Excerpt: ... the multiplicity of causes which produce them, were sensible of the extreme difficulty of banishing entirely this evil from the process of forming the silk into skeins. To attain that end, it would be requisite to have winding-mills executed with mathematical accuracy., There can be no hope of this as long as the construction of those mills is left to country workmen. These unskilful artists do not see the marvellous effects of preciseness in the adaptation of the different parts of this useful machine. They know nothing of the proportions upon which the perfection of the winding-mill depends. Their mills, grossly constructed, without the aid of rules, or of any thing like principles, make only a bad and unsightly silk. It would be a lasting benefit to our country, if in every province whose inhabitants are engaged in raising silk-worms, there were established a manufacture of winding-mills, directed by an intelligent and scientific man; and that by a strict law, no machine should be delivered to a purchaser without having been previously examined, piece after piece, by the Director of the manufactory; that a statute, under a heavy penalty, should restrict every one to the purchase of his mill from the authorized manufacture of the Province; or, if made elsewhere, that it should pass inspection, and receive the certificate of the Provincial Director before delivery. By patronizing such an esta blishment, the French would soon succeed in ma king a silk as beautiful, and perhaps more perfect, than that of the Piedmontese. No nation of Europe has contributed so much as the Piedmontese, to improve the mill for the winding of silk; but this machine did not at once reach the perfection which it has now attained.
