The year of 1859 was a big year in the history of Atchison, for in that year the percentage of the growth of the town was greater than any other year in its history. The fact that it was the best point on the Missouri river for the overland staging and freighting outfits, brought it in greater commercial prominence. At that time, Irwin & McGraw were prominent contractors, who were supplying the various military posts on the frontier. The mere fact that these Government trains were started from Atchison, gave the town wonderful prestige. It was nothing unusual to see two or three steamboats lying at the levee, discharging freight, and as many more in sight either going up the river from St. Louis, or down the river from St. Joe. It was not uncommon for a boat to be loaded at Pittsburgh, Pa., or Cincinnati, Ohio, going down the Ohio river and up the Mississippi and Missouri to Atchison; it was not an unusual sight to see a whole boat load of wagons and ox yokes, mining machinery, boilers and other material necessary for the immense trade of the West. The greater part of the traffic out of Atchison to the West was over the Military road, along the south bank of the Platte, and along this road teams of six to eight yoke of cattle, hauling heavily loaded wagons, and strings of four or six horse or mule teams, formed almost an endless procession. The liveliest period of overland trade extended from 1859 to 1866, during which time there was on the plains and in the mountains an estimated floating population of 250,000. The greater majority of the people on the plains produced but few of the necessities of life, and consequently they had to be supplied from the Missouri river. During the closing year of the Civil war, the travel was immense, most of the emigration going into the gold mining camps of the Northwest.
