“Well, he did most of the arguing,” said the other, with a faint smile. “He’s so blamed used to having his own way that if any one doesn’t do just as he wants, he gets mad.

“I suppose I should make allowances for him, because he has plenty to worry him,” went on Thompson. “Some of those Wall Street manipulators are a ruthless bunch, and when they aren’t busy taking money from an innocent public, they stage some battles between each other. Mr. Salper has an idea that a bunch of them are trying to swing the market against him while he’s up here, and he seems to think that this is a public radio station, with nothing to do but send and receive messages for him all day. I’m working for Uncle Sam, not for him.”

“Oh, well, don’t let him get you all stirred up, anyway,” said Bob. “He doesn’t mean half of what he says. He was real decent last night while we were giving our concert.”

“What do you mean, concert?” asked the wireless man. “Are you in the entertainment game now?”

“Something like that,” answered Bob, grinning, and then he told the operator about the concert of the previous evening.

“That’s fine,” said Thompson heartily, when he had finished. “That was a good idea, to use a regular aerial instead of the loop. It certainly catches a lot more.”

“Yes, but the loop is mighty handy, just the same,” remarked Joe. “Especially in a portable set. You can set it up in no time.”

“Oh, it’s handy, there’s no doubt of that,” admitted the young wireless man. “I wish I had been there for the concert. I heard most of it here, but it must have been fun to watch the faces of the audience when you started in.”

“It was,” laughed Herb. “I think that some of them imagined we had a phonograph hidden somewhere because after the concert was over a number of them looked all around the set as though they were hunting for something suspicious.”

“Likely enough,” agreed Thompson. “Some people are mighty hard to convince.”
