Abbe Clavigero, in his History of Mexico, says, that when the Mexicans were brought under subjection to the Colhuan and Tapanecan nations, and confined to the miserable little islands on the Lake of Mexico, they had no land to cultivate, until necessity compelled them to form moveable fields and gardens, which floated on the waters of the lake. The method which they adopted to make these, and which they still practise, is extremely simple. They plat and twist together willows and roots of marsh plants, or other materials, which are light, but capable of supporting the earth firmly united. Upon this foundation they lay the hight bushes which float on the lake; and over all, the mud and dirt which they draw up from the bottom. Their regular figure is quadrangular; their length and breadth various; but generally they are about eight perches long, and not more than three in breadth, and have less than a foot of elevation above the surface of the water. These were the first fields which the Mexicans had after the foundation of Mexico; there they first cultivated maize, pepper, and other plants. In time, as these fields became numerous from the industry of the people, they cultivated gardens of flowers and odoriferous plants, which they employed in the worship of their gods, and for the recreation of their nobles. At present they cultivate flowers, and every sort of garden herbs, upon them. Every day at sunrise, innumerable vessels loaded with various kinds of flowers and herbs, cultivated in those gardens, arrive by the canals, at the great market-place of that capital. All plants thrive in them surprisingly; the mud of the lake affords a very fertile soil, and requires no water from the clouds. In the large gardens there is commonly a little tree, and even a little hut] to shelter the cultivator, and defend him from rain or the sun. When the chinampa, or owner of a garden, wishes to change his situation, to remove from a disagreeable neighbour, or to come nearer to his own family, he gets into his little vessel, and by his own strength alone, if the garden is small, he tows it after him, and conducts it wherever he pleases. That part of the lake, where these floating gardens are, is a place of high recreation, where the senses receive all possible gratification.
