 Tilia Americana, L. (American Linden. Basswood.) A fine 

 shade tree scattered through the county, seldom more than a few 

 trees being seen together. It is subject to the "attacks of insects, the 

 leaves by mid-summer often being quite unsightly, owing to their 

 almost skeletonized appearance. Mr. J. H. Sears, of Danvers, to 

 whom the writer will frequently have occasion to refer in these notes, 

 gives the following measurements of a Basswood which, in 1867, grew 

 in Danvers, beside a never-failing spring. 



Circumference 12 feet 3 inches at 1 foot from gi-ound

Tilia Europ.ea. (European Linden.) Much used as a street
