secret of vegetable nature; he watches the slow life of plants; he notes the parity of motion among all the species, and the parity of their nutrition; he finds everywhere the need of sun and air and water, to fecundate and nourish them. Another scrutinizes the blood of animals. A third studies the laws of universal motion and its connection with celestial revolutions. Nearly all are eager to struggle with the intractable nature of metal, for while we find many principles in other things, we find all metals like unto themselves in every particular. Hence a common error as to our work. Behold these patient, indefatigable athletes, ever vanquished, yet ever returning to the combat! Humanity, sire, is behind us, as the huntsman is behind your hounds. She cries to us: ‘Make haste! neglect nothing! sacrifice all, even a man, ye who sacrifice yourselves! Hasten! hasten! Beat down the arms of DEATH, mine enemy!’ Yes, sire, we are inspired by a hope which involves the happiness of all coming generations. We have buried many men--and what men!--dying of this Search. Setting foot in this career we cannot work for ourselves; we may die without discovering the Secret; and our death is that of those who do not believe in another life; it is this life that we have sought, and failed to perpetuate. We are glorious martyrs; we have the welfare of the race at heart; we have failed but we live again in our successors. As we go through this existence we discover secrets with which we endow the liberal and the mechanical arts. From our furnaces gleam lights which illumine industrial enterprises, and perfect them. Gunpowder issued from our alembics; nay, we have mastered the lightning. In our persistent vigils lie political revolutions.” “Can this be true?” cried the king, springing once more from his chair.
