The conditions of the gift were that the court house was to be built of brick and to be at least forty feet square. In the following spring the town company donated fifty town lots, and the proceeds of these lots were to be used in the construction of the court house. In June, 1857, the court house was ordered built and it was to be two stories high, the first story to be of rock and the second story of wood. It was 24×18 feet square: however, the plans were subsequently changed, and, because of the gift of an additional fourteen lots by the town company, of a value of $6,000.00, a more pretentious building was erected in 1859, with a county jail adjoining it. Prior to the erection of the court house, there was a spirited contest between Mt. Pleasant, Monrovia, Lancaster and Sumner over the question of the county seat. In an election to determine the location, Atchison received a majority of 252 votes over all competitors for the county seat. The estimated total population of the county at the time was 2,745. In the next few years Atchison grew rapidly and the dreams of Senator Atchison and his associates bade fair to be realized on a large scale. The population of the town was about 500, and yet there were eight hardware stores, twelve dry goods stores, eight wholesale grocery stores, nineteen retail grocery stores, and twenty-six law firms. The banking business was controlled by the contracting firms of A. Majors & Company and Smoot, Russell & Company. The Atchison branch of the Kansas Valley Bank was the first in the State to be formed under the legislative act, authorized February 19, 1857, with a capital stock of $300,000.00. In the act, John H. Stringfellow, Joseph Plean and Samuel Dickson were named to open subscription books. An organization was effected in the spring of 1858, and the capital stock of the local organization was $52,000.00. The board of directors was composed of Samuel C. Pomeroy, president; W. H. Russell, L. R. Smoot, W. B. Waddell, F. G. Adams, Samuel Dickson and W. E. Gaylord. There was considerable rivalry between Sumner and Doniphan at the time, and shortly after the organization of the bank, a rumor, which was supposed to have started in Sumner, to the effect that the bank was about to suspend, caused the directors to publish a statement of its condition, showing that its assets were $36,638.00 and its liabilities $20,118.00. S. C. Pomeroy resigned as president before the year was out and was succeeded by William H. Russell. The bank subsequently had its name changed by the legislature to the Bank of the State of Kansas. Mr. Russell, the second president of the bank, made his home in Leavenworth and was an active pro-slavery man, being treasurer of the executive committee in 1856 to raise funds to make Kansas a slave State. This bank continued until 1866, when it went into voluntary liquidation and its stockholders wound up its affairs.
