The climate we are seeking is not a tropical one. Whoever associates Mexico with the characteristics of heat, malaria, venomous reptiles, has received a wrong impression of it. Such places, with their drawbacks, exist within the geographical limits of the country, but it is wholly unnecessary to seek them; for the towns of historical and picturesque interest are above the reach of tropical dangers, for the most part, while there are seasons of the year when even the warmer portions can be visited with safety and delight. At Orizaba the climate is temperate, fresh, and cool, beginning to have the elements of mountain altitudes. It is well to stop here for a day or two to become accustomed to the rarer air. It is a summer place of recreation for the inhabitants of Vera Cruz, while in winter it is a favorite excursion from the places higher up on the plateau. As we are travelling only in imagination, we may safely, without pause, press upward to the great plateau where most of the scene is laid of our story. For Mexico, with the exception of the narrow border of sea-coast we have just crossed, is a lofty table-land between two oceans, a mountain ridge continued up from the Andes in South America, contracted at the Isthmus of Panama to a narrow chain of granite, to grow broad in Mexico as it stretches to the northwest, until it spreads, at an elevation from 4,000 to 8,000 feet, almost from ocean to gulf. This is Anahuac, the so-called table-land of Mexico, a broad plateau upon which the picturesque romantic drama of Mexican history has been played. Upon this high plateau, which is by no means level, rise the crests of the great volcanic ridges, of which the highest are Popocatepetl and Istaccíhuatl. The table-land rolls off northward at first, keeping its high level, growing narrower, gradually sinking as it approaches the Rio Grande, until at the boundary line of the United States it has fallen to 3,000 feet. Thus Mexico possesses three well defined climates, due to variation in altitude: the _tierra caliente_, or hot lands of the coast; the _tierra templada_, or temperate region; and the _tierra fria_, the cold regions of the mountain tops, more than 6,000 feet above the level of the sea. These climates, moreover, are modified by the latitude, so that between the cold altitudes of the northern portions, and the warm tropical levels of the south, there is a vast range of atmospheric change. Our story has its stage, for the most part in the _tierra templada_, where the year is divided into two seasons: the dry season, from November to May; the rainy one, from June to October. The pleasanter one is the rainy one, in spite of its name. The rains are not continuous, but fall usually late in the afternoon and during the night, leaving the morning bright and clear, and the air deliciously fresh and cool. All the year roses bloom in the city of Mexico, and there are places where you may eat strawberries every day in the three hundred and sixty five.
