While it maybe that a few of the species enumerated are not of them- 

 selves sufficient to stamp a region as Canadian, no locality outside 

 of this zone can have a fauna and a flora in which the mammals, birds 

 and plants of these three lists predominate. The period of plant 



1 These are mostly included among the plants found on the Adirondack league club tract. (Smith 

 '94 and '98).
