A U.S. House document of 1828 in which the Secretary of the Treasury, Richard Rush, transmits a manual on silk growing and manufacture prepared in response to a House resolution of 1826. It opens with the Committee on Agriculture report and a history of silk, including silk culture in the United States. It then covers silkworm natural history, mulberry cultivation, rearing in each age, diseases, cocoon preparation and reeling, and silk throwing and twisting. Later sections describe silk looms, draw-boys, ribbon and power looms, and patents, followed by silk dyeing treatises and engraved plates.
