The Psychological Factor in the Depopulation of Melanesia

W. H. R. Rivers

By the early 1920s the destructive frontier processes documented by the select committee of 1836-37, were dramatically reducing the native population of Melanesia. In the Solomons local populations that had numbered 500 people before 1900 were reduced to less than 100. Where there were 46 villages, there were now only 3. Some areas were totally depopulated. This was occurring throughout the Melanesian region to such a degree that authorities were becoming alarmed over the threat to the future labor force.

In this selection W H. R Rivers refutes charges that such depopulation was caused by problems in tribal cultures themselves and instead shows how colonial intervention increased mortality and decreased fertility. He assumes that under traditional conditions a relative demographic balance existed. According to Rivers, labor recruiting along with a variety of changes in traditional housing, clothing, politics, and domestic life, introduced by well-meaning government administrators and missionaries, caused enormous disruptions. People were losing interest in life. Rivers is apparently not opposed to intervention as such; be merely thinks that introduced changes should be minimally disturbing. For example, in his policy recommendations not included in this selection, Rivers suggests that pig heads might be substituted in rituals requiring human heads and that canoe races might replace the excitement and competition of warfare. Administrators were quick to appreciate the possibilities of these insights, and in 1926 the functionalist anthropologist Radcliffe-Brown, was brought to the University of Sydney to begin a five-year program of training administrators for service in New Guinea and the Pacific. In 1927 the Rockefeller Foundation and the Australian National Research Council established a special Anthropological Research Fund to sponsor more fieldwork. Williams (see part IV) represents the policy approaches that logically followed.

Rivers (1864-1922) held a medical degree and lectured in experimental psychology at Cambridge. He was a member of the Torres Strait ethnological expedition of 1898, and he conducted ethnographic fieldwork among the Todas of India in 1902 and in Melanesia in 1905 and 1914. He was president of the Royal Anthropological Institute at the time of his death in 1922.

The papers by members of the Melanesian Mission and other workers in Melanesia published in this book show conclusively that this great archipelago is undergoing a process of depopulation. In some parts the decline is taking place so rapidly that at no distant date the islands will wholly lose their native inhabitants unless something is done to stay its progress. . . .

Various causes have been given to account for the dying out of the people, different factors having been stressed by different authors. I propose to attempt a more complete survey of the causes which lead to decrease of population

Before beginning this survey it will be well to deal briefly with a supposed fact which has frequently been brought forward as a means of accounting for the decrease of the population of Melanesia. It has been supposed that the Melanesians were already a dying people before the European invasion, and that their decline was due to faults inherent in their own culture. In the first place there is no evidence of any value that the people were decreasing in number before the advent of Europeans.

It may be true that here and there the people already showed signs of diminution on the arrival of the missionaries.1 It must be remembered, however, that the people had already been subject for many years to certain European influence, such as that of the sandal-wood hunters, which were far from being of a harmless kind.

When apologists for the effects of their own civilization give reasons for the supposed original decadence, these often bear their own refutation on the face. Thus, one writer blames the heathen custom of polygamy, but in the same paragraph states that the practice is confined to the few.

Another cause which has been put forward is the special kind of consanguineous union known as the cross-cousin marriage.

This marriage is orthodox in several parts of Melanesia and is especially frequent and important in Fiji. This subject was fully investigated by the Commission that more than twenty years ago inquired into the decrease of the native population of Fiji. In their Report (1896), which forms a store-house of most valuable facts concerning the topics of this book, it is shown conclusively that this factor had not contributed towards Fijian decadence, but rather that these consanguineous marriages were more fruitful than marriage between wholly unrelated persons.

I shall deal presently with native customs in relation to our subject and hope to show that it is rather the indiscriminate and undiscriminating interference with them which stands forth prominently among the causes of decay.

I can now consider the conditions to which real efficacy in the process of destruction can be assigned. In studying this subject the first point to bear in mind is the double character of the factors upon which fluctuation of population depends, a double character which holds good of Melanesia as of more civilized parts of the world. Diminution of population may be due to increase of the death-rate or to decrease of the birth-rate, or to both combined. I can bring forward evidence to show that both factors have been active in Melanesia. I will begin with the conditions that have affected the death-rate.

In a subject in that we can find little on which to pride ourselves, it is satisfactory to be able to exclude one cause of depopulation which has contributed in no small measure to the disappearance of native races in other parts of the world. There has been no deliberate attempt to exterminate the people such as has disgraced the history of our relations with regions more suited to European habitation than the sweltering and unhealthy islands of Melanesia. The injurious influences due to European rulers and settlers have been unwitting. Owing to the need for the labour of those accustomed to the tropics, it has always been in the interests of the settlers that the native population shall be alive and healthy. In so far as native decay is due to European influence we have to lay the blame on ignorance and lack of foresight not on any deliberate wish to destroy.

In considering the death of a people as of an individual, it is natural to think first of disease. Disease is the name we give to a group of processes by which the size of a population is adjusted so as to enable it best to utilize the available means of subsistence. Before the arrival of Europeans, Melanesia had its own diseases, by means of which Nature helped to keep the population within bounds. Everything goes to show that the population of Melanesia was well within the limits that the country was capable of supporting, but it is not so certain that it was far within this capacity in relation to the very simple means the people possessed for exploiting its resources. So far as we can tell, there had been set up a state of equilibrium between the size of the population and the available resources of the country. Recent knowledge goes to show that the diseases due to infective parasites tend to set up a state of tolerance and habituation that renders a people less prone to succumb to their ravages, and there is no reason to suppose that Melanesia was any exception in this respect. Thus the people are largely habituated to the malaria which certainly existed among them before the coming of European influence.

Into this community thus adapted to the infective agents of their of their own country, the invaders brought a number of new diseases; measles, dysentery, probably tubercle and influenza, and last but unfortunately far from least potent, venereal disease. These maladies had effects far more severe than those they bring upon themselves, partly because they found a virgin soil, partly because the native therapeutic ideas were not adapted to the new diseases, so that remedies were often used which actually increased their harmfulness. Many of these introduced diseases are still drawing a large toll on the numbers and energies of the people, the two which seem to be exerting the most steady influence, so far as my observations show, being dysentery and tubercle.

A second group of introduced causes of destruction is composed of what maybe called the social poisons, such as alcohol and opium. Though it is possible that the people use tobacco somewhat to excess, the only poison that needs to be considered in Melanesia is alcohol. In certain parts of Melanesia there is no question that it has exerted in the past and is still exerting a most deleterious influence, but it is satisfactory to be able to say that its noxious influence has been reduced to negligible importance in those parts of the archipelago wholly subject to British rule, where it is penal to sell or give alcohol to a native. Alcohol is still, however, potent as a cause of disease and death in the New Hebrides. In those islands there are regulations against the sale of alcohol to natives, but under the present Condominium Government they are not obeyed.

A third direct cause of increase of death rate is the introduction of firearms, of which the comparatively harmless warfare of the natives is given a far more deadly turn. This cause is still active to some extent in the New Hebrides owing to breaking of the regulations of the Condominium Government, but fire-arms have never had great importance as an instrument of destruction in Melanesia.

I come to a more serious cause when I consider European influence upon native customs. I begin with one that excites perennial interest whenever native welfare is discussed. Before the advent of Europeans the people of some islands went wholly nude or wore only garments, if they can be so called, which fulfilled neither of the two chief purposes for which the clothing of civilized people is designed. In other parts the native clothing consisted of petticoats, loincloths, or other simple garments thoroughly adapted to the necessities of the climate. One of the first results of European influence was the adoption of the clothing of the visitors, and clothes were adopted in such a manner as to accentuate the evils that they necessarily brought with them. The Melanesian is not uncleanly. He bathes frequently, and where he preserves his native mode of clothing, his ablutions are amply sufficient for cleanliness. When he wears European garments, he fails to adopt measures, such as the frequent change of clothing, which then become necessary. He continues to bath in his clothes, and instead of changing his garments frequently, wears them continuously till they are ragged, and even when new clothing is obtained, it is put over the old.

It is a great Mistake, often made, to blame the missionaries for this use of foreign clothing. It is true that its use was directly encouraged by the early missionaries, but this encouragement was unnecessary. To the native, trousers and coats are the distinctive mark of the white man, and nothing short of prohibition could have prevented their use. Where we can now see the missionaries to have been at fault is that they did not recognize the evil of the innovation and set themselves steadily to minimize it. They should have insisted upon attention to the elementary principles of the hygiene which the use of clothes involves.

At the present time the influence of missionaries is steadily directed to this end. Having been privileged to live among missionaries of different schools of thought in Melanesia, I can testify that no subject is more frequently discussed and more thoroughly and anxiously considered than how to lessen the use and injurious influence of European clothing.

Another modification of native custom, which is less widely recognized, but in my experience quite as much in need of consideration at the present time, is housing. The native Melanesian house is usually rainproof and of good proportions, while owing to its mode of construction it is well ventilated and thoroughly adapted to the climate. Instead of being content with houses of similar construction or with houses of the kind used by Europeans living in other tropical countries, settlers have built houses with thick walls and very imperfect means of ventilation. These have in some cases been copied by the natives, or even built by the missionaries for the use of their followers. Such buildings might have been specially devised for the propagation of tubercle, and if they are allowed to be built will certainly increase the already far too heavy ravages of this disease.

The modifications of housing and clothing that I have just considered touch especially the material side of life. I have now to consider a number of modifications and interferences with native custom which I believe to have been quite as important if not more important in the production of native decadence. When Melanesia became subject to Europeans, magistrates and missionaries were sent to rule and direct the lives of the people. They found in existence a number of institutions and customs which were, or seemed to them to be, contrary to the principles of morality. Such customs were usually forbidden without any inquiry into their real nature without knowledge of the part they took in native life, and without any attempt to discriminate between their good and bad elements. Thus, in the Solomon Islands the rulers stopped the special kind of warfare known as head-hunting, with out at all appreciating the vast place it took in the religious and ceremonial lives of the people, without realizing the gap it would leave in their daily interests, a blank far more extensive than that due to the mere cessation of a mode of warfare. Again, in Fiji, the custom according to which the men of the community slept apart from the women in a special house, a widespread custom in Melanesia, seemed to the missionaries contrary to the ideals of the Christian family, and the custom was stopped or discouraged without it being realized that the segregation of the sexes formed an effectual check on too free intercourse between them.

In the New Hebrides again, the missionaries put an end to, or where they did not destroy, treated with a barely veiled contempt a highly complicated organization arising out of beliefs connected with the cult of dead ancestors. In some cases it was apparent enough that the institution with all its elaborate ceremonial was heathen and prejudiced church attendance, while elsewhere stress was laid on occasional revels and dances which gave opportunity for licence. It was not recognized that in forbidding or discouraging without inquiry, they were destroying institutions that had the most far-reaching ramifications through the social and economical life of the people.

If these and similar institutions had been studied before they were destroyed or discouraged, it would have been found possible to discriminate between those features which were noxious and needed repression or amendment, and those which were beneficial to the welfare of the community. Even when their destruction was deemed necessary, something could have been done to replace the social sanctions of which the people were thus deprived. The point I wish to emphasis is that through this unintelligent and undiscriminating action towards native institutions, the people were deprived of nearly all that gave interest to their lives. I have now to suggest that this loss of interest forms one of the reasons, if indeed it be not the most potent of all the reasons, to which the native decadence is due.

It may at first sight seem farfetched to suppose that such a factor as loss of interest in life could ever produce the dying out of a people, but my own observations have led me to the conclusion that its influence is so great that it can hardly be overrated. I venture therefore to consider it at some length.

When you inquire of those who have lived long in Melanesia concerning the illness and mortality of the natives, you are struck by the frequency of reference to the ease with which the native dies. Over and over again one is told of a native who seemed hale and well until, after a day or two of some apparently trivial illness, he gives up the ghost without any of the signs which among ourselves usually give ample warning of the impending fate. A native who is ill loses heart at once. He has no desire to live, and perhaps announces that be is going to die when the onlooker can see no ground for his belief.

The matter becomes more easy to understand if we consider the ease with which the people are killed by magic or as the result of the infraction of a taboo. The evidence is overwhelming that such people as the Melanesians will sicken and die in a few hours or days as the result of the belief that an enemy has chosen them as the victim of his spells, or that they have, wittingly or unwittingly, offended against some religious taboo. If people who are interested in life and do not wish to die can be killed in a few days or even hours by a mere belief, how much more easy it is to understand that a people who have lost all interest in life should become the prey of any morbid agency acting through the body as well as through the mind. It is this evidence of the enormous influence of the mind upon the body among the Melanesians and other lowly peoples that first led me to attach so much importance to loss of interest as the primary cause of their dying out. Once this belief has been formulated, there is seen to be much definite evidence in Melanesia to support it

Certain islands and districts of Melanesia show a degree of vitality in striking contrast with the rest. These exceptional cases fall into two classes: one includes those islands or parts of islands where the people have so far been fierce and strong enough to withstand European influence. There are still certain parts in Melanesia that as yet the footprint of the white man has not reached, and others where, after successful encounters with punitive expeditions, the people still believe themselves to be a match for the invader. Here the old zest and interest in life persist and the people are still vigorous and abundant.

The other group of peoples who show signs of vitality are those who have adopted Christianity, not merely because it is the religion of the powerful white man, but with a wholehearted enthusiasm which has given them a renewed interest in life. Here the numbers are increasing after an initial drop. Christianity and the occupations connected with it have given the people a new interest to replace that of their indigenous culture, and with this interest has come the desire to live.

The special point I wish to make in my contribution to this book is that interest in life is the primary factor in the welfare of a people. The new diseases and poisons, the innovations in clothing, housing and feeding, are only the immediate causes of mortality. It is the loss of interest in life underlying these more obvious causes which gives them their potency for evil and allows them to work such ravages upon life and health.

I can pass to the second of the two groups of influences by which a people decline in number, having so far dealt only with those which increase the death-rate. I have now to consider those which produce decline by diminishing the birth-rate and will begin by stating briefly the evidence that this factor has played and is playing a part in the dying out of the Melanesians. This evidence has been gained by a mode of inquiry adopted originally for purely scientific purposes. When in Torres Straits with Dr. Haddon twenty-four years ago, I discovered that the people preserved in their memories with great fidelity a full and accurate record of their descent and relationships (Rivers 1910). It was possible to collect pedigrees so ample in all collateral lines that they could serve as a source of statistical inquiry into such features as the average size of a family, infant mortality, and other subjects that furnish the basis for conclusions concerning fluctuations of population. I have found this interest in genealogy wherever I have worked, and the collection of pedigrees has always formed the basis of my ethnographic inquiries. In Melanesia this instrument shows conclusively that the fall in numbers is due quite as much to decrease of the birthrate as to increase in the death rate.

The two islands which show this striking fall in birthrate are of especial interest in that in them, and especially in Eddystone, the chief factors to which the dying out of peoples is usually ascribed are absent. In Eddystone, about which a residence of several months enables me to speak with confidence, there is no record of any very severe epidemics. Tubercle and dysentery the two most deadly diseases in Melanesia, do not appear to be, or to have been, especially active; and though both the chief forms of venereal disease exist in the island, they do not seem to have done any great amount of mischief. The island has never had a white missionary; the people still wear their native dress and live in houses of native build. Alcohol is little known and other poisons not at all, while any effect of firearms on mortality is negligible. Few of the people have left the island as labour or for any other reason. All the factors to which other writers in this book ascribe the decrease of the population of Melanesia are practically absent and yet we have a striking diminution of population, due in the main to decrease of the birthrate.

If now we pass from material to mental factors, the decrease in the birth-rate becomes easier to understand. No one could be long in Eddystone without recognizing how great is the peopleÂ’s lack of interest in life and to what an extent the zest has gone out of their lives. This lack of interest is largely due to the abolition of headhunting by the British government. This practice formed the centre of a social and religious institution that took an all-pervading part in the lives of the people. The heads sought in the head-hunting expeditions were needed in order to propitiate the ancestral ghosts on such occasions as building a new house for a chief or making a new canoe, while they were also offered in sacrifice at the funeral of a chief. Moreover, headhunting was not only necessary for the due performance of the religious rites of the people, but it stood in the closest relation to pursuits of an economic kind. The actual headhunting expedition only lasted a few weeks, and the actual fighting often only a few hours, but this was only the culminating point of a process lasting over years. It was the rule that new canoes should be made for an expedition to obtain heads, and the manufacturing of these meant work of an interesting kind lasting certainly for many months, probably for years. The process of canoe-building was accompanied throughout by rites and feasts which not only excited the liveliest interest but also acted as stimuli to various activities of horticulture and pig-breeding. As the date fixed for the expedition approached other rites and feasts were held, and these were still more frequent and on a larger scale after the return of a successful expedition. In stopping the practice of head-hunting the rulers from an alien culture were abolishing an institution which had its roots in the religion of the people and spread its branches throughout nearly every aspect of their culture, and by this action they deprived the people of the greater part of their interest in life, while at the same time they undermined the religion of the people without any attempt to put another in its place.

I need only consider here very briefly the agencies to which this fall in birth-rate is due. It is well known that certain forms of venereal disease will produce sterility, and it is noteworthy that the dying out of the people of Vulua is ascribed by their neighbours to the ravages of this disease brought by returning labourers from Queensland. There is little doubt, however, that if we take Melanesia as a whole, causes of this kind are trivial or of slight importance as compared with voluntary restriction. Throughout Melanesia the people are acquainted with various means of producing abortion and also practice measures which they believe to prevent conception, and processes of this kind almost certainly form the main agencies in lowering the birthrate. We have here only another effect of the loss of interest in life that I have held to be so potent in enhancing mortality. The people say themselves: "Why should we bring children into the world only to work for the white man." Measures which, before the coming of the European, were used chiefly to prevent illegitimacy have become the instrument of racial suicide

It is satisfactory that before I leave this subject I am able to point to a brighter side. I have already said that in certain parts of Melanesia the downward movement has been arrested and that the people now show signs of growth. I mentioned also that this was occurring especially in islands where the people have really taken to their hearts the lessons of their Christian teachers.

The teachings of the missionaries concerning the evils of racial suicide may possibly have contributed in some degree to this recovery, though I doubt whether in general they have been aware of the part which voluntary restriction has taken. I believe that their influence has lain much more in the fact that the religion they have taught has given the people a renewed interest in life that has again made it worth while to bring children into the world.

Until now I have said nothing of a cause of depopulation which has been especially active in Melanesia. The causes I have so far considered have been treated under two headings, according as they have enhanced the death rate or lowered the birthrate. The labour-traffic which I have now to consider is more complex and involves both of these factors.

In dealing with this cause of depopulation it is well that it is possible to begin by distinguishing between the traffic as it was and as it is. It would be difficult to exaggerate the evil influence of the process by which the natives of Melanesia were taken to Australia and elsewhere to labour for the white man. It forms one of the blackest of civilization's crimes. Not least among its evils was the manner of its ending, when large numbers of people who had learnt by many years' experience to adapt themselves to civilized ways were, in the process of so-called repatriation, thrust back into savagery without help of any kind. The misery thus caused and the resulting disaffection not only underlie most of the open troubles in the recent history of Melanesia, but by the production of a state of helplessness and hopelessness have contributed as much as any other factors to the decline of the population.

I must not, however, dwell on the crimes and mistakes of the past. Our object in this book is to call attention to existing evils in the hope that they may be remedied before it is too late. At the present time Melanesians are only recruited as labourers to work within the confines of Melanesia, and both the recruitment and the conditions of labour are subject to Government control. Its grosser evils have been removed, at any rate in those parts of Melanesia which are wholly governed by Great Britain, though it would appear that there are still very grave defects in those parts of Melanesia under the control of the Condominium Government. But, however closely and wisely the traffic is controlled, the removal from their own homes of the younger men, and still more of the younger women, of a declining population is not a factor which can tend to arrest the decline or convert it into a movement in the opposite direction. Even in its improved form, and limited to Melanesia though it be, the labour traffic continues to act as a cause of depopulation It acts directly by taking men and women away from their homes when they should be marrying and producing children, while other evils are that, as at present conducted, the traffic tends to spread disease and to undermine an influence which I believe to be at the present time the most potent for good in Melanesia, the work of the missionaries. Moreover, the use of natives as labourers on plantations fails to give that interest in life that, as I have tried to show, forms the most essential factor in maintaining the health of a people.
