The furnace built by Mr. Bakewell in 1808 contained only six pots, twenty inches in diameter, which were replaced in 1810 by a ten-pot furnace of a larger capacity, and in 1814 another furnace was added to the works, of like capacity. In 1809 another concern sprung up, and carried on the business on a limited scale; in 1812 another succeeded, making three concerns carrying on the business; and in 1810 another company was formed, but failed in a few years. There are now in Pittsburg nine concerns manufacturing flint-glass, running thirteen furnaces and one hundred and five pots. There are also three concerns at Wheeling, running five furnaces and forty-five pots. There are also at Wellsville, Steubenville, and Cincinnati one or two factories each, besides several manufactories for green glass jars, and one for the making of porter bottles; one also for mineral-water bottles. The first glass-cutting works were opened in 1809 by a German of the name of Echbaum, who had settled in Pittsburg some years previously. Mr. Bakewell also carried on glass-cutting, and among his workmen was an Englishman who had served as a soldier in Canada, being taken as a prisoner in one of the battles on the Lakes in 1813. He proved not only a good glass-cutter, but an excellent mechanic, in various branches; but still a dissipated and idle man, and of course of but little service in the manufactory. One of the amusing incidents connected with the manufacture occurred when General Clark (then Governor of Missouri) took a party of Osage Chiefs to Washington. On their way they visited Bakewell's Glass-Works, and their attention was greatly excited; they watched with great curiosity the process of making various articles, and the mode of affixing the handle to a glass pitcher quite disturbed the equanimity of the head chief, who, after shaking hands with the workmen, said, through the interpreter, "That man must have had some intercourse with the Great Spirit." The following, from Sigma's pen, shows a decanter-stopper can be made to point a moral or illustrate a satire:--"Mr. Flint, in his 'Ten Years in the Valley of the Mississippi,' tells a pleasant story of an Indian who told him he had _big diamond_, for which he had given trader _much beaver_. A time was appointed, and Mr. Flint visited the wigwam to examine the diamond, which, after considerable mystery, was brought forth from its place of concealment, and proved to be a broken glass decanter-stopper. When an individual, eminent for his talents and learning, has been justly decorated with the degree of LL.D., and finds the same mark of distinction bestowed upon others who are remarkable for neither, he cannot fail to perceive an amusing resemblance between his diploma and Kunkerpot's diamond." IMITATION OF MUSLIN-GLASS. Here is a simple and ingenious means of giving to glass the appearance of delicately wrought muslin:--
