"The reason is, young man," said Barlow grimly, "that, if I contract for twenty-five thousand gallons I can get a much better price than if I contract for, let us say, half that amount. Also, I don't think I could sell it all from my store. The garage is near the center of the town; so that, unless some one is selling gas the other side of the garage man, his would be the first station reached by people entering the town from that side. Consequently, he would get half the trade. Now, he runs a competing gas station, so I couldn't possibly work with him. Hence I am willing to back you on this, because it won't cost me anything. And even if I make half a cent on all you use, it doesn't cost you anything, because you buy at even less than you would buy a smaller quantity direct from the Starling people." Pretty shrewd reasoning, wasn't it? When I got home, I talked it over with the Mater. She said, "But, Dawson, my boy, if people were to stop at your store and buy some gasoline" (the Mater is very old-fashioned, and doesn't believe in clipping words and thinks it vulgar to call it "gas"), "would not some of the owners of the automobiles want supplies of different kinds, and if they want supplies, aren't they likely to go to the garage for them, and then buy their gasoline there? Now, Mr. Martin is a very nice gentleman, and you don't want to do anything that will hurt him--" "Unless I can materially help myself!" The Mater shook her head. "These new-fangled business ideas are strange to me." But what the Mater said made me think; so that, in the morning, I went to Barlow and told him I would really like to go into the gasoline business, but that, if I did, I would have to go into the automobile accessory business also. "When any one is buying gas," I said, "they are good prospects for oil and accessories generally. If a man has a break-down, why that's a job for the garage; but, if he wants only supplies, I don't see why he couldn't get them from a hardware store just as well as anywhere else. Now, Mr. Barlow, I'll gladly pay you that half a cent on the gas, and I'll push it for you all I can, but I feel that I would have to sell automobile accessories too. So, if you will buy accessories also, and let me have a small stock, on sale or return, for just three months, I will pay you a small percentage of profit for your help, and guarantee, at the end of the three months, to carry my own automobile department without any help from you." He tapped his counter slowly with his pencil for a few moments.
