won't hurt it; and you can paint a steam-boiler with it, and heat won't. You can cover a brick wall with it, or a railroad car, or the deck of a steamboat, and you can't do a better thing for either." "Never tried it on the human conscience, I suppose," suggested Bartley. "No, sir," replied Lapham gravely. "I guess you want to keep that as free from paint as you can, if you want much use of it. I never cared to try any of it on mine." Lapham suddenly lifted his bulk up out of his swivel-chair, and led the way out into the wareroom beyond the office partitions, where rows and ranks of casks, barrels, and kegs stretched dimly back to the rear of the building, and diffused an honest, clean, wholesome smell of oil and paint. They were labelled and branded as containing each so many pounds of Lapham's Mineral Paint, and each bore the mystic devices, N.L.f. 1835--S.L.t. 1855. "There!" said Lapham, kicking one of the largest casks with the toe of his boot, "that's about our biggest package; and here," he added, laying his hand affectionately on the head of a very small keg, as if it were the head of a child, which it resembled in size, "this is the smallest. We used to put the paint on the market dry, but now we grind every ounce of it in oil--very best quality of linseed oil--and warrant it. We find it gives more satisfaction. Now, come back to the office, and I'll show you our fancy brands." It was very cool and pleasant in that dim wareroom, with the rafters showing overhead in a cloudy perspective, and darkening away into the perpetual twilight at the rear of the building; and Bartley had found an agreeable seat on the head of a half-barrel of the paint, which he was reluctant to leave. But he rose and followed the vigorous lead of Lapham back to the office, where the sun of a long summer afternoon was just beginning to glare in at the window. On shelves opposite Lapham's desk were tin cans of various sizes, arranged in tapering cylinders, and showing, in a pattern diminishing toward the top, the same label borne by the casks and barrels in the wareroom. Lapham merely waved his hand toward these; but when Bartley, after a comprehensive glance at them, gave his whole attention to a row of clean, smooth jars, where different tints of the paint showed through flawless glass, Lapham smiled, and waited in pleased expectation. "Hello!" said Bartley. "That's pretty!" "Yes," assented Lapham, "it is rather nice. It's our latest thing, and we find it takes with customers first-rate. Look here!" he said,
