In 1908 Sir Bampfylde Fuller, then Chief Commissioner of Amman, proposed and the Government of India sanctioned, the preparation of a series of monographs on the more important tribes and castes of the Province, of which this volume is the first. They were to be undertaken by writers who had special and intimate experience of the races to be described, the accounts of earlier observers being at the same time studied and incorporated; a uniform scheme of treatment was laid down which was to be adhered to in each monograph, and certain limits of size were prescribed.
