These coals are intermediate in fuel ratio between the Bernice basin 
or Loyalsock (Pennsylvania) semianthracite and the Pocahontas (West 
Virginia) semibituminous. They are purer and have a higher heating 
power than the Loyalsock coal, although they lack its anthracitic 
physical characteristics and have a lower fuel ratio. They are almost 
identical in heating power,, as well as in the low amount of impurities, 
with the Pocahontas steam coal of West Virginia, but excel this coal 
by having a higher proportion of fixed carbon. These coals can not 
be compared with any other coal with which thev are likely to come 
into general competition for they are far higher in heating power and 
in purity than any coal mined upon the Pacific coast, either in the 
United States, in British Columbia, or in Australia. 
Samples 2 and 3, from openings 1 mile northwest of Canoe Land- 
ing on Shepherd Creek, and from near the headwaters of Trout Creek, 
are probably representative of the thinner seams of this region.

These coals differ from the coal of the thicker seams discussed above 
in having a less amount of fixed carbon in proportion to the volatile 
matter and in having a higher percentage of ash and sulphur. The 
heating power is consequently less. Nevertheless, they resemble coals 
of the semibituminous type that enter the market as high-grade stean 
coals. They correspond in texture, composition, and heating power to 
the high-grade Pocahontas (West Virginia) and Georges Creek (Mary 
land) steam coals, and also to some of the semibituminous coals o: 
Wales.
