to be effected by squirrels and otber animals, but why these animal* 

 should not iu time have established the trees on new soils is difficult 

 to explain, unless sandy soils exert some favorable influence, lack- 

 ing in other soils, on the germination of the seeds. Some indica- 

 tions of a prevalence of other species on certain geological forma- 

 tions are to be detected, but when the distribution thruout the 

 State and outside our limits is considered one is led to refer most 

 of these cases to other influences than those coming from mineral 

 constituents of the soils. 



Yew Family Taxaceae). 



? Ground Hemlock, American Few, — ThiB 



bushy evergreen is given in M'Murtrie's list, but Short and Peter 

 omit it. Dr. Gattinger, also, does not include the specie? in his 

 "Tennessee Flora." In John Hi. 1st of Barren and Edmon- 



son County plant.- it reappears under the name u Taru» baccata, var. 

 canadensis," but the author says nothing about it in his discussion 

 of the evergreens observed by him. Gr the distribution 



as extending from Newfoundland to Virginia, and, at the north, 

 westward to Iowa and Manitoba. The author of this list is familiar 

 with the plant as it occurs in northern Michigan. He has botanized 

 repeatedlv in Barren and Edmonson counties and has never ob- 

 served it there. It is doubtful if it can be considered a native of 

 this State, but attention is called to it in the hope of getting further 

 information. The leaves are green on both sides, in which respect 

 it differs from young growth of the common hemlock. Its fruit 

 is a red berry instead of a cone. 



Pine Family Pinaceae). 



White Pine (Pinus strobus). — A beautiful evergreen, produc- 

 ing a splendid, white, soft, easily-worked wood. Some very good 

 trees, two feet in diameter of trunk and sixty feet or more high, were 

 noted seventeen years ago at Torrent in Wolfe County. Young 

 trees are still not uncommon. The tree is well adapted to parks 

 and lawns.
