Schwellenbach issued an order of possession under the Second War Powers Act the following day, and the first tract was acquired on March 10. Some 4,218 tracts totaling were to be acquired, making it one of the largest land acquisition projects in American history. Most of the land (some 88 percent) was sagebrush, where eighteen to twenty thousand sheep grazed. About eleven percent was farmland, although not all was under cultivation. Farmers felt that they should be compensated for the value of the crops they had planted as well as for the land itself. Because construction plans had not yet been drawn up, and work on the site could not immediately commence, Groves decided to postpone the taking of the physical possession of properties under cultivation to allow farmers to harvest the crops they had already planted. This reduced the hardship on the farmers, and avoided the wasting of food at a time when the nation was facing food shortages and the federal government was urging citizens to plant victory gardens. The War Department arranged with Federal Prison Industries for crops to be harvested by prisoners from the McNeil Island Penitentiary. The harvest in the spring and summer of 1943 was exceptionally good, and high crop prices due to the war greatly increased land values. Litigation was needed to resolve disputes over the compensation due to the sellers. Discontent over the acquisition was apparent in letters sent from Hanford Site residents to the War and Justice Departments, and the Truman Committee began making inquiries. Stimson met with chairman of the committee, Senator Harry S. Truman, who agreed to remove the Hanford Site from the committee's investigations on the grounds of national security. Trial juries were sympathetic to the claims of the landowners and the payments awarded were well in excess of the government appraisals. When the Manhattan Project ended on December 31, 1946, there were still 237 tracts remaining to be settled. About 1,500 residents of Hanford, White Bluffs, and nearby settlements were relocated, as well as the Wanapum people, Confederated Tribes and Bands of the Yakima Nation, the Confederated Tribes of the Umatilla Indian Reservation, and the Nez Perce Tribe. Native Americans were accustomed to fishing in the Columbia River near White Bluffs for two or three weeks in October. The fish they caught were dried and provided food for the winter. The Natives rejected offers of an annual
