That such enormous mineral resources should have as yet yielded no greater results is easily explained. The Roman and Moorish workings, although traditionally of fabulous yield, are of small depth, owing to insufficient machinery for pumping. Till the present century, the working of mines was forbidden by the Spanish Government, with the object of favouring the development of the American colonies. The mining laws of 1825 and 1849, suddenly placing the acquirement of mines within the reach of every substantial peasant, produced a fever of speculation, and a recklessness in the application of unskilled labour, which naturally conduced to the discouragement of mining enterprise, while the recurring civil wars excluded foreign capital and skill. Spaniards have a mania for erecting smelting-works on the mines, a practice occasionally justified by difficulties of transport, but which has caused much loss of capital through inherent difficulties and want of metallurgical skill. Endless litigation, arising from the defects of the first mining laws, and the inexperience of the surveying engineers, contributed to ruin the small capitalists who had attempted to work the mines. Foreign capital is now the chief requirement. The existing mining law, greatly improved since 1868, is the simplest in Europe; the expense of a concession is almost nominal, and the royalties on ore are extremely moderate. Large mining adventures in Spain rapidly develope industrial conditions and profoundly affect the habits of the population. Even in times of civil war a _modus vivendi_ between the conflicting parties can be more easily secured than might be expected. The development of means of transport, already considerable before the last Carlist war, is being seriously resumed under the present Government. The Spanish peasantry, when suitably treated, will be found a fair-dealing, intelligent, and industrious class. It must, however, be remembered that in the peculiar physical, political, municipal, and fiscal conditions of Spain, no mining enterprise can safely be undertaken without thorough investigation of all the external circumstances, claims, and prospects concerned; since more mining speculations have failed from inattention to such matters than from any disappointment as regards the quality or quantity of ore.
