Córdoba also possesses large forests, as yet chiefly exploited for building timber and firewood. RIO CUARTO, on the river of that name, is the next largest town in the Province in point of population, but it is likely soon to be altogether surpassed in importance by BELL VILLE, on the Central Argentine Railway, a rapidly advancing centre of the cereal trade, and some day also, probably, by MARCOS JUAREZ, comparatively close to it on the same line. Goats abound in the North of Córdoba. Land values have increased and are increasing; especially in the most fertile regions in the South-Eastern parts of the Province. Córdoba has given and continues to give much attention to irrigation and possesses one of the largest semi-natural reservoirs in the world, certainly in South America, in the DIQUE SAN ROQUE, which is formed by means of a wall of masonry placed across the mouth of a mountain gorge. Its capacity is 260,000,000 cubic metres, and its operation is completed by a basin situated some fifteen miles from and below it, from which the water flows through two great primary canals. The area so irrigated is some 130,000 hectares. Other large irrigation works are in course of construction, and more still are under consideration. Córdoba has also a large share of industrial enterprise, of which the chief are lime and cement works, ornamental and other tile manufactories, potteries, sawmills and butter factories. The hills of this Province have some practically unexploited mineral deposits. The area between the city of Córdoba and the Provinces of Santa Fé and Buenos Aires is covered with a close network of railway lines, in great contrast (as may be seen by a glance at the railway map) in this respect with the more Northern parts of the Province. There has for a long time been talk of a canal to run from near the city of Córdoba to a point close to the port of Rosario, utilizing the surplus waters of the Primero, Segundo and Tercero Rivers. There is something almost incongruously prosaic about the naming, 1st, 2nd, 3rd and 4th, of the rivers which traverse a Province in which so much of the old romantic atmosphere lingers. The Alfalfa fields of Córdoba are in extent second only to those of Buenos Aires, covering an area equal to more than half that devoted to this forage in the latter Province. ENTRE RIOS This Province is bounded on the North by the Province of Corrientes, on the West and East by, respectively, the Rivers Paraná and Uruguay (hence its name “Between Rivers”) and on the extreme South by the River Plate, which is formed by the conjunction of the Paraná and Uruguay. As has been seen, Entre Rios comes second among the Argentine Provinces for production of oats; but in respect of other cereal crops it is still far behind Buenos Aires, Santa Fé and Córdoba. It is, however, rich in live stock, having nearly three times the quantity possessed by Córdoba. In point of population it ranks fourth among the Argentine Provinces.
