Lndian Territoiy coal No. 1 is a moderately free-burning coal. It 
ted fairly well in the producer and made a good top crust, which 
s easily worked. It was charged into the producer after being 
ished and screened over a half-inch screen. This was done while it 
s wet, and considerable slack was carried over with the lumps. 
This coal may be considered a good producer coal.
