Hinduism with all its rigidity is, it is true, sufficiently elastic to sanction, at least tacitly, a slow process of evolution by which the Panchama castes--for there are many castes even amongst the "untouchables"--gradually shake off to some extent the slough of "uncleanness" and establish some sort of ill-defined relations even with Brahmanism. For whilst there is on the one hand a slowly ascending scale by which the Panchamas may ultimately hope to smuggle themselves in amongst the inferior Sudras, the lowest of the four "clean" castes, so there is a descending scale by which Brahmans, under the pressure of poverty or disrepute, sink to so low a place in Brahmanism that they are willing to lend their ministrations, at a price, to the more prosperous of the Panchamas and help them on their way to a higher _status_. Thus probably half the Sudras of the present day were at some more or less remote period Panchamas. Again, during periods of great civil commotion, as in the 18th century, when brute force was supreme, not a few Panchamas, especially low-caste Mahrattas, made their way to the front as soldiers of fortune, and even carved out kingdoms to themselves at the point of the sword. Orthodox Hinduism bowed in such cases to the accomplished fact, just as it has acquiesced in later years when education and the equality of treatment brought by British rule have enabled a small number of Panchamas to qualify for employment under Government. But these exceptions are so rare and the evolutionary process is so infinitely slow and laborious that they do not visibly affect the yawning gulf between the "clean" higher-caste Hindu and the "unclean" Panchama. The latter may have learned to do _puja_ to Shiva or Kali or other members of the Hindu Pantheon, but he is not allowed within the precincts of their sanctuaries and has to worship from afar. Nor are the disabilities of the Panchama merely spiritual. In many villages he has to live entirely apart. He is not even allowed to draw water from the village well, lest he should "pollute" it by his touch, and where there is no second well for the "untouchables," the hardship is cruel, especially in seasons of drought when casual water dries up. In every circumstance of his life the vileness of his lot is brought home to the wretched pariah by an elaborate and relentless system of social oppression. I will only quote one or two instances which have come within my own observation. The respective distances beyond which Panchamas must not approach a Brahman lest they "pollute" him differ according to their degree of uncleanness. Though they have been laid down with great precision, it is growing more and more difficult to enforce them with the increasing promiscuity of railway and street-car intercourse, but in more remote parts of India, and especially in the south, the old rules are still often observed. In Cochin a few years ago I was crossing a bridge, and just in front of me walked a
