higher, are grandfathers and grandmothers; below, are sons and daughters and the grandsons and granddaughters. The same, of course, holds also for women. Thus, the system as a whole comprises five generations.

Now, it was maintained that this system could have arisen only out of a previous condition of general promiscuity. For, unless the actual father were universally unknown, how could it be possible that a person would call by the name of father every man within the same kinship group who might, as regards age, be his father? If, however, we propose this argument, we immediately strike a weak point in the hypothesis, since all women of the older generation are called mother just as its men are called father. We should certainly expect that the real mother would be known, because the child derives its nourishment from her during a period which is especially long among primitive peoples, and because it grows up close to her. And, furthermore, the hypothesis is hardly reconcilable with the fact that, for the most part, Malayo-Polynesian languages differentiate relations by marriage even more sharply than do our own. An Hawaiian man, for example, calls the brother of his wife by a different name than does a woman the brother of her husband. Thus, in place of our word 'brother-in-law' they have two expressions. In any event, the term 'brother-in-law' is applied to an individual, and therefore implies marriage. To meet this point, we would be obliged to fall back on the supposition that these terms represent later additions to the original nomenclature of relationship. But even then the fact would remain that, in their direct reference, these terms are merely names for differences in age. It therefore remains an open question whether the terms also designate relationship; to the extent of our observation, this is certainly not the case. The native of Hawaii, so far as we know anything about him, knew his father and mother: what he lacked was merely a specific name for them. Whenever he did not call his father by his given name, he evidently called him by the same name that he applied to the older men of his immediate group. Among European peoples also, the terms 'father' and 'mother' are sometimes used in connection with men and women outside this relationship. For example, the Russians, particularly, have a custom of addressing as 'little father' and 'little mother' persons who are not in the least related to them. That which makes it highly probable that in the so-called Malayan system of relationship we are dealing not with degrees of relationship but with age-periods, is, in the last event, a different phenomenon—one that has hitherto been overlooked in connection with these discussions. In the very regions whose languages employ this nomenclature, custom prescribes that the youths and men live in separation from the women and children from their earliest years on. This is the institution of the men's club with its age-groups. Its social rôle is an important one, crowding even the family association into the background. Under such circumstances, the individual is naturally interested first of all in his companions of the same age-group, for each of these usually occupies a separate apartment in the men's house. Thus, the so-called Malayan system of relationship is really not a system of relationship at all, but a nomenclature of age-groups based on social conditions. These conditions bring it about that companions of the same sex are more closely associated than are men and women. In the men's houses a companion of the same group is a brother, one of the next older group, a father. Together with these men the individual goes to war and to the hunt. Thus, these phenomena cannot be said to belong to the lowest stage of culture. Nor, obviously, does this terminology, which has reference to differences of age, exclude any particular form of marriage. In this case it is a mistake to associate the names 'father,' 'mother,' 'brother,' etc., with the concepts that we attach to these words.

The hypothesis that the family, whether of monogamous or of polygamous organization, was preceded by a state of unrestricted sexual intercourse, so-called agamy or promiscuity, is, however, as was remarked above, based not only on the fact of maternal descent and of the Malayo-Polynesian method of designating ages, but also on that of group-marriage. In this form of marriage, a number of men marry in common a number of women. This is interpreted as a transitional stage between an unrestricted sexual intercourse within the tribe and the limited marriage unions of later times. At first glance, indeed, this might appear probable. In order, however, to decide whether such a transition could take place, and how it might occur, we must first of all consider the relation which group-marriage sustains, among the peoples who practise it, to the other forms of marriage. It then appears at once that it is a particular form of polygamy. True, it is not identical with the form of polygamy most familiar to us, in which one man possesses several wives. But there is also a second form, which, though less frequent, is of greatest importance for an interpretation of group-marriage. One woman may have several husbands. The two forms of polygamy may conveniently be called polygyny and polyandry, and these terms should always be distinguished in any attempt at a precise account of polygamous marriage. Polygyny is very prevalent even in our day, occurring particularly in the Mohammedan world, but also among the heathen peoples of Africa, and in other regions as well. It was likewise practised by the ancient Israelites, and also by the Greeks, although the Indo-Germanic tribes for the most part adhered to monogamy from early times on. Polyandry is much less common, and is, indeed, to be found only among relatively primitive peoples. It occurs in Australia and, in the southern part of Hindustan, among the Dravidians, a tribe of people crowded back to the extreme end of the continent by peoples who migrated into India; it is found also far in the north among the Esquimos of Behring Strait and among the Tchuktchis and Ghilyaks of Siberia, and, finally, here and there in the South Sea Islands.

If, now, we wish to understand the relation of these two forms of polygamy to each other, we must first of all attempt to picture to ourselves the motives that underlie them, or, wherever the custom has become fixed through age, to bring to light the motives that were originally operative. In the case of polygamy, the immediate motive is evidently the sexual impulse of man which is more completely satisfied by the possession of several wives than by that of a single one. This motive, however, does not stand alone; as a rule other contributing circumstances are present. Two such important factors, in particular, are property rights and the power of authority. Polygyny flourishes particularly wherever the general conceptions of property and of authority, and, connected with the latter, that of the supremacy of man within the family, have attained undue importance. Under the co-operation of these motives, the wife becomes the absolute property of the husband, and may, therefore, wherever polygyny prevails among barbaric peoples, be given away or exchanged. Bound up with this, moreover, is the fact that, wherever there are considerable social differences, dependent on differences in property and rank, it is principally the wealthy or the aristocratic man who possesses many wives. In the realm of Islam, the common man is, as a rule, content with a single wife, so that monogamy here prevails in the lowest stratum of society.

With polyandry the case is essentially otherwise. In it, entirely different motives are operative; it might, indeed, be said that they are the exact opposite of those that bring about polygyny. It is particularly significant that polyandry is found in regions where there is a scarcity of women. This scarcity, however, is, in turn, generally due to an evil custom of barbaric culture, namely, infanticide. In Polynesia, where polyandry was very prevalent, this custom was at one time fairly rampant. Even to-day infanticide still appears to be practised by some of the Dravidian tribes of Hindustan. Similar conditions prevail among the Australians. In Polynesia, however, and probably in other localities as well, it was chiefly the female children who were the victims of infanticide. The natural result was a decrease in women and a striking numerical disproportion between the sexes. Thus, Ellis, one of the older English investigators of conditions in these territories, estimated the relation of men to women as about six to one. Under such circumstances the custom of polyandry is intelligible without further explanation. It was not possible for every one to possess a wife of his own, and so several men united to win one wife in common.

We might ask why it was chiefly girls who fell victims to this murder. That children in general should be sacrificed, under the rough conditions of nature, is not inexplicable. It is due to the struggle for the necessities of life and to the indolence that shrinks from the labour of raising children. The desire is to preserve the lives of only a limited number; the remainder are killed immediately after birth. In Polynesia, the murder was forbidden if the child had lived but a single hour. Occasionally, magical motives are operative, as in the case of the horror which the man of nature feels towards deviations from the normal and towards the birth of twins. That male children are more often spared than female, however, can scarcely be explained otherwise than on the ground that a particular value is placed on men. The man is a companion in sport and in the chase, and is regarded as more valuable for the further reason that he aids in tribal warfare. This higher value reverts back even to the child. It is evidenced also in the fact that, in the case of women, the arrival of adolescence is not celebrated with the same solemn ceremonies as are held in the case of young men. Whereas great celebrations are held when the youth reaches the age of manhood, little notice is taken, as a rule, of the maiden's entrance into womanhood. By means of these celebrations, the youths are received into the society of men, and, together with companions of their own age, are initiated into the traditional ceremonies. In these ceremonies women are not allowed to participate.

Though the causes of polyandry are thus entirely different from those of polygyny, it does not at all follow that these forms of marriage are mutually exclusive. On the contrary, they may very well exist side by side, as, indeed, they actually do in many places. But how, then, is so-called group-marriage related to these two forms? It is obviously nothing but a combination of polyandry and polygyny. In fact, whenever a group of men marries a group of women, these two forms of polygamy are both involved. Every man has several wives, and every wife has several husbands. Only, indeed, on the basis of a purely external and superficial consideration could one look upon polygyny and polyandry as unconjoinable, because they are, in a certain sense, opposing ideas. As a matter of fact, they do not really exclude each other. If we bear in mind the causes mentioned above, it is obvious that under certain conditions of life, such as occur particularly in a more primitive environment, their combination is more probable than their mutual exclusion. If, especially among tribes who have not yet developed sharply defined distinctions based on property and power, as, for example, among the Australians, every man strives to obtain several wives (which is the state of polygyny), while, on the other hand, there actually exists a dearth of women (which means that motives to polyandry are present), the two forms naturally combine with each other. This is frequently verified, moreover, whenever we are able to gain any degree of insight into the particular conditions surrounding the origin of such group-marriages, and also whenever their forms undergo a modification of details. Among Australian tribes, for example, particularly in the southern part of the continent, there is a common form of group-marriage, in which a man possesses either one or several chief wives, together with secondary wives; the latter are the chief wives of other men, whereas his own chief wife is in turn the secondary wife of those men or of others. This custom is very similar to what is probably the most common form of polygyny, namely, the possession by a man of only one chief wife in addition to several secondary wives,—a form of marriage that is obviously derived from monogamy. One agency that is particularly apt to bring about such a form of marriage, transitional between monogamy and polygyny, is war. We know from the Iliad that in barbaric times woman was the booty of the conqueror, and became his slave or secondary wife. So also, according to the Biblical legend, Abraham possessed a chief wife, Sarah, who belonged to his own tribe, but also a secondary wife, Hagar, who was an Egyptian slave. Wherever the concept of property became prominent, the purchase of women proved to be a further source of polygyny. In this case also, there was generally one chief wife, wherever polyandry did not interfere. When the Mohammedan of modern times calls his chief wife 'favourite,' it is merely another indication that this form of polygyny developed from monogamy, since, according to the old custom, there was but one chief wife. Here, however, the chief wife is no longer necessarily the wife belonging to a man's own tribe, as was the case among the ancient Israelites; the favour of the master determines which wife shall be given the privileged place.

Thus, from whatever angle we view group-marriage, its polygyny and its polyandry seem to rest on monogamy. This is true also of forms of group-marriage other than those mentioned above. Where the theft of women still continues to be a practice more serious than are the somewhat playful survivals that occur in the marriage ceremonies of cultural peoples, the one who wishes to steal a wife not infrequently secures confederates for his undertaking. Custom then commonly gives these companions a certain right to the stolen woman. This right, of course, is for the most part temporary, but it may nevertheless come to approximate the conditions of group-marriage in case the first man assists his confederates in the same way in which they have aided him. There is still another and a related motive that may lead to the same result. When a woman enters into marriage with a man of a certain tribe, she at once enters into very close relations with the tribe itself. Where tribal association has gained a preponderant importance, custom sometimes grants to all the male members of the tribe certain transient rights with respect to the woman on the occasion of her marriage. This occurs particularly when the man and woman belong to different tribes—that is, in the case of exogamy, an institution characteristic of the totemic age and to be considered later. For, the lively consciousness of kinship differences naturally tends to strengthen the right of appropriation belonging to the entire tribe. A similar thought is reflected in the mediæval jus primæ noctis of certain provinces of France and Scotland, except that in place of the right of the kinship group to the possession of the individual we here find the authority of the lord over his vassals.
