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.
It is a tropical region of foliage, flowers, and fruits, of rugged countryside and rushing streams, this eastern slope of Mexico; and the blue sky and flashing sun form the ambient of a perpetual summer-land. We traverse the sandy Tertiary deserts of the coast, and thence enter among groves of profuse natural vegetation, interspersed with cultivated plantations. In these the gleam of yellow oranges comes from among the foliage, and the graceful leaves of the plátanos and rubber-trees fan their protecting shade over young coffee-trees. But away from the haunts of man along the littoral is a region of startling beauty—of rivers and lagoons and hills, their shores and slopes garmented with perennial verdure, the forest-seas bathing the bases of towering peaks. Beautiful birds of variegated and rainbow colours, such as Mexico is famous for, people these tropic southern lands of Vera Cruz. Along the shores and in the woods and groves, all teeming with prolific life, which the hot sun and frequent rains induce, the giant cranes and brilliant-plumaged herons disport themselves, and gorgeous butterflies almost outshine the feathered denizens. From the tangled boughs the pendant boa-constrictor coils himself, and hissing serpents, basking crocodiles, and prowling jaguars people the untrodden wilds of jungle and lagoon. In these great virgin forests tribes of monkeys find their home, and the tapir and the cougar have their being. Mangroves, palms, rubber-trees, mahogany, strange flora, and ungathered fruits run riot amid this tropical profusion, and flourish and fall almost unseen of man. And here the malarias of the lowlands lurk—those bilious disorders which man is ever fighting and slowly conquering. This is Mexico's tierra caliente.
But our way lies onwards towards the mountains. A wildness of landscape, unpictured before, opens to the view. Here rise weird rock-forms, Nature's cathedral towers and grim façades magnificent in solitude and awe-inspiring, as by steep bridle-paths we take our way along the valleys, and draw rein to gaze upon them. Ponderous and sterile, these outworks and buttresses of the great Sierra Madre rise upwards, fortifications reared against the march of tropic verdure beneath, cloud-swathed above and bathed below by forest-seas. Born in that high environment of rains and snows, rippling streams descend, falling in cascades and babbling rapids adown romantic glens, and their life-giving waters, with boisterous ripple or murmuring softly, take their way over silver sand-bar and polished ledge of gleaming quartz or marble, winding thence amid corridors of stately trees and banks of verdant vegetation, to where they fill the irrigation-channels of white-clad peasants, far away on the plains below.
Still onwards and upwards lies the way. One of the most remarkable railways in the world ascends this steep zone, and serpentines among sheer descents to gain the summits of abrupt escarpments, from which—a remarkable feature of the topography of the eastern slope of Mexico—the traveller looks down as into another country and climate, upon those tropical valleys which he has left below. This is the Mexican Vera Cruz railway.

Let us pause a moment and gain a comprehensive idea of the character of Mexico's configuration and climate. It is to be recollected that Mexico, like other lands of Western America, is a country of relatively recent geological birth. The form of the country is remarkable. It shares the topographical features of others of the Andine countries of America—of tropical lowlands and temperate uplands, in which latter nearness to the heat of the Equator is offset by the coolness of the rarefied air of high elevations above sea-level. This structure is the dominant note of the scheme of Nature in Mexico—as it is in Peru and other similar countries—and the anthropo-geographical conditions are correspondingly marked. The region first passed is known as the tierra caliente, or hot lands. Its climatic limit extends up the slopes of the Sierras to an elevation of some 3,000 feet or more, embracing the lowlands, hot and humid generally, of the whole of the Gulf coast and of the peninsula of Yucatan, all of which regions are subject to true tropical conditions—the dense forests, the great profusion of animal life, the wonderful abundance and colour of Nature, and in places the swamps and their accompanying malarias, shunned by the traveller. But yellow fever and malaria are much less dreaded now than heretofore. In the city of Vera Cruz and in Tampico the new era of sanitation, brought about by British and American example and seconded by the Mexican authorities, has almost banished these natural scourges.
Rising from the tierra caliente, the road enters upon the more temperate zone, the tierra templada, extending upwards towards the Great Plateau. The limit of this climatic zone is at the elevation of 6,000 feet above sea-level, and here are evergreen oaks, pine, and the extraordinary forms of the organ cactus, as well as orchids. It is, indeed, a transition zone from the hot to the cold climates, and the zone embraces the greater part of the area of Mexico. Rising rapidly thence up to and over the escarpments of the Sierra Madre and the high plains, we shall enter upon the tierra fria or cold lands, ranging from 6,000 feet to 8,000 feet above sea level. Above this rise the high summits of the Mexican Cordilleras, with their culminating peaks, some few of which penetrate the atmosphere above the limit of perpetual snow. Thus, three diverse climatic zones are encountered in Mexico, which, ever since the advent of the Spaniards, have been designated as the tierra fria, tierra templada, and tierra caliente respectively. These conditions, as will be seen later, are also encountered upon the Pacific slope.
We now ascend the steep upper zone of the Sierra Madre, and cross it, descending thence to the Great Plateau or mesa central, the dominating topographical feature of the country. Here lies the real Mexico of history, and here is the main theatre of the new land of industrial awakening. Within the mountain ranges—that which we have crossed, and those which intersect this vast tableland and bound it on three sides—lies the great wealth of minerals—gold, silver, and others—which have attracted men of all races and all times since Cortes came. Here the true fairy tales of long ago, of millions won by stroke of pick, had their setting, and indeed, have it still. Upon these hills the thankful miner reared temples to his saints, and blessed, in altar and crucifix, the mother of God who graciously permitted his enrichment! And as if such devotion were to be unstinted, he also places his shrines within the bowels of the mines, and pauses as he struggles through the dark galleries, with heavy pack of silver rock upon his back, to bend his knee a moment before the candle-lighted subterranean altar.
