$9 as to take two threads to a dent, equal 
to sixteen score of dents for carpets or 
rugs three feet in width. The hand- 
shuttle, and other apparatus, are made in 
the usualmanner. ‘The warp is in gene- 
rai dressed with starch, made of flour and 
water, aid in the beaming it is received 
throueh a nddie with iron teeth. The 
shutice is worked by hand. The harness, 
consisting of four wings when at work, 
two wings being UP» and two down, parts 
two chaius in haif every time the shuttle 
passes through the centre. The pile is 
raised by means of a rod of iron, or other 
metal, with a groove of about three-eighths 
of an inch; round this rod the e sun-yarn, 
dyed and prepar red tor the pile, is wound 
by the hand, bemeg threaded through ev ery 
two threads of the war p, and when struck 
up by the batten, is cut with a sharp in- 
strument down the groove of the rod; by 
which means the rod is immediately ex- 
tricated from the dyed sun-yarn, the cut 
ends of which form the pile on the upper 
side of the carpet, or rug. The shoot 
forms the eround or back, and the carpet 
is firdshed by chipping and trimming the 
pile with a pair of shears.

through a sieve, so that the stone and 
the sand may be in about equal propor- 
tions. Of this powder take six gallons, 
and add to it a quart of lime recentiy 
slacked, and a pint of the powder of 
burnt bones. These materials are to be 
dried in a boiler, and then two gallons of 
tar to be added, and the whole boiled to” 
a sufficient degree of hardness. When 
boiled, it may be toughened by beating 
into it hair, hemp, or any other such ma- 
terial, in the same manner as hair is usu~ 
ally mixed with mortar, when.used for 
facing upright work, It must be mount- 
ed on paper, cloth, or similar substances. 
To form it into sheets, a sufficient 
quantity is worked into a long roll, on a 
sheet of lead; this must be kept warm by 
means of a hot plate, under which the 
flue passes, to convey the heated air 
from the furnace ; then beat it into a flat 
sheet to the thickness required. A board 
of sufficient size, to receive the sheet 
when finished, is passed through the rol- 
lers from behind; the nose of the board 
is chamfered away, so as to pass readily 
under the lead bearing the composition. 
The board bearing the composition on 
the lead is then passed back between the 
rollers, and comes out on the back side. 
of the press, where are fixed cutters, 
which are turned round by a pinion, tak- 
ing in the great pinion whith carries the 
rollers. These cutters slide on the har, 
and may be put more or less apart, ac-- 
cor ding to the size of the sheet.
