PRODUCTION OF PORTLAND CEMENT IN 1913
According to returns received by the United
States Geological suivey up to Jan. 12, 1914, it is
estimated by Ernest F. Burchard, that the quantity
of Portland cement manufactured in the United
States in 1913 was approximately 92,406,000
barrels, compared with 82,438,096 barrels in 1912,
an increase of about 9,967,900 barrels, or 12 per
cent. The estimated shipments of Portland cement
during 1913 were 88,853,000 barrels, compared
with 8-3,012,550 barrels in 1912, an increase of
about 3.840,00 barrels, or 4.5 per cent. On account
of a large surplus of production over shipment:;
stocks of cement at the mills apparently increased
more than 45 per cent., or lrom 7,811.329
barrels in 1912 to ll.375.Ouo barrels at tbe close
of 1913.
Although few defnite statements as to selling
prices are at hand it is evident that the average
*,alue per barrel was appreciably higher than in
1912. Increases of 10 to 25 cents a barrel are reported
from several plants in the central and
eastern states, tut 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.
The Elkins Coal & Coke Co. has seemed a contract
for 10,000 tons of coal per month during
1914 from the O'Neil Sons Co. of New York, and
shipments were started during January.
The Davis Coal & Coke Co. is enlarging its
offices at Cumberland, Md., under the direction
of Vice President A. XV. Calloway to accommodate
the entire headquarters force of the company,
which is being moved from Baltimore, Md.
