LETTER OF TRANSMITTAL 



To His Excellency Phillips Lee Goldsbokough, 



Governor of Maryland and President of the Geological Survey Com- 

 mission, 



Sir: — I have the honor to present herewith the sixth volume of a series 

 of reports dealing with the systematic geology and paleontology of Mary- 

 land. The preceding volumes have dealt with the Devonian, Lower 

 Cretaceous, Tertiary, and Quaternary deposits, and the remains of animal 

 and plant life which they contain. The present volume treats of the 

 Upper Cretaceous deposits and their contained life, a knowledge of which 

 is very important from an educational and scientific standpoint. I am, 



Very respectfully, 



William Bullock Clark, 

 State Geologist. 



Johns Hopkins University, 



Baltimore, December. 1915.
