THIS volume, which contains a great deal of original research work, is a valuable contribution to the practical side of the science of geography. It furnishes the teacher of the subject with a representative collection of practical exercises on the essential principles usually included in a four years' course of geography in an average secondary school. The 104 pages of part i. contain what may be regarded as a minimum course of practical geography. Part ii. (50 pages) is devoted to supplementary exercises which may be worked in the geography lessons or in the periods assigned to arithmetic, mathematics, physics, handwork, and drawing. The remainder of the book deals with outdoor work and advanced map-reading, revision exercises, etc. The work is skilfully planned, there being varied exercises for the beginner as well as for the advanced student. The principle of contour lines leads to isotherms, isobars, isohyets, etc. The diagrams showing isopleths for Java and Kew are particularly instructive.
