are seen until we cross the road. About feet south of the 



road the mountain series is reached. Here are outcrops of slates. 

 Ascending the mountain we find indications of the red slates of pre- 

 ceding sections. From this the red slates pass on westward and 

 seem to terminate in the mountain beyond. No traces of them could 

 be found west of the mountain. Extending the line of section to 

 the southward of this mountain we have slates, very hard grits, 

 (ash)? and petrosilex. Spanning a precipice and deep gulch, we 

 have again petrosilex, and at a distance of about a quarter of a 

 mile we reach great outcrops of granitoid rocks — Syenites or 

 diorites? I am not precisely certain. 



Section 9th. — Smith's Brook. 



At the mouth of the Brook the waters fall over strata B' having 

 characteristic fossils. Up to the bridge and beyond it the same 

 strata continue. Farther up there is another fall. The rocks here 

 are of C Upper Arisaig ; this is evident from the fossils found in 

 them. In the field above the brook C fossils are abundant ; these 

 strata extending westward are well exposed on the road, above it, 

 and in the fields. The rocks are coarse and hard, giving boldness 

 to the outcrops. 



Section 10th. — McAdam's Brook. 



• 



This section begins with strata of the lower part of C of the 

 upper series — Aymestry limestone. These strata are very fossil- 

 iferous. It continues through outcrops of the same strata having 

 abundance of fossils a degree higher in the series. It passes 

 through strata having numerous fossils of D Upper Ludlow. At a 



distance of feet there is a small waterfall with strata having 



a low dip. 



Continuing the section, we have a broad band of red slates 

 having a high dip. These extend to the top of the brook, termina- 

 ting in a swamp, where the brook takes its rise. These slates are 

 apparently non-fossiliferous. I have designated them E as already 

 intimated.
