Dear Mr. Morrow: Following your visit to me the other day I had a long talk with Secretary Dulles about the Ambassadorial post in Mexico.1
As of this moment, there are no specific plans for supplanting Mr. White in that post.2 On the other hand, it is a fact that as a general proposition we prefer to avoid keeping any individual in any Ambassadorial post for longer than four years.
With respect to a possible successor, the State Department is no longer concerned as to the State in which an appointee might have his residence.3 They are, however, convinced that the next man selected for the Mexican post, whenever such a change may be made, should have had extensive State Department experience. Supporting this decision are sound reasons with which I agree and which I am sure would be persuasive to you.
I know that this will be personally disappointing to you, but I assure you that neither in the Secretary's judgment nor in mine does it reflect in any way upon your own personal qualities and abilities, all of which we much admire and respect. I regret that I cannot send you a more encouraging letter.
Incidentally, while I was dictating this, your letter of March fourth reached my desk. Certainly I agree with you that merely because an individual claims Texas as his native State, it presents no disqualification for this particular post.4
With warm personal regard, Sincerely
