         Dear Sir: 
 
                   This is to acknowledge the receipt of 
         your letter addressed to the lernbers of the Com- 
         mittee on Airplane Use in Relation to Wilderness 
         Areas.  l5r. Olmsted is at present in California, 
         in The Redwoods district, and I have forwarded 
         your letter to him.  However, as he is sometimes 
         out of touch with mail for several days at a time, 
         your letter may be delayed in reaching him. 
 
                   I am sending a copy of this acknowledgment 
          to Mr. Aldo Leopold, to Madison, Wisconsin. 
 
                              Very truly yours,
