_The Birds of Indiana_, by _Amos W. Butler_, lately published as part of Willis S. Blatchley's Twenty-second Annual Report on the Geology and Natural Resources of Indiana, is just at hand. It is one of the most accurate, detailed, and satisfactory local catalogues yet published. Three hundred and twenty-one species of birds have been taken in Indiana, and of each of these is given a detailed description, with a general account of its habits, song, migration, and nesting. In the case of the more rare species, full records of the dates and places of capture of the known specimens are appended. Analytical keys to genera and species are also given, so that every facility is furnished for the identification of species. This book is a model of its kind, and is a worthy fruit of Mr. Butler's twenty years of devoted study of the birds of his native State. _Robert H. Whitten_, in his monograph on _Public Administration in Massachusetts_--the relation of central to local activity--pursues a parallel course with that taken by Mr. John A. Fairlie in a similar essay on the Centralization of Administration in New York State, of this same series of Columbia University studies in History, Economics, and Public Law. Having found the systems and tendencies of administration in the early settlement of Massachusetts all for expansion and decentralization, Mr. Whitten now perceives the course altogether changed, and centralization more and more the rule. The change corresponds with changes in the conditions of life, and keeps track with them step by step. Of great dynamic forces which have been set to work and are bringing about a complete reconstruction of the social structure, improvements in transportation and communication were the most vital--first, turnpikes, then the steamboat, railroad, and telegraph; then the horse railway, cheap postage, the telephone, the electric railway, and the bicycle. The tendency at first was to bring about a concentration which was attended by the congestion of population in cities and the depopulation of the rural towns. "The electric railway, the telephone, and the bicycle came in to counteract these evils; while their tendency is strongly toward the centralization of bureaus, it is also toward the diffusion of habitations. These great socializing forces, going hand in hand with the development of the factory system and improvement of machinery, make possible a vastly higher organization of society than was possible under a stagecoach _régime_."
