Texas where the cattle grazed during the year, but Texas cattlemen almost immediately instituted the annual practice of driving that portion of their herds that was ready for market overland to Abilene in the spring. There they met representatives of Eastern packinghouses, to whom they sold their cattle. The open-range cattle industry prospered beyond expectations and even attracted capital from conservative investors in the British Isles.

In the meantime, a new menace had appeared in the form of the advancing frontier of population; but the construction of the Santa Fe Railway through Dodge City, Kan., to La Junta, Colo., permitted the cattlemen to move their operations westward ahead of the settlers; Dodge City replaced Abilene as the principal centre for the annual meeting of cattlemen and buyers. Despite sporadic conflicts with settlers encroaching upon the high plains, the open range survived until a series of savage blizzards struck the plains with unprecedented fury in the winter of 1886-87, killing hundreds of thousands of cattle and forcing many owners into bankruptcy. Those who still had some cattle and some capital abandoned the open range, gained title to lands farther west, where they could provide shelter for their livestock, and revived a cattle industry on land that would be immune to further advances of the frontier of settlement. Their removal to these new lands had been made possible in part by the construction of other railroads connecting the region with Chicago and the Pacific coast.The expansion of the railroadsIn 1862 Congress authorized the construction of two railroads that together would provide the first railroad link between the Mississippi valley and the Pacific coast. One was the Union Pacific, to run westward from Council Bluffs, Iowa; the other was the Central Pacific, to run eastward from Sacramento, Calif. To encourag...
