but in Mexico and other parts of North America, particularly in the Lake Superior region; but as the soft hematite iron was found in larger quantities in a free state, it would seem that the use of iron in a small degree must have occurred at about the same time, or perhaps a little later. The process of smelting must have been suggested by the action of fire built on or near ore beds, where a crude process of accidental smelting took place. Combined with tin ore, the copper was made into bronze in Peru and Mexico at the time of the discovery. In Europe there are abundant remains to show the early use of metals. Probably copper and tin were in use before iron, although iron may have been discovered first. There are numerous tin mines in Asia and copper mines in Cyprus. At first, metals were probably worked while cold through hammering, the softest metals doubtless being used before others.

      It is difficult to tell how smelting was discovered, although the making and use of bronze implements is an indication of the first process of smelting ores and combining metals. When tin was first discovered is not known, but we know that bronze implements made from an alloy of copper, tin, and usually other metals were used by the Greeks and other Aryan peoples in the early historic period, about six thousand years ago. In Egypt and Babylon many of the inscriptions make mention of the use of iron as well as bronze, although the extended use of the former must have come about some time after the latter. At first all war instruments were stone and wood and later bronze, which were largely replaced by iron at a still later period. The making of spears, swords, pikes, battle-axes, and other implements of war had much to do with the development of ingenious work in metals. The final perfection of metal work could only be attained by the manufacture of finely treated steel. Probably the tempering of steel began at the time iron came prominently into use.

      Other metals, such as silver, quicksilver, gold, and lead, came into common use in the early stages of civilization, all of which added greatly to the arts and industries. Nearly all of the metals were used for money at various times. The aids to trade and commerce which these metals gave on account of their universal use and constant measure of value cannot be overestimated.

      Transportation as a Means of Economic Development. – Early methods of carrying goods from one place to another were on the backs of human beings. Many devices were made for economy of service and strength in carrying. Bands over the shoulders and over the head were devised for the purpose of securing the pack on the back. An Indian woman of the Southwest would carry a large basket, or keiho, on her back, secured by a band around her head for the support of the load. A Pueblo woman will carry a large bowl filled with water or other material, on the top of her head, balancing it by walking erect. Indeed, in more recent times washerwomen in Europe, and of the colored race in America, carry baskets of clothes and pails of water on their heads. The whole process of the development of transportation came about through invention to be relieved from this bodily service.

      As the dog was the first animal domesticated, he was early used to help in transportation by harnessing him to a rude sled, or drag, by means of which he pulled articles from one place to another. The Eskimos have used dogs and the sled to a greater extent than any other race. The use of the camel, the llama, the horse, and the ass for packing became very common after their domestication. Huge packs were strapped upon the backs of these animals, and goods thus transported from one place to another. To such an extent was the camel used, even in the historic period, for transportation in the Orient that he has been called the "ship of the desert." The plains Indians had a method of attaching two poles, one at each side of an Indian pony, which extended backward, dragging on the ground. Upon these poles was built a little platform, on which goods were deposited and thus transported from one camp to another.

      It must have been a long time before water transportation performed any considerable economic service. It is thought by some that primitive man conceived the idea of the use of water for transportation through his experience of floating logs, or drifts, or his own process of swimming and floating. Jack London pictures two primitives playing on the logs near the shore of a stream. Subsequently the logs cast loose, and the primitives were floated away from the shore. They learned by putting their hands in the water and paddling that they could make the logs move in the direction which they wished to go. Perhaps this explanation is as good as any, inasmuch as the beginnings of modern transportation still dwell in the mist of the past. However, in support of the log theory is the fact that modern races use primitive boats made of long reeds tied together, forming a loglike structure. The balsa of the Indians of the north coasts of South America is a very good representation of this kind of boat.

      Evidently, the first canoes were made by hollowing logs and sharpening the ends at bow and stern. This form of boat-making has been carried to a high degree of skill by the Indians of the northwest coast of America and by the natives of the Hawaiian Islands. The birch-bark canoe, made for lighter work and overland transportation, is more suggestive of the light reed boat than of the log canoe. Also, the boats made of a framework covered with the skins of animals were prominent at certain periods of the development of races who lived on animal food. But later the development of boats with frames covered with strips of board and coated with pitch became the great vehicle of commerce through hundreds of years. It certainly is a long journey from the floating log to the modern floating passenger palace, freight leviathan, or armed dreadnought, but the journey was accomplished by thousands of steps, some short and some long, through thousands of years of progress.

      Trade, or Exchange of Goods. – In Mr. Clark Wissler's book on Man and Culture, he has shown quite conclusively that there are certain culture areas whereby certain inventions, discoveries, or customs have originated and spread over a given territory. This recognition of a centre of origin of custom or invention is in accordance with the whole process of social development. For instance, in a given area occupied by modern civilized people, there are a very few who invent or originate things, and others follow through imitation or suggestion. So it was with the discoveries and inventions of primitive man. For example, we know that in Oklahoma and Arkansas, as well as in other places in the United States, certain stone quarries or mines are found that produce a certain kind of flint or chert used in making arrow-heads or spearheads and axes. Tribes that developed these traded with other tribes that did not have them, so that from these centres implements were scattered all over the West. A person may pick up on a single village site or battle-ground different implements coming from a dozen or more different quarries or centres and made by different tribes hundreds of miles apart in residence.

      This diffusion of knowledge and things of material workmanship, or of methods of life, is through a system of borrowing, trading, or swapping – or perhaps sometimes through conquest and robbery; but as soon as an article of any kind could be made which could be subjected to general use of different tribes in different localities, it began to travel from a centre and to be used over a wide area. Certain tribes became special workers in specialized lines. Thus some were bead-makers, others expert tanners of hides, others makers of bows and arrows of peculiar quality, and others makers of stone implements. The incidental swapping of goods by tribes finally led to a systematic method of a travelling trader who brought goods from one tribe to another, exchanging as he went. This early trade had an effect in more rapid extension of culture, because in that case one tribe could have the invention, discovery, and art of all tribes. In connection with this is to be noted the slow change of custom regarding religious belief and ceremony or tribal consciousness. The pride of family and race development, the assumption of superiority leading to race aversion, interfered with intelligence and the spread of ideas and customs; but most economic processes that were not bound up with religious ceremonies or tribal customs were easily exchanged and readily accepted between the tribes.

      Exchange of goods and transportation went hand in hand in their development, very slowly and surely. After trade had become pretty well established, it became necessary to have a medium of exchange. Some well-known article whose value was very well recognized among the people who were trading became the standard for fixing prices in exchange. Thus, in early Anglo-Saxon times the cow was the unit of the measure of value. Sometimes a shell, as a cowrie of India or the wampum of the American Indian, was used for this purpose. Wheat has been at one time in America, and tobacco in another, a measure of exchange because of the scarcity of money.

      Gradually, as the discovery and use of precious metals became common and desirable because of their brightness and service in implement and ornament,
