have a double fet of them, in order to prevent thofe 
delays which might happen by their breaking; be- 
caufe any delay in the reeling of filk occafions a con- 
fiderable detriment. 
Our happier conflitution doth not admit fuch 
rigorous laws as that of Piedmont. To make the 
common people adopt any new contrivance, they 
mult not only know that it is the heft, but they mull 
alfo feel that it can be eafiiy praCtifed. Thofe whG 
fuperintend public filatures in our colonies may in- 
deed, for the prefent, keep their workmen to the 
Piedmontefe reel ; but public filatures can no more 
produce large quantities of filk than public fpinning- 
houfes could produce the vail quantities of linen- 
yarn which are now raifed from private family- 
wheels : And when the management of filk -worms 
becomes more common in our colonies, and people 
find that, by reeling their own cocoons, their profit 
will be nearly doubled, and this with much lefs 
labour than was ufed in rearing the worms ; when 
this, I fay, fhall happen (and it is to be hoped itfoon 
will), then the making of the Piedmontefe reel more 
fimple, and more familiar to the common people, 
will I believe appear a thing of coniiderable import- 
ance to our filk manufactures. 
I fome time ago turned my thoughts to the effect- 
ing of this ; and fh ould before now have put them 
in execution, had I not diftrufted my own abilities to 
perform a thing, which the Piedmontefe themfelves 
had not attempted. I have now conftruCted a reel, 
which, without any additional mechanifm, performs 
the work of the Piedmontefe reel, and ufes but two 
wheels with teeth inftead of four wheels. It has
