Among the inany attractions which St. John offers to 

 an intelligent visitor, the variety and interest of the rocks 

 in and around it, is by no means the least. Few places, if 

 any, afford a greater namber of geological formations with- 

 in so limited an area, and the scanty soil, which is the des- 

 pair of the farmer, is hailed with delight by the student of 

 lithology. Yet, on account of its distance from the great 

 centres of learning in the CTnited States and in Canada, 

 the details of its geology have been worked out chiefly 

 by local students, and their excellent work is perhaps not 

 as well known elsewhere, as it otherwise would be. The 

 complicated structure of the neighborhood has made it 

 impossible to get satisfactory results without the most 

 careful and accurate study, and this cannot so well be 

 made in the less settled districts at a distance from the 

 city. But it may, I think, be safely said that southern 

 New Brunswick has been as carefully surveyed as is 

 practicable until it becomes more thickly settled, and 

 hence more accessible. 



In the present paper I do not propose to deal much 

 with the structural geology of the country, but rather to 

 discuss to some extent the character of the various
