on the west bank. The fault on the eastern shore between 

 the Cambrian and Ordovician presumably continues on 

 the west side of the river and apparently passes close 

 to the small pavilion standing near the shore. The 

 fault at this place brings lithologically dissimilar Cambrian 

 beds into contact with one another. 



SUSPENSION BRIDGE TO SEASIDE PARK (FERN 

 LEDGES). 



The street car route from Suspension bridge to Seaside 

 park for a short distance follows a westerly course over- 

 looking the St. John river which is bordered on both sides 

 by Pre-Cambrian rocks consisting of crystalline limestone, 

 quartzite, etc., and large intrusive bodies of granite and 

 diorite. The street car route is situated on the northern 

 slope of a ridge which possibly is composed altogether of 

 unconsolidated materials since on the lower slopes, towards 

 the river, heavy cuttings reveal a very considerable thick- 

 ness of stratified clays and sands. 



Shortly after leaving Suspension bridge, the street car 

 route turns sharply to the southeast and passes along the 

 western edge of the summit of the above mentioned hill. 

 To the southwest extends a long broad valley joining the 

 valley of the St. John to the southwest. This valley is 

 continued on the eastern side of the ridge by the lower 

 reaches of the St. John river and by the valley running 

 northeasterly through St. John city. 



At the junction with the street car line leading eastward 

 to Carleton, are outcrops of dark, basic volcanic rocks. 

 Similar rocks outcrop at intervals along and at the end of 

 the street car route at Seaside park. These basic rocks form 

 a thick zone apparently interbanded or interbedded with the 

 lower portion of the Little River group. Similar rocks in 

 a similar stratigraphical position outcrop in St. John city 

 and farther east on the shore of Courtenay bay. The 

 igneous rocks vary considerably in appearance from 

 moderately coarse diabase to fine-grained, porphyritic 

 and amygdaloidal varieties. In places they appear to 

 have slightly metamorphosed the overlying sediments. 

 The basic igneous rocks possibly are eruptives, though it is 

 more probable that they form an intrusive, sill-like body.
