cow.] JAMES' BAY. 51 J 



is fifteen chains long, and crosses a low rocky ridge, ending in a small 

 lake half a mile across to the outlet, where the river is again obstructed 

 by heavy rapids, causing a portage of fifteen chains, to another lake 

 partly covered with many islands. 



H-ere an east course was followed for one mile and a quarter past a 

 long narrow pointjprojecting from^its west side, then turning north 

 two miles and a half, the outlet was reached, and the river, here forty 

 yards wide, descended one mile and three quarters past small rapids 

 to Pos-pis-ka-ga-mi Lake. One mile^to the east of the entrance of the 

 river another large stream called Ka-mo-chi-mo-pas-ti-quo Eiver enters. 

 This lake is four miles long from south-east to north-west, with an 

 average breadth of a mile and a half. Its western shore was followed 

 three miles to the river flowing out. 



Beyond this the river passes through no more lakes and flows in a 

 distinct valley. 



.The country surrounding the last lakes is nearly flat and very Timber, 

 swampy, with a few low ridges of hills, littered with large quantities of 

 rounded boulders. The trees continue to grow smaller, and are almost 

 wholly confined to the valleys and low lands. Black spruce predomi- 

 nates with some tamarac, and a very few banksian pine. 



On the portage to Masquachiwi Lake the rock is a coarse-grained 

 pink hornblende gneiss. Strike N. :10° W. A fine grained compact 

 pink hornblende mica gneiss, holding dark hornblendic segregations, 

 striking N. 70° W., was seen on the portage to Lake Mishiminiwaten. Rook3 - 

 On the large island in that lake a fine-grained reddish grey mica 

 gneiss occurs strike N. 75° W. Exposures of red and grey fine grained 

 mica gneiss are to be seen at the rapid above Kachinwastegin Lake 

 strike N. 82' VV. On the portage below the same lake, the rock is a 

 grey fine-grained, mica hornblende gneiss, cut by largo veins of light 

 pink orthoclase. Strike N. 75° W. 



At a small island in Pospiskagami Lake is a dark red fine grained 

 mica gneiss made up largely of flesh red orthoclase, strike N. 72° W. 



Lower Great Whale River. 



The river where it leaves Lake Pospiskagami is one hundred and character of 

 fifty yards wide, is quite shallow, and for two miles and a half flows river " 

 with a swift current between low rocky banks, cut by uumerous small 

 bays. Here a rapid of eight feet is passed by a portage of fifteen 

 chains; followed by another stretch of swift water for two miles and a 

 half to a fall of eight feet. Below this, the river is three hundred yards 

 wide and very deep, passing JS".W. three miles through a straight gorge 

 with rocky hills on either side, which rise from two to three hundred
