Pinus Banksiana at the West. 



By E. J. Hill. 



In the Bulletin for November, 1889, are two articles on 

 the presence of Pinus Banksiana, Lamb., on the coast of Maine, 

 and the impression left by reading the article is, that this station 

 is farther south than any yet reported. In " Garden and Forest " 



A 



southern locality is made in Professor Sargent's '* Report on the 

 Forests of North America," in one of the volumes of the tenth 

 census, and is quoted in one of the articles. But it is evidently 

 misunderstood, and may be slightly misleading to a casual reader. 

 It is reported as found on " the southern shore of Lake

Michigan, which, in its northern 



This may be taken for a part of the southern peninsula of 



part, extends eastward from 

 Grand Traverse Bay, the lower end of Lake Michigan having an 

 easterly trend for some distance. But if we substitute for this 

 statement ''shore of the south end of Lake Michi 

 to mistake is removed, and a locality is named considerably 

 further south than that at Frenchman's Bay in Maine. Thinking 

 a detailed account of the distribution of this pine may be of in- 

 terest to botanists and worth recording, I have compiled this ar- 

 ticle from my notes and observations and from other available 

 sources regarding its presence west of Lake Huron. 



To begin with the locahty nearest to Chicago, that at the 

 south end of Lake Michigan, we have one in latitude 41° 35', or 

 nearly two hundred miles south of that in Maine, and the most 

 southerly of any yet named, as far as I can learn. This is in the 

 counties of Lake and Porter, Indiana. I know of no other locali- 

 ties where it could be expected to occur, unless it be the next 

 two counties south, Newton and Jasper, where there is a similar 

 region of barren sand hills near the marshes of the Kankakee 



River, and around the head waters of the Iroquois. This was
