"The principal characteristics which, in the process of manufacture, sharply and clearly distinguish Portland cement from Limes, Hydraulic Limes, and other Hydraulic cements, are the necessity for carefully proportioning and finely grinding the raw materials to insure a homogenous [sic] mixture, and the extremely high temperature at which it must be burned in order to insure a sound a trustworthy product" – p.
