Or tHe SILK-WORM. 365 
confifts the greateft difficulty, is to wind even, becaufe 
as the cocon winds off, the end is finer, and you mutt 
then join other cocons to keep up the fame fize. This 
difficulty of keeping the filk always even is fo great, that 
(excepting a thread of two cocons, which we call fuch) we 
do not fay a filk of three, of four, or of fix cocons, but a 
filk of three to four, of four to five, of fix to feven cocons. 
If you proceed to a coarfer filk you cannot calculate fo 
nicely as to one cocon more or lefs. We fay for example, 
from twelve to fifteen, from fifteen to twenty, and fo on. 
It is eafy to conceive, that it is more difficult to wind a 
coarfe filk even, than a fine one, becaufe it is harder to 
keep a great number of cocons always to the fame fize, 
than a {mall one. 
The dupions which you defign for rondelette, or ordi- 
nary fewing filk, are to be wound from fifteen to twenty. 
The reft you may wind as coarfe as poflible, i. e. from 
forty to fifty: they ferve to cover and fill up in coarfe 
ftuffs, and may likewife be ufed for fome fort of fewing filk. 
The good choquette is to be wound according to the 
ufes to which you intend to apply it; however not finer 
than from feven to eight. The bad choquette you may 
wind from fifteen to twenty cocons. 
In winding the good cocons, you will always meet with 
fome defective, which will not wind off, or are full of 
gouts and nubs. Thefe you muft take out of your bafon 
and keep by themfelves. They are called ba/inats. They 
are to be wound apart as coarfe as youcan. They make a 
foul, dirty filk. To have a good filk, you muft wind in 
fine weather. If the wind be high it fhakes your filk, 
and prevents its lying fmooth on the reel, forms {trings 
of threads, which make it very difficult to wind on bob- 
bins. If the weather is rainy the filk is damp, and has 
not that luftre it ought to have, or which it has when it 
dries, as it goes upon the reel. You muft mind not to 
hank it when damp, but let it dry on the reel; otherwife it 
would be furzy.
