mentary book than the Geography, whereas the present practice in 

 high schools, one recommended by the Conference on Geography 

 appointed by the Committee of Ten, is to place physical geography 

 in the earlier part of the curriculum and geology, when studied at 

 all, near the end. For these reasons, and because of the size of the 

 two books, it is questionable whether they will ever be widely used 

 together. Where such use is attempted, considerable culling and dove- 

 tailing will be necessary. This would be easier for the teacher if the 

 paragraphs were numbered. But doubt as to the feasibility of the 

 author's plan does not mean condemnation of the book as a whole. 

 It is admirably adapted for high-school pupils, and it is to be hoped 

 that it will be widely used. 



There is so much that is to be commended in it that it is to be 

 regretted that a few slips have passed uncorrected. On page ii8 the 

 language implies that the term "oxidation" embraces all the chemical 

 changes caused by percolating water; and the expression " limy shells " 

 (p. 132) as applied to corals is hardly accurate. The statements in 

 the text concerning normal and reversed faults (pp. 293, 324) do not 

 correspond with the diagrams (p. 292) and the following sentence, 

 " Mountains are present in nearly all parts of the world " (p. 314) 

 does not agree well with another statement that " the formation of 

 mountains occurs in only a few comparatively small parts of the whole 

 earth" (p. 328). It may seem hypercritical to refer to some of 

 these points, but too much care cannot be taken in a text-book to be 

 used by immature pupils, and perhaps by teachers, who have not a 

 wide knowledge of the subject. But these are not vital and do not 

 detract greatly from the value of the book. Professor Tarr can be con- 

 gratulated upon the degree of merit to which the book has attained.
