He had put on a stone-cloth shirt, and seizing iron pincers, he lifted off an iron cover. This allowed one to see four similar melting pots, each containing a fluid mass, one vermilion red, others lighter but all ruddy.
"Is that gold?" queried the prelate in an undertone, as if afraid by loud speaking to injure the mystery in progress.
"Yes, the four crucibles contain the metal in different stages of production, some having been on eleven hours, some twelve. The mixture is to be thrown into the first mass of ingredients—the living stuff into the gross—at the moment of boiling—that is the secret, which I do not mind communicating to a friend of the science. But, as your eminence may notice, the first crucible is turning white hot; it is time to draw the charge. Will you please stand well back, my lord?"
Rohan obeyed with the same punctuality as a soldier obeying his captain. Dropping the iron pincers, which had already heated to redness, the other ran up to the furnace a carriage on wheels of the same level, the top being an iron block, in which were set eight molds of round shape and the same capacity.
"This is the mold in which I cast the ingots," explained the alchemist.
On the floor he spread a lot of wet oakum wads to prevent the splashing of the metal setting the floor afire. He placed himself between the molds and the furnace, opened a large book, from which he read an incantation, and said, as he caught up long tongs in his hand to clutch the crucible:
"The gold will be splendid, my lord, of the first quality."
"Oh, you are never going to lift that mass single-handed?" exclaimed the spectator.
"Though it weighs fifty pounds, yes, my lord; but do not fear, for few metal-melters have my strength and skill."
