"A curious and interesting calcula-
ton has been made by Professor Rogers,
of Washington, d. c., on the dynamic
power of coal According to the pro-
fessor a single pound of good steam
coal has within it dynamic power
equivalent to the work of one man for
one day. Three tons of the same coal
represent mans labor for period OF
twenty years, and one square mile of a
seam of coal, having depth of four
feet only, represent as much work as
! 1000, 900 men can perform in twenty
! years.
