H^XITH, r»i-ox>rietoi and jVraiiiifactixrer, SALEM, Mass. These Bars are acknowledged by all practical engineers to be superior in every respect to all other Bars in use. We claim a superiority over all other Bars on the following points, Durability. By making the ribs with a doublecurve the Bar is not so liable to be strained and injured by unequal heating as it would if the Bars were straight, or evenof a single curve. If one side of the bar becomes heated first it yields on the opposite side, tiius preventing any injury tothe Bar, such as warping, twisting, cracking, &c., which would otherwise result frsm the sudden expansion of one sidewithout suitable provisions for a corresponding bending on the other side. They will last one-third longer than anyother bar in use. 2d.—Strength. Their peculiar construction and the distribution of the metal renders them the strongest und
