phous felspathic rock near the entrance of the Bigdequash, 

 averaging 'J 6 per cent of copper, and increasing in thickness, 

 as they are further removed from the surface. The new red 

 sandstone and conglomerate appear again at Mascarnie head, 

 but are much disturbed by trap dykes. Limestone is found 

 on the shores of I'Etang Harbour, the course of the strata 

 being N.E. and S.W., the dip N.W. at an angle of 80^ ; it is 

 also penetrated by numerous veins of greenstone in the di- 

 rection of the strata. 



These same formations prevail throughout the adjacent 

 islands, as well as along the coast to the entrance of the river 

 St.-John. 



The section presented on examining the interior, from the 

 mouth of the Magaguadavie to the river Oromocto, in- 

 cludes a succession of the same formations as already de- 

 tailed, with the addition of shales, which occur on the banks 

 of the north branch of the latter river, and which abound 

 with the remains of plants. Ten miles up this stream there 

 is an outcropping of coal between strata of bituminous 

 shale, the beds increasing in thickness in proportion as they 

 are deeper situated. 



Eastward of the head of the Oromocto, the slate appears, 

 and is succeeded occasionally, by the old red sandstone, 

 and carboniferous limestone, dipping beneath that part of 

 the coal-field, which is situated beneath the south side of the 

 St.-John. Thus, it may be said, that the district, the sub- 

 ject of Mr. Gesner's first report contains a series of rocks 

 from the carboniferous limestone to the granite, and seldom, 

 as our author remarks, are the several formations found 

 succeeding each other in the great scale of superposition 

 with that beauty, regularity, and order, which they here dis- 

 play. 



The coincident appearances which Mr. Gesner records 

 throughout his first report, establishes the correctness of
