The coastal populations of the South Sea Islands, with very few exceptions, are, or were before their extinction, expert navigators and traders. Several of them had evolved excellent types of large sea-going canoes, and used to embark in them on distant trade expeditions or raids of war and conquest. The Papuo-Melanesians, who inhabit the coast and the out-lying islands of New Guinea, are no exception to this rule. In general they are daring sailors, industrious manufacturers, and keen traders. The manufacturing centres of important articles, such as pottery, stone implements, canoes, fine baskets, valued ornaments, are localised in several places, according to the skill of the inhabitants, their inherited tribal tradition, and special facilities offered by the district; thence they are traded over wide areas, sometimes travelling more than hundreds of miles.

Definite forms of exchange along definite trade routes are to be found established between the various tribes. A most remarkable form of intertribal trade is that obtaining between the Motu of Port Moresby and the tribes of the Papuan Gulf. The Motu sail for hundreds of miles in heavy, unwieldy canoes, called lakatoi, which are provided with the characteristic crab-claw sails. They bring pottery and shell ornaments, in olden days, stone blades, to Gulf Papuans, from whom they obtain in exchange sago and the heavy dug-outs, which are used afterwards by the Motu for the construction of their lakatoi canoes.[1]

Further East, on the South coast, there lives the industrious, sea-faring population of the Mailu, who link the East End of New Guinea with the central coast tribes by means of annual trading expeditions.[2] Finally, the natives of the islands and archipelagoes, scattered around the East End, are in constant trading relations with one another. We possess in Professor Seligman’s book an excellent description of the subject, especially of the nearer trades routes between the various islands inhabited by the Southern Massim.[3] There exists, however, another, a very extensive and highly complex trading system, embracing with its ramifications, not only the islands near the East End, but also the Louisiades, Woodlark Island, the Trobriand Archipelago, and the d’Entrecasteaux group; it penetrates into the mainland of New Guinea, and exerts an indirect influence over several outlying districts, such as Rossel Island, and some parts of the Northern and Southern coast of New Guinea. This trading system, the Kula, is the subject I am setting out to describe in this volume, and it will be seen that it is an economic phenomenon of considerable theoretical importance. It looms paramount in the tribal life of those natives who live within its circuit, and its importance is fully realised by the tribesmen themselves, whose ideas, ambitions, desires and vanities are very much bound up with the Kula.

Before proceeding to the account of the Kula, it will be well to give a description of the methods used in the collecting of the ethnographic material. The results of scientific research in any branch of learning ought to be presented in a manner absolutely candid and above board. No one would dream of making an experimental contribution to physical or chemical science, without giving a detailed account of all the arrangements of the experiments; an exact description of the apparatus used; of the manner in which the observations were conducted; of their number; of the length of time devoted to them, and of the degree of approximation with which each measurement was made. In less exact sciences, as in biology or geology, this cannot be done as rigorously, but every student will do his best to bring home to the reader all the conditions in which the experiment or the observations were made. In Ethnography, where a candid account of such data is perhaps even more necessary, it has unfortunately in the past not always been supplied with sufficient generosity, and many writers do not ply the full searchlight of methodic sincerity, as they move among their facts and produce them before us out of complete obscurity.

It would be easy to quote works of high repute, and with a scientific hall-mark on them, in which wholesale generalisations are laid down before us, and we are not informed at all by what actual experiences the writers have reached their conclusion. No special chapter or paragraph is devoted to describing to us the conditions under which observations were made and information collected. I consider that only such ethnographic sources are of unquestionable scientific value, in which we can clearly draw the line between, on the one hand, the results of direct observation and of native statements and interpretations, and on the other, the inferences of the author, based on his common sense and psychological insight.[4] Indeed, Some such survey, as that contained in the table, given below ([Div. VI of this chapter]) ought to be forthcoming, so that at a glance the reader could estimate with precision the degree of the writer’s personal acquaintance with the facts which he describes, and form an idea under what conditions information had been obtained from the natives.

Again, in historical science, no one could expect to be seriously treated if he made any mystery of his sources and spoke of the past as if he knew it by divination. In Ethnography, the writer is his own chronicler and the historian at the same time, while his sources are no doubt easily accessible, but also supremely elusive and complex; they are not embodied in fixed, material documents, but in the behaviour and in the memory of living men. In Ethnography, the distance is often enormous between the brute material of information—as it is presented to the student in his own observations, in native statement, in the kaleidoscope of tribal life—and the final authoritative presentation of the results. The Ethnographer has to traverse this distance in the laborious years between the moment when he sets foot upon a native beach, and makes his first attempts to get into touch with the natives, and the time when he writes down the final version of his results. A brief outline of an Ethnographer’s tribulations, as lived through by myself, may throw more light on the question, than any long abstract discussion could do.
