ranch of Tlamacas; it is sold in Mexico and Puebla at the same price as that of Sicily—that of Popocatepetl being superior in quality. The snow, too, on the side of Ozumba, is exploited, but this exploitation is on the smallest scale.
Various expeditions have been organized for the ascent of Popocatepetl, some scientific in nature, others for amusement. The first was made in 1519 by Diego de Ordaz, one of the soldiers of Cortes; others followed. In our own day, such expeditions are frequent and their results happily verify each other.
Ixtaccihuatl,—“white woman”—connected to Popocatepetl by a ridge of graceful outline, rises to 5,288 m. altitude above sea-level. Down the slopes of this mountain, several torrents, derived from the melting snows, pour and form cascades and falls up to forty-five metres in height. These same slopes, covered by a sheet of astonishingly rich and luxuriant vegetation are gashed by deep crevices, in which are enormous masses of porphyritic and basaltic rocks. Conifers form dense forests up to 3,000 m. altitude; from there the vigor of arborescent vegetation diminishes and at 4,000 m. it completely ceases; from that point on there are only stretches of brambles, which completely disappear at about 4,200 m.; then follow the sands, and, lastly, the perpetual snows, which begin at 4,300 m.
The crest, which is very grand and beautiful, resembles in the arrangement of its rock masses, the form of a woman’s body, stretched at length upon its back, and covered by a white winding sheet. From this, the name of white woman,—izta, white; cihuatl, woman—with which this lovely mountain was baptized by the dreamy imagination of the Aztecs.
