Cattle drives were a major economic activity in the 19th and early 20th century American West, particularly between 1850s and 1910s. In this period, 27 million cattle were driven from Texas to railheads in Kansas, for shipment to stockyards in St. Louis and points east, and direct to Chicago. The long distances covered, the need for periodic rests by riders and animals, and the establishment of railheads led to the development of "cow towns" across the frontier.

The pivotal position of the Indian war narratives and John Filson's legend of Boone's "baptism by combat" in the development of American mythology and literature is explained by their applicability to the universal problem of the colonial period: the problem of acculturation, of adjusting the mores and world view of one's native culture to the requirements of life in an alien environment.

Because of the nature of myth and the myth-making process, it is a significant comment on our characteristic attitudes toward ourselves, our culture, our racial subgroupings, and our land that tales of strife between native Americans and interlopers, between dark races and light, became the basis of our mythology and that the Indian fighter and hunter emerged as the first of our national heroes. In order to understand the complex and many-leveled influence of our history on our mythology, and of mythology on our culture, we must understand the nature of the peculiar forces that shaped mythology in America.

From the conditions of frontier life came intellectual traits of profound importance. The works of travelers along each frontier from colonial days onward describe certain common traits, and these traits have, while softening down, still persisted as survivals in the place of their origin, even when a higher social organization succeeded. The result is that, to the frontier, the American intellect owes its striking characteristics. That coarseness and strength combined with acuteness and inquisitiveness, that practical, inventive turn of mind, quick to find expedients, that masterful grasp of material things, lacking in the artistic but powerful to effect great ends, that restless, nervous energy, that dominant individualism, working for good and for evil, and withal that buoyancy and exuberance which comes with freedom -- these are traits of the frontier, or traits called out elsewhere because of the existence of the frontier.

As the eastern lands were taken up, migration flowed across them to the west. Daniel Boone, the great backwoodsman, who combined the occupations of hunter, trader, cattle-raiser, farmer, and surveyor -- learning, probably from the traders, of the fertility of the lands of the upper Yadkin, where the traders were wont to rest as they took their way to the Indians, left his Pennsylvania home with his father, and passed down the Great Valley road to that stream.

Learning from a trader whose posts were on the Red River in Kentucky of its game and rich pastures, he pioneered the way for the farmers to that region. Thence he passed to the frontier of Missouri, where his settlement was long a landmark on the frontier. Here again he helped to open the way for civilization, finding salt licks, and trails, and land.

The effect of the Indian frontier as a consolidating agent in our history is important. From the close of the seventeenth century various intercolonial congresses have been called to treat with Indians and establish common measures of defense. Particularism was strongest in colonies with no Indian frontier. This frontier stretched along the western border like a cord of union. The Indian was a common danger, demanding united action. Most celebrated of these conferences was the Albany congress of 1754, called to treat with the Six Nations, and to consider plans of union. Even a cursory reading of the plan proposed by the congress reveals the importance of the frontier. The powers of the general council and the officers were, chiefly, the determination of peace and war with the Indians, the regulation of Indian trade, the purchase of Indian lands, and the creation and government of new settlements as a security against the Indians.

Long before the pioneer farmer appeared on the scene, primitive Indian life had passed away. The farmers met Indians armed with guns. The trading frontier, while steadily undermining Indian power by making the tribes ultimately dependent on the whites, yet, through its sale of guns, gave to the Indian increased power of resistance to the farming frontier. French colonization was dominated by its trading frontier; English colonization by its farming frontier. There was an antagonism between the two frontiers as between the two nations. Said Duquesne to the Iroquois,

Little by little he transforms the wilderness, but the outcome is not the old Europe, not simply the development of Germanic germs, anymore than the first phenomenon was a case of reversion to the Germanic mark. The fact is, that here is a new product that is American.

Now, the frontier is the line of most rapid and effective Americanization. The wilderness masters the colonist. It finds him a European in dress, industries, tools, modes of travel, and thought. It takes him from the railroad car and puts him in the birch canoe. It strips off the garments of civilization and arrays him in the hunting shirt and the moccasin. It puts him in the log cabin of the Cherokee and Iroquois and runs an Indian palisade around him. Before long he has gone to planting Indian corn and plowing with a sharp stick; he shouts the war cry and takes the scalp in orthodox Indian fashion. In short, at the frontier the environment is at first too strong for the man. He must accept the conditions which it furnishes or perish, and so he fits himself into the Indian clearings and follows the Indian trails.
