I'ibbanded, and exhibit numerous and abrupt corrugations. Their 

 general dip, however, is northward (N. 20^ to 30" E.). 



The section afforded by the peninsula above described between 

 Whale Cove and Flag's Cove may be taken as affording a fair re- 

 presentation of the whole metamorphic belt of the Eastern shore of 

 Grand Manan, strata similar in their general aspect to those al- 

 luded to being met with at various points along the latter as well 

 as in the adjaceut islands. With these, however, are some beds but 

 imperfectly represented or altogether wanting in the area first al- 

 luded to. 



Along the Western side of Flag's Cove the metamorphic belt 

 is greatly reduced in breadth, being confined to a narrow strip 

 along the shore and to a series of ledges mostly covered by the 

 tide. The rocks exposed here are coarse greenish-grey somewhat 

 chloritic sandstones, with strong slaty cleavage, having numerous 

 imbedded nodules of mixed quartz and spar from a quarter of an 

 inch to two inches in length, besides numerous little crystalline 

 spots resembling spathic iron. Beds of precisely similar character 

 may be seen on Big Duck Island several miles to the southward, 

 being here associated with blueish-grey somewhat unctuous feld„ 

 spathic schists, and pale grey dolomites. There are also upon this 

 island (beneath the first named beds) white-weathering nacreous 

 slates with green and purple shales, the whole porphyritic as 

 above with numerous little rhombohedral crystals, and more or 

 less filled with sparry nodules. The white nacreous slate has 

 been examined by Dr. Sterry Hunt, who finds it to consist of an 

 admixture of silicious matter with a hydrous potash-mica, con- 

 taining only traces of magnesia and iron. The imbedded crystal- 

 line spar is a triple carbonate, consisting of carbonate of iron 

 39.20, carbonate of magnesia 40.40, carbonate of lime 20.40 ~ 

 100.00. These beds have here a breadth of over 100 rods, and 

 rest upon coarse purplish-grey quartzose grits, the general dip 

 being westerly at an angle of about 60*^. The whole series is 

 evidently the same as that of Flag's Cove, with which these 

 rocks are connected throuo'h those of Lone: Island. 



Along the road connecting Flag's Cove with Woodward's 

 Cove and Grand Harbour the rocks met with are chiefly grey light- 

 weathering felsites and coarse grey feldspathic sandstones and 

 slates, much broken and seamed with quartz, and sometimes be- 

 coming true quartzites. Similar rocks form Nantucket Island, 

 near the entrance of the last named Cove, but here the quartzite of
