As the several peoples inhabiting the earth have progressed from barbarism through the different stages of civilization, the transportation occasioned by their wants and desires has kept a close pace. By a study of the transportation—travel, movement of goods and commodities—and the means and facilities for its accomplishment, the relative civilization of any people, their rank and position may be accurately surveyed, graduated, and estimated. The highways of a nation, whether they be of the land or sea, or both, are most vital elements in its progress and could almost as well as transportation be considered the measuring rod of civilization.

Stages in Civilization.

—Sociologists differ as to what constitute the several stages of civilization. One might trace the development of man through literature, another through art, another through government; others consider his economic activities the more fundamental factors. The most widely used economic classification, according to Ely,[1] is based upon the increasing power of man over nature and consists of (1) Direct Appropriation, (2) The Pastoral Stage, (3) The Agricultural Stage, (4) The Handicraft Stage, and (5) The Industrial Stage. These stages are well illustrated in English history. The stage of direct appropriation corresponding to the prehistoric period and up to 54 B.C., when the Romans overran the island of Britain; the Pastoral stage from this time to the invasion by William the Conqueror, 1066; the Agricultural up to about the discovery of America, when a great impetus was given to travel and discovery; the stage of Handicraft, from 1500 to the invention of the steam engine and its application to manufacture at the beginning of the eighteenth century; the Industrial stage, to the present time. While these stages necessarily overlap each other considerably, it will be seen that as one declines the next is ushered in with some radical change in government or in economic or industrial condition. The present day—immediately following as it does the Great World War, out of which have issued many scientific discoveries and inventions, notably those advancing the theory and practice of air navigation, with many potential possibilities in new lines of transportation; and the setting forth of an idea which is capable of leading to a better understanding or even a confederation of nations and altering all forms of national government—may be the beginning of a new stage of civilization.

Stage of Direct Appropriation.

—This stage covers the whole course of prehistoric man from the time the first ape stood erect some 500,000 years ago[2] through the stone, bronze, and iron ages to the age of literature and art. During these long years civilization traveled far, for the least cultured savages observed have advanced not only away beyond the highest of the lower animals but also beyond the lowest intellectual estate of which human beings may be supposed capable of subsisting. And from the lowest to the highest of these tribes are shown traits varying as greatly in degree as from one stage in the above classification to another. The Indians at the time of the discovery of America and the three centuries following, and many of the tribes of Africa during the explorations of Livingstone and Stanley, were and still are in this stage and hence have been subjected to scientific study and investigation. Their governments while variable are of the primitive types. Ordinarily a chief autocratically rules because of hereditary influence. Little is manufactured, planting is scarcely known; by hunting, fishing, and collecting nature’s products of wild seeds and roots is a subsistence obtained often with long, arduous, and dangerous labor. Efficiency, as we understand that term to-day, is very low, and the number of persons that a given area can support is few. No one can predict but what to-morrow he may have to go hungry or suffer cold from the inclemency of the weather, for his store of food is nil or small, his shelter rudimentary and clothing scanty. Note the hardships of the party of Henry M. Stanley during his expedition across the African wilderness in quest of Emin Pasha.[3] Notwithstanding Stanley’s men were possessed of firearms and edged tools and carried some provisions with them, and were traversing a country teeming with vegetable and animal life, many times they were on the verge of starvation. The number of the natives in these wildernesses are no doubt kept low because of the extreme difficulties of procuring the necessities of life.

The barbarian requires less, of course, than the civilized man; he is satisfied with mere subsistence. He is improvident and relies upon picking up his needs from day to day as a robin picks worms from the grass. Cannibalism often exists, for the sacredness of human life has not yet been established, although magic and crude religious rites are seldom missing. While private personal property is recognized and retained by personal prowess, the ownership of land is absent. Coöperation of the crudest sort only is found; division of labor consists largely in having the females perform the work of planting, cultivating, carrying burdens—when these are attempted at all—cooking and caring for the children in the crudest fashion, leaving to the men the work of hunting, fishing, and fighting. Each tribe is self-sufficient and consists of a chief with a few followers bound together loosely for the purposes of protection from other tribes. Exchange, barter, and trade is at its lowest ebb; consequently transportation is practically unnecessary, and roadways except mere trails do not exist.

The Pastoral Stage.

—In the process of evolution certain animals undoubtedly were domesticated and used for food. Whether or not this domestication preceded or followed primitive agriculture or “hoe culture,” is not important, as the pastoral stage of culture evidently lies between the hunting and the farming stages. The written history of mankind indicates that this stage largely prevailed among the earlier Hebrew, Greek, and Teutonic races. A private ownership in cattle and herds was recognized, but the necessity of moving about with the flocks precluded fixed habitations, although large areas were claimed and held or endeavored to be held from trespass thereon by neighboring tribes. A given area would thus support a much larger number of people than in the preceding stage. A small amount of trading or bartering was carried on and consequently some transportation was required, but road building as such was little known. Rivers and coast waters for canoes and dugouts were no doubt early taken advantage of by the aborigines of bordering territories. But since there is so little division of labor, so little of barter and exchange, commerce was not developed much during this stage.

The Agricultural Stage.

—The growing and storage of crops, increased by the use of animal power, greatly changed the economic and social conditions of man. It made possible and profitable the living in fixed habitations, even in communities, and this brought out the needs of rules of government. But even yet each family provided without the assistance of others for practically all its own needs. In planting, reaping, threshing, grinding the meal and cooking, the family became the unit. No great division of labor was yet evident, consequently exchange, barter, and transportation still remained low. Ownership of land was necessary if a family was to cultivate the same land year after year. This meant definite rules and laws and consequently the development of governments. Ownership of herds and land brought wealth and a certain distinction in the community. Slavery, which had no doubt existed to some extent in the pastoral stage, here, because it greatly increased wealth, grew immensely. Large families likewise meant more workmen and greater wealth, distinction, and leisure, hence polygamy and polyandry often existed. As the evolution continued there was a trend toward handicraft and the division of labor; the products of one place began to be exchanged for the products of other places. This necessitated some forms of transportation, meager though they might be, and trails between communities.
