An improved kind of soap for metal
work has lately been described, of some
special advantages, it is said, as com.
pared with those usually employed in
this line-that is, mixtures of vaseline,
oleic acid and fat combined with a
small quantity of rouge and which,
when freshly prepared, leave nothing
to be desired, excepting, unfortunately
that such compositions soon turn rancid
and become unfit for use.
Wheat was recently bought in San
Francisco for shipment to Australia.
Three colonies of the latter country pro.
duce more wheat than they can consume.
while the other four produce less.
Naturally the former would supply the
latter's deficiency, but the foreign do.

in silvering iron recent process in
troduced in Austrian workshops consists
in plunging the iron article into hot di-
lutte hydrochloric acid, whence it is re-
moved to solution of mercury nitrate
and connected with the zine pole of a
Bunsen element, gas carbon or platinum
serving as the other pole. 1t is rapidly
covered with a layer of quicksilver
when it is removed, washed and trans
ferred to silver bath and silvered.
The number of hogs marketed in
the United States has increased from
l4,474, 900, in 1882, to 23,966, 900, in
lS9o-91; and the amount shipped abroad
has shown corresponding increase.
The shipments in 1886 included 367, O00.-
900 pounds of bacon, and $1,000, 900
pounds of ham; and in 1890 the ship.
ments of bacon were $50, 900, 900 pounds,
and of ham s4,oOo,ooo pounds. Mime

Steam pipes have recently been
made of ramie fiber, hardened under
tremendous hydraulic pressure, and
possessing a tensile strength equal to
two and one half times that of steel.
The ramie fiber, or China grass, has
the property of being unaffected by
moisture: it will not shrink nor swell,
1t is a non-conductor of heat 1t can
not rust, and these features, together
with its great strength, are all desir-
able in steam pipes, its utilization in
this line being regarded, therefore, as
one of the possibilities of the future.
Recently published statistics show
the enormous wealth and power of the
foreign steamship companies which do
business out of the port of New York
and maintain Offices in that city. There
are about fifty foreign lines in all, with
an aggregate tonnage of 2, S55, ,2i9. They
include thirty British lines, with 1,073,-
051 tons; five German lines, with 345,.
500 tons; five French companies, with

John W. Bookwaltcr, who owns
$4,000 acres of land in Nebraska, pro-
poses to initiate great reform in farm
life, at an expense of $4,000 or $780,
900, to be met out of his own purse.
His idea is to bring the farmers homes
together into a tastefully arranged
village near each ones land, instead
of having them on the individual
farms He has already started the
experiment on small scale, and says:
II am going to build town hall
and establish free circulating
library. This scheme is in vogue among
the farmers of France, Spain, Italy, and
Switzerland, and is great success. -"
