“ From 1867 to 1871 about 10,000 cars of live stock were shipped out of Abilene, and in 1872 about 80,000 head of cattle were shipped from Wichita. “The settlement of the valleys of the Arkansas and the Ninnescah rivers rendered it impractical to reach Wichita shipping yards after 1873, and the loading of cattle was transferred to points on the railroad farther west, halting finally at Dodge City, where 1887 saw the end of the use of the famous Abilene cattle trail.” ”
