PREFACE THE history of ¢ The Old Empire from the Beginnings to 1783 * has been told at length in the first volume of ‘ The Cambridge History of the British Empire,’ which was published last year. I had the honour of writing a few Introductory pages to this comprehen- sive work, in which, under most able editors, experts on various times and subjects have collaborated with great effect. Possibly it was this connexion which set me thinking what were the main driving forces in the Old Empire as compared with later times. The result of plentiful references to standard writers and of some tesearch is given in this little book. 1930, C. P. LUCAS.
