SMOKELESS COMBUSTION.
A FURNACE IN WHICH THE BITUMINOUS
GOALS ARE so PERFECTLY con-
sUMED THAT THERE Is NO

The strike among the anthracite coal miners
seems likely to bring to definite conclusion
the bitter of conflicting interests which has
been waged between the public at large and the
municipal authorities on the one hand and the man.

When the law passed forbdding the of
soft coal within the city limits 1t was recognized
a proper and legitimate exercise OF power for
the public veal Naturally. too it surmsed
that the upsho Of the trouble would be the general
adoption by the steam boiler of appliances
which would in some mysterious manner do away
with the smoke nuisance. which had been the un-
failing result OF soft coal combustion.
The event has proved that far the majority of
the steam producers have pursued temporizing
policy, burning the smokeless anthracite coal By
day. while at night-but who knows what goes on
in New-York by night? 1t is said by those who are
out after dark that then the great chimney stacks
beich forth great quantities of blackest smoke ana
Smoke is composed of minute unconsumed par,
