"There are men now living in Missouri and Illinois who drove cattle from that vast breeding ground west of the Mississippi river, into central Illinois, for the cattle kings, Jacob Strawn and John T. Alexander. These herds, numbering about 300 to 400 head, grazed leisurely across the open country at about 15 miles or so a day. During the war, the trade was more or less interrupted, but the practice was continued until settlement and railroads rendered trailing both unnecessary and impossible. "The annexation of Texas to the United States, and the discovery of gold in California in 1849, resulted in an influx of population and capital that soon exerted a stimulating effect upon the production of cattle throughout the southwest, as well as beyond the Sierra Nevada Mountains in the west. "At a comparatively early date, there was a ready market for Illinois bred cattle to go to the states west of the Mississippi river to be used for breeding stock. The development of the range cattle industry created a strong demand for pure bred bulls, and cattle breeders of Illinois were called upon, perhaps to a greater extent than those of any other state in the Union, to supply this demand. The range cattle business also created a market for young cows and heifers to be used for breeding purposes. This demand steadily increased from year to year, until a very large part of the yearly product of pure bred cattle in Illinois was absorbed for that purpose."[21] "In 1880, the range cattle trade was yet in a transition stage, especially as to the destination of marketable cattle and the special use to which they were put. Before this time, the bulk of the range cattle trade was divided between the coming establishments of the west, slaughter for home consumption, for exportation as dressed carcasses to the eastern markets, and shipping on the hoof to eastern states as feeders. Large feeding stables had been established in Nebraska for the purpose of feeding out these large numbers of rangers, but they could not utilize all of them. The overflow of these grass fat rangers found their way to eastern feed lots to be finished on the grain of the corn belt. The numbers increased from year to year, and extended farther and father east as the numbers increased. "The fact that one of the large feeding plants of Nebraska could turn off as many as 2000 ripe range steers in one month, gives some indication of the immense capacity of the range cattle trade. "As the Indians were confined more closely from year to year, there were more grazing lands opened up to be devoted to the raising of these range cattle. Most people at this time, seeing the rapid increase of the range industry, thought there would never be a beef famine as the economists of the time predicted. They said such economists always look on the dark side of things."[22]
