In 1522 Cortes appointed officials to introduce sericulture into New Spain (Mexico), and mulberry trees were then planted and eggs were brought from Spain.
These men, returning to their various districts, impart to others the instruction they have received, and thus spread through the regions adapted to sericulture the proper methods of selection and rearing.
The fact that sericulture was in India first estalished in the valley of the Brahmaputra and in the tract lying between that river and the Ganges renders it probable that it was introduced overland from the Chinese empire.
The art of sericulture concerns itself with the rearing of silkworms under artificial or domesticated conditions, their feeding, the formation of cocoons, the securing of these before they are injured and pierced by the moths, and the maturing of a sufficient number of moths to supply eggs for the cultivation of the following year.
Mulberries are grown on many farms for silkworms; sericulture is encouraged and taught by the state, and over 1 00,000 lb of cocoons are annually exported.
