The assertion that unused land cannot be rented on reasonable terms is in the main unfounded, so far as it refers to land which is desired for agriculture. As a rule, any man who wishes to cultivate a portion of such land can fulfil his desire if he is willing to pay a rent that corresponds to its productiveness. After all, landowners are neither fools nor fanatics: while awaiting a higher price than is now obtainable for their land, they would prefer to get from it some revenue rather than none at all. As a matter of fact, almost all the agricultural land that is immediately available for renting, is constantly under cultivation. This refers to land that is already under the plough, and is provided with buildings and other necessary improvements. Practically none of this is out of use. New land which is without buildings is not wanted by tenants, unless it is convenient to their residences, because they do not desire to expend money for permanent improvements upon land that they do not own. True, the present owners of such land might erect buildings, and then let it to tenants. In so far as new land might profitably be improved and cultivated, and in so far as the owners are unwilling or unable to provide the improvements, the present system does keep out of use agricultural land that could be cultivated by tenants. Mineral and timber lands are sometimes withheld from tenants because the owners wish to limit the supply of the product, or because they fear that a long-term lease would prevent them from selling the land to the best advantage. As to urban sites, the contention that we are now examining is generally true. The practice of leasing land to persons who wish to build thereon does not, with the exception of a very few cities, obtain in the United States for other than very large business structures. As a rule, it does not apply to sites for residences. The man who wants a piece of urban land for a dwelling or for a moderately sized business building cannot obtain it except by purchase.
