supplement to this book. At the western extremity of the range of hills is another group, the Garos, of whom an excellent account has lately been published by Major A. Playfair, I.A. (London, David Nutt, 1909). The Garos are of peculiar interest as members of the Boḍo family, because they were head-hunters within the memory of men still living.

Finally in the range of hills in the south of the Surma Valley, there are the Tipperahs whose language is obviously a branch of the ancient Boḍo speech; quiet inoffensive people, ruled over by a semi-independent Raja who is also a great land-owner in the British districts of Tipperah and Sylhet.

Now, the anthropologists rightly caution us against rashly concluding that a common speech, where races are in contact, implies a common origin, since everywhere, and especially among people who use an unwritten language, nothing is more common than the borrowing of a neighbouring tongue. But where, as here, we have five absolutely separate communities of semi-savage people, who nowadays are not so much as aware of one another’s existence, and yet speak what is to all purposes the same language, it is plain that they must have been united at no very distant date by some common social bond. The date cannot have been very distant, because in the unwritten speech of semi-savage people phonetic decay acts very rapidly, and a very few years may serve to disguise the relationships of adjacent and cognate tongues. No one who has heard members of the five branches of the Boḍo race speak their respective languages can fail to recognise that they belong to the same linguistic group. Moreover, this common Boḍo speech was, till within a few years ago, the language of the Koches, the dominant and ruling tribe in the great Koch kingdom, which survived, with something of its ancient prestige and power, long enough to be visited by an Englishman, Ralph Fitch, in Queen Elizabeth’s time. It would seem, then, that the language spoken in the ancient Koch kingdom, which extended from the Himalayas to the Bay of Bengal, was the Koch or Boḍo language, and the mass of the people must have been of Boḍo origin. In the Brahmaputra valley these Boḍos have survived in the midst of Hindu and Shan invaders and settlers, of whom those who are interested in the subject may read in Mr. E. A. Gait’s admirable History of Assam, (Calcutta, Thacker, Spink and Co., 1906). Here the anthropologist may come to the rescue of the historian. The Boḍo type of face and physical construction is, as Mr. Endle says, of an Indo-Chinese kind, easily distinguishable from the Arya-Dravidian type common in adjacent Bengal, and careful measurements in the Brahmaputra and Surma Valleys ought to show how far the old Koch element still persists, how far it has been obliterated by inter-marriage with Indian immigrants.

It may, however, be assumed that the population of the Koch kingdom, and therefore of its predecessor, the famous classical empire of Kāma-rūpa, of which Sanskrit scholars may read in the Mahābhārata (perhaps in a late interpolation in the epic) was chiefly Boḍo, of the same type as the humble folk who are the subject of Mr. Endle’s book. Kāma-rūpa was visited in the first half of the seventh century of our era by the famous Chinese traveller Hiuen Tsiang, whose interesting account of the land and people may be found at page 22 of Mr. Gait’s History. “They adore and sacrifice,” says the Chinese explorer, “to the Devas and have no faith in Buddha.”

It was apparently in the kingdom of Kāma-rūpa that there came into being that form of Hinduism whose scriptures are the later Purāṇas and the Tantras, the worship of Śiva and his Sakti, that form of the Hindu cult which, to this day and even in the temple of Kāli-ghāṭ in Calcutta itself, is distinguished by sacrifice by
