were, in addition, the equivalents of those fossil plants from Lan- 

 caster in New Brunswick, " held to be of Devonian age," thus 

 implying- that whatever one series was, the other must be also,, 

 and hence the Lancaster " fern ledges" must also have a Carbon- 

 iferous facies though coloured Devonian. 



Later, in the '* Summary Report of the Director of the Geo- 

 logical Survey Department for 1898" (p. 181), I made the following 

 statement : " Regarding the general results of this Devono- 

 Carboniferous problem from a palaeontological standpoint it would 

 appear, in reviewing the value and amount of the evidence afforded 

 by fossils obtained during the past three seasons, that, in so far as 

 the faunas are concerned, they clearly indicate a ' Carboniferous 

 facies.' " 



Subsequently, in the " Summary Report of the Director of 

 the Geological Survey Department for the year 1899" (pp. 201-203), 

 the writer gives the result of an examination made by Mr. R. 

 Kidston, F.G.S., of the material collected from the so-called 

 " Devonian" strata of Nova Scotia, and as regards the rocks of the 

 Horton formation he says they "appear to be undoubtedly Lower 

 Carboniferous.". ... "there is no evidence at all to support the 



opinion that they are of Devonian age" "all the evidence 



derived from the study of these fossils points very strongly against 

 this view." Of the Riversdale series of plants, Mr. Kidston gives 

 them " a pronounced Upper Carboniferous facies, and markedly 

 possess the characteristics of a coal measure flora. Judged from 

 a European comparison, no other conclusion can be arrived at." 



Such evidences, relative to the Devono-Carboniferous problem 

 and the various results given, all seem to indicate that both in 

 Nova Scotia and New Brunswick we find a series of fossil 

 plants which in one province had been assigned to the Carbon- 

 iferous and in the other to the Devonian, but whose characters 

 and affinities as adduced and understood respectively necessarily 

 place them both in the Carboniferous system. 



For brief notes upon the succession of the strata in the 

 Carboniferous of certain portions of Nova Scotia with special 

 reference to the Union and Riversdale formations the reader is 

 referred to the writer's paper on that subject in the Transactions 

 of the Nova Scotian Institute of Science, Vol. 10, 1900, pp. 162-1
