MOVEMENTS OF THE EARTH'S CRUST AT ST. JOHN. 37 



111 this space of one Iniiidred and fifty-six feet, witli 

 sixty faults, all the down-throws were on the north side, 

 Avith one exception, marked with an asterisk, where the 

 down-throw is on the south side. 



For spaces of forty feet, four feet and fifteen feet, 

 respectivel}', in and heyond this space, the ledges were 

 either covered hy soil, or so worn and broken that the 

 faults could not be traced. Tliere Avere diagonal faults 

 at this Rock street exposure, but not being well shoAvn, 

 they were not measured. 



Further along this hillside, at the east end of Charles 

 street, there are other ledges exposed. Here the strife 

 run south, fifteen degrees west. The principal set of 

 fault planes has a course of north, sixty degrees east, 

 and a steep hade south-Avest. The doAvn-throAA% as at 

 the tAvo former places, is at the north side of the fault. 

 The diagonal faults are aa'cII shoAvn here ; one set has 

 a course from east to AA^est and a hade of about fifty 

 degrees to the south ; along these fault lines the down- 

 throw is on the north side. 



From Charles street AA^estAvard to ScAA^ell there are no 

 good exposures, partly OAA^ng to the land being covered 

 l)y buildings, and partly to the fact that there has been 

 considerable filling in at Garden and Dorchester streets. 



Proceeding toAvard the Avest end of the " Valley " the 

 slate ledges are again exposed along the hillside south of 

 ScAvell street, at the north end of Peel street. This is at 

 the junction of the fine black shales of the Bretonian 

 division of the St. John Group Avith those coarser, 

 lighter coloured slates of the Johannian diA'ision. The 

 exposures are of small extent, but there are seA^eral 

 of them. The glacial stri;* here run south, tAventy-fiA'-e 

 degrees Avest, and the fault planes along Avhicli the
