1210 MU~ERALS YEARBOOK, 1941
     FUELS AND POWER

 Fuels —According to monthly reports of producers, supplemented by
a few estimates by the Bureau of Mines, the following quantities of fuel
were consumed at portland-cement plants in the TJmted States and Puerto Rico
in 1941 in making 163,629,000 barrels of clinker (unground cement) and 164,030,559
barrels of fimshed cement Coal, 6,831,825 short tons; oil, 3,552,030 barrels
(42 gallons); and natural gas, 54,207,900,833 cubic feet Corresponding figures
for 1940 are Clinker produced, 130,141,000 barrels, and finished cement produced,
130,216,511 barrels. Fuels consumed were: Coal, 5,633,156 short tons, oil,
2,424,976 barrels, and natural gas, 41,948,699,007 cubic feet
 The first and second of the accompanying tables on fuels compare the output
of clinker and finished cement in 1940 and 1941 with the estimated fuel consumption
by processes. Similar data were published in Statistical Appendix to Minerals
Yearbook, 1935 (p. 200), covering 1933 and 1934. The third table on fuels
shows detailed data
* on quantities used in 1940 and 1941.
