§ 2. I have been led to see and feel this more and more, as I considered the service which the flowers and trees, which man was at first appointed to keep, were intended to render to him in return for his care; and the services they still render to him, as far as he allows their influence, or fulfils his own task towards them. For what infinite wonderfulness there is in this vegetation, considered, as indeed it is, as the means by which the earth becomes the companion of man--his friend and his teacher! In the conditions which we have traced in its rocks, there could only be seen preparation for his existence;--the characters which enable him to live on it safely, and to work with it easily--in all these it has been inanimate and passive; but vegetation is to it as an imperfect soul, given to meet the soul of man. The earth in its depths must remain dead and cold, incapable except of slow crystalline change; but at its surface, which human beings look upon and deal with, it ministers to them through a veil of strange intermediate being; which breathes, but has no voice; moves, but cannot leave its appointed place; passes through life without consciousness, to death without bitterness; wears the beauty of youth, without its passion; and declines to the weakness of age, without its regret. § 3. And in this mystery of intermediate being, entirely subordinate to us, with which we can deal as we choose, having just the greater power as we have the less responsibility for our treatment of the unsuffering creature, most of the pleasures which we need from the external world are gathered, and most of the lessons we need are written, all kinds of precious grace and teaching being united in this link between the Earth and Man: wonderful in universal adaptation to his need, desire, and discipline; God's daily preparation of the earth for him, with beautiful means of life. First a carpet to make it soft for him; then, a colored fantasy of embroidery thereon; then, tall spreading of foliage to shade him from sunheat, and shade also the fallen rain, that it may not dry quickly back into the clouds, but stay to nourish the springs among the moss. Stout wood to bear this leafage: easily to be cut, yet tough and light, to make houses for him, or instruments (lance-shaft, or plough-handle, according to his temper); useless it had been, if harder; useless, if less fibrous; useless, if less elastic. Winter comes, and the shade of leafage falls away, to let the sun warm the earth; the strong boughs remain, breaking the strength of winter winds. The seeds which are to prolong the race, innumerable according to the need, are made beautiful and palatable, varied into infinitude of appeal to the fancy of man, or provision for his service: cold juice, or glowing spice, or balm, or incense, softening oil, preserving resin, medicine of styptic, febrifuge, or lulling charm: and all these presented in forms of endless change.
