"One can believe in absolute floral perfection," said the Journalist, "in a country which embraces all climates. 'So accurately,' observes Wilson, 'has nature adjusted in Mexico the stratas of vegetation to the state of the atmosphere, that the skilful hand of a gardener might have laid out the different fields, which, with their charming vegetation, rise, one above another, upon the fertile mountain sides of the table-land.' "Along with many other important vegetable growths, the cotton-plant is supposed to be indigenous to Mexico, as Cortez, on his first landing, found the natives clothed in cotton fabrics of their own manufacture. Its culture continues to the present day, but with very little improvement in method since the earlier time of the Spanish Conquest." "And now," asked the Harvard man, "since we are on the subject of Mexican natural floral products, may I speak my little piece, which I may call, 'What I have learned about the Cactus'?" The Koshare graciously assenting, Roger Smith thus began: "In Mexico the cactus is an aboriginal and indigenous production. Several hundred varieties are identified by botanists. A beautiful sort is Cereus grandiflora. As with us, this variety blooms only at night; its frail, sweet flower dying at the coming of day. The cactus seems to grow best in the poorest soil. No matter how dry the season, it is always juicy. Protected by its thick epidermis, it retains within its circulation that store of moisture absorbed during the wet season, and when neighboring vegetation dies of drought is still unharmed. Several varieties of cactus have within their flowers an edible substance, which is, in Monterey, brought daily to market by the natives. That species of cactus which combines within itself more numerous uses than any known vegetable product is known as the maguey, or century plant. "Upon the Mexican mountains it grows wild as a weed; but as a domestic plant it is cultivated in little patches, or planted in fields of leagues in extent. Its huge leaf pounded into a pulp makes a substitute both for cloth and paper. The fibre of the leaf, when beaten and spun, forms a silk-like thread, which, woven into a fabric, resembles linen rather than silk. This thread is now, and ever has been, the sewing thread of the country. From the leaf of the maguey is crudely manufactured sailcloth and sacking; and from it is made the bagging now in common use. "The ropes made from it are of that kind called manila. It is the best material in use for wrapping-paper. When cut into coarse straws, it forms the brooms and whitewash brushes of the country, and as a substitute for bristles it is made into scrub-brushes, and, finally, it supplies the place of hair-combs among the common people. So much for the cactus leaf; but from its sap arises the prime value of the plant.
