When I had the honour of addressing this Society a year ago, I spoke to it of our past history and hinted that I might at some future time have something to say about our present work and our future prospects. I do not wish to-day to grapple with the whole of such large subjects, but there are special reasons why I should as soon as possible call your attention to some particular aspects of them. My motives are largely practical. A movement has been maturing for some time which has for its object the promotion of international co-operation in historical work. During the last year it has reached the definite stage of creating a permanent international organisation of historical scholars for the promotion of co-operative undertakings on a large scale. It is an important movement and one which historians should have greatly to heart. It has attracted very little attention in this country and there is a danger lest we should not take our full share in the work in which we are now invited to play a part. I wish to give to it all the publicity that I am able, and to make an appeal to serious historians to do what they can to help it forward.
