The Germans have introduced into their mines a regular military system, and the engineers, who are denominated captains, wear when in full dress a uniform of a very military appearance, set off by epaulets and gold embroidery. Not inferior to them, however, are the Cornish miners, their captains being those who have risen by their industry and intelligence from the lowest to the highest grades, although men of less education than their German brethren. The Spanish miners are a sober and frugal race, enjoying their cigarettes even while at work. On leaving the mine they put on their snuff-coloured cloaks and broad-brimmed sombreros. In the southern part of the Peninsula they wear grass sandals, cloaks of bright colours, and handkerchiefs bound round their heads. Leading lives of toil and hardship, their huts are wretched abodes built of stones and mud, their beds the ground, an iron or copper kettle hung from the roof above the fire in the centre of the cabin, a few wicker baskets, and a waterbottle of porous clay constitute their furniture. Still, the lot of the miner of the Sierra Morena is far superior to that of the miner of Almaden, who, poisoned by the noxious vapours of mercury, quickly succumbs, ere he has gained the prime of manhood. In South America the mining operations of the inhabitants somewhat resemble those of their Spanish ancestors, their habits and customs being imitated by the Indians, who have, however, to perform the harder part of the work. While Mexico and Peru were under the mother country, the Mita or law of compulsion existed, the Indians being forced to toil against their will in the mines, but since the emancipation of the colonies and the abolition of that nefarious law, they have returned to their agricultural pursuits, and are only occasionally found of their own free will labouring in the mines. Various modes are adopted for descending the mines. In some merely a single rope or chain with a loop at the end in which the miner places his foot is used, even when the depth is several hundred feet; in other mines baskets or tubs in which three or four men can stand are employed. While one of these is hauled up, another descends, and often fearful accidents have occurred by the tubs striking against each other, when their occupants have been thrown out. Occasionally the ropes and chains have given way, and the hapless miners have been dashed to pieces.
