Bean-growing in a small way is fully warranted in every garden, but on a large scale it is a different question, being somewhat a matter of soil and location.
Food Value — The bean is one of the most excellent of human foods. Its botanical kinship is close to the pea, and both are legumes. The leguminous plants, it will be remembered, have the rare ability of obtaining nitrogen through the tubercles on their roots, taking this expensive element partly from the air, and not greatly impoverishing the soil by their growth.
Something of the food value of the bean may be learned by comparing its chemical analysis with that of beef. In 100 pounds of beans there are 23 pounds of protein (nitrogenous matter), while in 100 pounds of beef there are but about 15 to 20 pounds of protein. Peas are almost as rich as beans in protein, which is the tissue-building element of all foods, and, hence, it is easy to realize the fact that both beans and peas are foods of the highest economic value. They are standard foods of the world, entering into the diet of soldiers, laborers and persons needing physical strength.
It is generally safe to grow beans for the retail market of any town or centre of population, but to compete in the open wholesale market demands experience and good equipment on the part of the grower to insure profits.
