โฆ Synopsis
Record Production of Portland Cement in xgx3.DAccording to returns received by the United States Geological Survey up to January I2, 1914, it is estimated by Ernest F. Burchard that the quantity of Portland cement manufactured in the United States in 1913 was approximately 92,4o6,oo0 barrels, compared with 82,438, -o96 barrels in I912, an increase of about 9,967,9o0 barrels, or 12 per cent. The estimated shipments of Portland cement during 19I 3 were 88,853,o0o barrels, compared with 85,o12,556 barrels in 1912 , an increase of about 3,84o,4o0 barrels, or 4.5 per cent. On account of a large surplus of production over shipments stocks of cement at the mills apparently increased more than 45 per cent., or from 7,811,329 barrels in 1912 to 11,375,oo0 barrels at the close of 1913. In 1913 the relations between production and shipments were the reverse of those for I912, when shipments exceeded production. It may be necessary to revise considerably the estimates of stocks, but it is believed that these figures for production and shipments are very close to those that will be shown by complete returns from all producers.
Although few definite statements as to selling prices are at hand, it is evident that the average value per barrel was appreciably higher than in 1913 . Increases of IO to 25 cents a barrel are reported from several plants in the Central and Eastern S~ates, but there were slight decreases reported from a few plants in the Rocky Mountain district.
Two new plants, both in Washington. were added to the list of producers during 1913 .
