408 THE CANADIAN NATURALIST. [Dec. 



the identity of some of these trees there can be no possibility of 

 error. I shall only here instance the basswood ( T'dia Americana)^ 

 and the red oak (^Qaerciis 7'ubra\ — trees not easily mistaken. 

 Entering Canada from Maine, the basswood is observed in the 

 counties of Arthabaska, Wolfe, and Nicolet, thence it ranges along 

 the St. Lawrence to the river Ottawa, and far up that stream, 

 through Argenteuil and Ottawa, to the Island of Alumette. Cross- 

 ing the country, it is met with in the townships of Richards, 

 Brunei, and Stephenson, and finally appears to take its leave of 

 Canada at Sturgeon Bay on Lake Huron. It re-appears on the 

 south shore of Lake Superior, and at Bainy Lake on the British 

 side, whence it extends to the Bed River, and northward to latitude 

 52^. A most remarkable locality is Lake St. John near its outlet 

 into the Saugenay, recorded by Professor Bell in the Geological 

 Survey Beport for 1857. The red oak, again, ranges from the 

 neighborhood of Quebec, where the variety Q. rubra var. borealis 

 is said by Cooper (Smithsonian Beports) to attain its north-eastern 

 limit, up to Montreal, and thence skirting the Ottawa, apparently 

 sparingly, it extends westward to Lake Huron ; on the north 

 shore of which, and on the Manitoulin Islands, where it is said to 

 attain considerable size, it is frequently observed. On the eastern 

 shores of Lake Superior, too, red oaks are met with ; but, accord- 

 ing to x^gassiz, Michipicoten Island forms in Canada the north- 

 western limit of distribution.
