Patrols of the Australian Government venturing into the "uncontrolled" central highlands of New Guinea in 1946 found the primitive people there swept up in a wave of religious excitement. Prophecy was being fulfilled: The arrival of the Whites was the sign that the end of the world was at hand. The natives proceeded to butcher all of their pigs-animals that were not only a principal source of subsistence but also ,symbols of social status and ritual preeminence in their culture. They killed these valued animals in expression of the belief that after three days of darkness "Great Pigs" would appear from the sky. Food, firewood and other necessities had to be stock-piled to see the people through to the arrival of the Great Pigs. Mock wireless antennae of bamboo and rope had been erected to receive in advance the news of the millennium. Many believed that with the great event they would exchange their black skins for white ones.

This bizarre episode is by no means the single event of its kind in the murky history of the collision of European civilization with the indigenous cultures of the southwest Pacific. For more than 100 years traders and missionaries have been reporting similar disturbances among the peoples of Melanesia, the group of Negro-inhabited islands (including New Guinea, Fiji, the Solomons and the New Hebrides) lying between Australia and the open Pacific Ocean. Though their technologies were based largely upon stone and wood, these peoples had highIy developed cultures, as measured by the standards of maritime and agricultural ingenuity, the complexity of their varied social organizations and the elaboration of religious belief and ritual. They were nonetheless ill prepared for the shock of the encounter with the Whites, a people so radically different from themselves and so infinitely more powerful. The sudden transition from the society of the ceremonial stone ax to the society of sailing ships and now of airplanes has not been easy to make.

After four centuries of Western expanSion, the densely populated central highlands of New Guinea remain one of the few regions where the people still carry on their primitive existence in complete independence of the world outside. Yet as the agents of the Australian Government penetrate into ever more remote mountain valleys, they find these backwaters of antiquity already deeply disturbed by contact with the ideas and artifacts of European civilization. For "cargo" -Pidgin English for trade goods has long flowed along the indigenous channels of communication from the seacoast into the wilderness. With it has traveled the frightening knowledge of the white man's magical power. No small element in the white man's magic is the hopeful message sent abroad by his missionaries: the news that a Messiah will come and that the present order of Creation will end.

The people of the central highlands of New Guinea are only the latest to be gripped in the recurrent religious frenzy of the "cargo cults." However variously embellished with details from native myth and Christian belief, these cults all advance the same central theme: the world is about to end in a terrible cataclysm. Thereafter God, the ancestors or some local culture hero will appear and inaugurate a blissful paradise on earth. Death, old age, illness and evil will be unknown. The riches of the white man will accrue to the Melanesians.

Although the news of such a movement in one area has doubtless often inspired similar movements in other areas, the evidence indicates that these cults have arisen independently in many places as parallel responses to the same enormous social stress and strain. Among the movements best known to students of Melanesia are the "Taro Cult" of New Guinea, the "Vailala Madness" of Papua, the "Naked Cult" of Espiritu Santo, the "John Frum Movement" of the New Hebrides and the "Tuka Cult" of the Fiji Islands.

At times the cults have been so well organized and fanatically persistent that they have brought the work of government to a standstill. The outbreaks have often taken the authorities completely by surprise and have confronted them with mass opposition of an alarming kind. In the 1930s, for example, villagers in the vicinity of Wewak, New Guinea, were stirred by a succession of "Black King" movements. The prophets announced that the Europeans would soon leave the island, abandoning their property to the natives, and urged their followers to cease paying taxes, since the government station was about to disappear into the sea in a great earthquake. To the tiny community of Whites in charge of the region, such talk was dangerous. The authorities jailed four of the prophets and exiled three others. In yet another movement, that sprang up in declared opposition to the local Christian mission, the cult leader took Satan as his god.

Troops on both sides in World War II found their arrival in Melanesia heralded as a sign of the Apocalypse. The G.I.s who landed in the New Hebrides, moving up for the bloody fighting on Guadalcanal, found the natives furiously at work preparing airfields, roads and docks for the magic ships and planes that they believed were coming from "Rusefel" (Roosevelt), the friendly king of America.

The Japanese also encountered millenarian visionaries during their southward march to Guadalcanal. Indeed, one of the strangest minor military actions of World War II occurred in Dutch New Guinea, when Japanese forces had to be turned against the local Papuan inhabitants of the Geelvink Bay region. The Japanese had at first been received with great joy, not because their "Greater East Asia Co-Prosperity Sphere" propaganda had made any great impact upon the Papuans, but because the natives regarded them as harbingers of the new world that was dawning, the Right of the Dutch having already given the first sign. Mansren, creator of the islands and their peoples, would now return, bringing with him the ancestral dead. All this had been known, the cult leaders declared, to the crafty Dutch, who had torn out the first page of the Bible where these truths were inscribed. When Mansren returned, the existing world order would be entirely overturned. White men would turn black like Papuans, Papuans would become Whites; root crops would grow in trees, and coconuts and fruits would grow like tubers. Some of the islanders now began to draw together into large "towns"; others took Biblical names such as "Jericho" and "Galilee" for their villages. Soon they adopted military uniforms and began drilling. The Japanese, by now highly unpopular, tried to disarm and disperse the Papuans; resistance inevitably developed. The climax of this tragedy came when several canoe-loads of fanatics sailed out to attack Japanese warships, believing themselves to be invulnerable by virtue of the holy water with which they had sprinkled themselves. But the bullets of the Japanese did not turn to water, and the attackers were mowed down by machine-gun fire.

Behind this incident lay a long history. As long ago as 1857 missionaries in the Geelvink Bay region had made note of the story of Mansren. It is typical of many Melanesian myths that became confounded with Christian doctrine to form the ideological basis of the movements. The legend tells how long ago there lived an old man named Manamakeri ("he who itches"), whose body was covered with sores. Manamakeri was extremely fond of palm wine, and used to climb a huge tree every day to tap the liquid from the flowers. He soon found that someone was getting there before him and removing the liquid. Eventually he trapped the thief, who turned out to be none other than the Morning Star. In return for his freedom, the Star gave the old man a wand that would produce as much fish as he liked, a magic tree and a magic staff. If he drew in the sand and stamped his foot, the drawing would become real. Manamakeri, aged as he was, now magically impregnated a young maiden; the child of this union was a miracle-child who spoke as soon as he was born. But the maiden's parents were horrified, and banished her, the child and the old man. The trio sailed off in a canoe created by Mansren ("The Lord"), as the old man now became known. On this journey Mansren rejuvenated himself by stepping into a fire and flaking off his scaly skin, which changed into valuables. He then sailed around Geelvink Bay, creating islands where he stopped, and peopling them with the ancestors of the present-day Papuans.

The Mansren myth is plainly a creation myth fu II of symbolic ideas relating to fertility and rebirth. Comparative evidence-especially the shedding of his scaly skin-confirms the suspicion that the old man is, in fact, the Snake in another guise. Psychoanalytic writers argue that the snake occupies such a prominent part in mythology the world over because it stands for the penis, another fertility symbol. This may be so, but its symbolic significance is surely more complex than this. It is the "rebirth" of the hero, whether Mansren or the Snake, that exercises such universal fascination over men's minds.

The 19th-century missionaries thought that the Mansren story would make the introduction of Christianity easier, since the concept of "resurrection," not to mention that of the "virgin birth" and the "second coming," was already there. By 1867, however, the first cult organized around the Mansren legend was reported.

Though such myths were widespread in Melanesia, and may have sparked occasional movements even in the preWhite era, they took on a new significance in the late 19th century, once the European powers had finished parceling out the Melanesian region among themselves. In many coastal areas the long history of "blackbirding"-the seizure of islanders for work on the plantations of Australia and Fiji-had built up a reservoir of hostility to Europeans. In other areas, however, the arrival of the Whites was accepted, even welcomed, for it meant access to bully beef and cigarettes, shirts and paraffin lamps, whisky and bicycles. It also meant access to the knowledge behind these material goods, for the Europeans brought missions and schools as well as cargo.

Practically the only teaching the natives received about European life came from the missions, which emphasized the central significance of religion in European society. The Melanesians already believed that man's activities whether gardening, sailing canoes or bearing children-needed magical assistance. Ritual without human effort was not enough. But neither was human effort on its own. This outlook was reinforced by mission teaching.

The initial enthusiasm for European rule, however, was speedily dispelled. The rapid growth of the plantation economy removed the bulk of the able bodied men from the villages, leaving women, children and old men to carry on as best they could. The splendid vision of the equality of all Christians began to seem a pious deception in face of the realities of the color bar, the multiplicity of rival Christian missions and the open irreligion of many Whites.

For a long time the natives accepted the European mission as the means by which the "cargo" would eventually be made available to them. But they found that acceptance of Christianity did not bring the cargo any nearer. They grew disillusioned. The Astor now began to be put about that it was not the Whites who made the cargo, but the dead ancestors. To people completely ignorant of factory production, this made good sense. White men did not work; they merely wrote secret signs on scraps of paper, for which they were given shiploads of goods. On the other hand, the Melanesians labored week after week for pitiful wages. Plainly the goods must be made for Melanesians somewhere, perhaps in the Land of the Dead. The Whites, who possessed the secret of the cargo, were intercepting it and keeping it from the hands of the islanders, to whom it was really consigned. In the Madang district of New Guinea, after some 40 years' experience of the missions, the natives went in a body one day with a petition demanding that the cargo secret should now be revealed to them, for they had been very patient.

So strong is this belief in the existence of a "secret" that the cargo cults generally contain some ritual in imitation of the mysterious European customs which are held to be the clue to the white man's extraordinary power over goods and men. The believers sit around tables with bottles of flowers in front of them, dressed in European clothes, waiting for the cargo ship or airplane to materialize; other cultists feature magic pieces of paper and cabalistic writing. Many of them deliberately turn their backs on the past by destroying secret ritual objects, or exposing them to the gaze of uninitiated youths and women, for whom formerly even a glimpse of the sacred objects would have meant the severest penalties, even death. The belief that they were the chosen people is further reinforced by their reading of the Bible, for the lives and customs of the people in the Old Testament resemble their own lives rather than those of the Europeans. In the New Testament they find the Apocalypse, with its prophecies of destruction and resurrection, particularly attractive.

Missions that stress the imminence of the Second Coming, like those of the Seventh Day Adventists, are often accused of stimulating millenarian cults among the islanders. In reality, however, the leanest themselves rework the doctrines the missionaries teach them, selecting from the Bible what they themselves find particularly congenial in it. Such movements have occurred in areas where missions of quite different types have been dominant, from Roman Catholic to Seventh Day Adventist. The reasons for the emergence of these cults, of course, lie far deeper in the life-experience of the people.

The economy of most of the islands is very backward. Native agriculture produces little for the world market, and even the European plantations and mines export only a few primary products and raw materials: copra, rubber, gold. Melanesians are quite unable to understand why copra, for example, fetches 30 pounds sterling per ton one month and but 5 pounds a few months later. With no notion of the workings of world-commodity markets, the natives see only the sudden closing of plantations, reduced wages and unemployment, and are inclined to attribute their insecurity to the whim or evil in the nature of individual planters.

Such shocks have not been confined to the economic order. Governments, too, have come and gone, especially during the two world wars: German, Dutch, British and French administrations melted overnight. Then came the Japanese, only to be ousted in turn largely by the previously unknown Americans. And among these Americans the Melanesians saw Negroes like themselves, living lives of luxury on equal terms with white G.I.s. The sight of these Negroes seemed like a fulfillment of the old prophecies to many cargo cult leaders. Nor must we forget the sheer scale of this invasion. Around a million U. S. troops passed through the Admiralty Islands, completely swamping the inhabitants. It was a world of meaningless and chaotic changes, in which anything was possible. New ideas were imported and given local twists. Thus in the Loyalty Islands people expected the French Communist Party to bring the millennium. There is no real evidence, however, of any Communist influence in these movements, despite the rather hysterical belief among Solomon Island planters that the name of the local "Masinga Rule" movement was derived from the word "Marxian"! In reality the name comes from a Solomon Island tongue, and means 'brotherhood."

Europeans who have witnessed outbreaks inspired by the cargo cults are usually at a loss to understand what they behold. The islanders throwaway their money, break their most sacred taboos, abandon their gardens and destroy their precious livestock; they indulge in sexual license or, alternatively, rigidly separate men from women in huge communal establishments. Sometimes they spend days sitting gazing at the horizon for a glimpse of the long-awaited ship or airplane; sometimes they dance, pray and sing in mass congregations, becoming possessed and "speaking with tongues ."

Observers have not hesitated to use such words as "madness," "mania," and "irrationality" to characterize the cults. But the cults reflect quite logical and rational attempts to make sense out of a social order that appears senseless and chaotic. Given the ignorance of the Melanesians about the wider European society, its economic organization and its highly developed technology, their reactions form a consistent and understandable pattern. They wrap up all their yearning and hope in an amalgam that combines the best counsel they can find in Christianity and their native belief. If the world is soon to end, gardening or fishing is unnecessary; everything will be provided. If the Melanesians are to be part of a much wider order, the taboos that prescribe their social conduct must now be lifted or broken in a newly prescribed way.

Of course the cargo never comes. The cults nonetheless live on. If the millennium does not arrive on schedule, then perhaps there is some failure in the magic, some error in the ritual. New breakaway groups organize around "purer" faith and ritual. The cult rarely disappears, so long as the social situation which brings it into being persists.

At this point it should be observed that cults of this general kind are not peculiar to Melanesia. Men who feel themselves oppressed and deceived have always been ready to pour their hopes and fears, their aspirations and frustrations, into dreams of a millennium to come or of a golden age to return. All parts of the world have had their counterparts of the cargo cults, from the American Indian ghost dance to the communist-millenarist "reign of the saints" in Munster during the Reformation, from medieval European apocalyptic cults to African "witch-finding" movements and Chinese Buddhist heresies. In some situations men have been content to wait and pray; in others they have sought to hasten the day by using their strong right arms to do the Lord's work. And always the cults serve to bring together scattered groups, notably the peasants and urban plebeians of agrarian societies and the peoples of "stateless" societies where the cult unites separate (and often hostile) villages, clans and tribes into a wider religiopolitical unity.

Once the people begin to develop secular political organizations, however, the sects tend to lose their importance as vehicles of protest. They begin to relegate the Second Coming to the distant future or to the next world. In Melanesia ordinary political bodies, trade unions and native councils are becoming the normal media through which the islanders express their aspirations. In recent years continued economic prosperity and political stability have taken some of the edge off their despair. It now seems unlikely that any major movement along cargo-cult lines will recur in areas where the transition to secular politics has been made, even if the insecurity of prewar times returned. I would predict that the embryonic nationalism represented by cargo cults is likely in future to take forms familiar in the history of other countries that have moved from subsistence agriculture to participation in the world economy.
