No. 1.] BAILEY — GRAND ^lANAN. 51 



a nearly pure white colour, rises into a conspicuous ridge, having 

 a low westerly dip (W. lO'^ N. > 20*^), and a breadth of over 

 one-eighth of a mile.^ It rests upon soft dark green shales, and 

 with these extends through the length of the island, reappearing 

 in Grull Rock and in Chalk Cove towards the northern end of 

 Ross Island. This large island, as well as the shore from Wood- 

 ward's Cove to Grand Harbour, I had not leisure to examine, 

 but in passing around the shore of the last named haven, and 

 thence along the beach to Red Head, was enabled to obtain a fair 

 idea of the structure of the remaining portion of the metamor- 

 phic belt. 



Along the western side of Grand Harbour the strata exposed 

 to view, near its head, are greenish-grey chloritic and grey feld- 

 spathic schists, and grey feldspathic sandstones, with a strong 

 slaty cleavage and variable dip ; while nearer its entrance there 

 are with these fine-grained greenish and purplish rocks, containing 

 epidote, and more or less amygdaloidal. A few beds of fine- 

 grained grey felsite, or felsite with an admixture of quartz and 

 chlorite, or talcoid mica, are intercalated with these. The dip 

 here is N. 60 to 70 E. > 30^ to 50°. Similar beds, but with a 

 larger proportion of shales, sometimes purple and sometimes dark 

 green with films of chlorite, skirt the shore westward of the 

 entrance of the harbour, forming the promontories of Mike's and 

 Oxnard's Points. A long curving beach, broken at intervals by 

 beds of yellowish-grey slaty felsite, separates this point from a 

 line of low bluffs running out and terminating in the promontory 

 of Red Head, The beds exposed in these bluffs bear much re- 

 semblance to some of those described above, as seen upon the 

 shores of Flag's Cove, towards the head of the island. They are 

 grey and bluish-grey (sometimes purple or black) fine-grained 

 beds, conspicuously ribbon-banded and thrown into innumerable 

 sharp corrugations. With these are grey feldspathic sandstones, 

 coated M'ith specular iron, and coarse green chloritic beds, simi- 

 larly plicated, but having a general northerly dip at an angle of 

 about 30°. Towards the head the finer beds predominate, be- 

 coming soft and rubly and conspicuously stained with red oxide 



* The quartz rock is here associated with dark grey fissile shales 

 and green chloritic schists, dipping S. 40 W. > 30. It has almost the 

 aspect of a white quartz vein. Similar rocks form conspicuous cliff.i 

 on the western side of' Whitehead Island but have not been visited 

 by me.
