ホームステッド法
To encourage settlement of western lands, Congress passed the first of several Homestead Acts in 1862, granting parcels in increments to homesteaders who could maintain a living on land for a period of time. Congress also made huge land grants to various railroads working to complete a transcontinental rail system. Much of the latter grants intentionally included mineral and timber-rich lands so that the railroads could get financing to build. Again, the hypothesis was that the railroads would sell off the land to get money.
