Excerpt from A Manual of Useful Information and Tables Appertaining to the Use of Structural Steel, as Manufactured by the Passaic Rolling Mill Co: Paterson, New Jersey (New York Office, 45 Broadway;), For Engineers, Architects and Builders The tables, with a few exceptions, were computed expressly for this work, and many of them are original in both matter and form. The author hopes that they will be found to possess the qualities of accuracy and reliability. Such of the tables as were not calculated for this work were obtained from works of presumably independent origin, which were compared for the detection of errors. The tables of the weights and ultimate strengths of materi als have been compiled by comparison of all the available data on the subject. N o attempt has been made to encumber the work with abridgments of mathematical tables, as such tables, to be of value, must be very extended and complete. Only such mat ter is given as the author has found to be of service in his own practice. About the Publisher Forgotten Books publishes hundreds of thousands of rare and classic books.
