PREFACE. 



During the past five years the undersigned has had occasion 

 to examine critically the geological literature of Connecticut. 

 The list of papers read, and the notes made during these years, 

 are here presented, with the hope that they may be useful to 

 students interested in the subject. 



The list of titles is believed to be practically complete to 

 January, 1906, and a few papers of more recent date have been 

 added. Articles in the local newspapers, and descriptions in 

 text-books have been omitted. 



In preparing the notes an effort has been made wherever 

 practicable to give the author's main conclusions, instead of 

 describing the table of contents. This is not attempted with 

 the larger and more general works. With the exception of a 

 few instances, no attempt has been made to estimate the value 

 of the various papers, and some have been included because 

 of their historic interest. A list of geological maps, including 

 those used as illustrations accompanying reports, follows the 

 list of papers. The articles catalogued are numbered serially. 

 Numbers from 500 upward are used for the maps. 



Thanks are due to Mr. Freeman Ward for valuable and 

 expert assistance in preparation of the notes, and to Miss 

 Elfreda Cutting and Miss Lucy Bush for assistance in prepara- 

 tion of the Index. 



The writer will be pleased to receive notice of errors in this 

 bulletin, especially of omitted articles.
