oENRES PORCELAIN MANUFACTURE.-The choicest
specimens of porcelain wares produced at the
Sevres manufactures in France and as the process
there pursued is of much popular we'll as scien-
tlhc interest, brief account of it is here given-
Tender porcelain, or soft china-ware, is made with
vtreous frit, rendered less fusibe and OPAQUE by
an addition of white mari or bone-ash This frit at
Sevres is a composition made with some nitre a
little sea-salt, Alicant Barilla, alum, gypsum, and
much slcious sand or ground fnts. This MIXTURE
is subjected to an incipent pasy fusion in furnace
and thus very white spongy frt is obtained. 1t is
puverized and to every three parts of one of the
white mari of Argenteuil is added; and when the
whole well ground and intimately mixed the paste
offender porcelain formed As this paste has no e
nacity, it cannot bear working till mucilage of
gum or black soap be added, which gives it kind
OF Elasticity, though even then it will not bear the
lathe. Hence it must be fashioned in the press be-
tween two mouds of plaster. The pieces are left
thicker than they should be, and, when dried are
finished on the lathe with iron tools. In this state
they are baked without any glaze being applied
but as this porcelain softens far more during the
baking than the hard porcelain, it has to be sup
ported on every side; this being done by baking
earthen moulds all such pieces can be treated in
this way, such as plates, saucers, &c.
REVOLUTION IN THE RIGeING AND SrARnING OF
SHIPs-The ship Edward, of this port, owned by
Captain Barton Ricketson, and lying at Rotch's
Wharf, is now being rugged upon new principle,
which we understand has been patented by gentle
man in New York, Captain Lewis, who is superin-
tending the operations. The improvement, it is
claimed, will propel vessel faster, with less
Der of seamen and at less expense, than upon the
old plan. Masts and rigging are entirely dispensed
with In the place of masts, shears are to be erect
ed, forward and aft, brig fashion, two pair in each
place, and between each set of shears the yards
swing on piyots The bowsprit will also be done
away with. The ship, which is to be rugged as an
experiment, will probably be ready for sea in
couple of months, when we shall be able to give
fuller description of this novel rig which the in

The DUTCH ToLLs.-The treaty between the Uni
ted States and Belgium expires in August next
NO new treaty has thus far been negotiated. In
virtue OF clause in said treaty, Belgium undertook
to pay the tonnage duty which the Netherlands col
lect on all vessels arriving from sea which navigate
the Scheldt. These dues amount to one and half
forns per ton say about sxty-three cents. As, af-
ter August next, Belgium will no longer paw these
dues for the American shipping, our vessels will
have to pay this tonnage duty when arriving at
Antwerp, or at some lower point of the river where
the Netherand collection Office may be. The Sound
