My dear Dr. Hicken: 
This letter will introduce to you Mr. 
Alexander Wetraore, who is carrying on some 
investigations in your country in behalf of 
the U. 3. Department of Agriculture. Any¬ 
thing that you can do to assist Mr. Wetmore 
will be very much appreciated by me. 
I had hoped to go to South America, my¬ 
self, this summer but at the very last was 
obliged to change my plans. I often recall 
the many courtesies which you extended to me 
when in South America a few years ago. 
Yery truly
