The first installment of a three-part treatise on silk and silk culture, printed in De Bow's Commercial Review in 1847. It argues for developing silk production in the United States, then traces the origin of silk in China, including the legend of Empress Si-ling-chi, and its introduction to Constantinople in 552. Most of the text describes Chinese methods drawn from Chinese sources and a Chinese informant: mulberry cultivation, egg preservation, feeding rooms and ovens, the worm's likes and dislikes, and cocooneries. Engravings show a round cocoon room (touan-tso) and a cocoon-raising frame (chan-po).
