One day, when the young princess was sleeping in her little arbor, the ever watchful nurse observed a viper among the flowers, which she had strown about her pillow, just ready to dart its venomous fang into the bosom of her darling. Quick as lightning she seized the reptile in her hand, and, before he had time to turn upon her, flung him upon the floor, and crushed him under her sandalled heel. Passionately embracing her dear charge, she hastened with her to the apartments of the queen, and related the story of her narrow escape, with so much of the eloquence of gratitude for being the favored instrument of her deliverance from so cruel a death, that it deeply affected the heart of the queen. She embraced her child and Karee, as if both were, for the moment, equally dear to her; and then, in return for the faithful service, rendered at the hazard of her own life, she promised to bestow upon the slave whatever she chose to ask. "Give me, O give me freedom, and a chinampa, and I ask no more," was the eager reply of Karee to this unexpected offer of the queen. The request was immediately granted; and the first sorrow that ever clouded the heart of the lovely Tecuichpo, was that of parting with her faithful and loving Karee. A _chinampa_ was a floating island in the lake of Tezcuco, upon whose very bosom the imperial city was built. They were very numerous, and some of them were large, and extremely beautiful. They were formed by the alluvial deposit in the waters of the lake, and by occasional masses of earth detached from the shores, held together by the fibrous roots, with which they were penetrated, and which in that luxurious clime, put out their feelers in every direction, and gathered to their embrace whatever of nutriment and support the richly impregnated waters afforded. In the process of a few years accumulation, the floating mass increased in length, breadth and thickness, till it became an island, capable of sustaining not only shrubs and trees, but sometimes a human habitation. Some of these were from two to three hundred feet square, and could be moved about at pleasure, like a raft, from city to city, along the borders of the lake. The natives, who were skilful gardeners, and passionately devoted to the cultivation of flowers, improved upon this beautiful hint of nature, to enlarge their means of supplying the capital with fruits, vegetables and flowers. Constructing small rafts of reeds, anchoring them out in the lake, and then covering them with the sediment drawn up from the bottom, they soon found them covered with a thrifty vegetation, and a vigorous soil, from which they were able to produce a large supply of the various luxuries of their highly favored clime.
