ACCORDING to DR.. Wicdehold, fungus
growths in cellars may bo combatod
either by burning sulphur or by pour.
ing two parts OF concentrated sulphuric
aold over one part Of common salt, und
SO closing all openings as to prevent any
escape Of the vapors.
WATER made slightly salt, and to
which bran TO tho proportion Of one
quart to every gallon has been added, is
said to increase tho yield Of milk by 25
por cont. II it il given TO COWS % thoir
ordinary drink. After short time The
COWS will refuse pure water, unless they
are very thirsty.
WHEN potatoes arc frozen tho amount
OF sugar they contain is doubled, The
starch undergoing q corresponding dim
mutton while part Of TIE protein passes
from the coa9ulable into the soluble
form. During tho process of roiting.
the potato loses hall its heterogeneous con-
stitucnts and the whole Of the sugar
IT is found that sawdust cun be con-
vertod into liquid wood" and after
ward into q solid, flexible, md almost
lndestrnctible mass, which, when
Incorporated with animal matter, rolled
and dried, can be used fer tho most deli

accomplish tho method pursued is to
immcrsc tho dust of any kind Of wood in
diluted sulphuric acid, sufficiently
strong to affect tho tibers, for some
days, the finer parts being then passed
through n sieve, we'll stirred, and al-
lowed to settle. The liquid is t,,wiuod
from tho sediment and the latter mixed
with prorortionntc quantity of animal
matter, similar to that used for glue :;
the mass is tlien rolled, packed iu
mol,ls, md allowed TO dry.
An automatic hri ,k.mal<ing machine
of great efficiency md power is among
the recent English inventions. The
driving pullcys move ut high speed :;
and the first SHAFT, which is carried on
an outside bracket, gears ly mcans of IL
pinion into two eqnal g-whccls.-these
driving, respectively, one the upright
plugging Shaft ond top 1aoId, nnd tho
other the final finishing press. The lat
ter is formed by MI overhead cross head
carrying stamp, Mid connected with
tho shaft below by two cranlis and con-
necting rods-this cross head and stamp
descending into tho dio in tho table be-
low, into which tho brick has boon de-
livered, and finally oompressing and
hardening it. Underneath the table
and die is another revolving crank or
cam, which, as it rises, pushes tho fin
ishcd brick from the mold, ready for
delivery.
TIE beautiful and far-famed rose and
rod shades of French sh,ss uro produced
in the following mrnncr. A certain
amonnt Of anrifcrous glass is prepared
beforehand and run in thin plates, and
fragments Of these plates arc used by
tho glnss'blower to fuso upon his work,
thus giving it superficial coloration.
1t often happens that one and tho same
composition OF aurifcrous crystal gives
plates Of very different shades--some
colorlcss, others tingcd more or less
dcoply with roso and rcd, and some al
most black these differences being due
to two causes, namely, the temperature
Of the mold into which tho melted mctal
is run, and the temperature of the fur
mace in which the fusion has been effect
ell. For light-colorcd plates, the tom
pernturo is made low and tho mold very
cold. Blue plates are sometimes pro.
duccd undor tho same circumstances
which, If relocated, tako tho normal
color.
