The variety of grain produced in the various countries depends largely upon the climate and the habits of the people. The predominant use of rice by the Asiatics, wheat by the Europeans, and maize by the aboriginal American, shows how people adapt themselves to the foods of prodigal growth. It also shows the effect different foods have upon the physical development of the various tribes that inhabit these remote countries. [Sidenote: Wheat]
