As a rule, when the farm has been acquired by a son, the latter has operated the farm as tenant or partner for a period previous to his ownership and during lifetime of the father. In some instances the son has boarded with the parents or the parents with the son and his wife; or, in the case of a daughter, with the daughter and son-in-law. Where there are several heirs, as is apt to be the case, the son operating the farm is required to purchase or rent the interest of the other heirs, unless the farm is large enough to be divided, which is less seldom the case than is popularly supposed. Thus, if there are 200 acres of land worth $50 an acre, and five heirs, the young farmer may inherit $2,000, and be required to assume the remaining $8,000 as an obligation. He may borrow this money at the bank, placing a mortgage upon the farm, thus settling with the other heirs at once. Or he may pay the other heirs rent on their share of the farm. In any case he will, if successful, gradually cancel his obligation and become owner of the farm. That no heir is willing to assume this responsibility is the most common reason for a farm changing from one family to another, and the disruption of community interests. The customary, or normal, method of acquiring land has been and still is a combination of tenancy, inheritance and mortgage. Without some tenant system and without the farm mortgage, it would be impossible for the average young man to acquire a farm. That men are constantly advancing from farm tenant to landowner is shown by statistics giving the percentage of tenants by ages. The majority of farmers under 30 are renters. Most farmers over 45 are owners of farm land. Thus in Illinois, in 1900, approximately 75% of the farmers under 25 years of age rented their farms, while less than 20% of the farmers over 55 years of age were tenants. The question for the young man to consider is not what effect the tenant system has upon the welfare of the nation or what political ills may be connected with farm mortgages, but how to make use of these necessary and beneficent agencies for the acquirement of a farm. A system of tenancy which leads to absent landlordism and a permanent tenant class is thoroughly vicious, while a practice which enables a man to become, within a reasonable period, a land-owning farmer is a thoroughly approvable and, indeed, necessary method of acquiring land.
