children were regarded as belonging to the mother's family. The Mixtec ceremony was more like that of the Aztec, but besides the tying together of the garments of the couple, it included also the cutting of part of their hair. Polygamy was also practised in this region.
Much of the time of the more settled peoples of Mexico was devoted to agriculture, and even a few of the Chichimec tribes, who had absorbed something of the culture of their more advanced neighbours, reared a little maize which was tended by serfs. 'The Otomi also practised agriculture to some extent. Maize was the most important product of cultivation, and the respect in which it was held is seen in the superstition that if a man saw maize-grains lying on the ground and failed to pick them up, they would cry to the gods for vengeance upon him. Circumstances, chief of which must be reckoned the restriction of territory when they first became settled, led to the development of intensive cultivation among the Aztec, and the invention of the celebrated "floating gardens." These were osier rafts, piled with earth and lake mud, which, so it is said, moved about the surface of the lake until they were finally anchored by the roots of the trees which sprang up on their surface.
