ECOLOGY OF NORTHERN MICHIGAN. 131 



of which was an old ore bucket into which they had apparently fallen and 

 drowned. Farther south these animals are closely confined to swamp land. 

 24. My otis subulatus (Say). Say's Bat. II. 3. Three adult males 

 were taken in camp, August 13, by Peet. 



Supplementary Notes. 



The following notes were secured by Mr. Wood from Mr. C. E. Haring 

 of Ontonagon, Michigan. Mr. Haring and his brother bought furs from the 

 Indians and trappers between 1860 and 1875. Unless otherwise specified 

 these records refer to Ontonagon County. 



Caribou. He had no authentic record of this species. 



Moose (Alee). A moose was taken at Union Bay in 1864, and one at 

 Gogebic Lake, Gogebic County in 1863. 



Deer. Are more abundant now than formerly. 



Beaver. Was yet common in 1860. 



Canada Lynx. Was twice as abundant as the Wild Cat. At the present 

 time this species is rare. 



Wild Cat. Common. 



Panther. Had no experience with them but had heard authentic reports 

 of their occurrence before 1860. 



Wolf. Was very common and killed many deer. 



Red Fox. Was common; cross fox rare, and silver gray fox very rare. 



Otter. Several skins were secured each year about 1860. 



Wolverine. At Rockland, five were bought by his brother, J. M. Haring, 

 between 1865 and 1875. This is the only Michigan (?) locality known to 

 the writer. Of course the animals may not have been killed near Rockland, 

 but may have come from a distance. Hon. Peter White, of Marquette, 

 informs me, that, although he has made inquiry for many years, he has been 

 unable to obtain authentic records of the Wolverine in Michigan. 



Fisher. Common in 1860; a few skins secured each year. 



Martin. Very common in 1860. A few have been taken in recent years. 



Mink. Common. 



Racoon. A very few have been taken. 



2. ISLE ROYALE. 



1. Rangifer caribou (Gmelin). Woodland Caribou. An Indian trapper 

 reported that fresh tracks were seen during July, 1904, in a clearing near 

 Siskowit Bay. 



2. Sciurus hudsonicus Erx. Hudson Bay Red Squirrel. II. Nine 

 specimens were taken in the coniferous forests, both young and adults. 

 The resin on the hair about the mouth shows that both young and adults 

 feed upon the coniferous seeds. Two of the specimens are old females 

 which have reared young, as shown by the scanty hair on the belly; in both, 

 four nipples had been functional. III. A young and adult male were taken 

 in the deciduous forest along the Lake Desor trail. 



There is considerable variation in the color of the upper side of the tail 

 in the Isle Royale specimens. The median rufous band is quite pronounced 

 in two specimens. 



A' winter skin, taken by a trapper, lacks the distinct lateral black line, 

 found in the summer specimens and has a faint rufous stripe extending 

 from the ears to the subterminal black bar on the tail. The shorter tails, with
