,;on none is of any utility but what Is
brought within the space to ue nea,ea ;
and the longer i. can DC retained tae's
me more useful it will be. This Is a
Sery obvious principle, and very I'M
sr,,nt .one. But obvious and impor'
sant as it is, our best constructed hfe
places manifest gorgeous violations o.
E The Russian Stove preserves nearly
ali the heat that is produced. before
the current of heat can pass through 20
MANY flues it is nearly all absorbed oy
The brick and the more ehectually 10
proven, it's escape valve is placed near
the mouth of the last hue, which IS cio'
sed as secn Us the smoke OF the hre mas
escaped, and thus all the communiea'
ton with the chimney is cut of. AS
brick and lime are poor conductors OF
ealorie, this stove when once heated,
must retain its heat a long time anu
impar,ing it but slewiy>t the atmos'
pbere of the room, it will keep it long
time warm.
4th In all ths common stoves, ana
in our fireplaces, portion Of the air III
the room is consumed in combustlon'
and q, current of heated air is constantly
ascending through the chimney. To
supply the deficiency thus occasioned,
the cold air rushes through every ere.
vice about the windows and doors, This
evil is provided against in the Russian
Stove. The cold air brought from with
on. by means of a pipe, is effectually
heated in circulating through such a
mass of hot brick, and thus not only
elevstes and equaIizcs the temperature
of the room, but keeps it constantly fill
ed with pure and wholesome air.
To answer all purposes of utility The
expense of erecting this stove is trialng
1t will take up about 700 brick, and a.
bout three days work II a mason.-For
permanency, FIRE brick or stone, is to
be recommended about the fire place
fit be desired to ornament the stove
with plaster, or marble, the expense
would of course be enhanced.
From what has been said you will
perceive the superiority Of the Russian
stove over any other methcd vt aslng
fuel in common use among amongst US.
| SUPPOSE you will also perceive its SUI
periority over the method OF heating by
steam. Steam, in its condensation. can
only give out the heat which became
latent during its conversion from water
to that state This heat was ~ obtained
fom the combustion Of the fuel To re-
tain for use all the heat thus evolved is
the Most that can be desired The Rus
sian Stove retains nearly all. In heat
i.g by steam, the fire is generally with
ont the room TO be heated, and much Of
the heat is diss;pated and lost from the
boiler and its furnace.
l have or!y 10 add to this long letter,
thi, tie practical use OF the Russian
Stove is found to justify all that might
be expected from the psincipies Of its
construction. have had one e-ectet
in our college which has realized our
sanguine expectations.
With respec:. your oba't servant,

raj other of these stoves have been e.
rscted under my superintendent, which
answer every desired purpose.
