To help launch the American industry to make silk fabrics and become less reliant on foreign silk textiles the Secretary of the Treasury had published an instructional silk manual known as the "Rush Letter" in 1828.
As a beginning it provided instructions on rearing silkworms to make thread for textiles.
It was the first of a flood of informational books, journals and newspaper features on silk that circulated before the Civil War.
