uplifts occur have the usual course. East of the end of 

 Peel street, in a widtli of eight feet, four faults were 

 noticed, varying in throw from one-qnarter of an inch 

 to one inch. The down-throw was on the north side. 

 West of the end of Peel Street are several small 

 exposures. At one the fine, dark slates are exposed for 

 a breadth of fifteen feet. Here arc twelve fanlts, varying 

 from half an inch to one inch, and one fault with a throw 

 of five inches. All have the down-throw on the north 

 side. The stride here have a course sonth, twenty-five 

 degrees west. Further along the hillside, opposite Pond 

 street, there are several faults with down-throws to the 

 north. These are in black slate, and so Avorn by the 

 weather that they could not well be measured. Here the 

 stria' have a course south, thirty degrees west, a greater 

 westing than at the other localities named above, because 

 the ridge bounding the valley to the south here begins 

 to descend westward toward the sea level. 



A few observations outside the city limits have been 

 made, which show the presence of these post-glacial 

 faults at other points. Thus, at the north-east corner of 

 the Church of England burying-ground, at the eastern 

 border of the city, there is a glaciated ledge exposed, 

 showing two slight post-glacial faults, of one-quarter of an 

 inch each, having the down-throw on the south side. At 

 the head of Courtenay Bay, on the eastern side, the ledges 

 at the shore, and near by on the highwa}", show several 

 post-glacial faults, with down-throws on the north side. 



The excellent preservation of the pre-glacial faults in 

 the " Valley " at St. John is due to various causes. In the 

 first place the rock along the hillside consists of the fine 

 shales of the Bretonian division of the St. John Groups 

 which are well adapted to receive the finest strire, and they
