WESTERN FIELD. 
The coal in the west end of the bituminous belt as seen on Eska and Tsadaka Creeks has 
been considered locally as lignite. The analyses, however, indicate that it is in all probabil- 
ity a low-grade bituminous coal. This conclusion is supported by the fact that the coal does 
not differ greatly in physical properties from that on Chickaloon and Kings creeks. The 
seams have about the same characteristics as those o the east. Much of the coal is bright 
and hard, but there are frequently dull bands with a shaly fracture which resemble a very 
coaly bone. The appearance of these may be due in part to impurities, but is possibly also 
caused in part by less complete carbonization. There is little doubt that the coal is of Ter- 
tiary age, and the beds are presumably the stratigraphic equivalents of those to the east .
