According to Humboldt, the insect is bred on a species of Cactus, (Opuntia, or Indian fig,) the fruit of which is white. The Cochineal feeds only upon the leaf. The process of rearing it is complicated, and attended with much diffi- culty : the leaves of the Nopal, on which the eggs are depo- sited, must be kept free from all extraneous substances, and in the Cochineal districts the Indian women are seen bending over them for hours together, and brushing them lightly with a squirrel's tail. In a good year, one pound of Semilla, deposited upon the plant in October, will yield, in December, twelve pounds of Cochineal, leaving a sufficient quantity of seed behind to give a second crop in May. The plantations of the Cochineal Cactus are confined to the district of La Misteca, in the state of Oaxaca. Some of these Haciendas de Nopales contain from fifty, to sixty, thou-
