My dear Mr. President:
 
         I am attaching the third document of a secret
 
nature. You have received one on oils and raw materials;
 
 another on finances. The attached copy is on labor. They
 
 were all obtained under the same circumstances but have
 
 arrived at different times. The question of secrecy is of
 
 the essence, not so much because of the substance but
 
 because of the source. Consequently if you decide to
 
 make this document available to other persons, it is
 
hoped that you will impress upon themthe necessity
 
of abstaining from quotation from or allusion to the document.
 
                    Faithfully yours,
                                   Cordell Hull
     
 
Enclosure:
     Memorandum.
 
The President,
 
      The White House.
