Note. — The calories of Nos. 6 to 14 are computed from the analysis by the author. 
The above coals vary greatly in composition and in heating power, 
and it seems likely that this field, as elsewhere, each seam will be 
found to have a characteristic composition. The source of Nos. 10-14 
is not known, but possibly some of them are from the opening on 
Carbon Creek from which No. 1 was obtained. The difference be- 
tween the amount of moisture in these samples and that in sample 
Nos. 1-5 is probably due to the fact that the latter were placed in 
sealed cans as soon as taken and no opportunity was given for the 
coal to dry out. The very high percentage of sulphur in Nos. 13 and 
14 is probably due to their having been taken, not from the entire 
thickness of the seam, but from pieces of coal which were picked for 
their hardness and apparent cleanness. The one who took the sam- 
ples evidently overlooked the fact that their exceptional hardness 
was not due to the coal being nearer anthracite, but to its containing 
a large amount of pyrite (sulphide of iron).
