My thanks are due to the Government of India for permission to use illustrations contained in official publications. Except where otherwise stated the numerous maps included in the volume are derived from this source. My obligations to provincial and district gazetteers have been endless. Sir Thomas Holdich kindly allowed me to reproduce some of the charts in his excellent book on India. The accuracy of the sections on geology and coins may be relied on, as they were written by masters of these subjects, Sir Thomas Holland and Mr R. B. Whitehead, I.C.S. Chapter XVII could not have been written at all without the help afforded by Mr Vincent Smith's Early History of India. I have acknowledged my debts to other friends in the "List of Illustrations."
