At last Stephenson's party of miners arrived from England, but they gave him even more trouble than the peons had done. They were rough, drunken, and sometimes ungovernable. He set them to work at the Santa Anna mine without delay, and at the same time took up his abode among them, "to keep them," he said, "if possible, from indulging in the detestable vice of drunkenness, which, if not put a stop to, will eventually destroy themselves, and involve the mining association in ruin." To add to his troubles, the captain of the miners displayed a very hostile and insubordinate spirit, quarreled and fought with the men, and was insolent to the engineer himself. The captain and his gang, being Cornishmen, told Robert to his face that because he was a North-country man, and not brought up in Cornwall, it was impossible that he should know any thing of mining. Disease also fell upon him--first fever, and then visceral derangement, followed by a return of his "old complaint, a feeling of oppression in the breast." No wonder that in the midst of these troubles he should longingly speak of returning to his native land. But he stuck to his post and his duty, kept up his courage, and by a mixture of mildness and firmness, and the display of great coolness and judgment, he contrived to keep the men to their work, and gradually to carry forward the enterprise which he had undertaken. By the beginning of July, 1826, quietness and order had been restored, and the works were proceeding more satisfactorily, though the yield of silver was not as yet very promising, the engineer being of opinion that at least three years' diligent and costly operations would be necessary to render the mines productive. In the mean time he removed to the dwelling which had been erected for his accommodation at Santa Anna. It was a structure speedily raised after the fashion of the country. The walls were of split and flattened bamboo, tied together with the long fibres of a dried climbing plant; the roof was of palm-leaves, and the ceiling of reeds. When an earthquake shook the district--for earthquakes were frequent--the inmates of such a fabric merely felt as if shaken in a basket, without sustaining any harm. In front of the cottage lay a woody ravine, extending almost to the base of the Andes, gorgeously clothed in primeval vegetation--magnolias, palms, bamboos, tree-ferns, acacias, cedars; and towering over all were the great almendrons, with their smooth, silvery stems, bearing aloft noble clusters of pure white blossom. The forest was haunted by myriads of gay insects, butterflies with wings of dazzling lustre, birds of brilliant plumage, humming-birds, golden orioles, toucans, and a host of solitary warblers. But the glorious sunsets seen from his cottage-porch more than all astonished and delighted the young engineer, and he was accustomed to say that, after having witnessed them, he was reluctant to accuse the ancient Peruvians of idolatry.
