REPORT OF THE DIRECTOR I913 79 



The stratigraphic analogies between the Carbonic of the Mari- 

 time Provinces and that of England and the north of France 

 are everywhere remarkable. They were pointed out long ago. But, 

 tectonically speaking, there has been no direct connection between 

 the Appalachians and the European coal chain. In Canada the 

 Appalachian chain is a chain of Middle Devonic age, thus a 

 Caledonian chain ; and the movements which have affected it, at 

 different times, in the Carbonic, the Permic, perhaps also at 

 the end of the Trias, are very slight movements, which are en- 

 titled to be designated only as posthumous movements. Farther 

 southwest, in the United States, these posthumous movements be- 

 came gradually more intense and have built up a real chain, a true 

 range of American Altaids in the exact prolongation of the 

 Canadian Caledonids.
