INDUSTRIAL.

THE starch factory at Cariboa, Me-, is
working up potatoes at the rate of 100
bushels per hour, or 1000 bushels a day.
The factory at Bridgewater is working at
about the same rate.
PROVIDENCE has 100 manufactures OF
jewelry, in which in good times about
$500 hands Of both sexes are employed.
Probably not more than an eighth part of
that number are now at work.
CALIFORNIA; is becoming an extensive
grower of broom-corn. There were 8, 400
third of II made good crop, owing to
the ravages of an insect and the bees.
THE crop of sorghum in the South,
Southwest and West this season is greater
than ever before known. The season
seems to have particularly favored it, and
the quality of the strip Is said to be un-
usually fine. There Is q good demand
for it as fast a. it is manufactured, and the
prices obtained are remunerative and sat
isfsctory. In this section the raising of
sorghum and the. making of moiasses
from i has much fallen off, indeed we do
mot know Of q single instance in this
neighborhood where the business is pros
ecuted. In Bucks and Chester Counties
there is still . fair quantity manufactured,
but il is not ON the Germd,ltotcn
(Po) Telegraph.
The expansion of liquids is proposed
as motor. With gases the expansion is
equal to several hundred times the liquid,
but the elasticity of the gas is also great !;
while with the liquid itself the expansion
u small, but the developed force. enor-
NOUS. In London oil is expanded by
heat, and q slowly-mov1ng pressure Of
without danger of explosion. Printing
presses and rivet and punching machines
have already been successfully run by
this process. Rapid steam pressure by
gearing can be converted into slow high
pressure and invention ought to transpOse
the operation and transform a slow high
pressure into rapid motion and less force.

liz the straw-hurning engines now in
use the straw is fed to the fire in loose
stream, and consumed as fast as it enters
the fire-box. The consumption is there
fore rapid and continuous. A device for
for the utilization of a vast supply of fuel
in the form of dead leaves, grass, etc., has
been brought out, and good results are
claimed for 1t. The grass or straw In the
stove is compressed into solid mass by a
movable follower or weight that rests
upon it. By thus applying pressure to
the straw only the sides of the mass can
burn, the top and bottom being protected
by the follower and CRATE. By regulating
the draft the fire may then be placed un-
der ol.-,Scri6ner for November.
TIE extract of sumach-obtained by
boiling and evaporating in vacuum-has
now been brought into commerce as an
established industrial product 1t is in
the form of a thick sirup, which is with
out any trace of acidity, and capable of
being kept indefinitely, while, as is we'll
known, the common decoction of sumach
soon turns sour and becomes useless. The
advantage in the use of this extract, and
certainly d very important one, lies in the
economy of time and room, since it SIM
ply requires dilution with hot water
The weight of extract, for any shade, can
also be accurately determined, and it can
be conveniently employed in many cases
to produce q desired shade by subse-
quent additions to the bath, and may
often be found of value in dyeing, though
possibly too expensive for general use.
The variety of sumach known as the CO.
riaria is regarded as of superior value for
this purpose; it is the same species with
which, it issaid, all the celebrated leather
made in Turkey is prepared, the bark
being employed for this purpose. 1t is
this sort also which is used in tanning the
choice Bermondsey productions, the pow
der of the leaves and young branches be-
ing thus employed.-N. Y. Sun.
