The few workmen then in the country were not well instructed in the making of glass articles, after the glass was prepared, to which was added the great evil (which has too usually prevailed among the imported workmen) of a determination to prevent the instruction of apprentices by the most arbitrary and unjust means, and, so far as it was in their power, endeavoring to prevent competition, by not only controlling the hours of work, but the quantity of manufacture; in fact, doing the least amount of work possible for the largest amount of pay that could be coerced from the proprietors. Experience, however, showed Mr. Bakewell how to construct his furnaces, or, at least, to improve on the old; and he discovered better materials in his immediate vicinity, and succeeded in making purer glass than he had before made. The oppressive acts of the workmen, in the mean time, compelled Mr. Bakewell to resort to England for new workmen, at a time when the prohibitory laws there in regard to mechanics leaving England were in full force,--an undertaking requiring great secrecy, and at the risk of long imprisonment if detected. Such were some of the embarrassing circumstances with which Mr. Bakewell had to contend. Of the full force and extent of these, those only can conceive who have been under like necessities and circumstances. But a brighter day was dawning upon his exertions, and at length his arduous and untiring labor was crowned with the desired success. Good clay was procured from Holland, and purer materials discovered; competent workmen were either imported or instructed, and the flint-glass manufacture was firmly established at Pittsburg. From this first establishment there originated, in a few years, many other glass-works, erected chiefly by persons who had acquired the art with Mr. Bakewell, or had obtained the requisite means while in his employ. We may well consider Mr. Bakewell as the father of the flint-glass business in this country; for he commenced the work in 1808, and by untiring efforts and industry brought it to a successful issue. For the skill, judgment, labor, and perseverance devoted by him to the progress of the art, he truly merits the "Artium Magister" so often bestowed on those least worthy of its dignity and honor. Theory in Science too often receives the meed which practical progress in its walks so richly deserves. Mr. Bakewell lived to realize an ample fortune as the fruit of his industry, and his sons still carry on a profitable business on the premises originally occupied by their father. By father and sons this has covered a space of forty-four years, a length of time rarely finding a business in the same family in America. May the factory be always occupied and conducted by a Bakewell.
