This tree was formerly in much demand 

 for its shade; latterly (suffering from late 

 frosts, probably) it has fallen into disrepute 

 from its unhealthiness. I believe it carries 

 the disease with it even to other countries. 

 In landscape gardening it can only be em- 

 ployed effectively as a single specimen. It 

 does not harmonize well with other trees. 

 By itself, its magnificent proportions, its 

 broad-spreading habit and large ample foli- 

 age, challenge admiration. It will do well in 

 any situation, but prefers one inclining to 

 moisture. A specimen at Bartram is ninety- 

 five feet high and six feet in circumference. 

 May be propagated from seed sown as soon 

 as ripe* in a moist yet light soil, covering 



* Emerson recommends to soak the seed twenty-four 

 hours before sowing in the spring.
