ing and mixing he produced a Portland cement which he exhibited at 
the Centennial Exhibition in 1876 at Philadelphia. This cement com- 
pared favorably with the imported cements of that date. _ 
Up to 1880 five other works were established as follows: At Rondout, 
N. Y., Kalamazoo, Mich., Wampum, Pa., South Bend, Ind., and Rock- 
land, Me. Of these six works but three have made sufficient success to 
survive. In reality the Portland cement industry in the United States 
as a commercial success dates back no further than 1882; 21 years of 
Portland cement life brings us to the year of its majority, 1903. Below 
is given a table showing the production of Portland cement in this country 
and the importation of foreign cements from 1880 to 1902 inclusive.
