line and meridian) at the southeast corner of the Temple Block, and from there extended that survey over 2 million acres. Because of numerous conflicts between the surveyor and the territorial government the first surveyor general abandoned his post in 1857. His successors recommended that no additional land be surveyed. Conflict between the federal and territorial governments kept the issue on hold until 1868, and in the meantime, large sections of the territory were transferred to neighboring territories and states. Again in 1868, Congress directed the President to appoint a surveyor general in the Utah Territory, to establish a land office in Salt Lake City, and to extend the federal land laws over the same. The land office opened 9 March 1869. In 1857, when the Mormon practice of polygamy came to national awareness, President James Buchanan responded to public outcry by sending an army of 2500 soldiers, called the Utah Expedition, to investigate the LDS Church and install a non-LDS governor to replace Brigham Young. In response, Brigham Young imposed martial law, sending the Utah militia to harass the soldiers, a conflict called the Utah War. Young eventually surrendered to federal control when the new territorial governor, Alfred Cumming, arrived in Salt Lake City on April 12, 1858. Most troops pulled out at the beginning of the American Civil War. In order to secure the road to California during the Civil War, more troops arrived under the command of Colonel Patrick Edward Connor in 1862. They settled in the Fort Douglas area east of the city. Thoroughly anti-LDS, Connor viewed the people with disdain, calling them, "a community of traitors, murderers, fanatics, and whores." To dilute their influence he worked with non-LDS business and bank owners, and also encouraged mining. In 1863 some of his troops discovered rich veins of gold and silver in the Wasatch Mountains. In 1863, Brigham Young preached at the Tabernacle that intermarriage between Blacks and Whites was forbidden on penalty of death and declared himself opposed to the abolition of slavery. In 1866, Thomas Coleman, a Black Mormon man, was murdered, and his body was left on Capitol Hill with an anti-miscegenation warning attached to his body. In 1883, Sam Joe Harvey, another Black man, was lynched for allegedly shooting a police officer, and his body was dragged down State Street. In 1868 Brigham Young founded the Zion's Co-operative Mercantile Institution (ZCMI) as a
