G. F. MATTHEW ON THE ORGANIC REMAINS OF THE 



in the Canadian IsTaturalist and in the Journal of the Geological Society, a few remarks on 

 the lithology, stratigraphy and distribution of the older deposits of this neighbourhood may 

 not be unacceptable. 



" The Devonian age of certain deposits in Gaspé, ISTova Scotia, and Maine, had been 

 recognized, before the existence of strata of this age in î^ew Brunswick was ascertained. In 

 various parts of the Bay of Fundy, red sandstones had been observed, some were referred 

 to the Carboniferous period, while others were found to be of still later origin ; the deposits 

 to which these remarks relate were all classed as Silurian. 



" In June, 1861, Dr. Dawson asserted the Devonian age of the sandstones of Perry in 

 eastern Maine (and in consequence those of St. Andrews, N. B.) from certain plants sub- 

 mitted to him for examination. Dr. C. T. Jackson had previously suggested this as the 

 probable age of these rocks. The additional proofs accumulated by Prof. C. H. Hitchcock, 

 have thrown much further light on their history and their Devonian age is now clearly 

 recognized. 



" On the eastern side of the harbour of St. John, and extending many miles along the 

 coast, are extensive sedimentary rocks of great thickness, consisting almost entirely of frag- 

 mentai rocks, usually of coarse materials, varied by the addition of numerous beds of volcanic 

 origin. The lower members of this formation pass beneath the harbour and extend a few 

 miles along the coast to the west^^'ard. It is in this direction that vegetable remains of the 

 period when these rocks were formed, have been found in the greatest abundance, and best 

 state of preservation. The examination of these fossils has enabled Dr. Dawson to refer the 

 strata in connection with them to the Chenuuig and I'ortage groups of I^ew York geologists.'

"In the map and section accompanying these observations I have endeavoured to show 

 the distribution of the various groups of strata, and the manner in which they are tilted and 

 folded. Three principal folds in the strata (including those from the Laurentian to the 

 Devonian) are observable. Of these the northwestern skirts the south side of Kcnnebcckasis 

 Bay, a lake-like expansion of the lower part of that river (not shown on this maii). The 

 southeastern runs parallel to that part of the Bay of Fundy eastward of Cape Spencer, and at
