"Command me. Why not begin at once? What apparatus or chemical agencies do you need?" "Ah!" said Margrave, "formerly, how I was misled! Formerly, how my conjectures blundered! I thought, when I asked you to give a month to the experiment I wish to make, that I should need the subtlest skill of the chemist. I then believed, with Van Helmont, that the principle of life is a gas, and that the secret was but in the mode by which the gas might be rightly administered. But now all that I need is contained in this coffer, save one very simple material,--fuel sufficient for a steady fire for six hours. I see even that is at hand, piled up in your outhouse. And now for the substance itself,--to that you must guide me." "Explain." "Near this very spot is there not gold--in mines yet undiscovered?--and gold of the purest metal?" "There is. What then? Do you, with the alchemists, blend in one discovery gold and life?" "No. But it is only where the chemistry of earth or of man produces gold, that the substance from which the great pabulum of life is extracted by ferment can be found. Possibly, in the attempts at that transmutation of metals, which I think your own great chemist, Sir Humphry Davy, allowed might be possible, but held not to be worth the cost of the process,--possibly, in those attempts, some scanty grains of this substance were found by the alchemists, in the crucible, with grains of the metal as niggardly yielded by pitiful mimicry of Nature's stupendous laboratory; and from such grains enough of the essence might, perhaps, have been drawn forth, to add a few years of existence to some feeble graybeard,--granting, what rests on no proofs, that some of the alchemists reached an age rarely given to man. But it is not in the miserly crucible, it is in the matrix of Nature herself, that we must seek in prolific abundance Nature's grand principle,--life. As the loadstone is rife with the magnetic virtue, as amber contains the electric, so in this substance, to which we yet want a name, is found the bright life-giving fluid. In the old goldmines of Asia and Europe the substance exists, but can rarely be met with. The soil for its nutriment may there be well-nigh exhausted. It is here, where Nature herself is all vital with youth, that the nutriment of youth must be sought. Near this spot is gold; guide me to it." "You cannot come with me. The place which I know as auriferous is some miles distant, the way rugged. You can not walk to it. It is true I have horses, but--" "Do you think I have come this distance and not foreseen and forestalled all that I want for my object? Trouble your self not with conjectures how I can arrive at the place. I have provided the means to arrive at and leave it. My litter and its bearers are in reach of my call. Give me your arm to the rising ground, fifty yards from your door."
