Without another word, Jack went to work.

"Nothing wrong here, Mr. Gifford," he said in a minute. "Where are the screw-driver, and the monkey-wrench, and an oil-can?"

"Well, well!" exclaimed Mr. Gifford, as he sent a man for the tools.

"Do you think you can do it?"

Jack said nothing aloud, but he told himself:

"Why, it's a smaller size but like the one in the _Eagle_ office. They get out of order easily, but then it's easy to regulate them."

"You do know something," said Mr. Gifford, laughing, a few minutes later, when Jack said to him:

"She'll do now."

"She won't do very well," added Mr. Gifford, shaking his head. "That engine never was exactly the thing. It lacks power."

"It may be the pulley-belt's too loose," said Jack, after studying the mechanism for a moment.

"I'll send for a man to fix it, then."

"No, you needn't," said Jack. "I can tighten it so she'll run all the machinery you have. May I have an awl?"

"Of course," said Mr. Gifford. "Put it to rights. There's plenty of coffee waiting to be ground."

Jack went to work at the loose belt.

"He's a bright fellow," said Mr. Gifford to his head-clerk. "If we wanted another boy--but we don't."

"Too many now," was the short, decisive reply.

It was not long before the machinery began to move.

"Good!" said Mr. Gifford. "I almost wish I had something more for you to do, but I really haven't. If you could run that good-for-nothing old printing-press--"

"Printing-press?" exclaimed Jack.

"Over in the other window," said Mr. Gifford. "We thought of printing all our own circulars, cards, and paper bags. But it's a failure, unless we should hire a regular printer. We shall have to, I suppose.

If you were a printer, now."

"I've worked at a press," said Jack. "I'm something of a printer. I'm sure I can do that work. It's like a press I used to run when I worked in that business."

Jack at once went to the show-window.

"An 'Alligator' press," he said, "like the one in the _Standard_ office. It ought to be oiled, though. It needs adjusting, too. No wonder it would not work. I can make it go."

The business of the store was beginning. Steam was up in the engine, and the coffee-mills were grinding merrily. Mr. Gifford and all his clerks were busied with other matters, and Jack was left to tinker away at the Alligator press. "She's ready to run. I'll start her," he said at last.

He took an impression of the form of type that was in the press and read it.

"I see," he said. "They print that on their paper bags for an advertis.e.m.e.nt. I'll show it to Mr. Gifford. There are plenty of blank ones lying around here, all ready to print."

He walked up to the desk and handed in the proof, asking:

"Is that all right?"

"No," said Mr. Gifford. "We let our stock of bags run down because the name of the firm was changed. I want to add several things. I'll send for somebody to have the proof corrections made."

"You needn't," said Jack. "Tell me what you want. Any boy who's ever worked in a newspaper office can do a little thing like that."

"How do you come to know so much about machinery?" asked Mr. Gifford, trying not to laugh.

"Oh," said Jack, "I was brought up a blacksmith, but I've worked at other trades, and it was easy enough to adjust those things."

"That's what you've been up to is it?" said Mr. Gifford. "I saw you hammering and filing, and I wondered what you'd accomplished. I want the new paper bags to be,"--and he told Jack what changes were required, and added:

"Then, of course, I shall need some circulars--three kinds--and some cards."

"That press will run over a thousand an hour when it's geared right.

You'll see," said Jack, positively.

"Well, here's a true Jack-at-all-trades!" exclaimed Mr. Gifford, opening his eyes. "I begin to wish we had a place for you!"

It was nearly noon before Jack had another sample of printing ready to show. There was a good supply of type, to be sure, but he was not much of a printer, and type-setting did not come easily to him. He worked almost desperately, however, and meanwhile his brains were as busy as the coffee-mills. He succeeded finally, and it was time, for a salesman was just reporting:

"Mr. Gifford, we're out of paper bags."

"We must have some right away," said Mr. Gifford. "I wish that youngster really knew how to print them. He's tinkering at it over there."

"Is that right?" asked Jack only a second later, holding out a printed bag.

"Why, yes, that's the thing. Go ahead," said the surprised coffee-dealer. "I thought you'd failed this time."

"I'll run off a lot," said Jack, "and then I'll go out and get something to eat."

"No, you won't," said Mr. Gifford promptly. "No going out, during business hours, in _this_ house. I'll have a luncheon brought to you.

I'll try you to-day, anyhow."

Back went Jack without another word, but he thought silently, "That saves me ten cents."

The Alligator press was started, and Jack fed it with the blank paper bags the salesmen needed, and he began to feel happy. He was even happier when his luncheon was brought; for the firm of Gifford & Company saw that their employees fared well.

"I declare!" said Jack to himself, "it's the first full meal I've had since last week Wednesday! I was starved."

On went the press, and the young pressman sat doggedly at his task; but he was all the while watching things in the store and hearing whatever there was to hear.

"I know their prices pretty well," he thought. "Most of the things are marked--ever so much lower than Crofield prices, too."

He had piles of printed bags of different sizes ready for use, now lying around him.
