Excerpt of seven pages (printed pp. 350-356) from a nineteenth-century household receipt book, giving detailed directions for raising silkworms. It covers choosing and hatching eggs with a schedule of temperatures, feeding through the successive ages and moultings, and managing heat and cleanliness. It also covers gathering and sorting cocoons, saving cocoons for breeding, moth coupling and egg preservation, baking cocoons, and pruning and planting white mulberry trees. The text draws on American experience, citing Pennsylvania and Connecticut.
