 PLEISTOCENE GEOLOGY 



OF PORTIONS OF 



NASSAU COUNTY AND BOROUGH OF QUEENS 



PEEFACE 



The foUowing report by Prof. Woodworth on the results of field 

 work ill western Long Island is in continuation of an investiga- 

 tion of the quaternary formations of Long Island and the Quater- 

 nary history of the Hudson river valley begun in 1883 by the 

 present state geologist. 



The great development of the branch of Quaternarj^ investigation 

 makes it now possible to seek positive proof where formerly only 

 broad inferences could be drawn. 



Prof. Woodworth's work will include the Hudson and Cham- 

 plain valleys and the drainage basins tributary to them and his 

 results may be expected to contribute an important chapter to 

 American Quaternary history.
