The following list of diplomas, medals, &c., which have been awarded at different times to the hams cured by Mr. Duffield, will corroborate this opinion. By Ohio Mechanics' Institute, in 1844; by Hamilton County Agricultural Society, in 1846; by Ohio State Fair, held in Cincinnati, in 1850; by The London Industrial Exhibition, and World's Fair Prize Medal, in 1850. We are proud of Mr. D.'s reputation, and glad to be able to say that Louisville has _the largest ham curing establishment in the world_. A. McBRIDE, MANUFACTURER OF PLANES AND EDGE TOOLS, No. 69 Third Street. The manufacture of Planes and Edge-Tools in Louisville is not and has not been considered a very prominent branch of trade. It is well known that the skillful manufacture of these articles has long been a difficulty hard to overcome. Mr. McBride, who has been a practical workman with the plane, has successfully combatted all the difficulties in the way of producing a perfect article. Wherever the tools from this factory have been used, they have achieved that most difficult of results, the entire approbation of the mechanic. Mr. B.'s business is one of those the steady growth of which indicates real merit and ultimate success. Every article produced is made by the hands of skillful workmen, and under the immediate eye of the proprietor; hence all may be sure of procuring a far more valuable article than can be had from the steam factories. Mr. McBride has in addition to his manufactory, a fine stock of Hardware and Cutlery. HENRY HUNTER, GLASS CUTTING ESTABLISHMENT, No. 69 Third Street. This useful establishment is one of those minor factories which are indispensible to a great city. Necessary of small extent as compared with many other branches of manufacture, it is yet an important and useful concern. Mr. Hunter is the foreman of his own factory, and is a thorough and accomplished workman. It is at his shop that those elegant cuttings on tinted and white glass, which adorn the windows of our southern steamboats, and add so much to their magnificence, are done. In this department of his business he is without a rival in the city and, it is believed, in the West. Beside this, Mr. H. is a fitter of glasses for jeweller's work, such as rings, breast-pins, miniatures, &c. He also replaces parts of broken sets of glass and performs, in a superior manner, all the work done at the glass cutters. A good stock of cut glass-ware is also to be found at this factory.
