=Buenos Aires=, the last, largest, and most important of the Provinces, with the greatest population, is the only one with an ocean front. Buenos Aires has on the north Córdoba and Santa Fé; northeast, on the other side of the Paraná and La Plata, Entre Rios and Uruguay; the Atlantic is on the east and south with a bit of Rio Negro, which with La Pampa is on the west, with a little also of Córdoba. The land is flat, but with two ranges of hills; the highest in one range is 1200, in the other about 3000 feet. Several useful, some navigable rivers flow towards the ocean. The country is agricultural and pastoral, especially devoted to cattle and wheat, but in the numerous towns, industries and manufactories are developing. Many great railway systems converge at the Federal Capital. There are good roads near most of the towns, which is not the case in the other Provinces, and good auto roads lead from Buenos Aires to Tigre and to La Plata. South of the Provinces, at least below Buenos Aires, is what was once called Patagonia, now divided into Territories. =La Pampa Central=, a Territory which extends farther north, is already from its population entitled to be a Province. Lying south of Mendoza, San Luis, and Córdoba, it has Buenos Aires on the east, Rio Negro Territory south, with the Colorado River as the dividing line; and west, Neuquen and Mendoza. The Territory is undulating, with hills, valleys, prairie, and lakes; the soil is generally fertile, yielding fine crops; wheat, corn, barley, linseed, alfalfa, vines, fruits. Large herds of cattle roam over the pastures but are usually sent out for fattening. =Neuquen=, south of Mendoza, borders on Chile, has Rio Negro south, and also with La Pampa, east. The north and east parts are arid, but the west mountain section has fine fertile valleys and forests, with many rivers and lakes. A railway now making this section accessible, it will be more attractive to settlers. =Rio Negro=, first of the divisions of Argentina to stretch across the country, has Neuquen and La Pampa on the north, Buenos Aires and the Atlantic east, Chubut south, and Chile and Neuquen west. The section between the Negro and Colorado Rivers is fertile, also patches near other streams; wherever irrigated, good crops of wheat, corn, oats, and alfalfa are certain. Fruits and vines do well in the Negro Valley. Excellent timber is exported in beams and planks. There are some towns and many agricultural colonies; trade goes on with Chile in cattle and sheep. Several rivers are navigable and a railway has been constructed from the port San Antonio to Lake Nahuel-Huapi.
