Dear Dr. Simdell: 
Your letter of July 30th has just reached me 
as I am on the point of leaving for a vacation and 
have all my old field notes packed away. 
I shall try to answer your questions as soon 
as I get back and unpacked in September or October. 
Yours sincerely, 
Martin M. Moynfhan 
Director
