BULLETIN 102, UNITED STATES NATIONAL MUSEUM, 
WASTE OF GAS COALS IN BEEHIVE COKE OVENS. 
At the present time, under average conditions, the beehive coke 
ovens in the United States waste annually about 240 billion cubic 
feet of gas, as shown in Figure 6, that could be used for public-utility 
service. Since the total annual manufactured gas sold is 326 billion 
cubic feet, as shown in Figure 6, this beehive coke oven waste is 
equivalent to nearly three- fourths of the 
gas sold. There is little wonder that the 
foreigner has referred to us as “ butchers ” 
in connection with the misuse of our own 
resources. 
About one-lialf of this beehive coke oven 
waste, or 120 billion cubic feet annually, 
is wasted in the State of Pennsylvania. 
Since the manufactured gas used in the 
State is 27 billion cubic feet annually, this 
waste represents four and one-half times 
the manufactured gas made in the State. 
Much oil is now needlessly used in main- 
taining obsolete candle-power standards. 
GOVERNMENTAL RESEARCH ON CORRECT MANUFAC- 
TURED -GAS USE. 
The United States Bureau of Standards 
has for several years been testing manufac- 
tured-gas appliances, ascertaining defects, 
and securing data for needed improve- 
ments. 8 The Office of Home Economics of 
the United States Department of Agricul- 
ture, in its experimental kitchen, has been 
carrying on extensive tests on actual cooking 
used BY public and gas operations with gas under varying condi- 
wasted in beehive coke tions of use. These tests have all brought 
out the many ways in which improvements 
may be made to bring about correct and safe use of manufactured 
gas. The results of these tests are reflected in the directions for 
correct use in part 2 of this bulletin.
