COAL BRIOUETTES.

y method of COMPRISING broken and
pulverized coal, so that it is more
valuable than coal as it is now used in its
regular sizes. y company whose stock
pays large dividends. Many attempts
have been made in this country and else
where to utilize successfully the dust
and small broken coal from the mines,
and thus make them commercially valu-
able, instead of being waste products;
but thus far in this country, except in a
small way, all attempts have proved
futile. Generally an effort has been
made to mix pitch or tar with the waste
product, but the final result of these adj
mixtures can easily be conceived when
used in stoves and furnaces. In Austria,
however, a method has been developed of
using these products, which makes the
compressed coal dust even superior to the
coal it comes from, and bids fair to revo-
lutioniZe matters so that eventually it
will be an object to reduce all coal to
broken particles and form it into brick
before using it. No pitch nor tar is used
in forming the bricks made by this
method, and their practical use in Europe
for some time past has demonstrated
them to have an evaporating capacity of
from ten to fifteen per centum over the
coal from which the bricks are made.
Among the advantages of the bricks or
briquettes made by this process are:
They are superior to Cumberland coal
for blacksmith use, making finer weld,
on account of the prevention of oxidation.
They are porous and admit oxygen, caus-
ing better combustion of the carbons
by taking up a portion of the free
sulphur, which would otherwise be
thrown off, and cause a loss in their
evaporatng capacity.
| They prevent the oxidation of the CRATE
bars and perforation of boilers, consum
ing the sulphurous acid given off from
ordinary coal, and which has these des-
tructive tendencies. In reverbatory fur
naces for calcining soda or its com
pounds, they are superior to coal, con-
Stunning all the free sulphur and prevent
ing absorption. For domestic use they
are equal, and in many points superior,
! to coal.
For sanitary purposes, also, they are
not only much SUPERIOR but so much
so as to make their general use in the
future an absolute necessity; in fact,
when used in open CRATES, stoves, in
parlors, bedrooms. etc, at even double
/ the price of common coal, the absence
of coal gas and other deleteriOuS effects,
and giving IL pure. healthful atmosphere,
is such as to make a demand for them
even at the double price.
The effects of carbon gas are COM
pletely coUnteracted by the use of the
coal briquettcs, and lung and throat
troubles thereby avoided, or greatly
multgated.
Leaving out the superiority of the
| briquettes for railroad. steamship. and
manufacturing purposes, if they should
be manufactured solely for household
use, it would not be long before resort
would have to be had to pulverizing
coal that is now graded in sizes, to man
ufacture enough briquettes to meet the
demand, and making the price of them
much greater than for coal, which diff
ference would be cheerfully paid on
account of the advantages above enum-
Grated.
The Northwestern Land and Coal COM
pany has secured all the right, title, and
interest in the above patents in the
northwest. The $4,000 acres of land
owned by this company of very valuable
Ignite coal deposits in the State of
North Dakota will not only produce
large revenue to the stockholders from
the manufacture of coal briquettes, but
will give employment to large num-
Der of people in mining and manufact-
uring, and will render these lands very
valuable for agricultural purposes.
This company pays regular 10 per cent
dividends in February and August from
the net earnings, and the addition of
this valuable requirement will put this
company in a position second to none
as dividend-paying investment. Speci-
mems of the briquettes made from the
coal of this company are on exhibition
