The Indiana No. 2 coal did not yield particularly good results during 
) test. The gas produced from it was difficult to clean and con- 
ned a high percentage of sulphur. During the first part of the test 
t gas was low in heat value, but improved in quality after the fuel 
J had been increased in depth. This shows that good results ma} 7 
iobtained from this coal if it is properly fired in the producer, and 
Adequate facilities are provided for scrubbing and purifying the gas. 
t Based on an assumed efficiency of 85 per cent for generator and belt.
