The first large-scale effort to drive cattle from Texas to the nearest railhead for shipment to Chicago occurred in 1866, when many Texas ranchers banded together to drive their cattle to the closest point that railroad tracks reached, which at that time was in Sedalia, Missouri. However, farmers in eastern Kansas, afraid that Longhorns would transmit cattle fever to local animals as well as trample crops, formed groups that threatened to beat or shoot cattlemen found on their lands. Therefore, the 1866 drive failed to reach the railroad, and the cattle herds were sold for low prices. However, in 1867, a cattle shipping facility was built west of farm country around the railhead at Abilene, Kansas, and became a center of cattle shipping, loading over 36,000 head of cattle that year. The route from Texas to Abilene became known as the Chisholm Trail, after Jesse Chisholm, who marked out the route. It ran through present-day Oklahoma, which then was Indian Territory. Later, other trails forked off to different railheads, including those at Dodge City and Wichita, Kansas. By 1877, the largest of the cattle-shipping boom towns, Dodge City, Kansas, shipped out 500,000 head of cattle.
