The chief abode of the races that form the subject matter of this study has been the centre of the peninsula, namely, the Vindhya mountains which run east and west, from the Ganges to Gujarat, and the broad forest tract extending notrh and south from the neighbourhood of Allahabad to the banks of the river Godavari; but they might not necessarily be the aborigines of the places they have occupied in recent times.
In the Vedas the `Dasyas`, whose descendants the members of the tribes studied are spoken of as having given a great deal of trouble to the Brahmins; and they were apparently pushed into their recent homes by successive tides of invaders operating against them, and often appear as if they were cut off into small parties in their flight, portions of the same race being found scattered in different corners of the country.
The main divisions of the `Dasyas` as classified by the author are: the Gonds, the Bheels, the Kolis, the Mairs and Meenas, the Khonds, the Koles, and the Sonthals; but they are not one people. Some particular features they do share in common. But the dissimilarities between them are also great in several respects.
