单选题 Governing bodies of the American colonies raised questions about land distribution and use soon after winning independence. A 1785 law provided for surveying the west, with the intention of opening up land for family farms. Areas between the Ohio and Mississippi rivers, for example, were allowed to become states on equal terms with the original thirteen as soon as their populations reached a certain level. The lands were to be sold at $ 2. 50 per hectare. Most of the settlers who braved the many dangers of western expansion did not have money to pay for land. Often they settled as occupiers of land without any clear title to their farms. After becoming established, these settlers campaigned to get the law changed so that some of the land was declared free, while other lands could be bought at a minimal price and paid for over a period of years. Successive laws culminated in the Homestead Act of 1862, giving free land to prospective settlers provided they agreed to farm the land or live on the land for a period of years. The strategy behind this and subsequent laws was to get land into the hands of family farmers. Land was also given to those who organized the railroads to encourage those costly ventures, and other lands were given to "land grant colleges," which were designed to educate farmers in the newest agricultural and scientific methods. In turn, these groups sometimes sold land to settlers at modest cost. All in all, the law-making did meet its objective of covering the new nation with family farms.
