I Would like to preface what I have to say this evening by one deprecatory remark. I should not venture to tax your patience or reveal my own ignorance by attempting to speak of the Imperial Conference of 1926 as a whole. It was, probably, the most important of the striking series of Colonial and Imperial Conferences which have been held; and it covered an enormous area. It may be that the aspect of it with which alone I propose to deal is not the most important side of its many-sided labours, which included such matters as Inter-Imperial Trade. Defence, Air Communications, Nationality, Overseas Settlement, and Economic Resources. But it is the only one on which I am even moderately competent to speak; and therefore I beg to draw your attention to the fact that I am going to speak of the Imperial Conference only on its constitutional side.
