I possess a billiard secret which can be valuable to the Dooley sept, after I shall have conferred it upon Dooley--for a consideration. It is a discovery which I made by accident, thirty-eight years ago, in my father-in-law's house in Elmira. There was a scarred and battered and ancient billiard-table in the garret, and along with it a peck of checked and chipped balls, and a rackful of crooked and headless cues. I played solitaire up there every day with that difficult outfit. The table was not level, but slanted sharply to the southeast; there wasn't a ball that was round, or would complete the journey you started it on, but would always get tired and stop half-way and settle, with a jolty wabble, to a standstill on its chipped side. I tried making counts with four balls, but found it difficult and discouraging, so I added a fifth ball, then a sixth, then a seventh, and kept on adding until at last I had twelve balls on the table and a thirteenth to play with. My game was caroms--caroms solely--caroms plain, or caroms with cushion to help--anything that could furnish a count. In the course of time I found to my astonishment that I was never able to run fifteen, under any circumstances. By huddling the balls advantageously in the beginning, I could now and then coax fourteen out of them, but I couldn't reach fifteen by either luck or skill. Sometimes the balls would get scattered into difficult positions and defeat me in that way; sometimes if I managed to keep them together, I would freeze; and always when I froze, and had to play away from the contact, there was sure to be nothing to play at but a wide and uninhabited vacancy. One day Mr. Dalton called on my brother-in-law, on a matter of business, and I was asked if I could entertain him awhile, until my brother-in-law should finish an engagement with another gentleman. I said I could, and took him up to the billiard-table. I had played with him many times at the club, and knew that he could play billiards tolerably well--only tolerably well--but not any better than I could. He and I were just a match. He didn't know our table; he didn't know those balls; he didn't know those warped and headless cues; he didn't know the southeastern slant of the table, and how to allow for it. I judged it would be safe and profitable to offer him a bet on my scheme. I emptied the avalanche of thirteen balls on the table and said: "Take a ball and begin, Mr. Dalton. How many can you run with an outlay like that?" He said, with the half-affronted air of a mathematician who has been asked how much of the multiplication table he can recite without a break: "I suppose a million--eight hundred thousand, anyway." I said "You shall hove the privilege of placing the balls to suit yourself, and I want to bet you a dollar that you can't run fifteen."
