But Harvey refused to respond to frivolity.

"It's never happened before because I never let it happen before," he replied stiffly. "There have been mistakes like that, and worse, in almost every report we've filed. I've cut them out. Now, Mr. Fox, I don't have much to say, but I'd rather do a thing myself than do it over after somebody else. We've got a good deal to keep track of in this office, as you know, without having to go over everybody else's work too."

"H'm," said Fox, thoughtfully. Then after a moment, "I'll see about it."

Harvey went back to the outer office, and Fox turned at once to Bob.

"Well, how is it?" he asked. "How did it happen?"

"I don't know," replied Bob. "I'm trying, Mr. Fox. Don't think it isn't that. But it's new to me, and I can't seem to get the hang of it right away."

"I see. How long you been here?"

"A little over four months."

Fox swung back in his chair leisurely.

"You must see you're not fair to Harvey," he announced. "That man carries the details of four businesses in his head, he practically does the clerical work for them all, and he never seems to hurry. Also, he can put his hand without hesitation on any one of these documents," he waved his hand about the room. "I can't."
