Kilometres series, an area of Pre-Cambrian rocks which 

 extends southward to the Altantic. For the 

 first mile and a half, an ascending section of 

 alternating beds of quartzite and shale, striking 

 east and west, and dipping south at high angles, 

 is traversed to a point 400 feet (120 m.) north 

 of Lily lake, where the intervening syncline 

 between the Shubenacadie-Grand lake anti- 

 cline and the Oldham anticline is crossed and 

 can be located a short distance on left by several 

 outcrops of quartzite curving on the western 

 plunge of the fold. 

 2-5 m. Horn Brook — Alt. 247 ft. (75-3 m.). In 



4-0 km. the next half mile the same strata are again 

 crossed but in descending order, to the Oldham 

 anticline which crosses Horn brook 100 feet 

 (30 m.) above the fall on the right. The 

 Dowell lead may be observed on the left in 

 an open-cut 200 feet (60 m.) north of the fall.

oft. Horn Brook — Alt. 247 ft. (75-3 m.). From 



o m. Horn brook at the western extremity of the 



district, the anticline strikes easterly along 

 a ridge which is followed by the road as far 

 as Black brook. Going easterly along the road, 

 the following observations may be made reckon- 

 ing the distances in feet from Horn brook. 

 1,500 ft. Anticline exposed crossing road obliquely 



457 m. from right to left; apex plunges west about 

 20 ; strata curve and dip north and south at 

 low angles increasing rapidly to 70 to form 

 a transversely symmetrical and sharp fold. 

 Cleavage is perpendicular.
