An 1838 French treatise by Gaillard, a nurseryman at Brignais near Lyon, on pruning and cultivating mulberry trees for silkworm leaf production. It argues for pruning in March at the start of sap flow instead of summer pruning, and covers planting, yearly care of young trees, spacing, old trees, wild, Moretti, dwarf and multicaule mulberries. A closing section gives observations on rearing silkworms, including temperature, ventilation and examples of cocoon yields. It has no weaving content.
