THESE volumes correspond to the four subdivisions required by the College Entrance Examination Board, and by the New York State Education Department. Each volume is designed for one year's work. Each of the writers is a trained historical scholar, familiar with the conditions and needs of secondary schools.

The effort has been to deal only with the things which are typical and characteristic; to avoid names and details which have small significance, in order to deal more justly with the forces which have really directed and governed mankind. Especial attention is paid to social history, as well as to the movements of sovereigns and political leaders. The books are readable and teachable, and furnish brief but useful sets of bibliographies and suggestive questions. No pains have been spared by maps and pictures, to furnish a significant and thorough body of illustration, which shall make the narrative distinct, memorable, and clear.

Commercial Geography

By HENRY GANNETT, Geographer of the United States Geological Survey and the Twelfth Census; CARL L. GARRISON, Principal of the Morgan School, Washington, D. C. ; and EDWIN J. HOUSTON, A. M., Ph.D. (Princeton), Emeritus Professor of Physical Geography and Physics, Central High School, Philadelphia.

IN this book commercial geography is presented in a simple, methodical, and logical way, to the end that its study shall be not only informative, but truly educative and worth while. The treatment is divided into three parts: Commercial Conditions ; Commercial Products; and Commercial Countries. The first portion gives a clear, brief statement of the physical, social, and economic conditions that largely influence commerce in every region. The second part treats of the cultivation of the soil, and of the vegetable, animal, and mineral products that enter commerce. The great commercial staples are taken up separately, and their production, manufacture, and use described. Diagrammatic maps and graphic diagrams are presented, showing where each staple is produced, and the percentage of the world's product supplied by each of the chief contributing countries. The final and largest division is devoted to a careful description of each of the countries of the earth with special reference to its industries and commerce. Maps of the countries indicate the location of the chief industrial centers, the trade routes, and the production areas. Diagrams or tables of imports and exports, etc., are also numerous. The present condition of the world's commerce is carefully and accurately portrayed. In the text figures of absolute quantities and values have been largely avoided, because it is the relative rather than the absolute quantities that the pupil should remember. Hence the products of countries are usually given in percentages of the world's total. Absolute quantities can easily be deduced by comparing these percentages with the tables at the close of the book.
