"Not much; the sun is hot, and the glare so powerful that I am almost blind. What a pity it is that we had not some trees here, to shade us from the heat! I should like to plant some for the benefit of those who may come after us." "A correct feeling on your part, my boy; but no trees would grow here at present--there is no soil." "There is plenty of some sort or other in the part where we have been surveying." "Yes, the sand thrown up by the sea, and the particles of shells and rock, which have been triturated by the wave, or decomposed by the alternate action of the elements; but there is no vegetable matter, without which there can be no vegetable produce. Observe, Willy,--the skeleton of this earth is framed of rocks and mountains, which have been proudly rearing their heads into the clouds, or lying in dark majesty beneath the seas, since the creation of the world, when they were fixed by the Almighty architect, to remain till time shall be no more. Over them, we find the wrecks of a former world--once as beautiful, as thickly peopled, but more thoughtless and more wicked than the present, which was hurled into one general chaos, and its component, but incongruous parts, amalgamated in awful mockery by the deluge--that tremendous evidence of the wrath of Heaven. But it has long passed away; and o'er the relics of former creation, o'er the kneaded mass of man in his pride, of woman in her beauty, of arts in their splendour, of vice in her zenith, and of virtue in her tomb, we are standing upon another, teeming with life, and yielding forth her fruits in the season as before. But, Willy, the supports of life are not to be found in primeval rocks or antediluvial remains. It is from the superficial covering, the thin crust with which the earth is covered, composed of the remains of former existence, of the breccia of exhausted nature, that animal creation derives its support; and it is the grand axiom of the universe, that _animal life can only be supported by animal remains_. From the meanest insect that crawls upon the ground, to man in his perfection, life is supported and continued by animal and vegetable food; and it is only the decayed matter returned to the earth, which enables the lofty cedar to extend its boughs, or the lowly violet to exhale its perfume. This is a world of eternal reproduction and decay--one endless cycle of the living preying on the dead--a phoenix, yearly, daily, and hourly springing from its ashes, in renewed strength and beauty. The blade of grass, which shoots from the soil, flowers, casts its seed, and dies, to make room for its offspring, nourished by the relics of its parent, is a type of the never-changing law, controlling all nature, even to man himself, who must pass away to make room for the generation which is to come."
