make itself endogamous. If a group desires to make itself endogamous a formal injunction against intermarriage with outside groups will be of no avail, especially if prior to the introduction of endogamy, exogamy had been the rule in all matrimonial relations. Again, there is a tendency in all groups lying in close contact with one another to assimilate and amalgamate, and thus consolidate into a homogeneous society. If this tendency is to be strongly counteracted in the interest of Caste formation, it is absolutely necessary to circumscribe a circle outside which people should not contract marriages.
Nevertheless, this encircling to prevent marriages from without creates problems from within which are not very easy of solution. Roughly speaking, in a normal group the two sexes are more or less evenly distributed, and generally speaking there is an equality between those of the same age. The equality is, however, never quite realized in actual societies. At the same time to the group that is desirous of making itself into a caste the maintenance of equality between the sexes becomes the ultimate goal, for without it. endogamy can no longer subsist. In other words, if endogamy is to be preserved conjugal rights from within have to be provided for, otherwise members of the group will be driven out of the circle to take care of themselves in any way they can. But in order that the conjugal rights be provided for from within, it is absolutely necessary to maintain a numerical equality between the marriageable units of the two sexes within the group desirous of making itself into a Caste. It is only through the maintenance of such an equality that the necessary endogamy of the group can be kept intact, and a very large disparity is sure to break it.
The problem of Caste, then, ultimately resolves itself into one of repairing the disparity between the marriageable units of the two sexes within it. Left to nature, the much needed parity between the units can be realized only when a couple dies simultaneously. But this is a rare contingency. The husband may die before the wife and create a surplus woman, who must be disposed of, else through intermarriage she will violate the endogamy of the group. In like manner the husband may survive his wife and be surplus man, whom the group, while it may sympathise with him for the sad bereavement, has to dispose of, else he will marry outside the Caste and will break the endogamy. Thus both the surplus man and the surplus woman constitute a menace to the Caste if not taken care of, for not finding suitable partners inside their prescribed circle (and left to themselves they cannot find any, for if the matter be not regulated there can only be just enough pairs to go round) very likely they will transgress the boundary, marry outside and import offspring that is foreign to the Caste.
Let us see what our imaginary group is likely to do with this surplus man and surplus woman. We will first take up the case of the surplus woman.
