The first serious operations of the whites date from 1804 ; but they have frequently been interrupted by the civil wars, or by the high-handed proceedings of the military commanders. The mining region, in a pre-eminent sense, occupies the southern part of the Sierra de Famatina, the richest veins lying on the crests themselves near the central peaks at altitudes of from 13,000 to 15,000 and even 16,500 feet. Those of La Mejicana are said to have been discovered by some Mexicans by following to its source a stream charged with ochre. The limestone rocks of which these mountains are formed are intersected by innumerable metallic veins, pyrites of copper, gold, and silver in association with chlorine, iodine, arsenic, and sulphur. Between 1820 and 1860 these gold and silver mines yielded £1,200,000, Fig. 17L—Chilecito and Famatina. Scale 1 : ,000. West oF Greenwich 15 Miles. which was partly minted at La Rioja. At present operations have been extended to the copper mines, in which the ores contain about one-sixth of pure metal. Chilecito is connected by a branch line with the Argentine railway system, which gives access to the difficult tracks running from various points over the moun- tains. By one of these routes, which leads through Vincldita to the Upper Vermejo valley, Chilecito maintains active relations with the mining centre of Copiapo on the opposite (Pacific) slope of the Argento-Chilian Cordilleras.

South of Rioja follows the province of San Juan, which is also a mining district, and which, like Catamarca and Rioja, lies entirely wathin the region of closed river basins. <S'«/t Juaii^ the capital, is well situated at an altitude of
