CHAMBERLIN, T. C., and SALISBURY, R. D. 



1904. Geology. Geologic Processes and their Results, Vol. 



I. pp. 654. New York. 



To be considered from the standpoint of the agents 

 and processes which change animal habitats and 

 result in their "orderly sequence." 



.VAN HISE, C. R. 



1904. A Treatise on Metamorphism. U. S. Geol. Survey, 



Monog., Vol. XLVH, pp. 1-1286. 

 A formidable-looking volume on account of its size, 

 but one which will abundantly repay a careful study 

 of its method, aside from the value of the content, for 

 problems related to animals of the soils, etc. Par- 

 ticular attention should be given to the formulation 

 of dynamic principles, and the application of the 

 process method. 



DAVIS, W. M. 



1909. Geographical Essays, pp. 777. New York. 



Essays on the orderly sequence of changing land forms, 

 or to the ecologist, the development of inland habi- 

 tats, in so far as they are dependent upon the 

 physiographic conditions. 



WOODWORTH, J. B. 



1894. The Relation between Baseleveling and Organic Evolu- 

 tion. Amer. Geol., Vol. XIV, pp. 209-235. 

 The influence of baseleveling factors in the develop- 

 ment of the gross environment and upon evolu- 

 tion. 



ADAMS, CHAS. C. 



1901. Baseleveling and its Faunal Significance, with Illustra- 

 tions from Southeastern United States. Amer. 

 Nat., Vol. XXXV, pp. 839-852. 

 The influence of baseleveling upon the sequence of 

 changes in fresh-water and land habitats. (See
