(1) What Sir H. Risley calls _the tribal type_, instances of which have been given above. Such tribal castes abound in all parts of India. It is not improbable that the great Sūdra division of Hindu tradition was originally the whole mass of Dravidian aboriginals as they came into contact with Aryan immigrants, and were conceded a subordinate place in their social system. It would be useless to give a list of the names of such castes, but I cannot refrain from mentioning the excellent Doms of the Assam Valley, whose name unfortunately associates them with very different people in India proper. They are obviously of Tibeto-Burman origin, and deserve closer study than they receive. Their long thatched places of worship, true synagogues for meeting together and curiously unlike the tiny _cellæ_ of Hindu temples, are among the most conspicuous features of Assam villages. They have no idols, and place a _puthi_, a holy book, on what may pass for the village altar. They are vaguely Hinduised, but will humbly declare "_āmi hindu na hô_," "we are not Hindu folk." Yet they are well on their way towards acceptance into caste, and have already a strong infusion of Hindu blood. Other border races, though they are still too savage and independent to become Hindu, are marked down for absorption. Such, for instance, are the Daflas of the northern border of Assam, cousins of the Abors to whom attention has been drawn by recent events. The Daflas are still frankly animistic; their love of strong spirits and other intoxicants, their addiction to their favourite diet of roast pork, their extremely uncleanly habits and barbarous speech, all make them very offensive to the gentle vegetarian Hindus their neighbours. But it happens that the tribal costume closely resembles the traditional dress of Mahādēva, the Destroyer, the most active and formidable member of the Hindu Trinity, and already some Hindus speak of these genial Highlanders as Siva-bansa, as "of Siva's race." Many other examples, with interesting details of fictional methods, will be found in Mr E. A. Gait's admirable _History of Assam_.
