HONEYMAN ON GEOLOGY OF NEW BRUNSWICK. 451 



metamorphosed grits, conglomerates, sandstones, and shales. At 

 first sight one might regard this as a hardened carboniferous series, 

 the black shales especially at the top have a carboniferous aspect. 

 This impression might be confirmed by the frequent appearance of 

 Flora having a carboniferous aspect. The unusual hardness of 

 the rock, especially evident when struck by the hammer, tends to 

 unsettle this opinion. I was fortunate enough to find, and at the 

 base of the series opposite Sheffield street, a fine specimen of the 

 characteristic Dadoxylon Ouangondia num. Daioson, associated 

 with calamites, &c. It was apparently in a favorable position for 

 easy detachment. My hammer and chisel were of no service. 

 Mr. Brittain, of the Gas Works, kindly gave me the assistance 

 of a workman, who with crow-bar and sledge-hammer, succeeded 

 in extracting the specimen. The rock is not distinguishable from 

 the quartzites of our gold fields, and equally hard. 



The constitution of the Fossils is also another peculiarity. The 

 bark of the calamites at this point has the appearance of graphite, 

 instead of coal or lignite, and the Dadoxylon, seems to be generally 

 calcified, sometimes converted into a beautiful marble, and the bark 

 concerted into graphite; this is the case with the specimen which 

 we extracted. In the Museum there is a beautiful polished section 

 of a trunk, found in the same locality by Mr. Brittain. Its diame- 

 ter is from eight to nine inches. It shows the internal structure of 

 the tree very strikingly. On the south shore of Carleton there are 

 ledges of slate which are regarded as the highest part of the series. 

 These produce a beautiful flora of asterphyllites, cordaites and 

 filices. The general character of the flora is considered to be 

 different from the carboniferous, and is regarded by Dr. Dawson as 

 Devonian. I received a beautiful collection for the Museum from 

 Mr. Brittain. 



Proceeding on towai'd Mispeck Point, we come to a very rough 

 and rocky region. There is a great band of conglomerates, red and 

 grey slates. These are seen traversed in all directions by quartz 

 veins — some of them are of great thickness. They were formerly 

 regarded by the N. B. Geologists as Devonian — (vide Geological 

 Journal — paper already referred to ; now they are regarded as 

 Huronian. Vide Report.
