The Texas No. 1 is a brown lignite strongly resembling that pre- 
Dusly tested from North Dakota. The gas from it was not so rich 
that from the North Dakota lignite, but it was higher in heat units 
an is the gas obtained from ordinary soft coal. The lignite was 
)re difficult to handle in the producer than bituminous coal, but 
frequent poking and by supplying the right amount of air to the 
oducer the bed was kept in good condition, and at the end of the 
irty-hour test it was possible to break up the clinkers in the bed, 
quiring the removal of only a few ashes before beginning a new 
it. This lignite yielded a large amount of tar of the same kind as 
3 lignite previously tested. As a producer fuel it is better than 
iny grades of bituminous coal.
