Of closer personal and scholarly interest to Professor Paxson is the subject of the growth and development of the Rocky Mountain States: Far-Western railway-building, mining, cattle-raising, and the establishment of government agencies for the conservation of the national resources. While the older and dangerous sectionalism seems to be forever past, the special interests of the Far West, as shown in this work, still lend color to a new sectionalism which sometimes threatens the old political party habits; witness the contest of 1908-12 and the troubles between California and Japan. And here Professor Paxson challenges attention by his treatment of the results of the Spanish-American War, the imperialism which brought to the United States the control of the Philippines, and made the isolated and somewhat provincial country of Blaine and Cleveland a world-power, with interests in the Pacific and a potential voice in the final destiny of China. Such have been the problems and the aims of the writers of these four short volumes. In order to visualize the main topics discussed, resort has been made to the making of maps, simple drawings intended to show at the different crises just where, or how important, were the decisive factors. This is a feature which, it is thought, will please both lay and professional readers. Certainly the making of these maps was no small part of the work of each author, and in most instances they are entirely original and made from data not hitherto used in this way; for example, the drawings which show just what sections of the States the various candidates for the Presidency "carried." The same may be said of those which treat of the cotton, tobacco, and industrial areas of the United States. Although there may be faults and errors in the work, it seems to the Editor that, on the whole, the story of the beginnings, the growth, and the present greatness of the country, as set forth in these volumes, is both interesting and suggestive, that the real forces have been duly emphasized, and that at many points contributions to historical knowledge have been made.
