But eloquence was not the main feature of his lectures, nor yet the quality he most desired in the recitations of his students. Woe betide the young man who had spent too little time upon the "constitutional period," and who tried to give this argus-eyed instructor the impression of deep and careful study. The bubble was sure to be pricked, and the discomfiture of the ambitious one was, while frequently laughable, always unmistakable. One never knew when he was going to be "quizzed" in "Freddie's" class. But one thing was certain: that was that he would be asked a question, and when that question came it was best, from every point of view, to be able to do good, clear, straight thinking, based on a fund of religiously acquired information. One quality that Professor Turner exacted of himself and others was that assertions must be backed up by evidence. Perhaps that is not the least important reason why the article from which a selection is here made created as profound a change in the general attitude toward American history as any single word on that subject that has ever been spoken. THE SIGNIFICANCE OF THE FRONTIER IN AMERICAN HISTORY From "THE ANNUAL REPORT OF THE AMERICAN HISTORICAL ASSOCIATION" for 1893, pp. 199-227. By Professor Frederick J. Turner, then of the University of Wisconsin. In a recent bulletin of the Superintendent of the Census for 1890 appear these significant words: "Up to and including 1880, the country had a frontier of settlement, but at present the unsettled area has been so broken into by isolated bodies of settlement that there can hardly be said to be a frontier line. In the discussion of its extent, its westward movement, etc., it cannot, therefore, any longer have a place in the census reports." This brief official statement marks the closing of a great historic movement. Up to our own day American history has been in a large degree the history of the colonization of the Great West. The existence of an area of free land, its continuous recession, and the advance of American settlement westward, explain American development.
