"All talk on modern poetry, by people who know," wrote Mr. Carl Sandburg in Poetry, "ends with dragging in Ezra Pound somewhere. He may be named only to be cursed as wanton and mocker, poseur, trifler and vagrant. Or he may be classed as filling a niche today like that of Keats in a preceding epoch. The point is, he will be mentioned."This is a simple statement of fact. But though Mr. Pound is well known, even having been the victim of interviews for Sunday papers, it does not follow that his work is thoroughly known.
