Oaxaca, the Pacific littoral state next adjoining Guerrero, is a region of much interest, both historically and topographically. The character of the Pacific coast has changed somewhat from those of the littoral states further north, in that there are no sandy plains bordering it, for the waves of the ocean bathe the very roots of the forest trees upon parts of the shore-line of this great state.

The area of Oaxaca is 35,400 square miles, and the population numbers some 800,000 souls, of which the white and Mestizo people take 330,000, the remainder representing the various Indian tribes. Due to its varied physical configuration, the state, notwithstanding that it is within the torrid zone, is subject to a variety of climate and temperature, from the heat of the coast with its occasional paludismo and fevers to the pleasant atmosphere of the temperate altitudes, and the ever-blowing cold winds of the Cordilleran summits. Here in this region the Sierra Madre forms a "knot" and ramifies greatly, the various branches breaking up the topography, and entering into the adjoining states. The central portion of the territory forms the divortia aquarum of the continent in the narrow portion embodying the famous isthmus of Tehuantepec, separating the waters of the Atlantic system from the Pacific. The numerous rivers of Oaxaca descend variously to the Pacific Ocean and Gulf of Mexico, the latter after traversing the State of Vera Cruz.

The scenery in places is grand and rugged, the mountain slopes are covered with thick woods, and the valleys with aromatic shrubs and bright-hued flowers, rich with animal life. Huge trees tower upwards, their giant limbs developed in a way such as only these tropical regions afford.

The agricultural products are similar to those enumerated for the neighbouring maritime states—wheat, barley, maize, and textile plants are produced, as also sugar-cane, cotton, coffee. The great forests afford oak, pine, cedar, mahogany, ebony, and other timber, and excellent natural pasturage abounds for cattle-raising, which is an important industry. The rich valley of Oaxaca is a favoured region, with a mild and healthy climate. To enumerate all the plants and products of this exuberant, tropical region would be to fill pages with names, but it may be said that almost every variety of tropical and temperate zone fruit, flower, fibrous plant, cereal, vegetable, and timber abound—a flora such as could not be surpassed anywhere. There are vast tracts of land in this state, of virgin country, consisting of pure alluvial soil, waiting population to cultivate it, and the whole forms an agricultural region of much promise.

Railway construction of late years has made the state a trans-continental territory. The Tehuantepec railway, elsewhere described, has its western terminus at the port of Salina Cruz, having traversed the state, and from this important route midway across the Isthmus a line of railway runs to Oaxaca, the state capital, and so connects with the main system of the Republic. Some years ago a serious outbreak of yellow fever occurred upon the isthmus, but improving hygienic measures appear to have prevented a recurrence of this, and to have diminished the almost inevitable malaria. There are other short lines of railway in the state.

The city of Oaxaca is handsome and interesting, and enjoys a temperate climate due to its elevation of more than 5,000 feet above sea-level. It justly prides itself upon having produced some of Mexico's famous men, including Juarez and Porfirio Diaz.

Chiapas is the southernmost of the Mexican states—the last upon the Pacific, its eastern boundary forming the frontier with the neighbouring Republic of Guatemala. Following out the general structure of Mexico's littoral, the Sierra Madre parallels the Pacific Ocean here, leaving a narrow coast strip, but with a lack of good ports and navigable rivers. On the northern side, however, the Atlantic watershed, the state is traversed by navigable streams which flow to the Gulf of Campeche, notably the affluents of the Grijalva and Usumacinta, traversing the neighbouring State of Tabasco.
