"The Aztecs were thus enabled to give a brilliant coloring to their webs of cotton, which staple, in the warmer regions of their country, they raised in abundance. With their cotton fabrics, manufactured of every degree of fineness, they had the original art of interweaving the delicate hair of rabbits and other animals, which made a cloth of great warmth as well as beauty. "On this they often laid a rich embroidery of birds, flowers, or some other fanciful device. It is supposed that the Aztec 'silk,' mentioned by Cortez, was nothing more than this fine texture of cotton, hair, and down. "But the art in which they especially excelled was their plumage or feather-work. Some few existing specimens of this ancient art (one of them a vestment said to have been worn by Montezuma himself) have, we are told, 'all the charm of Florentine mosaic.' "The gorgeous plumage of tropical birds, especially of the parrot-tribe, afforded every variety of color, and the fine and abundant down of the humming-bird supplied them with a finish of soft aerial tints. The feathers pasted on a fine cotton web were wrought into dresses for the wealthy. Hangings for apartments and ornaments for the temples were thus fashioned. Labor was held in honorable estimation among this people. An aged Aztec chief thus addressed his son: 'Apply thyself to agriculture, or to feather-work, or some other honorable calling. Thus did your ancestors before you. Else, how could they have provided for themselves and their families? Never was it heard that nobility alone was able to maintain its possessor.' "The occupation of the merchant was held by them in high respect. These were of prime consideration in the body politic, and enjoyed many of the most essential advantages of an hereditary aristocracy. Mexico, as their abundant use among the Aztecs testifies, is especially rich in precious stones. It is the land of the emerald, the amethyst, the turquoise, and the topaz; and that superbest of gems, the fire opal, is native to its generous soil. "One of Cortez's wedding gifts to his second bride is thus described: 'This was five emeralds of wonderful size and brilliancy. These jewels had been cut by the Aztecs into the shapes of flowers, and fishes, and into other fanciful forms, with an exquisite style of workmanship which enhanced their original value.' "It was gossiped at court that the Queen of Charles the Fifth had an eye to these magnificent gems, and that the preference given by Cortez to his fair bride had an unfavorable influence on the Conqueror's future fortunes. Among the 'royal fifth' of the Mexican spoils sent by Cortez to the Spanish Emperor, we are told of a still more wonderful emerald. It was cut in a pyramidal shape, and of so extraordinary a size that the base of it was affirmed to have been as broad as the palm of the hand.
