9 July 1845

Roebling, John Augustus, 1806-1869

Autograph letter signed

Title: to John Linton

Requests Linton send him about 1000 bushels of cement as soon as possible for the grouting of the old piers which were part of the project to build the first suspension bridge, the Allegheny Suspension Bridge at Pittsburgh, Pennsylvania. Also informs that the undertaker of the Marine Hospital needs 1500 or 2000 bushels of cement as well. There is a note on the verso of the address leaf written later citing information about Roebling from John Bach McMaster's History of the People of the United States.
