"Are you sure of that?"

"I ought to be. These postals—there were a lot of them—were stuffed in through the slot in the door some time during the night. It must have been late, for we didn't close until nearly twelve o'clock. The postals were all on the floor when I opened up the place this morning."

"Did you read any of the postals?" asked Steve innocently.

"Oh, yes, I always read postals. Don't have much of anything else to do part of the day, you know," replied the postmaster in a matter-of-fact tone. "Why, what's in the wind? No trouble about it, is there?"

"There may be," replied the lad mysteriously. "But if you will state the facts when called upon to do so, there will be no trouble so far as you are concerned. Will you do that?"

"Yes; I'll do that, all right. It won't violate any regulation of the department that I know of."

"Thank you. Say nothing to anyone of what I have asked you to-night, please."

"I think I have got something on our friend, the walking delegate, now," muttered the lad triumphantly, as he made his way toward home. He had gone but a short distance when he met five of the members of the union, all dressed in their best, hurrying along the street.

Steve halted and peered at them suspiciously.

"Hello, where are you fellows going?" he demanded.
