1. Transportation of goods and men is one of the most important modes of production. When utility was thought of as inherent in things rather than as resulting from a relation between things and wants, it was usual to consider only those industries as truly productive that brought something physical into existence, as do agriculture and the extractive industries. Even after it was recognized that a change of form also imparted value, it was still denied that a changing of place could be truly productive industry. But when production is seen to be the bringing of things into right relations with wants, transportation may be deemed to be the primary and typical mode of increasing income. Movement is necessary to the existence of animals. The animal, in the order of evolution a higher form of life than the more fixed plants, goes to seek food, and has open to it a wider range of possibilities in life. With slight exceptions, it is true that the only way in which animals can bring about better place-relations between their wants and goods is by moving themselves. To this power man has added that of moving goods and thus adds enormously to income. Agents being valued in accordance with their net productiveness, the nearness to market and the ease of transporting the product are large factors in price. The location of a field enters into its value as truly as do the chemical qualities of the soil. A rocky field near a market may be richer, in an industrial sense, than the richest soil far remote, which can be used by men only at the cost of their alienation from society. Means of transportation set a limit to social and political groupings, to the size of the market, and to the possibility of exchange. Indeed, all exchange value is conditioned upon the possibility of transportation.

2. Natural differences in the grades of fertility and of accessibility determine first the most valued locations. Primitive man, dependent on the bounties of nature, had to take things as he found them. Few places unite the best grades of the essential things: water, food, fertile soil, a favorable climate, protection against enemies. Between tribe and tribe went on ceaseless war for the few favored spots of the earth. Where transportation is possible, trade can supply one or more of the missing elements. International trade began early, wherever it could, to strengthen economically the weak localities. Advantages in transportation are sometimes better than fertile soil and rich resources. The early centers of civilization were on the banks of rivers and the shores of seas. Around the Mediterranean were the ancient empires. Trading-towns grew up at ports and at the favored points of trade: Tyre, Sidon, Carthage, Florence, Genoa, Venice, Antwerp, London, New York. The early settlements in America were grouped along the coast. Without the cheap communication afforded by water, the colonies would have been cut off from the benefits of continuing contact with the older civilization. It would have been a great price to pay, even for a rich continent.

3. The opening up of new water-routes of travel has profoundly altered the prosperity of nations. Sometimes the relation of cause and effect is the reverse of that just noted. The conquest of Asia Minor by the Turks closed the lines of travel with the East, destroyed the trade of the Italian cities, and stimulated exploration for new routes. The War of 1812 in America stopped the coast trade and forced on the wagon-roads between the New England and the Southern states a great traffic, which declined quickly at the close of the war. Again, the growth of population and industry shifts the center of trade, as it did from the south to the north of Europe, and as it is doing from England to America. The discovery of new routes, however, has wrought the most rapid and sweeping changes. These three causes united, about the time of the discovery of America, to overthrow the prosperity of the older cities of Europe, while the opening of the resources in America, the abundance of silver and gold, trade with the colonists and the Indians, showered wealth and trade into the lap of Spain, Holland, Belgium, England, and the northern cities of Germany. Such changes continue under our eyes. The Erie Canal has an influence on values in every township from New York to Buffalo, and along the lake shores to the head of Lake Superior. The Suez Canal marked an epoch in ocean travel. The American Isthmian Canal will affect the value of many investments, from the Gulf of Mexico to the Pacific Coast. A marked change in transportation thus shifts the level of values in a locality. Fortunes are made and lost. One community rises and another sinks. Increments and decrements of value on a great scale are unearned, and all classes of goods are affected, though in varying degrees.
