The field bean is one of the great food crops of the world. Very few other edible seed crops produce more nutrition to the acre. Beans represent one of the world’s most concentrated food products, and consequently are in great demand in places where it is difficult to transport food. As a food stuff in mines, lumber camps, construction camps, on the frontier, and in the army and navy, beans are always popular because of their immense food value in comparison with their bulk, and normal cost. A bushel of beans has a food value equivalent to 108 pounds of round steak.
