3. Informational and Related Matter Pertaining to Woodwork and Mechanical Drawing. Closely related to any subject is a vast fund of informational matter. If the student is to have an intelligent understanding of the subject matter, he must be given opportunity to become acquainted with at least the most important of this related information.

In the seventh grade the necessary study of tools and processes occupies the pupil's time fully. In the eighth grade opportunity offers itself for introducing such subjects as wood structure, tree growth, lumbering, and milling. In high school, the pupil should be made familiar with the most common woods, their classification, characteristics, and uses.

High school pupils should be assigned outside readings on forestry. They should secure and classify specimens of the more common woods and should be able to recognize the tree by leaf, fruit, bark, wood and tree form. See Figs. 4, 5, and 6.

In the grammar grades, mounted specimens should be prepared illustrative of tree structure, shrinkage, defects, etc. As in the high school, pupils should be encouraged to seek and prepare specimens illustrative of the subjects under consideration.

It is now possible to rent or purchase very excellent lantern slides on forestry, lumbering, milling, etc. Add the use of these to that of the mounted specimens if at all possible.

The detailed lesson outlines indicate definitely where these subjects are to be given attention in the course. The pages of the text are also indicated. The high school library should be provided with the very excellent bulletins of the United States Department of Agriculture, Division of Forestry, most of which are for free distribution.
