 meteorological installations as are considered necessary for the 

 defense of the area. This grant included the right to do any and 

 all things necessary to insure the efficient operation, maintenance, 

 and protection of the facilities and fortifications installed. 



Denmark retained sovereignty over all deiense areas leased by 

 the United States, but the latter has jurisdiction over such areas 

 and the persons therein for as "long as this agreement shall remain 

 in force." This agreement remains in force "until it is agreed

 authorized by law, continue to collaborate for peacetime joint se-
