“I will. But first you go in and stay with mother. You can sleep here to-night if you wish, and to-morrow I will ask my father what can be done.”
He knocked at the door, but without waiting for his mother to come, ran up the second flight of stairs and reached out for the first board of the rude staircase. When he had found it he managed the ascent by clinging to the rail at the side, for the steps here were much steeper than those below; indeed in the dark it seemed to him a dizzy bit of a climb, but he managed it nimbly and found when he reached the landing that he could just peep in through one corner of the opened window shutter. Had the shutter been closed, as it usually was, he could have seen nothing, for the glass, consisting of little round uneven blocks, was unglazed and set into a network of lead. Through the opening he peered, clinging to the railing of the stairs for support, and keeping one foot close to the top step, in order to descend in haste at the first hint that the occupants of the room were aware of the presence of a third person.
What he saw at first glance startled him, for the loft was literally blazing with light coming from oils burning in four copper braziers which hung from the ceiling. Above these braziers, to protect the roof from the heat, were layers of metal, one separated from the other so that an air current played between them and cooled them. A fifth brazier, not now alight, hung close to the window where Joseph was peering, and it was from this brazier that the flame had sprung that had lighted up the whole court—as a matter of fact, the light had come from the rapid combustion of a handful of powder which the alchemist had thrown on the brazier’s charcoal.
The loft itself was higher than the boy had realized—there was but one large room in it, for on the farther side could be seen the shutters of the building’s outer wall. In the middle of the room at the back was a closet—for Pan Kreutz’s most valuable substances, Joseph decided, since it was fastened with chains as well as with a huge lock and key. The beams of the roof, sloping but slightly, were well above the height of a tall man, and were not of bare wood as is common in lofts and attics, but were plastered over with some thick white substance.
In the center of the room stood a tripod supporting an iron basin and in it was burning some substance that gave a peculiar, pungent odor.
The alchemist in his black robe and the student Tring in his leather jacket sat elbow to elbow before this basin. They were watching something that was burning there in flames of many colors.
“It takes away my strength,” Joseph heard the alchemist tell Tring, “to experiment in the fashion which you have suggested. It has interested me, and I know that it has its fascination, but it is not, after all, in my sphere. I am an alchemist, one who seeks the truth above all things in the actions and reactions of material substances. I mix vinegar and sugar and soda, and there is immediately a bubbling and a change. Something new is created. I melt lead and silver and copper, and they form together some metal that is new.”
“But are not these changes influenced also by the position of the stars in heaven?” asked Tring.
“Yes, and no. The sea, I admit, seems to follow the pull of the moon. Harvests depend upon seasons and seasons sometimes seem to be servants of the movements of the heavenly bodies. But as to other things I know not. Besides, I am not an astrologer. I am an alchemist. The powers of the sky may be found by those who search the skies.”
“But is not the conduct and life of man governed by the stars?”
