   - summary: Unfortunately for the timber owner who wishes to enter upon extensive seeding operations, the business of collecting and preparing forest tree seed for market has received but little attention from old-established seed firms, and it is not always possible to purchase the species and quantity desired. On the other hand, forest fires in Montana, Idaho, Washington, Oregon and California destroy annually, on an average, timber which if used instead of destroyed would bring forty million dollars to their inhabitants, Idleness of burned and cut-over land represents a direct loss almost as great.

    - summary: How trees grow 3 Food materials and conditions of growth 3 Soil conditions 4 Light conditions 6 Physiology of tree growth 9 Sap up and sap down 10 Progress of development 11 Growth in length and ramification 11 Growth in thickness 14 Form development 17 Rate of growth 19 Reproduction 21 How to plant a forest 22 This process of food preparation, called assimilation, can be carried on only in the green parts, and in these only when exposed to light and air; hence foliage, air, and light at the top are essential prerequisites for tree growth, and hence, other conditions being favorable, the more foliage and the better developed it is, and the more light this foliage has at its disposal for its work, the more vigorously will the tree grow.
