SOME LOCAL DETAILS. 173 



province, where deposits of this kind occur similar to 

 those found in Canada and in Maine, though apparently 

 on a smaller scale. These deposits, as they occur near 

 St. John, consist of gray and reddish clays, holding fossils 

 which indicate moderately deep water, and are, as to 

 species, identical with those occurring in similar deposits 

 in Canada and in Maine. They would indicate a some- 

 what lower temperature than that of the waters of the 

 bay of Fundy at present, or about that of the northern 

 part of the gulf of St. Lawrence. 



In Bailey's Report on the Geology of Southern New 

 Brunswick, Professor Hartt has given a list of the fossils 

 of these beds, as seen at Lawlor's lake, Duck cove and 

 St. John, which I re-published with some additions in 

 Acadian Geology. 



These New Brunswick beds are strictly continuous 

 with, and equivalent to those which extend along the 

 coast of New England, and thence ascend into the valley 

 of lake Champlain, while on the other side they may be 

 considered as perfectly representing in character and 

 fossils the Leda clay of Eastern Canada. They are 

 remarkably like both in mineral character and fossils to 

 the Clyde beds of Scotland, which are probably their 

 equivalents. The points of resemblance of the Leda clay 

 of the coast of Maine, and that of the St. Lawrence, and 

 Labrador, were noticed by me in my paper of I860, 

 already referred to, and have been more fully brought 

 out by Dr. Packard, who describes the Leda clay as it 

 occurs at several localities from Eastport to cape Cod. 

 Along this whole coast it retains its Labradoric or gulf of 

 St. Lawrence aspect, though with the introduction of 

 some more southern species, and the gradual failure of 

 some more arctic forms. South of cape Cod, as in the
