The Eclectic Fhysical Geograpliy 



DIFFERS WIDELY FROM THOSE IN GENERAL USE. 



1. The Charts are distinct and graphically accurate. Each chart presents but a single set of 



physical features. 



2. No scientific knowledge on the part of the young student is assumed. 



3. The order of treatment is natural and logical. 



4. Phenomena are not simply described, but are traced to proximate causes. 



5. The treatment of Erosion is not dismissed with the usual brief paragraph. Nearly every 



chapter finds in erosion a cause or an effect. 



6. It discards the theory that the secular cooling and contraction of the planet is the main 



cause of the present relief of the globe. 



7. The chapters on Life, and on IVeat/icr and Climate, are full and in conformity to modern 



science. 

 The scientific accuracy of the book is attested by eyninent specialists.
