and the groove will do the rest; it will slam the ball against the northeast curve of the head pin every time, and nothing can save the ten from going down." It was true. The boys made the experiment and they found that there was no art that could send a ball down that alley and fail to score a ten-strike with it. When I had told those boys that I knew nothing about that game I was speaking only the truth; but it was ever thus, all through my life: whenever I have diverged from custom and principle and uttered a truth, the rule has been that the hearer hadn't strength of mind enough to believe it. [Sidenote: (1873.)] A quarter of a century ago I arrived in London to lecture a few weeks under the management of George Dolby, who had conducted the Dickens readings in America five or six years before. He took me to the Albemarle and fed me, and in the course of the dinner he enlarged a good deal, and with great satisfaction, upon his reputation as a player of fifteen-ball pool, and when he learned by my testimony that I had never seen the game played, and knew nothing of the art of pocketing balls, he enlarged more and more, and still more, and kept on enlarging, until I recognized that I was either in the presence of the very father of fifteen-ball pool or in the presence of his most immediate descendant. At the end of the dinner Dolby was eager to introduce me to the game and show me what he could do. We adjourned to the billiard-room and he framed the balls in a flat pyramid and told me to fire at the apex ball and then go on and do what I could toward pocketing the fifteen, after which he would take the cue and show me what a past-master of the game could do with those balls. I did as required. I began with the diffidence proper to my ignorant estate, and when I had finished my inning all the balls were in the pockets and Dolby was burying me under a volcanic irruption of acid sarcasms. So I was a liar in Dolby's belief. He thought he had been sold, and at a cheap rate; but he divided his sarcasms quite fairly and quite equally between the two of us. He was full of ironical admiration of his childishness and innocence in letting a wandering and characterless and scandalous American load him up with deceptions of so transparent a character that they ought not to have deceived the house cat. On the other hand, he was remorselessly severe upon me for beguiling him, by studied and discreditable artifice, into bragging and boasting about his poor game in the presence of a professional expert disguised in lies and frauds, who could empty more balls in billiard pockets in an hour than he could empty into a basket in a day. In the matter of fifteen-ball pool I never got Dolby's confidence wholly back, though I got it in other ways, and kept it until his death. I have played that game a number of times since, but that first time was the only time in my life that I have ever pocketed all the fifteen in a single inning. [Sidenote: (1876.)]
