on a pin fixed in the guideflick, the pin palling thro’ 
the nieh m. The other end of the fwivel M contains 
the flop-wires b b, and is attached to the end of the 
rod O, which projects from the front bench of the 
reel. This attachment is made by means of a piece 
of packthread with a knot on its end ; which pack- 
thread paffes thro’ a hole in the fwivel and in the 
piece O, and being fixed to a peg P, which turns in 
the under part of the piece O, is drawn to a proper 
degree of ten lion to allow the fwivel to obey all the 
motions of the guideflick. 
The manner of making the double croiffure is' 
thus : The two (ilk threads are paffed thro’ the two 1 
flop-wires b b , and thro’ the two guide-wires c c 9 , 
and fo are faflened to the reel. Then either of the 
two threads is taken in that part of it which lies be-- 
tween the flop- wire and and guide-wire, and turned i 
two or three times round the other thread ; and then ' 
each thread is placed in the groove of the pulley at hb,. 
taking care to place each in the groove of that pulley 
which lies on the fide of its own flop- wire. The 
threads will then appear in the fituation reprefented 
in the figure twilled round one another in the two 
points o and p. 
The* great advantage of this method is the taking 
off the preffure of the threads, by making them pafs 
over two pullies inflead of two hooks; and by the' 
fwivel complying with all the motions of the guide- ■ 
flick, which keeps the angles of the croiffure con-- 
flantly the fame : without this, the bearing of the 
threads and the variation of the angles will make 
them fo liable to break, that, from many experi- 
ments which I have made, I might venture to fay.
