No one would be the better for such a consummation as that. Now, if I retained my secret, and used it with wisdom, I might make myself the greatest benefactor to mankind that has ever lived. Those were the chief reasons, and I trust that they are not dishonourable ones, which led me to form the resolution, which I have today for the first time broken."
"But your secret is safe with me," cried Robert. "My lips shall be sealed until I have your permission to speak."
"If I had not known that I could trust you I should have withheld it from your knowledge. And now, my dear Robert, theory is very weak work, and practice is infinitely more interesting. I have given you more than enough of the first. If you will be good enough to accompany me to the laboratory I shall give you a little of the latter."
CHAPTER XI.
A CHEMICAL DEMONSTRATION.
Raffles Haw led the way through the front door, and crossing over the gravelled drive pushed open the outer door of the laboratory--the same through which the McIntyres had seen the packages conveyed from the waggon. On passing through it Robert found that they were not really within the building, but merely in a large bare ante-chamber, around the walls of which were stacked the very objects which had aroused his curiosity and his father's speculations. All mystery had gone from them now, however, for while some were still wrapped in their sackcloth coverings, others had been undone, and revealed themselves as great pigs of lead.
"There is my raw material," said Raffles Haw carelessly, nodding at the heap. "Every Saturday I have a waggon-load sent up, which serves me for a week, but we shall need to work double tides when Laura and I are married, and we get our great schemes under way. I have to be very careful about the quality of the lead, for, of course, every impurity is reproduced in the gold."
A heavy iron door led into the inner chamber. Haw unlocked it, but only to disclose a second one about five feet further on.
"This flooring is all disconnected at night," he remarked. "I have no doubt that there is a good deal of gossip in the servants'-hall about this sealed chamber, so I have to guard myself against some inquisitive ostler or too adventurous butler."
The inner door admitted them into the laboratory, a high, bare, whitewashed room with a glass roof. At one end was the furnace and boiler, the iron mouth of which was closed, though the fierce red light beat through the cracks, and a dull roar sounded through the building. On either side innumerable huge Leyden jars stood ranged in rows, tier topping tier, while above them were columns of Voltaic cells. Robert's eyes, as he glanced around, lit on vast wheels, complicated networks of wire, stands, test-tubes, coloured bottles, graduated glasses, Bunsen burners, porcelain insulators, and all the varied _debris_ of a chemical and electrical workshop.
"Come across here," said Raffles Haw, picking his way among the heaps of metal, the coke, the packing-cases, and the carboys of acid. "Yours is the first foot except my own which has ever penetrated to this room since the workmen left it. My servants carry the lead into the ante-room, but come no further. The furnace can be cleaned and stoked from without. I employ a fellow to do nothing else. Now take a look in here."
He threw open a door on the further side, and motioned to the young artist to enter. The latter stood silent with one foot over the threshold, staring in amazement around him. The room, which may have been some thirty feet square, was paved and walled with gold. Great brick-shaped ingots, closely packed, covered the whole floor, while on every side they were reared up in compact barriers to the very ceiling. The single electric lamp which lighted the windowless chamber struck a dull, murky, yellow light from the vast piles of precious metal, and gleamed ruddily upon the golden floor.
"This is my treasure house," remarked the owner. "You see that I have rather an accumulation just now.
