Of the stations given above, numbers XIV to XIX inclusive 

 have been designated in the list of species as the Snowbank 

 lake area, XX and XXI as Ely, VIII and IX as the ^lisquah 

 hills, and VI and VII as Gunflint. All other areas include 

 each but a single station. The quantity-collecting being largely 

 done when we left Grand Portage, we were able to move rapidly, 

 as only plants not found in this first area needed to be collected 

 in bulk. For illustration of distribution, the collections were 

 made as complete as possible at Grand Portage, Gunflint, in the 

 Misquah hills, at Tofte, at Beaver Bay and in the Snowbank 

 lake area. 



There is an appreciable difference between the lichen flora of 

 Grand Portage island and that of the mainland two miles across 

 the bay. The island reaches an elevation of onlv 125 feet above 

 lake Superior while Mt. Josephine on the mainland reaches an 

 altitude of about 800 feet above the lake. The Keweenawan 

 series of rocks, which appears on the island, is wanting on the 

 portion of the adjacent mainland explored, while the Animikie 

 series is found in both places. However, I could not ascertain 

 that difference in petrographical construction in any noticeable 

 wa\' determines the floral differences either here or elsewhere in 

 the territory studied. Passing b}^ the Gunflint area for the pres- 

 ent, I may say that the Misquah hills were regarded as especi- 

 ally Important, since they contain the highest areas in the state, 

 and were as carefully studied as our time would permit. Carl- 

 ton peak at Tofte, and the Palisades were points of special in- 

 terest. Two Harbors was of interest as it is the most southern 

 point reached in the surve}^ and Ely was, also, as it is the most 

 western. However, the Snowbank lake area somewhat further 

 east was much more thoroughly studied than Elv. 



On the whole all of the two counties was studied thoroughly 

 enough to know that practically all of the lichens generally dis- 

 tributed over the area were secured as well as manv more which
