THE BURRA BURRA EXHIBITION.

The South Aus*relien Mining Association's It toms,
King William-street, Adelaide, were thrown open to the
public on the 27th August, for the inspection of the speci-
mens of copper ore to be forwarded to the Exhtbition of all
NRII3OI in Londm, in 1651. The exhibition commenced at
11 and continued until 4 o'd,,ck. and in the course of that
time not less than from 400 to 503 persons attended. The
governor end Ludy Young and party came about 3 o'clock,
and there was a good sprinkling of ladies throughout the
whole day. The exhibition was conducted in the most
orderly manner, and the whole of the parties in attendance
were highly gratified, not only with the sight of the sped-
mons, but with the attention shown them by Mr. Ayers, the
wretnry, and Mr. Phillips, who had the specimens in
charge. The greater portion of the specimens were laid out
on four tables, a centre one, a cross one, and two side ones.
What most particularly attracted attention on the
first, were two splendid heaps of native copper, which
seemed to say, if ranch of this is found, the
smelter's occupation 'a gone. There were also some besu-
ttful specimens OR this table of almost every kind of ore
found at the Burro Burrs, of larger or smaller dtmenshns.
On the rose table there was • lag. r piece of ore, scord out
itt the middle, and sot unlike a large bird's nest in shape,
compared of almost every description of ore, but in which
red oxide, btu* and green e,rhona'es, and malschite pre-
vailed. The crystallisation, in the hollow of this mesa tort.
beautifal in the extreme. On this table also were erste line
sp, emelt, from the company's new mine, just opened at the
Emu Sprines, and called the Karkulto Mine, and a beauti-
ful Ideek of malachite, taken out of a new lode cut last
week in tilt, k's shat._ a. the Burro Burro. Both aide Wilms
ware e..,meec with specimens of nislaehi:e, red °aide, blue
and green carbmat,s, and other descriptions of ore, not
rqu dry showy, perhaps, hut of the very hest description.
At the entrance of the show room we obeerred a 154 x, cos-
t•Sring a large lump of b .awiful red oxide, apparently free
from all extraneous matter, of not less than from Kern to
tight hundred weight, and close by it two other boxes, con-
taining some rougher, but execotinslY good specimens of •

largesse, intended b ahvw ton isharalue-r of tie costar, out
of which therwera taken. Alwaether the exhibition was
of a first rate description.

PITMEN AND NiATIIEMATICS.—A paragraph has
appeared in the paper., ate lug the tact that the bo ,ILFPItt ra
at Newcastle bad observed that most of the standar:l ma-
thematical works were purchased by pitmen. Tm• fel;•'w-
ing anecdote is in point. Some pets since, a gentleman,
on his passage from Newcastle to Shields in a eteate-hunt,
went into the engine-room, and found one of the boGas
arenti:ned—namely, ...Emerson's Flexions "—lying on toe
table, rather black and smutty, evidently much r, ad. lie
asked the young enginemau who read th^ book ? Ile
answered that he did when he had time. Rather ourplised
, at the fact, and presupposing that he was a young mm of
seberiOr talent, be questioned him upon the subject,
stating that himself bad studied ti ese matters at the
university—had parsed, he believed, a fair examination—
and obtained a credible degree. With thin prelude they
entered freely into conversation ; ant from that time the
stranger used all his intimate to brio/ the studious sunniest-
man Into notice. The engineman is now a distinguished
nwhentatician, and the author of many of the very works
alludr d to. He had, a short time previous to this interview,
" risen from a bank-trapper to a bresksman" in a New-
castle coel•pit, as stated la evidence before the lords' cons.
mittes hot session ; and is now—Professor than, of Yang's
Colitge ?—Gateshead Observer.

NEW ALIMENTARY SUBSTANCES FOR THE PEOPLE.
—The French consul at the republic of Ecuador has
brought thence two alimentary plants of great import-
ance. The tuber of one, called Mau, hos the form of
an oblong potato: the interior of the substance, hoeever,
Las a red and yellow colour, and the taste is that of a ches-
nat. The older is called Millie°, and its form sal taws is
very Lear that of the potato. Both grow wild, and in ,treat
abundance, near Quito, even in the most meagre soil. Ex-
periments on their propagation are now being mane at the
Jardln des Planes. Paris.—The Builder.

ORDNANCE FROM BELGlCht.—Several iron guns,
east at Liege, and aleo some cases of iron, have arrived at
Woolwich by a veasel from Antwerp, the same hiving been
furnished by the Belgian (i)vernenent for her M,jesty's
service, and the Lords of the Treasury have issued the ne-
cessary directions to the proper authortiies of the revenue
for their delivery for the purpose stated.
FOREIGN CUTTLE.—The official returns of the im-
pute of foreign live stock into the metropolis from the whole
continentsl states during the p 'it year show a very camels-
. rable increase in the numerical amount of horned cattle over
the importations of the previous ye ,r, which had exhibited
1 a falling .0 in the number of those briateht in the year l°4B,
and therefore ;he arrivals of this astute during the year just
ended may be fairly stated to have exceeded tho.e which
have taken place during any previous year. This fact beir.g
established, it will be inter, Piing nod important to remark
in what particular these ieereav d arrivvls of horned be sate
from the continent have occurred. From close observation
of the various arrivals of this nature, we have found th.it
the urinals of horned beasts which, took place during a
heater year to some extent from France and also from If e'-
en's halo not been comie.:ed, although from the latter
state the supplies of the various description of mallet live
stock have been liberal and regular. We have no doubt
that the supplies of horned stock from Hunan I have been
considerably larger on the whole, as we have before re-
marked them to have been so individually, curing the past
I year, than on foresee °cessions, since the new tariff admitted
them free of duty ; but the important feature, on account of
its comparative novelty and relative retest, has hen the
extraordinary large supplies of horned beasts from Denmark
and the Unsettle B:atos, the former in particular, and
which his boon mainly instrumental in sweliiug the list of
importatiors of this nature.
FRENCH RAILWAYS.—The aggregate length of
'silvan open for traffic in France et the end of 1860 was
/ 9261tilometre. (1,819 miles), producing in that year 'woes
receipt of 04,267,941 f. (3,770.3171.), being ea average of
33,682 f. (1,3431.) per kilometre, or 3,1621. per mile. The
above length includes 1,296 miles ot 'saws,' a ample ed, upon
which the reetip a during 1860 amounted to 72.913,074 f.
(2,918,5231). being at the rate of 36,5161 (1,42014 per kilo-
metre, or 2,2861. per mile for the year. The sum expended
on these lite a smouuted to 32.738,2001, and the cost per
mile to 2-5,2221. I.l..duetieg 60 per gent. 170.1 the gram
receipts would leave 1,468,2611, ter dividend, which, on the
outlay, would amound to 445 per cent. the ge cost of
the English railways amounted at the end of 1850 to 35,2291,
per mile, sod the gross receipts for 1850 to 2 2d71. per mile;
showing that the eost of railways in Eogl.nd am 39 i per cent.
more than is France,
while the average receipts per mile are
greaier. With regard to the teeth, receipt* oa the Ireeci
lines in 1650, it may be mentioned that during the year 1843
a similar number of lades were open in the United Kingdom
for traffic, the receipts on which aimiunled to 3,4701 per
mile, bat swigs to the subsequent construction ..f numerous
branctes and coasp.ting awl the traffic per mile .become
reduced to the present amount. Should a simil.e course be
pursued with the railways in Fromm, the traffic receipts per
mile may be expected to &awes likewise.
