It is but natural that such meetings should bring about barter. Perhaps this explains the origin of those “weekly fairs held by the Negroes of Central Africa in the midst of the primæval forest under special arrangements for the peace,”[66] and likewise the great fairs, said to be very ancient, of the fur hunters of the extreme north of the Tschuktsche.

All these things presuppose the development of pacific forms of intercourse between neighboring groups. These forms are to be found almost universally. They could very easily be developed at this period, since the discovery had not yet been made that men can be utilized as labor motors. At this stage, the stranger is treated as an enemy only in doubtful cases. If he comes with apparently peaceable intent, he is treated as a friend. Therefore, a whole code of public law ceremonies grew up, intended to demonstrate the pacific intent of the newcomer.[K] One puts aside one’s arms and shows one’s unarmed hand, or one sends heralds in advance, who are always inviolable.

[K] In this category must be reckoned the salutation, still in use in some parts, “Peace Be With You.” It is expressive of the perversity of Tolstoi’s later years that he misapprehends this characteristic mark of a time when war was the normal state of affairs, as the remnant of a golden age of peace. The Importance of the Russian Revolution (German translation by A. Hess, p. 17).

It is clear that these forms represent some kind of claim to hospitality, and in fact it is by this guest-right that peaceful trade is first made possible. The exchange of guest-gifts precedes, and appears to introduce, barter proper. It becomes, therefore, important to investigate the source of hospitality.

Westermarck, in his recent monumental work (1907), Origin and Development of Moral Concepts,[68] states that the custom of hospitality results from two causes, curiosity for news from the stranger from afar, and still more from the fear that the stranger may be endowed with powers of sorcery, imputed to him just because he is a stranger.[L] In the Bible, hospitality is recommended for the reason that one can not know that the stranger may not be an angel. The superstitious race fears his curse (the Erinys of the Greeks) and hastens to propitiate the stranger. Having been accepted as a guest he is inviolable and enjoys the sacred right of the blood-related group, and is regarded as belonging to it during his stay. Therefore he partakes of the benefits of the aboriginal communism reigning in the group, and shares its property. The host demands and receives whatever he claims, the stranger obtains in turn what he asks for. When the peaceable intercourse becomes more frequent, the mutual giving of guest-presents may develop into a trading arrangement, because the trader gladly returns to the spot where he found good entertainment and a profitable exchange and where he is protected by the laws of hospitality, instead of seeking new places, where, often with danger to his life, he would first have to acquire the right to hospitality.

[L] This may account for the use made of old women as heralds. They are doubly available for that purpose, since they are worthless for warfare, and are supposed to be endowed with specific powers of sorcery (Westermarck), even more than old men, who also are treated cautiously, since they may soon become “ghosts.”

The existence of an “international” division of labor is, of course, presupposed before the development of a regular trade relation can begin. Such a division of labor exists much earlier and to a greater extent than is generally believed. “It is quite erroneous to suppose that the division of labor takes place only on a high scale of economic development. There are in the interior of Africa villages of iron-smiths, nay, of such as only turn out dart-knives; New Guinea has its villages of potters, North America its arrow-head makers.”[69] From such specialties there develops trade, whether through roving merchants, or by gifts to one’s hosts, or by peace-gifts from tribe to tribe. In North America, the Kaddu trade in bows. “Obsidian was universally employed for arrow heads and knives; on the Yellowstone, on the Snake River, in New Mexico, but especially in Mexico. Thence the precious article was distributed all over the entire country as far as Ohio and Tennessee, a distance of nearly two thousand miles.”[70]

According to Vierkandt: “From the purely home-made products of primitive peoples, there results a system of trade totally distinct from that prevailing under modern conditions.... Each separate tribe has developed special aptitudes, leading to interexchange. Even among the comparatively uncivilized Indian tribes of South America, we find such differentiations.... By such a trade, products may be distributed over extraordinary distances, not in any direct way through professional traders, but through a gradual passing along from tribe to tribe. The origin of such a trade, as Buecher has shown, is to be traced back to the exchange of guest-gifts.”[71]

Besides this exchange of guest-gifts, a trade may grow from the peace offerings which adversaries after a fight exchange as a sign of reconciliation. Sartorius reports on Polynesia: “After a war between different islands, the peace offerings for each group were something novel; and if the present and return present pleased both parties, a repetition took place, and thus again the way for exchange of products was opened. But, these, in contrast to guest-gifts, were the bases of continuing intercourse. Here, in place of the contact of individuals, tribes and peoples met. Women are the first object of barter; they form the connecting link between strange tribes, and according to evidence from many sources, women are exchanged for cattle.”[72]

We meet here an object of trade, exchangeable even without “international division of labor.” And it appears as though the exchange of women had, in many ways, smoothed the way for the traffic in merchandise, as though it had been the first step toward the peaceable integration of tribes, which accompanied the warlike integration of the formation of the State. Lippert, however, believes that the peaceful exchange of fire antedates this barter.[73] Conceding that this custom is very ancient, he can nevertheless trace it only from rudiments of observances and of law; and since proof is no longer accessible, we shall not pursue the question further in this place.
