Stat1st1cs. Cement manufacture is quite a modern industry. Some idea of its progress may be gathered from the following approximate figures relating to the production of Portland cement: --1890 1907 Great Britain.. 1,000,000 tons 2,750,000 tons Germany.... 1,500,000, 5,000,000, United States.. 50,000, 8,000,000 Three years later the total production had reached something like 25,000,000 tons.
