6. AUSTRAL, composed of the territories of Rio Negro, Chubut and Santa Cruz. 7. RIPARIAN, comprising the islands of the Paraná, Entre Rios and the shores of the rivers Plate, Paraná and Uruguay. 8. MARITIME, stretching along the Atlantic coast in a belt three leagues wide, more or less, according to the configuration of the soil. 9. STRAITS, consisting of the shores of the Straits of Magellan and Tierra del Fuego. The confines of all these regions cross and merge into one another, at times, on account of the altitude in their different zones. The vegetation typical of one zone is often scattered through one or more neighbouring ones, so that they cannot be exactly defined. The greater or lesser altitude of a place often goes towards modifying the uniform character of the vegetation. In the first region the forests contain the best timber in the Republic, cedar or hardwood, so-called (cedrela) quebracho white and red, lapacho, algarrobo (carob), acacia, ibirá, molle, ñandubay, different woods, Misiones pine, Brazilian araucaria, tarco, urunday, aguaribay, cebil, timbó, palm trees, etc., and the fruit trees of the region, orange, lemon, pomegranate, guava, chirimoyas (custard apple) and pantas. Fruit tree planting, though seldom, is more carefully done than formerly, and its products inundate the markets of Buenos Aires, Rosario and Santa Fé. The Paraguayan tea tree, or rather bush (mate), is grown in many places and cultivated rationally. Mr. Thays’ experiments give room for hoping that this precious bush may become a certain source of future wealth, whereas the old system of cultivation was bound to entail, early or late, the total extinction of the product. All kinds of eucalyptus trees grow well, and the extensive planting of these trees in the Chaco, Misiones, in Tucumán, Corrientes and Santiago del Estero is a consummation devoutly to be wished for. The same trees are found in the second region, but fewer in number and smaller in size, orange, lemon, fig, plum, peach and pomegranate trees, also the vine can be successfully grown, and in the valleys guayavos, chirimoyas, pantas, avocados and persimmons. Plantations of mate and eucalyptus could also be tried. The third region is warmer and partly covered with vineyards. Here the vine is in its native element. On the slopes of the Andes the soil is admirably suited for the planting of forest trees, such as pines, firs, beeches, and all others peculiar to mild, dry climates; as well as for that of fruit trees, such as the walnut, chestnut, apple, cherry, pear and peach trees … the vine where late frosts are not very frequent.
