which the warp threads raised the blank part OF
each cald acts upon the levers, while the perforated
parts allow the levers to pass into the holes without
being affected.
In modification Of the jacquard machine, invented
by Mr. Samuel Dean. of Bethnal Green, London, an
attempt was made 10 dispense with the card Sips alto
setber by adopting tho use OF two revolving oars,
placed on opposite sides OF the machine Each OF these
bars has eight faces and the loom is actuated by two
tr,adles. The variations OF pattern are elected oy
temporarily stopping such holes in the revolving osrs
as will influence the raising Of those threads OF the
warp upon which the production of the patterns de
pends 1t was found, however that this modification
could only be applied to the production OF the sp eat
patterns, it being capable OF employing only sixteen
casts of the shuttle for their completion.
In 1880 another ingenious variation OF the jacquard
prreple was patented in England, in which the same
end was sought to be accomplished by marking the
DESIGNS by pins on rotating barrel instead OF by hoes
in A chain of cards. IL does not seem, however, TO
have been received with favor by the manufacturer
I'D TO within a very recent period the machinery
empioyed for the perioration OF the pattern on the
Jacquard cards occupied the labor OF TWO persons one
in reading off, the pattern, as IL Is termed anu tno
other IN arranging the punches. In Macknzes punch
inc machine. which was patented about four years ago.
an Improvement has been effected by which the person
who reads of the pattern is enabled t. work set of
keys like those of Piano Forte each of which inserts
punch into its proper place, thus dispensing WIN '"e
labor of A second workman
At the London Exhibition there were several looms
shown in which notifications of the jacquard prnci
ple were more or less successfully carried out one OF
them intended for figure weaving nad doupie JUG

Prize medals were awarded for several other new
notifications of the jacquard apparatus Tor looms and
lace machines to Messrs. Ackn in France, Bonqrdej
in Prussia and GAMBIA in Lombardy.
Tie most remarkable improvement, however, Oh tue
Jacauerd loom which has been suggested for our con
sheraton is that which has been announced TO I'd hs
having been Just effected in Italy by the application OF
electricity TO the operations of the weaver. This in
yention prof sses to do away with the use OF comp
Gated mechanism of pattern cards, and If we under
stend Alright, of machinery almost altogether That
electricity may be rendered important agent IN tho
production Of the pattern, We can readily imagine;
but that it will effect all that is promised in this az
rouncement we may reasonably doubt. As, however,
the details of the invention not as yet before n,
the preliminary steps having been only just taken to
,ccsfe the patents il would be Unfair TO raise any dis
CUSHION as TO the principles involved IN it, until wo
have an opportunity Of informing ourselves fully as TO
their merits .
Having taken a rapid review of the successive I'M
proyements effected in the construction OF the silk
oom, II now only remains for us TO consider il in com
bipaton with mechanical power. BY which the labor Of
the land has been in great degree substituted, and
the facilities of production largely increased.
Tie earliest invention Of loom for mechanical
weaving was we believe, that OF a Frenchman named
De Gennes, Who in 1878 constructed rude sort OF
weaving machine, int ended to increase the power
of the common loom. Toward the close OF the
sane century, the drawing and description OF q
power loom, almost indenticai IN construction
with the celebrated invention OF Dr Cartwnght'
were presepted to the Royal Society Of LONDON, but
here every reason to believe that this gentleman was
wholly unacquanted with the fact OF their existence
until after he published the details OF his discovery 70
tIe world His attention had been directed b. the sub
eet BY circumstances purely accidental, which occur
red during visit 20 Natock IN 1854, and although en-
tr,ly unacguainted at the tine with the COMMUNIST
processes used in weaving, by the April Of the follow
NJ wear he succeeded in producing his first power
