to be mined at some future time. Any well drilled in such township,
whether or not it passes through any coal, the same being barren in

=Composition of illuminating oil for use in mines.=

Sec. 974. No person, firm or corporation shall compound, sell or
offer for sale for illuminating purposes in any mine any oil other
than oil composed of not less than eighty-two per cent, of pure
animal or vegetable oil, or both, and not more than eighteen per

shall not be less than twenty-one and one-half, and not more than
twenty-two and one-half degrees Baume scale, measured by Tagliabue
or other standard hydrometer, at a temperature of sixty degrees
Fahrenheit; the gravity of such mineral oil shall not be less than
thirty-four and not more than thirty-six degrees Baume scale,
measured by Tagliabue or other standard hydrometer at a temperature
of sixty degrees Fahrenheit, and the gravity of the mixture shall
not exceed twenty-five degrees Baume scale measured by Tagliabue or
other standard hydrometer at a temperature of sixty degrees
Fahrenheit. Each person, firm or corporation compounding oil for
