Encyclopedia article on the manufacture of silk from Rees's Cyclopaedia. It describes reeling raw silk from cocoons in Piedmont, then winding, throwing (twisting) and doubling to make organzine, tram and other thread types. It covers the Lombe silk-throwing mills at Derby, silk-throwing machinery such as the hand-turned 'oval' and the large circular mill, and the trade in Persian and Levantine raw silk. It also summarizes British import and prohibition statutes, refers readers to the article WEAVING for the weaving itself, and ends with an engraved plate of the machines.
