450 HONEYMAN ON GEOLOGY OF NEW BRUNSWICK. 



diorite, precisely similar to those of fossiliferous series of the I. C. 

 R. The St. John slates are well exposed in close proximity to the 

 rock, or associated with it. I have already referred to this in a 

 note on my paper on the I. C. R. sections ; I have been led to 

 regard these slates and the fossiliferous strata of the I. C. R. as 

 belonging to the same great period (Lower Silurian.) I must at 

 the same time acknowledge that I am rather disappointed in not 

 discovering some lithological resemblance between the St. John 

 .■dates and those of our City and environs. 



On the shore of Courtenay Bay, I found apparently overlying 

 the St. John slates, a dissimilar series consisting 1 of conglomerate. 

 Finely laminated red slate having crystalline limestone disseminated 

 iin amygdal form, silicious schists, slates and diorites. It will be 

 observed that the lithology of this series is much more varied than 

 the preceding. 



The sequence seems to be regular, and therefore was once 

 regarded by the N. B. geologists as a more recent formation than 

 the Lower Silurian slates. It was called the Bloomsbury group, 

 and was regarded as of Devonian age. I was guided in the exam- 

 ination of the locality by the paper communicated to the Geological 

 Society of London, by Prof. Bayley and Mr. Matthew. 



I may mention that although I now generally quote their 

 Report of the Canadian Survey, it was only after my return to 

 Halifax that I examined it, and compared it with my observations. 



I had had so much to do with supposed Devonian in Nova 

 Scotia, which had invariably turned out to be something else, that 

 I could not altogether accept the rock in question as Devonian. I 

 found however from the Report that these rocks are now regarded 

 as of Huronian age, the regularity of sequence being only apparent : 

 the older series having been brought up, and the seeming regular- 

 ity having been induced by a peculiar folding of the lower silurian 

 series — the folding on itself. {Vide the Report.} This arrange- 

 ment was ascertained by a more extended observation. 



In this way the Devonian of the locality became curtailed in its 

 proportions. Succeeding the Huronian there is another distinct 

 series also exposed on the shore of Courtenay Bay, consisting of
