The legal machinery creating forestry extension as we know it today is indeed modern, yet in a strict application of the term, extension work in forestry may well be considered as antedating the whole agricultural extension idea. Even before Dr. Knapp inaugurated his remarkable system among the southern planters and agriculturists, of teaching by field demonstrations, the old Bureau of Forestry was carrying on activities far more along extension than administrative lines. But the reorganization of the Forestry Service in 1905 brought about a new order, and not until the passage of the Smith-Lever Act in 1914 were adequate plans laid for building up an efficient organization to be known as Extension Farm Forestry.
