Wheresoever msn goes the rat follows or accompanies him. Town or conntry are equally
agreeable tohim. He is a most enterprising
traveler, and is continually passing from one
country to another. Soarce a ship leaves a
port, withont taking on board its complement
of rsts for the voyage. It is thus that this destructive little rodent hss distributed himself
over the entire civilized world. Theseremarks
apply more particularly to the brown or Norway rat.
Although called the Norway rat, this vsriety
of rodents did not originate in that country, but
came from the wsrm regions of Oentrsl Asia.
It seems to have taken up its migratory habits
‘about the time of the revival of commeroe, nesr
the year 1700. It found its way into southeastern Europe in the early psrt of that century,
where, after multiplying largely, it commenced
a northward msrch into Russia, crossing the
Volga in large troops. It resched England in
1730, and France in 1750,
In its march through Europe it drove before
it or exterminated the black rat—the native
house rat of that continent. In 1775 it “‘took
ahip” and crossed the ocean to Americs, whither
it had been preceded
by the black rat a
few years before;
and here also it soon
exterminated its
black congener, and
has reigned since

prefers the upper psrts of dwellings to cellars or
any low, filthy places. He is the aristocrat of
therat tribe; is less gregarious than others, and
travels in small, select parties. Of course he
is not a fighting charscter. On the contrary,
the brown rat is very ferocions, fights and
travels in Isrge companies, and pnrsues
war to the death against his enemies.
Our illustraticn presents a view ofa lively
combat between a party of brown and black
rats—the latter having evidently been surprised
at a convivial entertainment in the corn crib of
some Western farmer. Their mode of battle
and quick dispatch has been vividly portrayed
by our artist.
The black rat never found its way to California—his race, on this contlnent, was cut short
by the break in human habitations in the ‘‘far
West’’ of the Atlsntio Ststes, where his ‘‘forlorn hope,”’ as an advance gnard, was overtaken by the vindiotive pursuit of his ancient
enemy.
The early residents of San Francisco say
that the old Mission and the early dwellings in
the city proper, were occupied by a variety of
white rats; but as no specimens have over
been noticed by our scientists, the inference is
that the ‘‘white rats’’ were nothing more than
a variety of the brown, which, at that time,
had been but sparsely introduced by transient:

ships comingto this Cosst with supplies for
the esrly Jesuit missionary settlements, and
stopping to gsther hides for aretnrn cargo.
This supposition gathers strength from the
fact that the brown rat is prone to exhibit this
varistion of color, whenever it becomes isolated, or for any resson oeases to multiply rapidly
—a condition that was well fulfilled during the
period anterior to the advent of the gold-hunters, when civilized habitations were 80 scarce

the rat family is extremely loth to remsin with
dwellers in huts.

the Mus Californicus,—commonly known as the
short-tailed rat,—a variety of the wood rat,
which, from the disinclination of the brown
rat to follow into outlying bushes or woods,
never has, and probahly never will be exterminated by the new-comer. This rat, consequently, is still found in great abundance,
especially all along the Cosst Renge, both in
mountain snd valley, where it builds mounds
of sticks, leaves, etc., often ten feet in hight
and twenty in diameter st the bsse. These
mounds serve a8 convenient retreats for the

It is gratifying to lesrn that one of the most
importsnt msnufacturing interests of the more
industrial nations of Europe, is also stesdily
and advantsgeously gaining ground in our own
country; we allude tothe manufacture of silken
goods. A cotemporary chronicles the following
facts and figures in relation thereto, bunt omits
to tall us that the raw silk from which these
fabrics are wrought, are obtsined almost entirely from foreign countries where cheap labor
is the rule. !
The silk interest has grown in the last few
years much beyond what has been generslly
supposed. A report issued by the silk manufacturers of America ststes that the growth
of this production is steadily incressing. Within a decade it has sprung from an insignificant
and unpromising experiment, and now bids
fsir to become one of the lucrative branches of
our varied industry.
There is said to be at this time a capital of
over $30,000,000 invested in the business in
this country, against less then $3,000,000 in
1860. Sixteen thousand operatives are omployed, earning $8,000,000 per snnum, and

Nitrate or Sopa.—The following item comes
from South America: In view of the vast national importance of the new law limiting the
produotion of nitrate of soda and msking the
Government the sole exporter of that most valuable article, the following data will be found
interesting, as showing the steady increase of
the demand:
In 1870, 2,500,000 quintals of nitrate were
shipped from Pernvian ports to all markets
abroad. .
In 1871, this figure was incressed to 3,000,000 quintals, and in 1872 reached the very respectable sum of 4,420,000 quintals.

Ratiways 1n Soura AmeRroa.—The railways
from Arequipa to the lsrge interior cities of
Cuzco and Puno are being pushed forward
with much energy, the natural obstructions to
be overcome rendering the labor one of extreme
difficulty. Once on the level plsteau rnnning
from Pano to within sixty miles of Arequipa,
and that point is almost reached, the advance
will be remarkably rapid. The line from
Ohimbote to Husraz, considered by msny well
acquainted with the resources of the country
as the most important railroad in Peru, has
some thirty-six miles now ready for ironing.

Singular Discovery of Gold.
A gentlemen informs the Nevada Transcript
of a most singular disoovery of a piece of gold,
at Red Hill, abont a mile from this oity. He
says one of the owners of the land was walking
by a piece of ground, afew days ago, where
the top dirt had been washed offto the depth
of about five feet, and saw something shining.
He went tothe spot, and ascertaining it was
gold, took out apiece weighing about three
ounces. Informing his partner of the discovery, they supplied themselves with tools, and
returned to the spot where the three-ounce
specimen wss found, and proceeded to clear
the clay awsy for a distance of two and a hslf
feet in length and nearly two feet in width,
which was as far as the gold could be traced.
The gold lsy nesrly fist the whole of this distance and on the bed rock. If it had been
melted and poured out it conld uot have been
so nicely laid as it was there. Some portions
of it was as thin ss a wafer, and none of it
thicker than a twenty dollar gold pieoe. Our
informant says if it hsd been taken out ss he
ssw it, it would have been the most beautiful
specimen ever exhibited in the world. The
owners on seeing the sight became excited and
anxious to ascertain the result of their discoyery commenced picking it out every way, thus
spoiling the beautiful specimen. Its appearance seemed to indicate, at first sight; ' that it
was @ massive boulder of gold, and ou
the surface it looked
as though there was
a blook of gold
worth ‘millions of
dollats.> They, dug
it out in pieces of
various sizes, and
the total value of the
gold was $3,0U0.
The most sinular
psrt of it was, there
was no quartz in it,
although the hill is
full of quartz,
Some people may
think that this was a
‘“ salting process,”
in order to effect a
sale for s large sum
of monty. But we
know that such is
not the csse, as the
greund in thatlocality is not for sale.
Furthermore, many
suoh pockets Lave
been found on Ked
Hull, one of wh.oh,
discovered many
years ago, yielded
over $7,0UU, and
others valying from
$50 to Pi,UUU. Asa
rale, these ** pocket
claims’ are not remunerative, from
the fact that when a
“‘nocket’’ ia stiuck,
miner’s will otten
spend twice asmuch
as the amount taken
out in trying to find
another, and then
be disappointed; and
Red Hill is not an
exception. Large
amounts of money
have been tsken out
of this hill, and a
great deal been
spent in prospectae But ra think
the time not fsr distant when it will be
demonstrated that one of the richest quartz
ledges in the country runs through Red Hill,
which when developed, will add greatly to the
wealth of Nevada county. All through the hill
floating quartz and spurs may be found, and as
the famous Schmitt ledge is close to and runs
in that direction, there is good reason for the
belief that Red Hill will yet be made tounesrth
her hidden treasures, and reward the faithful
prospector for his untiring energy.
Assayinc Leap Orzs.—Previons to reducing
the galena or other lead oro tothe metallio state,
A. Maseazzini converts the lead present in the
ore into sulphate, by igniting itin a porcelain
crucible with sulphate of ammonia, after which
the ore is treated in the usual manner. The
flux preferred by the author is that reoommended by Plattner, consisting of 13 parts of
carbonate of potasss; 10 of dry csrbonate of
soda; 5 of previously fused borax; and five of '
well dried starch.
Anti-SEa-Srcx Canmys.—The famousBessemer ship has encountered a rival in the floating oabin devised by a Russian. The constraotion is very mnch the aame as that of the Bessemer but the csbin instead of being attached
to a pivot, literally floats amidships between
the engines. The invention has been tested
by the Grand Duke Constantine, and is deemed
successful.
