To the plow are attached fans.

Only an inch or two of snow is left on the ground by this plow, which is followed by another special plow to gouge the ruts, and by a gang of "road monkeys" who clear the road thoroly.

Then follows an immense tank set on runners and holding perhaps seventy-five barrels of water, and so arranged as to flood the road from holes in the bottom of the tank, a sort of rough road sprinkler, Fig.10.The sprinkler goes over the road again and again until the road is covered by a clear, solid sheet of ice often two feet thick, extending from the skidways to the banking grounds.

This ice road is one of the modern improvements in logging.

Once finished, these roads are beautiful pieces of construction with deep, clear ruts.
