Weathering of- the Pittsburg Coal Bed at the Experi-

35,” 35 pp.; 14 fig. . (During the driving of two entries
an unusual opportunity was presented to study the
variation in the character of the coal at increasing
depths. Results show that weathering has affected
the coal for a distance not greater than 50 ft. from the
outcrop, the amount of cover at this distance being
less than 25 ft. The weathering effects are manifested
in a lower content of carbon and hydrogen, and higher
content of oxygen, in the coal substance, a correspond-
ingly lower calorific value, a larger proportion of com-
bined water, and a much diminished power of
consuming oxygen from the air and liberating
methane.)
