The Colorado No. 1 is a black lignite which clinkered badly in the 
)roducer, in spite of frequent poking, but the clinkers were not large 
,nd could be broken from the top of the producer. The gas was of 
i good, uniform quality, and there is no doubt that the fuel can be 
sed to advantage in producers. It yielded a large amount of yellow 
lignite tar."
