THE LAGO CUTTING, RIO TINTO.

The Rio Tinto and the Tharsis have been rightly regarded as the show mines of Spain, and the former can, of course, hold its own among the leading mines of the world; and, if it is unlikely that any other Spanish property will rival this cupiferous wonder, there are many that, under proper scientific management, will be found to be as relatively rich and profitable. What is required in Spain is money for development and brains to direct the operations. The existence of minerals, and of copper particularly, has been demonstrated; and now that English capital is slowly but in steadily increasing amount being invested in these mines, a tremendous reaction in the industry may confidently be looked for in this quarter of the globe. Within the past year or two quite a number of promising properties have been acquired for the English markets, and in every instance the results of the opening-up work have more than realised the expectations of the proprietors. The company, which was formed a short time ago to acquire an extensive property at Coruña, is regarded by experts as a proposition of the highest importance. Another company, called the Escurial Copper Mines, is already working at a profit, and promises to give very large returns for many years to come. La Recompensa Mines also appear to be rich in copper, and the ore also contains precious metals, assays giving as much as 12 ozs. of silver and 9½ dwts. of gold to the ton. An important fact in connection with all these mines is that they are only distant two miles from the Escurial Mines; consequently the cost of ore treatment will be considerably reduced by reason of the proximity of large smelting works now nearing completion. The latest reports from the Huercal Copper-cobalt Mines, in the province of Almeria, all tend to confirm the very high opinion which the English owners formed of their value at the time they acquired the property; and the English-owned Rio Rimal Mines in the province of Gerona are putting out very fine copper.

THE CUTTINGS, RIO TINTO.

Among the other Spanish mines in which English capital has been invested—and attention will be mainly confined to these in this chapter—tin and silver-lead play a prominent part.

Although tin was smelted more than two thousand years ago, and some of the first ore containing the metal was probably discovered by the Ancients in that north-westerly province of Hispania, which the Romans named Gallaeci, Spain is not to-day ranked among the great tin-producing countries of the world. Pliny refers to Cornish tin, but most of the metal contained in the ancient bronze weapons and objects must have been derived from the Spanish mines. The ancient town of Orense, the capital of the Galician province of the same name, which was founded by the Romans, and greatly esteemed by them on account of its warm springs, is the centre of the industry, and the country is scored and bored with many indications of the enterprise and energy of the ancient miners. Beariz, a little village in the mountains of Balcovo, is situated on a hill that is tunnelled with Roman workings in what are probably the richest tiniferous deposits in the richest tin district in Spain. Enormous quantities of the mineral must from this mine alone have rewarded the labours of the pioneers, who were so rudely interrupted by the invasion of the victorious Visigoths, and no succeeding owners have mined the property on the same gigantic scale.
