DR. JOHN A. WARDER 
Dr. John A. Warder was an author of note, an authority upon American 
trees. His home was at North Bend, Ohio, some twenty miles from Cincin- 
nati, on the high bluff overlooking the Ohio River. 
His thorough investigation prompted him to visit the Wabash Valley and 
study the Catalpa tree in its home, and there discovered the wonderful char- 
acter of the tree which grew in this very restricted location, and gave it the 
name Catalpa speciosa. 
The subject of Forestry was one with which Dr. Warder was familiar, 
and he delivered numerous addresses upon the subject which proved him a 
man of great foresight, as he pointed out to the people of Ohio that in a very 
tew vears the forest would be gone from that State. 
Dr. Warder’s work on apples will ever be a standard authority,
