Along the northwest shore of Bluffy lake and at the fallsbelow its outlet, the gneiss is of a more granitoid type, grey in colour, witJiinclusions showing evidence of having been partly fused and recrystallized. Onthe fourth small lake-expansion (Brule lake) of White Mud river, at the soutliend,.the granite gneiss is again replaced by soda-rhyolite gneiss Avith granitoidapophyses at intervals parallel to the lamination. It is quite possible that therhyolite occupies the whole district between this point and Lac Seul. On thenorth shore of the same small lake there is a band of hornblende-magnetite schistvery similar in composi
