This principle tells us why nature and society are so prodigal with treasures to some men and so niggardly to others. What a different thing a forest is to different men! He who gives the ax receives a mast. He who gives taste receives a picture. He who gives imagination receives a poem. He who gives faith hears the "goings of God in the tree-tops." The charcoal-burner fronts an oak for finding out how many cords of wood are in it, as the Goths of old fronted peerless temples for estimating how many huts they could quarry from the stately pile.[1] But an artist curses the woodsman for making the tree food for ax and saw. It has become to him as sacred as the cathedral within which he bares his head. It is a temple where birds praise God. It is a harp with endless music for the summer winds. It fills his eye with beauty and his ear with rustling melodies. For the poet that selfsame oak is enshrined in a thousand noble associations. It sings for him like a hymn; it shines like a vision; it suggests ships, storms and ocean battles; the spear of Launcelot, the forests of Arden; old baronial halls mellow with lights falling on oaken floors; King Arthur's banqueting chamber. To the scientist's thought the oak is a vital mechanism. By day and by night, the long summer through, it lifts tons of moisture and forces it into the wide-spreading branches, but without the rattle of huge engines. With what uproar and clang of iron hammers would stones be crushed that are dissolved noiselessly by the rootlets and recomposed in stems and boughs! What a vast laboratory is here, every root and leaf an expert chemist! For other multitudes the earth has become only a huge stable; its fruit fodder; its granaries ricks, out of which men-cattle feed. These estimate a man's value according as he has lifted his ax upon tall trees and ravaged all the loveliness of creation; whose curse is the Nebuchadnezzar curse, giving to nature the tongue and hand, and receiving from nature grass; who are doomed to love the corn they grind, to hear only the roar of the whirlwind and the crash of the hail, never "the still small voice;" who see what is written in lamp-black and lightning; who think the clouds are for rain, and know not that they are chariots, thrones and celestial highways; that the sunset means something else than sleep, and the morning suggests something other than work. All these give nature only thought for food, and food only shall they receive from nature, until all their deeds are plowed down in dust. Give forth thy gift, young men and maidens, and according as thou givest thou shalt receive fruit, or picture, or poem, or temple, or ladder let down from heaven, or angel aspirations going up.
