Section 17. Heirs of patriotic Indian

The heirs of an Indian to whom real
  property was granted for military services rendered during  the  war  of
  the  Revolution  may  take  and hold such real property by descent as if
  they were citizens of the state at  the  time  of  the  death  of  their
  ancestors.  A  conveyance  of  such  real  property to a citizen of this
  state, executed by  such  Indian  or  his  heirs  after  March  seventh,
  eighteen  hundred  and  nine, is valid, if executed with the approval of
  the surveyor-general or state engineer and  surveyor  prior  to  January
  first,  nineteen  hundred  and  twenty-seven,  and  thereafter  with the
  approval of the commissioner of transportation indorsed thereon.
