The discovery of the grain of wheat in the remains of the lake dwellers tells us some things about men’s travels even in those early days, for wheat is not a wild plant there and must have come to central Europe from a great distance. Researches upon the home and antiquity of wheat are not very definite, but its occurrence as a wild plant somewhere in Mesopotamia or the vicinity appears to be indicated. The Chinese grew it 2700 B.C. and the earliest Egyptians spoke of its origin with them as due to mythical personages such as Isis, Ceres, or Triptolemus. From its ancient and perhaps rather restricted home it has gone throughout the temperate parts of the earth and now forms perhaps the most important source of food. Although many different kinds of wheat are raised in different parts of the world most of them have been derived from one wild ancestor, _Triticum sativum_. Forms known as hard and soft wheat and dozens of others suited to different regions or market conditions have been developed by plant breeders. As the most important of all the cereals it has been much studied, and its cultivation in America is on such a tremendous scale that we furnish a large part of the world’s supply. Russia, Argentina, and the southern part of Australia also raise large quantities. The plant is a grass and the “seed” is really a grain or fruit in which the outer husk tightly incloses the true seed. It were perhaps well to note here that popular stories about the germination of grains of wheat taken from Egyptian mummies are not true. Wheat and even corn are sometimes given to travelers, and it is taken from these ancient Egyptian tombs. But it was not put there by the early Egyptians, as the presence of corn proves only too well. For this cereal is an American plant unknown before Columbus and 1492. Arabs and others have recently inserted various seeds in these mummies, some of which undoubtedly have germinated--hence the fable. The early Egyptians did put seeds in their mummy cases, but none have ever germinated. INDIAN CORN OR MAIZE
