mass of detail, and the whole interpretation stands as a monumental 

 work in the young science of physiography. 



The complexity of structure, the varying altitudes, the differential 

 erosion, and the glacial interference have given many beautiful exam- 

 ples of readjusted drainage, some cases of which, e.g., the Raritan and 

 the Passaic, deserve to become classic. 



The chief changes in postglacial time have been in the way of 

 some readjustments of drainage in the drift, the beach action along the 

 coast, and the building of dunes. 



The whole of Part II, pp. 65-170 will be found a very valuable 

 help to the teacher of physiography, and, for these pages alone, should 

 be in every teacher's library. No plainer general statement of river 

 action can be found than is here given (pp. 70-79). 



The book is generously provided with maps of fine quality, with 

 diagrams and sections, and with exceptionally clear half-tone insets of 

 characteristic landscapes, all of which add very materially to the value 

 of the work. 



In the Appendix is collected a large mass of data, tables of geo- 

 graphical positions, of beachmarks, areas of drainage basins, forest 

 areas, and tide tables. An account of the nationality and distribution 

 of the population, and a statement of work accomplished in the mag- 

 netic survey closes the volume.
