the property about forty years ago. Mount Pleasant is situated on 

 a hill, and on Second Avenue there is a trimmed osage orange hedge. 

 To the west of this enclosure there is an old barberry hedge and

 willow and Scotch pine. Adjacent to this hedge is the pasture, which 

 consists of various hardwood, bur oak, red oak, Carya ovata, Ulmus 

 Americana, U. fulva and some Catalpa kccmpfcri. There were also 

 some Samhucus canadensis, Ouerciis velutina, Tilia Americana, C elf is 

 occidentalis and Rubiis occidcntalis. 



Among the other plants observed in this pasture, mention may be 

 made of Eiipatorium urticccfolium, Hcdeoma pulegioides, Monarda 

 fstulosa, Verbena stricta, Arctium major, Verbena urticcefolia, 

 Solidago canadensis and 5". serotina, Brnnella vulgaris, Muhlenbergia
