CURIOUS AND scrEy1 - go =s s

toc has just patented an improvS So'
in weaving bags without any
seam. 1t does this by having -
sheds of warp, and the shuttle car y
ing the weft passes through one she
and back through the other. This ha
been done for some years in this
country; it is therefore difficult to see
of what avail the English patent can
be If contested.
SILK IN AUsTRALIA.-The Accli-
matization and Agricultural Societies
of Great Britain have been directing
their attention to Australia as q coun-
try supposed to be well adapted to the
cultivation of silk. IL Is now an
nounced that specimens of Japanese
cocoons, with eggs, implements, ETC.,
have been forwarded to Sidney by
Sir Henry Parkes, from Yokohama,
and experiments to test the adaptation
Of the country to silk growing will at
once be instituted.

PRESERVING WooD.-A New Or.
leans inventor has patented a process
for preserving wood, which is des-
cribed as consisting in treating the
wood with rosin. 1t is claimed to
protect wood not only from decay, but
from insects ald the teredo Iavals, so
that ships bottoms, if made of wood
so prepared, need not be coppereJ
Cross-ties for railM ays are preserved,
it is stated, for cents each, which il
cheaper than can be done by MANY
other processes.
PROPELLING STREET TCARs.-A New
Orleans inventor thinks he has solved
the problem OF street car propulsion
by the use of a tracting rope worked
along the track, either above or under
ground, the rope to be moved by the
fraction of the rope upon the traction
wheels. The rope engages the wheel,
in the following manner:-Three
wheels are used and the rope passing
under the two out side ones of the
group passed over the centre one,
making a loop which holds very
strongly. We see very many practi.
cal difficulties in this plan, and do not
believe it can he successfully worked.
a New THEORY or CoLoR-The
three primary colors were formerly
thought to be red, blue and yellow.
1t has been lately disputed that this
is correct, and recent experiments
have been performed to show that the
real primaries are red, green, and blue,

new theory that yellow NAV DE uro.

SOMETHING New IN TIE CANDLr
IRADE.-A London firm proposes 10
Introduce into market a novel firm,
candle. According to the Scientitin
Review, they-"form lateral anertnros
near the lower ends of candles, COM
munlcating from the outside with
internal longitudinal passages, which
IN issuing in close proximity to the
ilame, will produce more perfrct
combustion, and thus increase thn
luminosity of the candle. The lateral
apertures may be formed either bv the
ald drilling instruments, or by anv
other suitable means; and when the
candles have enlarged, ribbed, or
grooved lower ends, the apertures
may conveniently be made in tbe
grooves thereof. The lonpitudinaI
passages may extend either nearly up
10 tne tCp OF the candle, or they may
pass iiShl lulouSu Lne candle,
IMPROVEMENT IN CARrErs-Ac,
cording to the American Artisan. two
Philadelphia inventors have patented
all improved carpet. 1t is thus de.
scribed:-"The carpet is composed of
warp threads, and alternate thick and
thin filling of welt threads usually EN-.
ployed in making carpets of this class
The warp threads, however, in nro.
ducing the improved carpet, are raised
in couples for the thick filling and
slhgly for the thin filling, as fflIv w ex.
planned hereafter, SO that the fabric
may be more compacted in texture
and may have finer surface thar
ordinary damask carpet, without the
consumption Of more material than
the latter requires. The sound part Of
this invention, consists in the iIse NJ
certain shafts in combination with
the jacquard, whereby the warn
threads may be raised singIy. whilst
the jacquard raises the warp in COUPLES
alternately" P'''
