session of the kings Of Lahore, until the last
conquest of their kingdom by the English,
who left it at first in the Royal Treasury,
and since, at the breaking out of the last in
to Calcutta, whence it has just safely arrived
at Portsmouth.
This is the largest diamond known, always
excepting the Brazilian one, OF which there
are doubts as to its purity. When received
as present by Shah-Zehann, it weighed
nearly 800 carats.
The two next largest diamonds after the
koh-i-Nour, is the one upon which the eagle
OF the sceptre of Russia rests, which is also
diamond once belonging to the Grand Mo-
gul, and known by the name Of 'The Sun of
the Seas" 1t weighs nearly 200 carats.
The other is our diamond the Regent brought
from Madras by Pitt, the grandfather Of Lord
Chatham, and sold in l7l7 to the Regent,

GIGANTIC PRINTING PREss-The N. York
Sun has printing press in progress which
will throw off fifteen or twenty thousand
sheets an hour. II says -
The Mammoth Steam Printing Press now
constructing at the celebrated Machine estab-
lishment of Messrs. Hoe s. Co., for the New
York Sun, is in a forward state, and will be
completed in few weeks. The great in
crease in the circulation of our paper during
the last two years has rendered our present
printing facilities, although they are the most
perfect, entirely inadequate TO our wants.
In the fall Of last year we gave orders to
Messrs. Hoe, to construct for US, regardless
Of expense, machine that should entirely
surpass in rapidity of printing, and beauty Of
execution anything in the line of printing
machinery which the world has ever yet
seen.
The Messrs. Hoe pride themselves, and
justly too, upon the perfection with which
every work which they undertake is execut-
ed, and it may easily be supposed that nothing
will be spared to fulfil to the utmost our lib
eral order. Since the order was given, the
vast appliances of their far famed establish
ment have been employed in the produc-
ton, for us, of what will be when finished,
one of the most superb and important pieces
of mechanism ever devised by human in
genuity.
The machine will be capable of throwing
out from fifteen to twenty thousand copies Of
the New York Sun per hour, being an in
crease of nearly double the speed now attain
able upon our present lightning presses
The gigantic proportions Of the new press
will be understood among printers more es-
pecially, when we state that its entire length
will be thirty-three feet, and its height not
far from twenty feet. 1t will have eight print
ing cylinders, independent of the main type
cylinder; that is, eight places where the
sheets are drawn in upon the types. The
greatest number of cylinders now used is
four. The new machine will have eight
flyers, by which the sheets are caught and
laid even as they come out. Attached will
be counting apparatus by which the issue
ofevery sheet will be recorded in dial in
legible figures, showing the number Of sheets
printed for each edition, or during any given
space of time.
Such are the proportions of thissgigantic
machine, that Messrs. Hoe were obliged to
take out floor, and throw two stores Of that
part Of their establishment where the press
is making into one high room. Even the
great press-room of the Sun establishment is
not large enough to accommodate the new
occupant, and we shall be under the neces-
sity Of deepening it TO get the necessary
space.
The price which we pay for this machine
will not be far from twenty-one thousand
dollars 1t is the first one of the Kind ever
constructed, being very recent invention
When this wonderful specimen Of mechan-
ical skill has been finished, and put in op-
Grafton, our press-room will be thrown open
to the public, as It now constantly is, that all
may come in and witness its astonishing
operations, and admire the foresight and sa-
gacity of its great inventor-RoBERT M Hoe:
