i increase the per capita to indi-
viduals to an amount that will
make business in this state more
4 desirable and more easy to carry
on. Besides the volume of bus
mess will be increased through
the increase in population which
this great industry will more
than double in the next decade.
The method of handling this
coal is what we term manufac-
tured coal; this is required be-
cause of the peculiar nature of
the Ignite in that when it is ex-
posed to the elements, or being
consumed in the fire box, it
crumbles to. fine slack and in the
first instance it becomes totally
valueless, and in the second, it
shuts off the air passages afford
ing, only imperfect combustion
and allowing from fifteen to
twenty per cent of it's heating
value to escape unconsumed up
the smoke stack, because of the
lack of sufficient air to make the
light hydrocarbons that are
characteristic of Ignite COM
bustible. The idea is to grind
this coal up to powder, take out
the excessive moisture which
ranges from % to 40 per cent
and then mix with a binder and
press into bricks of a convenient
size and shapes to suit the re-
quirements of the different
stoves. There are two ways of
briquetting Goals, both have been
experimental upon in the last
ten years by various individuals
and the United States govern
ment has by congressional ap-
preparation expended something
over six hundred thousand dol
lars. in the last few years in try
ing to briquette Goals. The gov
eminent realizes and individuals
| who are acquainted with the sit
uation agree that within a very
few years the vast fields of an
thracite in Pennsylvania that
once were, will be depleted and
we must look to other sources
for a substitute for this fuel
which has been the standard of
value for all Goals heretofore.
"The United States govern
ment must look for the future
supply Of coal for the great war
ships and because of the confine-
ment of the coal within the holds
of battleships, even bituminous
coal will not answer the purpose
of the danger of spontaneous
combustion, and the only substi.
tute that is yet in sight is in the
form of briquetted Goals. :; The
two systems Of briquetting that
spoke of consists of briquetting
d the coal by fusion with heat un-
der heavy pressure or by the in.
