Mary had made up her mind that they should not have been taken thither if there were any real danger; and so, though she could have preferred her mule taking the inner side of the ledge, and was not too happy when it climbed like a cat, she smiled, and answered all inquiries that she did not think she ought to be frightened. The region was in general more stern than beautiful, the clefts between the hills looking so deep, that it seemed as if an overthrown mountain could hardly fill them; but now and then came sudden peeps of that wonderful ocean; or almost under her feet, as if she could throw a stone into it, there would lie an intensely green valley, shut in with feathering pines, and the hacienda and grazing llamas dwindled, so that they could have been taken for a Swiss farm and flocks of sheep. Not till the middle of the day did they meet the line of mules, and not until the sunset did they find themselves close before the wonderful perforated San Benito summit. It was, unlike many other metalliferous hills, an isolated, sharply-defined mass of rock, breaking into sudden pinnacles and points, traversed with veins of silver. These veins had been worked with galleries, which, even before the Spanish conquest, had honeycombed the solid rock, and had been thought to have exhausted its riches; but it had been part of Oliver Dynevor's bold speculations to bring modern science to profit by the leavings of the Peruvians and their destroyers. It was a marvellous work, but it might still be a question whether the profit would bear out the expense. However, that was not the present consideration. No one could feel anything but admiring astonishment at the fantastic craggy height of peaks and spires, rising against the darkening sky, like the very stronghold of the Giant of the Western Star; and, with the black openings of the galleries, here and there showing the lights of the workmen within. Mary remembered the tales, in which Louis used vainly to try to interest her, of metal-working Dwarfs within the mountains; and would have been glad to tell him that, after all, reality was quite as strange as his legends. The miners, Indians and negroes, might truly have been Trolls, as, with their brown and black countenances, and wild bright attire, they came thronging out of their rude houses, built of piled stones on every tolerably level spot. Three or four stout, hearty Cornish miners, with picks on their shoulders, made the contrast stranger; and among them stood a young man, whose ruddy open face carried Mary home to Ormersfield in one moment; and she could not but blush almost as if it had been Louis, when she bent her head in acknowledgment of his bow.
