THE UNKNOWN 



The daily observations of route and landmark I can 

 best leave for record on my maps. I had one great 

 complaint against previous explorers (except Tyrrell); 

 that is, they left no monuments. Aiming to give no 

 ground of complaint against us, we made monuments 

 at all important points. On the night of August 8 

 we camped at Cairn Bay on the west side of Casba Lake, 

 so named because of the five remarkable glacial cairns 

 or conical stone-piles about it. On the top of one of 

 these I left a monument, a six-foot pillar of large stones. 



On the afternoon of August 9 we passed the im- 

 portant headland that I have called " Tyrrell Point." 

 Here we jumped off his map into the unknown. I had, 

 of course, the small chart drawn by Sir George Back 

 in 1834, but it was hastily made under great dif- 

 ficulties, and, with a few exceptions, it seemed im- 

 possible to recognize his landscape features. Next 

 day I explored the east arm of Clinton-Colden and dis- 

 covered the tributary that I have called "Laurier 

 River," and near its mouth made a cairn enclosing a 

 Caribou antler with inscription "E. T. Seton, 10 Aug., 

 1907." 



Future travellers on this lake will find, as I did, 

 that the Conical Butte in the eastern part is an im-
