TION OF SILVICULTURE TO THE KINDRED ARTS. OF 
AGRICULTURE, HORTICULTURE, AND LANDSCAPE GAR- 
DENING 
‘“The preservation of our forests is an imperative business 
necessity. We have come to see clearly that whatever destroys 
the forest, except to make way for agriculture, threatens our 
well-being.” —President Roosevelt.
