 to the Township of Tuckersmith, Huron Co., it is really only found 

 plentiful and in perfection in what may be called the Lake Erie 

 District, where, with the black walnut, it once formed the great bulk 

 of the forest. When covered with its large tulip-shaped blossoms, 

 about the first of July, it forms an object of beauty that once seen 

 can never be forgotten.

 Port Dover Junction {Macoun) Sandy soil, Windsor, Ont. {J. M.

 islands on the north side of Lake Erie, he not having seen the 

 specimens.
