or well marked varieties of oaks can here be found in a half mile walk. 

 All the identification of the trees listed have been verified by Professor 

 Sargent, and specimens of most of them are in the Arnold Arboretum, 

 collected mostly by myself, a few by Professor Sargent himself, who 

 visited the region in the spring of 1916, and a few by Mr. Harbison. There 

 is a full set in the herbarium of Tulanc University.
