the properties of timber known to.the public, but not of iron. T.
resisting properties of iron, worked into every shape, and lor every
purpose, has not yet obtained the attention of persons concerned in
maritime affairs.

In marine boilers a regard is paid to place plates, made of suit-
able iron. in situations most exposed to the flame, and should an
understanding among interested individuals take place, to explore
the point in question, it may appear that expensive iron does not
offer the greatest resistance to the action of sea victor.
It has been ascertained that one piece of cable bolt reduced 250
per cent., while another piece reduced 100 per cent. Each piece
had the manufacturer's stamp cAni.s upon it At the same time a
third piece, made of the very best iron, for the occasion, was ope-
rated on, the reduction in which amounted to very little within
that of the better cable bolt.

It is remarkable, in this age, when improvement in all other ma-

be a solitary exception.

LIVERPOOL. CORN EXCHANGE, —This DAY

(From Messrs. R. MAKIN & SONS' Circular.)
The duties for the ensuing week are advanced to 24s 3d on
foreign Beans, to 22s 9d on Pease, and reduced to 18s
quarter on Rye, remaining unvaried upon all other produce ,
these periodical changes we continue to notice, although in-
dependent of the prospect of an early alteration to a reduced
scale, the high rates of duty attained for some time past
have rendered them almost entirely inoperative.

Notwithstanding the wind has remained contrary, the ar-
rivals into this port since Tuesday'contain a fair quantity of
Malt and Barley coastwise, a few cargoes of Oats from Ire-
land, and upwards of 9000 quarters of foreign Wheat,
chiefly from France and the Mediterranean.

The transactions in any free articles of the trade during
the same time have been light; but having experienced re-
peated inquiries for bonded Wheats, several parcels on the
spot have found bvyers, as well as one or two cargoes to ar-
rive, at prices somewhat higher than were previously obtain-
able.

Upon a very small number of country millers this morning,
and our local buyers still showing no disposition to increase
their stocks beyond their immediate requirements, the sales of
all descriptions of free Wheat were very moderate in amount,
at prices in some instances scarcely equal to, and in others ra-
ther under the rates of Tuesday.—Bonded Wheats, however,
co ntinued to command attention, and several further opera-
tions having taken place, the sales within the last three days
comprise two parcels of French at 6s. Bd. to 6s. 9d., one of
Egyptain at ss. 3d., and one of hard Odessa at ss. 6d. per

701bs. in granary; with a cargo of Polish Odessa afloat at

465., and one of Ancona at 495. per quarter, including cost
on board and freight.

English, Irish, and foreign, duty-paid, Flour, having met
with but little notice, barely maintained our last quotations.

Barley, Beans, and Pease sold with little difficulty, and in
small quantities only realised their previous value ; Malt, on

he contrary, was in fair request, and fully as dear as of late

Oats, being rather more plentiful,:were offered freely and
were the turn cheaper; and Oatmeal, in the absence of
country demand, was somewhat depressed in value.
