brick. In this way the water smoke ia
driven of, not by the smoke Of the kiln
fire, but by pure atmospheric air OF proper
temperature.
Finally, may mention two other sys-
TENS of continuous kilns-the Dueberg
kiln and the Mendheim kiln; tho former
Is modification OF tho Hoffman kiln. Tho
green brick arc placed on platform cars
and those are run into the burning cham
ber, as in the Railway kiln already men
toned. The burning chamber OF the
Dueberg kiln, however, forms a continu-
Gus circuit OF rectangular shape in plan,
similar to tho shape Of many Hoffman,
kins. The cars are mt rest in the burning
chamber during the process OF burning
being drawn out OF the kiln one by ono
after the burning is finished and the brick
have become sufficiently cool. The fire Is
travelling around in the Dueberg kiln OK
actly in the same manner as In tho IIof.
mann kiln; coal rs well us gas may DO
used for firing. Ny principle object in
constructing this kiln was 10 obviate the
labor OF setting and taking out the brick,
TO be dono inside OF the hot arched burn
ing chamber, as in the Hoffman, kiln as
well IA in other arched kilns which must
be artificially lighted, even in day time.
The Mendhoim kiln consists OF com.
binati0n OF "A series OF arched burning
chambers, connected with each other by
flues, 30 as 10 form a complete circuit.
These kilns are fired by gas and the fire
proceeds from one chamber TO another,
passing through said 0ucs, thus travelling
around similarly as in the Hoffman, kiln.
The progress OF the fire, however, is much
slower in the Mendheim kiln. on account
OF lis being compelled to pass through
said ilnes, the area OF which is much
smaller than that Of the burning cham
beers. For this and other reasons the
Mendheim kiln does not afford the same
economy in fuel rs tho Holman kiln.
In conclusion, would say that any
considerable saving in fuel as compared
with old-fashioned kilns, can DO obtained
only with continuous kilns, the burning
chamber OF which must form an endless
circuit OF nearly equal area all through its
length, withous partition walls, II the ca
pacity lturn-out) Of the kiln shall DO such
as TO pay for the cost OF erection.

in the course of his remarks, stated that
the cost of continuous kiln IN $4,000,
and that by that process brick could be
burnt for - cents per 1000 Ito thought

Mr. Mckain thought that tLeru wis no

Mr.. Il. W. blair made the point that the

Mr. Baytley desired tho convention TO
bear in mind that continuous kiln did
not necessarily cost SIS, ODO. but that a 81.

a cost OF seven g. eight thousand dollars
