 Another Kct of •grooves, near the centre of the i.shind, was found to run 

 S, 05" E. mug., or about N. 75° E., true. On the east side of the ishind* 

 the groovos run N. 35° E. mag. or N. 5° W., true. 



The forms of the roches moutoane ami other evidence afforded by 



the grooving und fluting of the rocks of this ishmd themselves, go to- 



show that the direction of the glaciating tbrce was from the southwai-d 



and south-westward and not from the contrary direction. ._ Eaised 



beaches are well marked up to the highest point of the island, 



about forty or fifty feet above the sea level. Much of the shingle of the- 



island consists of dolomite of the Manitounuck group, and this fact is 



a further evidence that the drift in this region came from the south- 

 Northward . , r. 1 1 1 . 1 > 1 



course of drift, ward, Since these rocks have, as yet, been found only on the islands and 

 shore of the Eastmain coast between Cape Jones and Cape Dufferin. The 

 islands further out to sea, opposite to this part of the coast are also 

 believed to consist of rocks of the Manitounuck group. Specimens, said 

 to have been broken from the fixed rocks of the Belchers, opposite • 

 Belcher Islands j^j^^,^ Whale River, were obtained at my request, from the Eskimo and 

 are found to consist of amygdaloid, white and groy dolomite, a soft 

 grey schist and columnar calcspar, the last named apparently from 

 a thin vein. 



All the larger islands of the Ottawa group are bare, rugged and 

 mountainous. The rocks of Perley, Pattee, Gilmour, Booth and Bron'- 

 son Islands appeared to be all the same as those of the small island 

 which has been described. The surface of the hills, which on Gilmour 

 Island rise to a height estimated to be about 1,800 feet, is eveiywhere 

 extremely rough and pitted in appearance. 



We found the small island, on which we landed, inhabite<l by con- 

 siderable numbers of walruses. Some white poi-poises or small white 

 whales ( Delphmopterus catodon, Linn.) were also seen in the vicinity. 

 The remains of a number of Eskimo camps and part of the skeleton of a 

 large whale were observed on the island. A few pieces of driftwood, 

 had been cast upon it.
