North of Oak Island is Boot Island, which is separated from the 

 mainland, called Long Island, by a narrow channel, formed within 

 the last two centuries. North of this channel is a buried forest, 

 exposed at low tide. North of Boot Island, and on the north side 

 of Long Island, are exposures of red sandstones with occasional thin 

 shales in which Dr. H. M. Ami reports the presence of Estheria ovata. 1 



Fig. 26. — Details of the Triassic sandstone and conglomerate 30 feet above the 

 base of the Annapolis formation, one mile east of Lower Economy. 



At Wolfville the basal Triassic unconformity is exposed in a 

 small brook west of the buildings of Acadia College, resting hori- 

 zontally on upturned and beveled slates of the Meguma series. 2 

 The basal unconformity is again exposed at Kentville, just below 

 the mill on Black River. 3
