¹ Bowman, Isaiah, The New World: Problems in Political Geography (Chicago, 1921, 4th ed., 1928Google Scholar). Dr. Bowman was chief territorial adviser and executive officer of the Section of Territorial, Economic, and Political Intelligence.

² In the most detailed of these, Bowman, Isaiah, Geography in Relation to the Social Sciences (Part V of the Rept., Comm. on Soc. Stud., Amer. Hist. Assoc., New York, 1934), political geography is discussed in ten pages (pp. 205–215)Google Scholar, with almost no bibliography. In Sauer's, Carl chapter on “Cultural Geography” in Recent Developments in the Social Sciences (Phila. and London, 1927), three pages are devoted to this branch of the field (pp. 207–210)Google Scholar, chiefly criticisms, in part justified but based on an evidently very limited survey. In Brunhes', Jean chapter on “Human Geography” in History and Prospects of the Social Sciences (H. E. Barnes, ed., New York, 1925), the discussion of political geography, pp. 71–74, 101–102Google Scholar, is limited almost entirely to a consideration of one book, that of Brunhes and Vallaux. (Cf. Sauer's comments on Brunhes' treatment of his subject). In the Encyclopedia of the Social Sciences, political geography appears only in a short paragraph under “Political Science” in which only Ratzel and Kjellén are mentioned. (For contrast, see “Politische Geographie” in the Staatslexicon, or the Politisches Handwörterbuch.)

³ A small exception is offered in the utilization of recent work of German students on the geography of political boundaries, in my “Geographic and Political Boundaries in Upper Silesia,” Annals Assoc. Amer. Geog., Dec., 1933, pp. 195–228Google Scholar.

⁴ That the Germans should be particularly interested in the subject since the War is obvious, but they have always shown more interest in it than has any other group. The environmental reasons for this, as well as for the lack of interest in this country, are discussed by Whittlesey, Derwent in “Environment and the Student of Human Geography,” Scientific Monthly, 1932, pp. 265–267Google Scholar.

⁵ The references in the footnotes provide a considerable up-to-date bibliography, not readily available elsewhere. The largest bibliography, including references to over 700 writers and fairly complete through 1924, is given in the footnotes of Maull, Otto, Polilische Geographie (Berlin, 1925), especially pp. 703–710Google Scholar. Bowman, , The New World, pp. 747–775Google Scholar, presents also a very large bibliography of a different sort, consisting chiefly of references to materials in economic geography, history, politics, etc., of value for the study of different countries. The writer regrets that he is limited to the literature in English, French, and German. In none of the bibliographies studied are there more than one or two important titles in any other modern language, though Haushofer speaks, in passing, of “prominent students of Geopolitik in Fascist Italy.”

⁶ For a detailed discussion of the development of political geography, see Maull, op. cit., pp. 1–30.

⁷ In his discussion of geography, Immanuel Kant provides for a political geography “founded entirely on physical geography.” “Kant's Physiche Geographie,” Philos. Bibl., B.A. 51, 2 Aufl. (Leipzig, 1904), p. 17Google Scholar (after Maull).

⁸ At least one of these hypotheses is of special interest in comparison with certain current theories. The Arab historian, Ibn Chaldun, held that the fourth temperature zone, of the seven zones of the Arab geographers, was the most favorable for civilization, as shown by the lands included in it—those of the Arabs, Romans, Persians, Jews, Greeks, Hindus, and Chinese. Maull, op. cit., p. 8.

⁹ Two non-geographers, a French historian, Febvre, and an American sociologist, Franklin Thomas, have made excellent detailed studies of the development of thought in this field, though Febvre's study was in fact written about 1914 and Thomas was not acquainted with the recent work in Germany. Both writers give somewhat exaggerated impressions of the importance of this aspect of geography in the general field, since neither is familiar with more recent developments.

¹⁰ The dates are those of the first publications of the respective writers in this field. Titles of these and a number of similar works may be found in the bibliography in Thomas, op. cit., pp. 317–329.

F., Boston, 1933)Google Scholar. Mackinder enlarged upon his earlier papers, notably “The Geographical Pivot of History” (Geog.

²¹ Nevertheless, Haushofer feels that the subject, as developed by Ratzel, Vallaux, and Mackinder, did have a notable influence on political thought and action in England and France—in the latter through the École de Politique—but unfortunately little or none in Germany. “Politische Erdkunde und Geopolitik,” in Freie Wege Vergleichender Erdkunde (Festgabe E. v.

²⁶ In addition, the following were engaged in cartographic work or prepared other special materials: de Margerie and Gallois (France), Marinelli and Ricchieri (Italy), and Jefferson, Lobeck, and Martin (United States). Sieger, who alone of the list had been an active student of political geography, came to Paris with the Austrian delegation, but had, of course, no opportunity to take part in the work of the Conference. Likewise the material which Teleki sent from Hungary had little effect; he was for a short period prime minister of Hungary. The above list, prepared chiefly from correspondence with several of the Americans mentioned, is probably not complete.

³⁴ Formerly a regular officer of the German army, Haushofer's intention to transfer to academic life was postponed by the War to 1920, when he retired as a majorgeneral. Now professor at the University of Munich, his best work is on Japan, where he was stationed as military attaché in 1908–11.

³⁶ In addition to the work of Ratzel and Kjellén, Haushofer lays particular emphasis on Fairgrieve's study, op. cit., which he has had published in German (trans. by Martha Haushofer, his wife) with an introduction by himself: Fairgrieve, J., Geographie und Weltmacht, eine Einleitung in die Geopolitik (Berlin, 1925)Google Scholar.

³⁷ Of the original group, Obst and Maull, formerly co-editors with Haushofer of the Zeitschrift, seem to have dropped out. Most prominent now are Lautenach, Albrecht Haushofer (son), and Baumann.

³⁸ It is perhaps significant that Kurt Vowinckel, who is not only the publisher of the Zeitschrift für Geopolitik and nearly all the separate publications in Geopolitik, but is in a sense editor (Schriftleiter) of the periodical, is now the appointed head of the publishers' association of Germany. Haushofer, formerly honorary professor at the University of Munich, was in 1933 appointed a regular full (ordinarius) professor.

⁴² A number of American geologists have made important studies of problems concerned with the control and production of mineral resources, which are, in part at least, based on economic geography. These include books and articles, chiefly in Foreign Affairs, by Bain, Leith, Spur, and George Otis Smith. A large number are listed in Whitbeck, R. H. and Thomas, O. J., The Geographic Factor (New York, 1932), pp. 189–190, 207–209, 231–233Google Scholar.

Bowman, Geography in Relation to the Social Sciences, Chap. 1; and “Geography” in Encyclopedia of the Social Sciences, Vol. 6, pp. 621 ff.Google Scholar, sections by Sauer, Vallaux, and Sapper. Brunhes' chapter in History and Prospects of the Social Sciences contributes little beyond a detailed discussion of the points of view of Ratzel and Brunhes.

⁴⁴ The two great critical studies of this type of geographic work, by Febvre and Thomas, have already been mentioned. Since those were published, there has appeared a significant successor to Miss Semple's great study which is much more moderate in its estimate of the importance of “geographic influences,” i.e., Whitbeck, Ray H. and Thomas, Olive J., The Geographic Factor; Its Rôle in Life and Civilization (New York, 1932)Google Scholar. This book is particularly valuable as a resumé of the work in English and American geography of the last quarter-century.

⁵⁸ Sauer classifies Herbertson simply as “an environmentalist” on the basis, apparently, of his Man and His Work (1899); but surely his later concept of “natural regions” is chorographic, and two of his students, using his notes, have prepared the first chorographic text-book in English on Europe: MacMunn, Nora E. and Coster, G., Europe; A Regional Geography (Oxford, 1924)Google Scholar.
