surface, takes clean, sharp, well defined
impression from-the matrix, which Is not
excelled by any other process known.
/ A brief description OF the method OF the
manufacture of-Ofnamental bricks and
tiles may not be amiss.
| When the clay-bank is IN the right con-
dition to repress, Is before described, 1t is
busted on the face side which is to receive
the impression, and this side is placed
upon the matrix, which is thin plate
with the reverse 81. the pattern you desire
upon one side. This matrix or mold is i'm
the bottom Of The press box in some
presses. Manufacturers have various APP
plances Tor making ornamental work
With some the plate is placed in the bot
tom OF the press and Others have the
plate on top Of the brick while pressing.
In the first case the brick is lifted off
from the plate after pressing, and in the
other tho plate is removed before the
pressed brick is lifted entirely from the
mold.
A third method is to have the mat,ix
fastened to the cap, top plate or follower
as the case may be-according TO the kind
OF press you are using-and when the cap
ia lifted of the matri2 is lifted with it and
then tho brick is lifted from the press with
methods have in attempting 10 remove the
plato from the brick. Each of these
methods have their respective advantages,
and the manufacturer must use such
method as seems to him best.
To manufacture. TO the best advantage
three presses should be used--onc for large
tiles, ono for brick aud one for edge work;
but one press will answer by changing the

Various substances are used TO prevent
the matrix adhering to the clay. Oil is
most generally used, but in designs having
great relief and dcprcssions IL is some
times almost impossible to remove the
matriX from the ware without injury;
others use dust OF some kind. Very fine
sand, which will burn good color, pull
verized coal, charcoal, etc, arc also used.
The writer has found that brick dust,
passed through boiling cloth, is the very
best thing lac ever used; burns, Of course,
the same color ~ the clay and produces a
rich, velvety surface, and the bricks never
stick
When the ornament required is very
bold, 1t is best to reprcss twice. After
tho first pressing, which should not be
very hard, tho tile is busted. When IL
has shrunk Just enough to drop easily into
the press, the supcruous dust is blown
of, either by bellows or lung
power, and then pressed the second
time firmly. The subsequent treat
ment consists in carefully removing
any superiluous clay from the edges
q little hand rubbing, careful drying aud
burning.
The main thing, 10 insure success in
ornamental work, either holdings or
pressed work, is thorough preparation Of
the clay.
II should have sand or grits enough in
II 10 prevent undue shrinkagc or liability
TO crack in drying and burning. For the
best ware. clay that has been once burned
and pulycrized should be used 10 the extent
OF about % per cent. TO mix with the green
clay, and ii should also lie week in the
pit after being wet, rs long after being
plugged the iirst tune rs possible before be-
ing run into molding or Tor pressed ware.
Success in brickmaking MS in all other
manufacturing enterprises, is determined
largely by attention 10 details.
When urged 10 be moro particular in
this or that matter, the man who replies
"Oh. that won't make much difference
or, II can't Afford To take 20 much
trouble; can make brick good enough
without 80 much 'iuonkeying,' will wake
up some fine morning and find some com
pctiior, who was careful and particular in
the details or 30 called small matters, has
secured the best contracts and the most
paying trade.
In conclusion, NO say again, "tcmper
your clay we'll, manufacture carefully,
burn thoroughly, and IL you do not realize
the Dutchman's per cent, you will have
tho satisfaction OF doing your work hon.
csily, aud success will surely crown your
efforts"
Prof. II. G. Carpenter, OF Lansing,
Mich, said that he had made tests which
established the superiority Of the soft
mud brick
Mr.. williams, In reply, said that the
United States Government had made tests
aud In awarding contract had declared
in favor OF the still mud process.
Al this juncturc tho proceedings were
interrupted by Mr.. Eudaly, who, in q
