I have sometimes tried to recall in imagination the world of Nature before a human voice had broken the silence or a human foot left its impress on the soil; but when I remember that what I see in this sweep of force and beauty is largely what I myself put into the vision, that Nature without the human ear is soundless, and without the human eye colourless, I understand that what lies spread before me never was until a human soul confronted it and became its interpreter. This radiant world upon which I look was without form and void until the earliest man brought to the vision of it that creative power within himself which touched it with form and colour and relations not its own. Nature is as incomplete and helpless without man as man would be without Nature. He brought her varied and inexhaustible beauty, and clothed her with a garment woven on we know not what looms of divine energy; and she fed, sheltered, and strengthened him for the life which lay before him. Together they have wrought from the first hour, and civilisation, with all the circle of its arts, is their joint handiwork. In the atmosphere of our rich modern fellowship with Nature, the unwritten poetry to which every open heart falls heir, we forget our earliest dependence on the great mother and the lessons she taught when men gathered about her knee in the childhood of the world. Not a spade turned the soil, not an axe felled a tree, not a path was made through the forest, that did not leave, in the man whose arm put forth the toil, some moral quality. In the obstacles which she placed in their pathway, in the difficulties with which she surrounded their life, the wise mother taught her children all the lessons which were to make them great. It was no easy familiarity which she offered them, no careless bestowal of bounty upon dependents; she met them as men, and offered them a perpetual alliance upon such terms as great and equal sovereigns proffer and accept. She gave much, but she asked even more than she offered, and in the first moment of intercourse she struck in men that lofty note of sovereignty which has never ceased to thrill the race with mysterious tones of power and prophecy. Men have stood erect and fearless in the presence of the most awful revelations of the forces of Nature, affirming by their very attitude a supremacy of spirit which no preponderance of power can overshadow. Face to face through all his history man has stood with Nature, and to each generation she has opened some new page of her inexhaustible story. Beginning in the hardest toil for the most material rewards, this fellowship has steadily added one province of knowledge and intimacy after another, until it has become inclusive of the most delicate and hidden recesses of character as well as those which are obvious and primary. In response to spirits which have continually come into a closer contact with her life, Nature has added to her gifts of food and wine, poetry
