“ ‘By the way, Mr. Plunket, I have mislaid my memorandum book that has the formula of my tonic in it and I want to have a bottle or two prepared this morning. If you have the one I gave you I’d like to make a copy of it while you are here.’

“I must have looked too anxious, for he looked at me for a few minutes and then broke out into a laugh.

“ ‘By Jiminy,’ he said, ‘I don’t believe you’ve got a copy of it anywheres. I believe you just happend to hit on the right thing and you don’t remember what it was. I ain’t half as green as I look. That hair grower is worth a fortune, and a big one, too. I think I’ll just keep my recipe and get somebody to put the stuff up and sell it.’

“He started out, and I called him into the back room and talked to him half an hour.

“I finally made a trade with him and bought the formula back for $250 cash. I went up to the bank and got the money which I had there saving up to build a house. He then gave me back the recipe I had given him and signed a paper relinquishing all rights to it. He also agreed to sign a testimonial about the stuff having made his hair grow out in two weeks.”

The barber began to look gloomy and ran his fingers inside the Post Man’s shirt collar, tearing out the button hole, and the collar button flew out the door across the sidewalk into the gutter.

“I went to work next day,” said the barber, “and filed application at Washington for a patent on my tonic and arranged with a big drug firm in Houston to put it on the market for me. I had a million dollars in sight. I fixed up a room where I mixed the tonic—for I wouldn’t let the druggists or anybody else know what was in it—and then the druggists bottled and labeled it.

“I quit working in the shop and put all my time into my tonic.

“Mr. Plunket came into the shop once or twice within the next two weeks and his hair was still growing finely. Pretty soon I had about $200 worth of the tonic ready for the market, and Mr. Plunket was to come in town on Saturday and give me his testimonial to print on advertising dodgers and circulars with which I was going to flood the country.

“I was waiting in the room where I mixed my tonic about 11 o’clock Saturday when the door opened and Mr. Plunket came in. He was very much excited and very angry.
