Kloos, J. H. Article in The Minnesota Teacher, referred to by N. H. 

 Winchell. 



Wincliell " says that Kloos suggests the possibility of the hematitic 

 and magnetitic iron ore at Vermilion Lake being in the lowest member of 

 the Huronian.

In this article (p. 199) Kloos states that he has become acquainted 

 with gneisses and finely crystalline clay slates from Vermilion Lake, which 

 appear to him to belong to the Laurentian. A small rush to this area was 

 caused by the discovery of gold-bearing pyritiferous quartz veins, cutting 

 the metamorphic schists, but did not result in the opening up of productive 

 mines. He farther on mentions having heard favorable reports concerning 

 the iron ores of Vermilion Lake.

This contains a report (pp. 92-94) of a reconnaissance along a part of 

 tlie international boundary from Gunflint Lake to Whitewood " (Basswood) 

 Lake, which is included in the Vermilion district. He observed sedimenta- 

 ries, slates, and dolomite associated with trap on Gunflint Lake. These he 

 correlated with the Lake Superior copper-bearing rocks. They are suc- 

 ceeded to the northwest by the Laurentian granite of Seiganagah (Saganaga) 

 Lake. West of this Laurentian area the route crosses from Poplar Lake 

 (Swamp Lake of the boundary commission map) to Whitewood (Basswood) 

 Lake, a belt of Huronian black to green and gray schists, slates, and 

 quartzites, cut by dikes of trap. The sediments strike S. 15°-30° W., and 

 dip about 80° W. The only rocks observed around the shores of White- 

 wood Lake are fine-grained gray to reddish-gray syenite.

'• The usual name given to this lake is Basswood. No basswood was seen by Bell about the lake, 

 however, and mj' own observation showed me that it is certainly not present in great quantity there. 

 He states that " the lake is said to derive its name Lac de Bois Blanc, or Whitewood Lake, from the 

 whitewood, or balm of Gilead, a kind of poplar" (p. 94).
