  on  and  over  the property and premises so conveyed, so far as that all
  civil and criminal process, which may issue under the laws or  authority
  of  the state of New York, may be executed thereon in the same manner as
  if such jurisdiction had not been ceded, except so far as  such  process
  may affect the real or personal property of the United States.
