NOTES BEARING ON THE DEVONO-CARBONIFEROUS 

 PROBLEM IN NOVA SCOTIA AND NEW BRUNSWICK. 



(Based on Dr. David White's recent Report entitled : — 

 " The Stratigraphic Succession of the Fossil Floras of the 

 Pottsville Formation in the Southern A nthracite Coal Fields of 

 Pe7insylva?iia.'') 



By H. M. A.Mi, of the Geological Survey of Canada. 



From recent studies pursued with great care and diligence, 

 extending over a period of many years in the Floral zones of the 

 Pottsville formation in Pennsylvania and the Eastern States, Dr. 

 David White, Palaeozoic palaeobotanist to the United States Geo- 

 logical Survey, has given to the world a most elaborate and com- 

 prehensive report in Part II. of the 20th Annual Report of the 

 United States Geological Survey — General Geology and Palae- 

 ontology — in which the results there given have considerable 

 bearing upon and are closely in line with the results obtained in 

 Canada during the last few years by the writer. 



In May, i8g8, I had the good fortune of visiting the Anthra- 

 cite coal-fields of Pennsylvania, in company with Dr. David 

 White, and of examining several of the sections in the Carbon- 

 iferous system of that state, with a view of obtaining evidence 

 that would tend to throw light upon the Devono-Carboniferous 

 problem in Nova Scotia and New Brunswick. Near the town of 

 Pottsville, at Maunch Chunk, Tremont, Brookside, and many 

 other localities, typical sections were observed, and a number of
