

"I trust so," replied the Agent. "And I am sure you will do all you can to set me right, if I am going wrong. Nor will you, I am convinced, suffer me to injure an innocent person in your estimation. To come to the point, then, I wish you to open your inmost thoughts, and tell me if you regard it as possible that your fellow-clerk can be guilty of these depredations upon the mails."

"You shock me," said Carleton, not without emotion.

"Speak freely," continued the Agent.

"Why, I could almost as soon think of suspecting Mr. B. himself," exclaimed the other. "I believe Howard to be perfectly honest."

"Certainly, I know nothing to the contrary; and I sincerely hope your judgment is well founded. But," continued the Agent, "our public duty should not be altogether biassed by private opinion. You will not, therefore, fail to unite with me in tracing the embezzlements to their true source, no matter at whose door the blame may be laid."

"I will do all in my power," said Carleton. "Although I would be almost willing to pledge my own reputation that the losses have occurred outside of the office, I will use every exertion to discover any dereliction from duty that may come within my sphere of observation."

The Agent expressed his thanks for the clerk's ready promise of coöperation, and took his leave.
