Read it through once

"But look here, Dave," said Tom, "you used to tell people's fortunes, too, when you took their finger-marks. Dave's just an all-round genius--a genius of the first water, gentlemen; a great scientist running to seed here in this village, a prophet with the kind of honor that prophets generally get at home--for here they don't give shucks for his scientifics, and they call his skull a notion-factory--hey, Dave, ain't it so? But never mind; he'll make his mark some day--finger-mark, you know, he-he! But really, you want to let him take a shy at your palms once; it's worth twice the price of admission or your money's returned at the door. Why, he'll read your wrinkles as easy as a book, and not only tell you fifty or sixty things that's going to happen to you, but fifty or sixty thousand that ain't. Come, Dave, show the gentlemen what an inspired Jack-at-all-science we've got in this town, and don't know it."
