INTRODUCTORY STATEMENT.^ 



The plans for the investigation the resuks of which are here pre- 

 sented were first made under the direction of Professor R. D. Salis- 

 bury. At the beginning of the actual work, in the absence of Professor 

 Sahsbury from the country, the work was pursued under the direction 

 of Professor T. C. Chamberlin, and has been continued under his 

 direction up to the present time. The writer's interest in the subject 

 was first aroused while engaged in detailed mapping of the Pleistocene 

 deposits of the Palisade Ridge of eastern New Jersey in 1893 and 

 1894, under Professor Salisbury's direction.^ Subsequently, in the 

 preparation of the Pleistocene maps for the New York City Folio ^ 



1 A brief summary of this paper was presented before the Geographic Society of 

 Chicago in March, 1904. An alternative hypothesis bearing on crustal movement 

 entertained at that time has replaced one favored then.
