The diluted pulp isconveyed by gravity through two sets ofscreens, passing thence in a steady flow tostorage tanks in the machine room. In the machine room there are eighteen84-inch wet machines.

The grinder room is situated in thenorthern part of the main pulp grinders are in use, driven bywater-wheels. When the logs have beenreduced to the consistency of pulp, this isconveyed to a large concrete tank bymeans of gravity.
