CANADA LUMBERMAN id The Purpose and Plan of Forestry Work *By C. D. HOWE, Dean of Faculty of Forestry, University of Toronto. Dr. C. D. Howe, Toronto. As I understand it, the primary object of forestry is the produc- tion of wood of a certain quan- tity and of a certain quality un- der certain given climatic and soil conditions. The material which we call wood is a certain chemi- cal substance produced in large quantities only by certain types of plants which we call trees. If the chief object of a forester is the production of wood, then it goes without saying, that he must understand how wood is produced in nature, that is, he must under- stand the physiological relation- ships of trees: how they manufac- ture their food, how they digest h ir food, how they assimilate the digested food and transform it into wood. Now, we know that certain things external to the tree influence its wood produc- tion. These are particularly the climate and the soil. In order to produce the largest quantity of the most desirable quality of wood, the forester must understand how trees are influenced in their growth by the climatic and soil factors, that is, he must understand the biological relationships of trees. While a forester must undertsand the life relationships of indi- vidual trees, I believe that, in order to be sucessful in his work of producing wood, he must acquire a broader conception of forest life. He deals not with single trees alone, but with tree aggregates, with tree communities. These tree communities, like communities of humans, have their mutual relationships, their dependencies, and their interde- pendences And like other living communities, they have their stratifi- cations, their laws of reproduction, development and decay; their laws of progression and of retrogression. By this I mean to say that in order to do his best
