Adjoining the principal edifice were others, devoted to various objects. One was an armory, filled with the weapons and military dresses worn by the Aztecs, all kept in the most perfect order, ready for instant use. The emperor was himself very expert in the management of the _maquahuitl_, or Indian sword, and took great delight in witnessing athletic exercises and the mimic representation of war by his young nobility. Another building was used as a granary, and others as warehouses for the different articles of food and apparel contributed by the districts charged with the maintenance of the royal household. There were, also, edifices appropriated to objects of quite another kind. One of these was an immense aviary, in which birds of splendid plumage were assembled from all parts of the empire. Here was the scarlet cardinal, the golden pheasant, the endless parrot-tribe with their rainbow hues (the royal green predominant), and that miniature miracle of nature, the humming-bird, which delights to revel among the honeysuckle bowers of Mexico.[331] Three hundred attendants had charge of this aviary, who made themselves acquainted with the appropriate food of its inmates, oftentimes procured at great cost, and in the moulting season were careful to collect the beautiful plumage, which, with its many-colored tints, furnished the materials for the Aztec painter. A separate building was reserved for the fierce birds of prey; the voracious vulture-tribes and eagles of enormous size, whose home was in the snowy solitudes of the Andes. No less than five hundred turkeys,{*} the cheapest meat in Mexico, were allowed for the daily consumption of these tyrants of the feathered race. {*} [The turkey was introduced to Europe from Mexico, as has before been stated.--M.]
