PRODUCER-GAS TESTS. 117 
The Wyoming No. 2 is a bituminous coal. It burned without any 
tinkering, leaving a large amount of white ash similar to that obtained 
rom wood. The gas was not uniform in quality, on account of the diffi- 
ulty experienced in keeping the bed in good condition. An unusually 
irge amount of yellow tar was taken from the gas. 
SUMMARY OF RESULTS. 
The table given herewith shows in a condensed form the results 
btained in the producer-gas tests.
