ROCKS ON THE THLEW-EE-CHOH. 15J 



At noon the weather cleared, the canoe was 

 put in order, and having made a cache of 

 the spare baggage, we began to move to the 

 river. The portage from Lake Aylmer is short 

 of a mile, and in that space intervenes the small 

 sheet of water already referred to. The actual 

 height of the dividing land is consequently not 

 more than two feet. We pursued exactly my route 

 of the previous day, and soon came to another 

 lake, at the north-eastern extremity of which 

 the sand-hills dipped into the water. A crooked 

 rapid, beset with large stones, impeded us so 

 much, that it was 9 p. m. before we encamped.

 which exposed inconsiderable masses of rocks, 

 while the debris thickly strewn over every 

 part of the vallies formed the bed of numer- 

 ous ^ponds and water-courses, now dry. A 

 portion of rock having a more compact form, 

 broke ground near the river, and though not ex- 

 tending more than thirty yards to the eastward, 

 terminated in cliffs of twelve feet high. These 

 were the first rocks on the Thlew-ee-choh, and 

 were principally gneiss. 



The thermometer was 33° when we set out 

 at 4 a. m. of the 31st of August, and followed a 

 small lake until it ended in a rapid ; so choked 

 by immense boulders that small as the canoe
