The wood room processed all the wood required for the pulp and paper production. At one time the wood room also functioned as a lumber mill and could produce finished lumber. However, in the sixties, the wood room was only supplying wood for paper production. 
The logs were generally floated to Ocean Falls in log booms towed by tugboats. The mill itself had quite a few tugboats and boom boats so that the logs could be assembled and directed towards the jackladder. Later, large self-dumping barges were used to supply logs to the mill. The jackladder was a large conveyor with a spiked, continuous chain. The feed end of the conveyor was submerged in the ocean to permit the logs to be floated into the conveyor. This conveyor was vital to the mill operation since all the raw logs required had to be hauled up by this conveyor. It was not unusual that the head pulley down at the bottom in the water would jam. This could shut down the groundwood mill pretty quick and cause loss of production.

The logs would enter the sawmill and be cut to length by a large swing cut-off saw.  After the bark was removed in mechanical barkers the log would be cut into large slabs by a headrig. The headrig consisted of an enormous large band saw and a traveling carriage. The operator of the saw would be sitting on this carriage which also held the log.  The carriage would drive the log through the saw, the full length of the log to cut off a slab. The operator would then move the log closer to the saw blade for a second cut. Thus, the headrig operator was traveling sideways, left and right for hours on end at quite a good speed. 

The wood room would process the wood differently depending on which mill process the wood would be used in. Wood for the groundwood mill would be processed through gang saws which would reduce the slabs from the headrig into blocks. The long blocks would then be cut into short blocks by trim saws. The blocks thus created were transported to the groundwood mill through a very long water filled flume which ran along the backside of the mill in a long curve. Wood for the sulfite and  the sulphate mill was run through large  chippers in order to produce wood chips for these processes. The waste wood was collected by refuse conveyors and run through hammer hogs which would reduce all the wood to small size. This wood waste, also called hog fuel, was moved to storage piles and later reclaimed for combustion in power boilers. The hog fuel burned in the power boilers was an important part of the mills overall steam and electrical balance.
