CHAPTER III FORESTS Aside from the soil itself, which supports all life, there is no other resource so important to man as the forests, with their many uses covering so wide a range. The beauty and restfulness of a forest, the grace and dignity of single trees, the shade for man and animals, the shelter from storms--all these things appeal to our love for the beautiful, and touch our higher nature. The person who loves trees is a better person than the one who does not. As the poet expresses it: "Ah, bare must be the shadeless ways, and bleak the path must be, Of him, who, having open eyes, has never learned do see, And so has never learned to love the beauty of a tree. "Who loves a tree, he loves the life that springs in star and clod, He loves the love that gilds the clouds, and greens the April sod, He loves the wide Beneficence; his soul takes hold on God." Trees have played an important part in the history of our country: The "Charter Oak," in the hollow of which the original charter of Connecticut remained hidden from the agents of the king; "Eliot's Oak," under which the gospel was first preached to the Indians; the wide-spreading elm under which William Penn signed his treaty of peace with the Indians.
