The Devonian of the Acadian Provinces. 337 



vicinity of St. John, New Brunswick. From these he 

 evolved a long list of species which to his mind at least 

 conclusively established their horizon as Devonian also.^ 

 It is unnecessary to go into the details of this study since 

 they are fully stated in the several reports of the 

 Geological Survey on the fossil plants of the Silurian and 

 Devonian extending from 1871 to 1882."^ The results of 

 his work were also summed up in a report to that Depart- 

 ment in 1870-71 by Messrs. Bailey and Matthew. 



The remark by Mr. Wliite, on page 6 of his pamphlet, 

 that " the determinations of Sir William in regard to the 

 St. John plant remains were forced upon him by the 

 finding of the stratigraphers " can therefore be assumed to 

 be without foundation and to be misleading. More 

 especially since the details of th^e stratigraphical sequence 

 of tliese rocks in Southern New Brunswick were worked 

 out carefully some years subsequent to his determination 

 of the plant remains ; and it may be stated that the 

 eouclusions arrived at by the stratigraphers abundantly 

 confirmed the decision which had been reached by him 

 some years previously. The great series of beds known in 

 the southern part of the province as Devonian, and 

 diviaed'lnto Mispec, Cordaite shales and Dadoxylon sand- 

 stone, were conclusively found tO' be beneath the lower ' 

 Carboniferous limestones as also beneath a considerable 

 thickness of shales, sandstones and conglomerates which 

 also underlie these. 



Not only so, but they are known to underlie in great 

 part a series of sandstones and shales, known as the Perry 

 sandstone group,^ concerning the age of which, as repre- 

 senting the upper member of the Devonian, Sir William 

 apparently never had any doubt to the last of his investi- 

 gations in this field.
