Explanation:

Cattle trails were routes that were used during the 19th century in the American West. These were established before the Civil War in order to bring Texas cattle to market. They were particularly popular between the years of 1856 and 1896. Cattle drives were one of the main economic activities of the area, and the long distances covered and the need for rest led to the development of many towns along these routes.
