A year ago, when passing through City Road, St. 

 John, in an electric ear, tlie writer caught sight of a 

 sloping ledge of slate, which appeared to show evidences 

 of faulting. On re-visiting the spot afterward he found 

 that the appearance was not illusory, but that there had 

 been uplifts of these slates along old fault lines since 

 Glacial times. 



An examination of the rock surfaces at other points 

 showed that this was not a solitary instance of displace- 

 ment, but all along this hillside — for a distance of half a 

 mile — great numbers of these faults could be seen. 

 Though the individual displacements were generally 

 slight, yet owing to the great numbers that exist the 

 change of level is very considerable, and the importance 

 of these faults is greater that at iirst sight would appear. 



Their influence on the structural geology of this 

 district seemed of sufiicient importance to make a more 

 careful examination desirable, and the writer accordingly 

 undertook a rough measurement of the faults at the more 

 important exposures. 



At City Road, just under the City Hospital hill, are some 

 ledges on the south side of the street which project above 

 the street level, the street having been partly excavated 

 Irom the solid rock at this point. These ledges have a
