lak(;est tree found in mis association 



Sycamore, buttonwood or plane tree (Plalanus occidentalis) near Worthington, Ind., l)y a big 

 margin the largest tree submitted in response to the American Genetic Association's 

 offer of prizes ff)r photographs. It is 42 feet 3 inches in circumference and about 140 

 feet high. Barring conifers, among which the California Sequoias defy comi)elition, the 

 sycamore probal)ly reaches a larger size than any other tree in M )rth America; and although 

 rejKjrts of I)iggcr trees are from lims.' to tim? mide, this ass')ciati()n has been unal>le to get 

 authentic record of any specimen which equals the Worthington tree in size. Its age is 

 unknown, but "oldest inhal)itants" declare it has not increased pzrceptibly in size in the 

 last sixty years. (Frontispiece.)
