We now proceed to examine a more interesting topic, viz., the rise and progress of the flint-glass business in the West. We have shown that most of the workmen, on the breaking up of the glass-works in Fredericktown, migrated to Pittsburg, attracted there, doubtless, by the coal mines. Some of these persons were successful in establishing the manufacture of window-glass, while a portion of the workmen, in the spring of the year 1808, attempted to establish a flint-glass manufactory upon part of the premises now occupied by Bakewell & Pears, extensive flint-glass manufacturers. The persons engaged in the enterprise, however, were deficient, both in the requisite knowledge and capital; the effort proved abortive, the parties quarrelled, and the establishment, in an incomplete condition, was offered for sale. In the August following, a Mr. Bakewell and his friend, Mr. Page, being on a visit to Pittsburg, were induced to purchase the concern, under the representation of one of the owners that he possessed the information and skill requisite for the proper pursuit of the business, having been engaged (as he stated) in the business before he left England. Mr. Bakewell had scarcely entered upon his new pursuit before he discovered that the qualification of the person alluded to had been entirely misrepresented, and that to succeed he must rely upon his own experience and diligence in the attainment of the peculiar knowledge indispensable to the success of his undertaking. In this the fortune of his family and friend were, of course, deeply involved, and he therefore set himself to the accomplishment of his task most manfully. Those only who have practical experience of the character of the undertaking can fully appreciate the various and almost insurmountable difficulties to be encountered and overcome before success could be attained. His first difficulty arose from want of skill in the workmen, and the inferiority of the materials employed in the manufacture of flint-glass. So little were the resources of the West developed at that day, that Mr. Bakewell had to procure his pearlash and red lead from Philadelphia, the pot clay from Burlington, N.J.,--the whole being transported over the mountains in wagons to Pittsburg. The only sand then known was the yellow kind, obtained in the vicinity, and used at this time only for window-glass. For many years Mr. Bakewell obtained the saltpetre needed from the caves of Kentucky, in a crude state, which article he was obliged to purify, until the period of 1815, when the required supply was obtained from Calcutta.
