Knometres boTiiferous Conglomerate" extends for many 

 miles both to the east and west, in the form of a 

 band varying in width between i and 2 miles 

 (i-6 km. and 3-2 km.). Along the northern 

 edge of this band of "Carboniferous Conglome- 

 rate" occur so-called Devonian strata of the 

 Riversdale-Union group, and from a point not 

 far east of East Minas station, the same "Devo- 

 nian" beds lie along the southern boundary of 

 the Conglomerate series between it and the 

 Triassic. The "Carboniferous Conglomerate" 

 measures strike in a general east and west 

 direction and dip either to the north or south at 

 angles of 20° to 75°. 



One mile (i-6 km.) west of East Minas 

 station, the railway crosses Folly river. This 

 river flows across the band of "Carboniferous 

 Conglomerate" whose southern boundary lies 

 J mile (o-8 km.) north of the railway. The 

 strata of the conglomerate series comprise not 

 only conglomerates but also reddish and greyish 

 sandstones and shales with very thin seams of 

 coal. By Fletcher the conglomerates are des- 

 cribed as holding fragments of the " Devonian" 

 rocks. By Sir William Dawson, the strata were 

 classed with the "coal measures" and not with 

 the basal Carboniferous as Fletcher did. 



Beyond the crossing of Folly river, the railroad 

 gradually approaches the southern boundary 

 of the "conglomerate series" and finally, after 

 curving around to a nearly north course, enters 

 the area of these rocks. The railway passes 

 through several cuttings in inclined red conglo- 

 merates and sandstones belonging to this series.

163-0 km. From Londonderry station, situated within the 

 area of the "Conglomerate" series, the railway 

 as it climbs the southern slope of the Cobequid 

 hills, runs in a northeasterly direction towards 

 the valley of Folly river. Cuttings in red 

 conglomerate and sandstone, and in red sand- 

 stone and shale, occur along the railway. As 

 the railway approaches Folly river, a view is 

 afforded to the south and east over the low
