CHARACTER OF THE COAL. 
The physical properties of the coal are very much alike in all th< 
seams and in all parts of the field visited b/y the writer. The coa 
resembles the harder bituminous coals of the East more than it doei 
anthracite. It is doubtful, too, if much of the coal could be sized s< 
as to compete with anthracite coal for domestic use. Furthermore 
under ordinary handling it will probably crush to almost the sami 
extent as the harder grades of semibituminous coal; this will no 
seriously impair its value for steam purposes, but will necessitati 
very careful handling if it is to compete with Pennsylvania or Welsl 
anthracite as a domestic fuel. 
The following table includes all the available analyses and calori 
metric tests which have been made upon the Bering River coal. Th< 
first nine samples were collected by the author and represent the com 
position of the entire seam; that is, coal was cut evenly from the sean 
from roof to floor.
