New Brunswick, Maine, and Eastern Canada, 163 



port on the geology of New Brunswick; and specimens were 

 shown to me several years ago, by the late Professor Kobb of 

 Fredericton. Those from Perry are mentioned in the report of 

 Dr. Jackson on the geology of Maine, and have also been no- 

 ticed by Prof. Rogers in the proceedings of the Natural History 

 Society of Boston, No adequate description of them has how- 

 ever yet been published ; and it is to this task that I would 

 address myself in the present paper. I shall notice first the 

 plants from St. John, next those from Perry, and finally a new 

 form from Gaspe. 



1. St. John, New Brunswick. 



The city of St. John stands on the rocks constituting what I have 

 elsewhere termed the coast metamorphic belt of New Brunswick,* 

 an irregular ridge rising through the Carboniferous rocks, and 

 extending from Shepody mountain south-westward along the 

 north side of the Bay of Fundy to the St. John River, westward 

 of which it expands into a broad band of metamorphic and 

 plutonic rocks, extending into the State of Maine. In the vicin- 

 ity of St. John these rocks consist principally of white and gray 

 crystalline limestone, hard shales and slates of various colours 

 and qualities, quartz rock, and indurated gray sandstone. With 

 these are associated syenite, greenstone, and trappean rocks, 

 some of the latter appearing to be interstratified. The crystal- 

 line limestone is of great thickness and destitute of fossils; but 

 contains small quantities of graphite. In the shales near the 

 limestone is a regular bed of graphite, attaining in places a thick- 

 ness of four feet. It is of coarse quality, and retains obscui^e 

 traces of vegetable structure. Some of the beds of sandstone and 

 shale contain numerous fossil plants, their carbon being in the 

 state of graphite, and the fragments, though abundant, not easily 

 studied, owing to their imperfect preservation, and the hardness 

 of the enclosing rock. A bed of sandy shale is filled with frag- 

 ments of Lingida, which were discovered by Prof. Rogers, but 

 which neither he nor Mr. Billings, to whom I have shown speci- 

 mens, can refer to any known species.
