of Yale University comes along with two great volumes, and a promised third, in which he approaches world history with an even larger canvas and larger brush. He tells us himself that he is presenting us with "a new synthesis of modern history." We confess to as profound a distrust of the word "synthesis" as some people have of the word "definitive," and when a professor tells us that he has produced a new synthesis of history we are inclined to believe that this is another way of admitting that Providence has not granted him the gift of clear thinking or clear writing. But Professor Abbott's preface does him and his book an injustice. Some doctors, if you go to them with a swollen arm, will tell you that you have œdema of the arm; but there is no need to be frightened--the doctor is only telling you, what you know already, that you have a swollen arm. So, too, there is really no need to be frightened by the historian who assures you that his book has a synthesis; he probably only means, what you know already, that his book has a subject. We have not discovered the synthesis in Mr. Abbott's 1000 pages, but we have discovered that he has a very good subject and has written, in many respects, a very good book. The book itself proves that he is well equipped with knowledge and has made full use of the intensive and microscopic study of the modern historian. But he approaches history from the standpoint of enthusiastic and large-minded youth. He has thrown away his microscopes and determined to look back at history through a telescope. Immediately a large and dominating fact has attracted his attention. The age we live in is pre-eminently the European Age. The world is dominated by Europe and Europeans: there have in the past been eras in which a race or races have by migrations and conquests spread themselves and their civilisation and government over wide spaces of the earth, but never before has there been so universal and permanent a domination and expansion from one small quarter of the globe. Professor Abbott, seizing his historical telescope, has looked back and tried to discover the origin, the causes, and the courses of this amazing phenomenon. And the more one investigates the phenomenon the more amazing it appears. Take the case of migrations. The European Age or the modern world, as Professor Abbott has no difficulty in showing, began in the fifteenth century. (In history, of course, there is really never any real beginning or any real end; there are no abrupt transitions, only faster or slower currents in the stream of change; nevertheless there are periods in which the movement quickens so perceptibly that they are clearly turning-points in human history; and the fifteenth century is undoubtedly such a turning-point.) Now one of the most striking facts in the modern world has been the migration of Europeans. In North America, Northern Asia, Australia, South Africa, and to some extent in
