2. In the South it is common for the landlord to require a definite number of pounds of cotton per acre or a certain number of bales of cotton for a one or two-mule farm, as the case may be. This is classified by the census authorities as "cash rent," but will here be called "crop rent." Crop rent is less common than either cash or share rent in the northern and western states, although perhaps the most common form in the South. Crop rent, however, is met with in some sections, as in western New York where certain large landowners require a definite number of bushels of wheat, oats or maize and make certain stipulations as to hay and straw. They charge a cash rent for pasture. 3. Much the most common form of tenancy, however, is that where a certain percentage or share of the product is given the landlord for the use of the land. Before entering into a discussion of the customary conditions under which land is rented on shares it may be helpful to point out the fundamental differences between cash rent, crop rent and share rent. In case of cash rent, the landlord takes no risk, either as to the price or the amount of product. In the case of crop rent, he shares the risk as to the variation in price, but not as to the amount of crop raised. The latter may depend upon the clemency of the weather or upon the industry and skill of the tenant. In the case of share rent, both landlord and tenant share equally as to variation in the price and the amount of product. Three forms of share rent may be recognized: (a) Where landlord furnishes only real estate (land and buildings), the tenant supplying everything else, including teams, machinery, labor, seeds and fertilizers. Under these conditions it is customary for the landlord to receive one-third and the tenant two-thirds of the crop raised or the product produced.
