This is a book that will surely become beside reading for many generations to come. After the stress and strain of the work-a-day world what better refreshment for mind and spirit than tot have communion with the trees and learn something more of their mystery from a master of his craft? The Author’s lifelong dedication to the cause of the tree has been such as to absorb his whole being and it is, therefore, not surprising that in this, perhaps his greatest work, he should have written of his beloved trees in their Biblical and Classical settings as illustrative and expressive of the deepest mysteries and the highest qualities of the One Universal Life. The trees are a vital link between man and his Creator. The more he reacts rightly to the threes the more he grows in spiritual stature as well as material benefit. But if his reactions are those of ignorance and destruction—as has so often been the case throughout history—he brings himself to the very point of self-destruction. In the present parlous state of the world a new understanding of trees is vital to mankind, and a new attitude towards their culture essential to the preservation of life, on this planet. Not only are the various trees with which the earth is blest messengers of their Creator at the highest mystical level, but, like Himself they provide abundantly for all practical needs as well. Trees are a never-ending Joy and the Authors, whose Joy in them is abounding, pour out from the rich treasury of his knowledge and experience. The trees speak to us of Infinite Diversity and yet of Unity; of Strength; of Beauty; of adaptability from the most fertile to the most barren conditions of the earth. They provide, properly husbanded, materials for our shelter and our garmenting, and by their water-retaining power make all agriculture possible. Lastly, they are responsible for the very air we breathe without which we should have no existence at all.
