265 - Ice cutting and ice bridges.

  265.  Ice  cutting and ice bridges. A person or corporation cutting
  ice in or upon any waters within the boundaries of this  state  for  the
  purpose  of removing the ice for sale or use, must surround the cuttings
  and openings made with fences or guards  of  boards  or  other  material
  sufficient to form an obstruction to the free passage of persons through
  such  fences  or guards into the place where such ice is being cut. Such
  fences or guards must be erected at or before the time of commencing the
  cuttings or openings, and must be maintained until ice has again  formed
  therein  to  the  thickness  of  at least three inches, or until the ice
  about such openings has melted or broken up.  Whoever  omits  to  comply
  with this section is guilty of a misdemeanor.
