Mrs. Alex Wetmore, 
1823 Massachusetts Street, 
Lawrence, Kansas. 
My dear Mrs. Wetmore: 
During Dr. Wetmore*s absence all letter mail 
directed to him and not obviously official in character 
will be forwarded to you unopened. It is probable that 
certain official letters under stamp will reach you and 
these, of course, should be returned for prompt attention 
by this Bureau. A dozen franked envelopes are being 
sent you for your use in this connection. 
With best wishes, I am. 
Very truly yours. 
Chief of Bureau
