Mexico combines all the climates of the globe. From the icy peaks of the Cordilleras, down to the burning coasts of the ocean, the traveller in that country undergoes every temperature. Hence this vast territory has been divided into three distinct zones: las tierras calientes, or hot lands, composed of the plains on the seashore, and which produce sugar, indigo, and cotton in truly tropical abundance; las tierras templadas, or temperate lands, regions formed by the Cordilleras, and which enjoy an eternal spring, great heat and extreme cold being equally unknown there; and lastly, las tierras frias, or cold lands, which include the central plateaux, and where the temperature is relatively much lower than in the other zones. Still we should remark that in Mexico the expressions "heat," and "cold," have not an absolute value as in Europe, and that the lofty plateaux, known as the tierras frias, enjoy a temperature like that of Lombardy, which would seem to any European a very pleasant climate. Owing to its position, Guadalajara shares in two of the three zones that divide Mexico. Situated on the limit of the tierra caliente and the tierra templada, the tepid breezes and pure sky reveal the warm regions of the seaboard, which extend thus far. The arid sands are succeeded by fertile and well-cultivated plains, fields of sugar-cane, Indian corn, bananas, goyaviers, and other productions of the tropical flora. By degrees the gloomy black oaks and pines, which only grow on the mountains, become rarer, and eventually disappear entirely, to make room for poplars, fan-palms, calabash trees, sumachs, Peru trees, and thousands of others, which proudly wave their superb crowns over the spontaneous vegetation that surrounds them.
