SCIENCE, INDUSTRY, AND INVENTION

"A scheme has been preached in England which
is bold and striking enough to have originated with
Yankee The project no less than that of replacing
the nine thousand tuns of coal consumed daily in
London by gas which is to be made at the coal fields.
and conveyed in an enormous main, three hundred
miles, to the great metropolis TIE practicability and
advantages OF using gas for cooking and other domestic
purposes are now fully established. powerful and
most economical gas may be formed by saturatjng
steam with carbon. The gas should be manufactured
the colleries in large furnace similar to iron
furnaces, but not so lofty, and by alternating opera.
tionthat is to say by excessively blowing in air to
raise the coal and furnace to high heat during which
time the products Of combustion must be allowed TO e.
cape, and then throwing in steam to form gas Tho
steam heated by the gases passing off, TO be intro
duced at the upper part Of the furnace and confined
to force its way downward through dense mass Of
hghly-heased coal, by which means it will become
fully charged with carbon. Between these two
alterations portion of fresh coal is to be introduced
into the furnace The gas thus obtained will consist Of

of gas-hoders must be provided the works. from
whence pipes must b laid to London, where another
set of gasholders must also be provided. Into the

may be laid to the stovegrates at present in use,
