8 8 THE AMERICAN SCIENCE SERIES. POLITICAL ECONOMY. By Francis A. Walker, President of the Massachusetts Institute of Technology. Advanced Course. 8vo. 537 pp. The peculiar merit of this book is its reality. The reader is brought to see the application of the laws of political economy to real facts. He learns the extent to which those laws hold good, and the manner in which they are applied. The subject is divided, as usual, into the three great branches of production, exchange, and distribution. An interesting and suggestive "book" on consumption is added, which serves to bring in con- veniently the principles of population. The last part of the volume is given to the consideration of various practical appli- cations of economic principles. From Richmond Mayo Smith, Professor in Columbia College, N. Y.: — In my opinion it is the best text-book of political economy that we as yet possess. From Woodrow Wilson, Professor in Princeton University, N. J.: — It serves better than any other book I know of as an introduction to the most modern point of view as to economical questions. Briefer Course. 12mo. 415 pp. The demand for a briefer manual by the same author for the use of schools in which only a short time can be given to the subject has led to the publication of the present volume. The work of abridgment has been effected mainly through excision, although some structural changes have been made, notably in the parts relating to distribution and consumption. From Alexander Johnston, late Professor in Princeton Univer- sity, N.J.: — Using the "Briefer Course" as a text-book, suited to any capacity, lam able at the same time to recommend the "Ad- vanced Course " to those who are better able to use it as a book of reference, or more inclined to carry their work further. Elementary Course. l2mo. 323 pp. What has been attempted is a clear arrangement of topics ; a simple, direct, and forcible presentation of the questions raised; the avoidance, as far as possible, of certain metaphys- ical distinctions which the author has found perplexing ; a fre- quent repetition of cardinal doctrines, and especially a liberal use of concrete illustrations, drawn from facts of common ex- perience or observation.
