LETTER OF TRANSMITTAL 



Department of the Interior, 



United States Geological Survey. 



Cambridge, Massachusetts, March 2, 1896. 

 Sir: I have the honor to submit herewith, for publication, a report on 

 the geology of the Narragansett Basin. This report contains the result of 

 a considerable amount of work done by me or under nry direction since I 

 became an officer of the Survey. In part, however, it is the result of 

 studies undertaken before that connection was established. The object of 

 the report is to set forth the results so far attained in the study of a field 

 which presents singular difficulties in the way of its interpretation, and 

 which will require the observation of many other students before it becomes 

 thoroughly well known. Since the preparation of the report was under- 

 taken I have been ordered to extend the results of a general nature there 

 attained to other similar basins on the Atlantic coast. On this account 

 it has seemed desirable to postpone a thorough consideration of many 

 portions of the subject until other parts of the Atlantic coast have been 

 examined. 



I have the honor to remain, very respectfully, your obedient servant, 



N. S. Shaler, 



Geologist in Charge. 

 Hon. Charles D. Walcott, 



Director United States Geological Survey.
