Section 32. Cession during use for purposes thereof, with sundry reservations

Title and jurisdiction to the following tract  or  parcel

  purposes  for  which  such  cession  is  made, from operating within the
  bounds of such tract; and that the United  States  are  to  retain  such
  jurisdiction  so  long  only as such tract shall be used for the defense
