The Union Foundry employs eighty-four hands the "year round," and consumes six hundred tons of metal. KENTUCKY BRASS FOUNDRY AND MACHINE SHOP. LAWSON & FRANK. MANUFACTURERS OF STEAM AND FIRE ENGINES, BAGGING MACHINERY, &C. Main street, near Ninth. This well known Brass Foundry, now in the fifteenth year of its existence, is another of those factories which are ornaments to the city. It has never attempted the heavy steamboat castings, rather choosing the lighter machinery; and the reputation of the establishment is derived chiefly from the excellent finish and completeness of the work turned out. The most complex machinery is carefully and accurately made and fitted together. All work requiring nicety of construction and careful attention to detail, is here manufactured, and in a manner which has always given entire satisfaction. Every article is made under the immediate supervision of the proprietors, who are practical workmen and whose past reputation is a sure guarantee for the quality of every piece of work. The Fire Engines, and machinery for Hemp manufacture made at this establishment are deservedly celebrated.-- Some of the most effective fire engines of this city and vicinity, have been constructed at this foundry. The Brass work made there is also creditable. From thirty-five to forty hands are employed constantly; the business, unlike that of most foundries, being equally good at all seasons of the year. HYDRAULIC FOUNDRY. TEVIS & BARBAROUX, MANUFACTURERS OF CAST IRON SCREW PIPE, IRON RAILING, ORNAMENTAL CASTINGS, PATENT PUMPS, &C., &C. WASHINGTON ST. COR. FLOYD.
