Abstract
Abstract A liner adapted for insertion in an opening formed in ice on the surface of a body of water comprises a generally cylindrical body having at one end a peripheral flange. The body and the flange are slotted to enable the diameter of the body to be reduced for insertion in the opening, and the material from which the liner is made is sufficiently resilient to enable the body to expand into engagement with the side of the opening following insertion.
