 Dear Dr. Muriae: 
 
           I an in receipt of your letters regarding 
 our conference in Chicago on ways and means of regu- 
 lating aircraft traffic in and over wilderness areas. 
 I have made a cursory check on this matter and dis- 
 cussed it wth somae well Inforned aeronautic author- 
 ities in this state. 
 
           There is no question in my mind but what 
reasonable regulations can be made and enforced by 
the authorities having Jurisdiction over the areas 
involved. Such rogulations would, of course, have to 
involve a reasonable exercise of police power and 
would include limitations as to landing, andminimum. 
altitude reouircments. Effective regulation on these 
two sublects would, of course, answer the question. 
The extent or intensity of regulation would have to 
vary with the area involved. 
 
           I am personally acquainted with the present 
Secretary of the Interior, .,r. Julius Krug, who ex- 
pects to be in Madison sometime tlis month. I shall 
try at that time to arrange for an opportunity to dis- 
cuss this subject with him in an effort to lay 'he 
groundwVor  for some study by his departmant of effect- 
ive future controls. 
 
                            Very trulv yours.
