The Two-rowed Barley's spike, or ear, is long and somewhat compressed, and the grain is of a very good quality. It is sown in the spring. Barley succeeds best in soils of medium consistency, but accommodates itself to almost every variety of soil, except very moist ones. It endures a drought better than excessive moistures, but it requires as deep and good tillage as wheat.

Indian Corn, or maize, grows with a strong, jointed stalk, rising to the height of five to fifteen feet. The male or sterile flowers are arranged in a loose, spreading panicle at the apex, called the tassel and the female fertile flowers on the side. Each plant bears from one to five ears which are are cylindrical and enclosed in a covering of leaves called husks. The ears consists of grain, arranged around a pithy cylinder, called the cob. The seeds are rounded on the surface and compressed on the sides. Indian Corn is annual and is one of the most important of all the cultvated plants.
