There are two main travelled ways into Mexico. The first lies across the stormy waters of the Mexican Gulf to the yellow strand of Vera Cruz, beyond which the great "star-mountain" of the Aztecs, Citlaltepetl,[1] rears its gleaming snow-cap in mid-heavens, above the clouds. It was here that Cortes landed, four centuries ago, and it is the route followed by the tide of European travellers to-day. Otherwise, the way lies across the Great Plateau, among the arid plains of the north, where, between the sparsely-scattered cities and plantations of civilised man, the fringe of Indian life is spread upon the desert, and the shadowy forms of the _coyote_ and the cactus blend into the characteristic landscape. Both ways are replete with interest, but that of Vera Cruz is the more varied and characteristic. Here stands Ulua, the promontory-fortress, where more than one of Mexico's short-lived rulers languished and died of yellow fever, and which was the last stronghold of Spain. Beyond it arise the white buildings and towers of Vera Cruz, a dream-city, as beheld from the Gulf, of interest and beauty; and to the west, are the broad coastal deserts, bounded by the foothills and tropic valleys of the _tierra caliente_ of the littoral. Piled up to the horizon are the wooded slopes and canyons of the great Sierra Madre, topped by the gleaming Orizaba, towering upwards in solitary majesty. We stand upon a torrid strand, yet gaze upon an icy mountain. [Footnote 1: Orizaba, 18,250 feet altitude.] A country of singular topographic structure is before us. The Mexican Cordillera conceals, beyond and above it, the famous Great Plateau; the _mesa central_, running to the northwards eight hundred miles or more, and reaching westwardly to the steep escarpments of the Pacific slope. These plutonic and volcanic ranges encircle and bisect the great tableland, and enclose the famous Valley of Mexico and its beautiful capital, lying far beyond the horizon, above the clouds which rest upon the canyons and terraces of that steep-rising country to the west. Our journey lies upwards to this Great Plateau of Anahuac over the intervening plains and mountain range.
