1914 GYPSUM PRODUCTION.
There Was Decrease in Tonnage But In
crease In Value.

According to G. +. Loughlin, Of Thu
U. >. Geological Survey, the production
OF gypsum in the United States in 1914
was marked by a decrease in tonnage
but an increase in value, an increase due
TO a strong advance in the price OF cal.
cined gypsum, which more than offset a
decline in price OF crude gypsum.
| The quantity of crude gypsum mined
in the United States in 1914 was 2,476,-
465 short tons, compared with 2,590,50S
tons reported mined in 1913, decrease
OF l23,043 tons. The gypsum sold with
out calcining and used principally as
land plaster and as an ingredient in Port
land cement and paint amounted TO 443,.
6S7 short tons, valued at $646,799, n
decrease of l9,440 tons in quantity and
S50,267 in value in comparison with 1913,
when the sales for similar purposes
amounted TO 463, 1886 short tons, valued
at $697 ,066. The material marketed as
calcined plaster was l,656,066 short tons,
valued at S6249 100 as compared with
l,773,840 tons, valued at $6,077,756, sold
calcined in 1918. The total value of all
gypsum marketed in 1914 was $685. 1889,
as compared with S6,774, 1922 in 1918, an
increase of $l2l,l67.
Considerable quantities of gypsum
plaster, or staff" were used in the Pan
anna Pacific exposition buildings at San
Francisco end in the Panama California
exposition buildings at San Diego, but
they were not sufficient to offset the
general decline in tonnage elsewhere. A
marked increase in the sales of calcined
plaster was noted in 1902 and 1903, which
also was largely due to the consump-
ton of "staff" for buildings at the
louisiana purchase exposition buildings
at ST. Louis.
Gypsum was produced in Is states
and in Alaska in l9l4, the same states
output in this year as in 1918.
The relative rank of the three leading
states has remained unchanged for the
last four years, New York ranking first,
Iowa second and Michigan third in the
output of crude gypsum.
The quantity of raw gypsum ground
and sold for land plaster amounted in
1914 to 52,945 short tons, valued at S97,-
7l6, as compared with 54,sl5 tons, val
led at S95.953, reported in 1913. The
quantity of raw gypsum sold for the
manufacture of paint and of Portland
cement and for various other purposes
amounted to 390,742 short tons, valued
1t S549 ,0S3. as against 40s, 32l short
.ons, valued at lib, sold for similar
in 1913.
The total quantity of calcined gyp-
um sold in 1914 was Il7,7s3 tons less
han that sold in 1913, but the total
'alue was sl7l ,434 greater. Nearly e5
Ter cent of the domestic calcined gyp-
UNI marketed in the United States, or
,565,37 tons, is for use as wall
laster, Keene's cement, plaster Of paris
nd other uses. About l,250,000 tons of II
his quantity represents mixed wall plas.
