This defect in the hemlock reduces its market value to about one-half that of the spruce for paper making.

Some of the paper mills in British Columbia are now using these species of pulpwood and report that they make high-grade paper.
The pulp logs are floated down to the paper mill.

In the mill the bark is removed from the logs.

Special knives remove all the knots and cut the logs into pieces twelve inches long and six inches thick.

These sticks then pass into a powerful grinding machine which tears them into small chips.
