  (1) A license under section3 shall, unless
  
  revoked earlier, continue in force for a period of three years from the dare on
  
  which it is granted:
  Provided
  
  
  
  that such
  
  a license may be granted for a shorter period if the person by whom the license
  
  is required so desires or if the licensing authority for reasons to be recorded
  
  in writing considers in any case that the license should be granted for a
  
  shorter period.
  (2) A license under any other provision of
  
  Chapter II shall, unless revoked earlier, continue in force for such period
  
  from the dare on which it is granted as the licensing authority may in each
  
  case determine.
  (3) Every license shall, unless the licensing
  
  authority for reasons to be recorded in writing otherwise decides in any case,
  
  be renewable for the same period for which the license was originally granted
  
  and shall be so renewable from time to time, and the provisions of section 13
  
  and 14 shall apply to the renewal of a license as they apply to the grant
  
  thereof.
