At a sound so hostile, Befo bristled and uttered a low bark, as if to apprize his master of the presence of danger; but Juan knew enough of the habits of the Mexican kings to understand that their gardens, besides enclosing all that was beautiful among plants, contained also aviaries and menageries, in which were collected the birds and beasts of their empire;--in other words, they were Zoological Gardens, such as the advance of science is now establishing in the countries of Europe. A little fawn, feeding hard by, started with more terror at this unusual cry of Befo, than at any of the howls to which it had been long accustomed, and ran timidly away. As it fled, Juan remarked that its neck was encircled by a chaplet of flowers, as if lately put on by some caressing hand. At this sight a new impulse seemed to seize the youth. He faltered, hesitated, cast his eye to the wall, on which Techeechee was yet standing, and then marking the quarter whither the little animal had fled, he beckoned to Befo to take post at his heels, and immediately followed. He soon found himself among a maze of copses, among which were scattered divers cages or baskets, of great strength, secured to the trunks of trees, and little paddocks equally strong, each containing some ferocious or untameable beast, many of them brought from the most distant provinces. Thus he beheld,--besides an abundant display of pumas or mitzlis, (the maneless lion,) jaguars, wolves, ounces, and wild dogs,--the bison of Chihuahua staggering in his pen, the antelope or prong-horn of the north, and even the great bear from the ridges of the Oregon or Rocky Mountains. The tapir of Guatemala rolled by his fenny pool, and the peccary herded hard by. Here were apes, ant-eaters, porcupines, and a thousand other animals; and among them, imprisoned with the same jealous care, in suitable cages, were the reptiles of the country,--lizards and adders, and all the family of the Crotalus, from the common rattlesnake of America to that frightful one of Mexico and South America, which has been distinguished as especially the Horrid. Here was the phosphorescent _cencoatl_, whose path through the bushes and grass by night is said to be indicated by the gleaming light of his body; the _tlilcoa_, or great black serpent of the mountains, and the still more formidable and gigantic _canauhcoatl_, or Boa-Constrictor, which, like his neighbour, the cayman or crocodile, from the same boiling fens of the coast, made his prey upon the largest stags, and even human beings. With these were many smaller snakes, distinguished for their beauty, and sometimes their docility, some of which latter, entirely harmless, were allowed to crawl about at liberty.
