 now known as St. Martin. The Triassic extends from West 

 Quaco to Melvin's Beach, and includes the large area mapped as

 Mountain, the Annapolis Valley, and South Mountain, on the south. A, pre- 

 Cambrian; D, Devonian; Gr, Devonian granite; J, Triassic. 



Fig. 8. — The contact of the lower red sandstone and the Quaco conglomerate 

 above, near Macomber Brook, Quaco. The contact is a conformity. There is a 

 very sharp boundary both in lithology and in color which is obscured by a pile of talus 

 in the center of the picture. * 



Lower Carboniferous on the map of the Geological Survey of 

 Canada, issued in 1880. The length of the area is 7I miles and 

 the width 3 miles, as shown in Fig. 5. The shore exposures furnish 

 an excellent structural cross-section of the area.
