Section 14. Time of performing conditions of grant

1. The commissioner of
  general services may, unless otherwise provided, fix a reasonable  time,
  not  less  than  one  year,  for  the  performance  of conditions by the
  grantees of lands, including lands under water, directed to  be  granted
  on  the performance of conditions.  If such conditions are not performed
  within the time limited, the persons entitled to any benefit under  such
  grant  shall  forfeit  all  right  to  and title in the premises. If the
  commissioner, after having caused an inspection to be made of the  lands
  granted,  determines that the conditions contained in the letters-patent
  have been complied with, he may issue a certificate to that  effect.  If
  complete   compliance  has  not  been  had,  the  commissioner,  in  his
  discretion, may make an order to the effect that compliance had been had
  with the conditions  in  such  definitely  described  portion  of  lands
  granted  as  have been improved. Such order shall be conclusive evidence
  of the performance of the conditions contained in such letters-patent to
  the extent stated in such order and as to lands described therein.  When
  the  time  within  which any condition contained in any grant of land is
  fixed by the terms of the grant, the commissioner may,  for  good  cause
  shown  before  the expiration of such time, extend the time within which
  such condition is to be performed, not exceeding three years.
    2. The commissioner may, in his discretion, upon  application  of  the
  grantee  or  his successor in interest, by order, alter, amend or cancel
  any condition  or  conditions  contained  in  letters-patent  for  land,
  including  lands  under  water,  if  satisfied  by  the  reason or proof
  submitted that such alteration, amendment or cancellation  of  condition
  or  conditions  is  just  and is not detrimental to the interests of the
  state.
