CHAPTER X. THE GREAT SECRET.

And so Laura McIntyre became duly engaged to Raffles Haw, and old

McIntyre grew even more hungry-looking as he felt himself a step nearer

to the source of wealth, while Robert thought less of work than ever,

and never gave as much as a thought to the great canvas which still

stood, dust-covered, upon his easel. Haw gave Laura an engagement ring

of old gold, with a great blazing diamond bulging out of it. There was

little talk about the matter, however, for it was Haw's wish that all

should be done very quietly. Nearly all his evenings were spent at

Elmdene, where he and Laura would build up the most colossal schemes of

philanthropy for the future. With a map stretched out on the table in

front of them, these two young people would, as it were, hover over the

world, planning, devising, and improving.

“Bless the girl!” said old McIntyre to his son; “she speaks about it as

if she were born to millions. Maybe, when once she is married, she won't

be so ready to chuck her money into every mad scheme that her husband

can think of.”

“Laura is greatly changed,” Robert answered; “she has grown much more

serious in her ideas.”

“You wait a bit!” sniggered his father. “She is a good girl, is Laura,

and she knows what she is about. She's not a girl to let her old dad go

to the wall if she can set him right. It's a pretty state of things,” he

added bitterly: “here's my daughter going to marry a man who thinks no

more of gold than I used to of gun-metal; and here's my son going about

with all the money he cares to ask for to help every ne'er-do-well in

Staffordshire; and here's their father, who loved them and cared for

them, and brought them both up, without money enough very often to buy

a bottle of brandy. I don't know what your poor dear mother would have

thought of it.”

“You have only to ask for what you want.”

“Yes, as if I were a five-year-old child. But I tell you, Robert, I'll

have my rights, and if I can't get them one way I will another. I won't

be treated as if I were no one. And there's one thing: if I am to be

this man's pa-in-law, I'll want to know something about him and his

money first. We may be poor, but we are honest. I'll up to the Hall now,

and have it out with him.” He seized his hat and stick and made for the

door.

“No, no, father,” cried Robert, catching him by the sleeve. “You had

better leave the matter alone. Mr. Haw is a very sensitive man. He would

not like to be examined upon such a point. It might lead to a serious

quarrel. I beg that you will not go.”

“I am not to be put off for ever,” snarled the old man, who had been

drinking heavily. “I'll put my foot down now, once and for ever.” He

tugged at his sleeve to free himself from his son's grasp.

“At least you shall not go without Laura knowing. I will call her down,

and we shall have her opinion.”

“Oh, I don't want to have any scenes,” said McIntyre sulkily, relaxing

his efforts. He lived in dread of his daughter, and at his worst moments

the mention of her name would serve to restrain him.

“Besides,” said Robert, “I have not the slightest doubt that Raffles

Haw will see the necessity for giving us some sort of explanation before

matters go further. He must understand that we have some claim now to be

taken into his confidence.”

He had hardly spoken when there was a tap at the door, and the man of

whom they were speaking walked in.

“Good-morning, Mr. McIntyre,” said he. “Robert, would you mind stepping

up to the Hall with me? I want to have a little business chat.” He

looked serious, like a man who is carrying out something which he has

well weighed.

They walked up together with hardly a word on either side. Raffles Haw

was absorbed in his own thoughts. Robert felt expectant and nervous,

for he knew that something of importance lay before him. The winter had

almost passed now, and the first young shoots were beginning to peep out

timidly in the face of the wind and the rain of an English March. The

snows were gone, but the countryside looked bleaker and drearier, all

shrouded in the haze from the damp, sodden meadows.

“By the way, Robert,” said Raffles Haw suddenly, as they walked up the

Avenue. “Has your great Roman picture gone to London?”

“I have not finished it yet.”

“But I know that you are a quick worker. You must be nearly at the end

of it.”

“No, I am afraid that it has not advanced much since you saw it. For one

thing, the light has not been very good.”

Raffles Haw said nothing, but a pained expression flashed over his face.

When they reached the house he led the way through the museum. Two great

metal cases were lying on the floor.

“I have a small addition there to the gem collection,” he remarked as he

passed. “They only arrived last night, and I have not opened them yet,

but I am given to understand from the letters and invoices that there

are some fine specimens. We might arrange them this afternoon, if you

care to assist me. Let us go into the smoking-room now.”

He threw himself down into a settee, and motioned Robert into the

armchair in front of him.

“Light a cigar,” he said. “Press the spring if there is any refreshment

which you would like. Now, my dear Robert, confess to me in the first

place that you have often thought me mad.”

The charge was so direct and so true that the young artist hesitated,

hardly knowing how to answer.

“My dear boy, I do not blame you. It was the most natural thing in the

world. I should have looked upon anyone as a madman who had talked to me

as I have talked to you. But for all that, Robert, you were wrong, and I

have never yet in our conversations proposed any scheme which it was not

well within my power to carry out. I tell you in all sober earnest that

the amount of my income is limited only by my desire, and that all the

bankers and financiers combined could not furnish the sums which I can

put forward without an effort.”

“I have had ample proof of your immense wealth,” said Robert.

“And you are very naturally curious as to how that wealth was obtained.

Well, I can tell you one thing. The money is perfectly clean. I have

robbed no one, cheated no one, sweated no one, ground no one down in the

gaining of it. I can read your father's eye, Robert. I can see that he

has done me an injustice in this matter. Well, perhaps he is not to be

blamed. Perhaps I also might think uncharitable things if I were In his

place. But that is why I now give an explanation to you, Robert, and not

to him. You, at least, have trusted me, and you have a right, before I

become one of your family, to know all that I can tell you. Laura also

has trusted me, but I know well that she is content still to trust me.”

“I would not intrude upon your secrets, Mr. Haw,” said Robert, “but

of course I cannot deny that I should be very proud and pleased if you

cared to confide them to me.”

“And I will. Not all. I do not think that I shall ever, while I live,

tell all. But I shall leave directions behind me so that when I die you

may be able to carry on my unfinished work. I shall tell you where those

directions are to be found. In the meantime, you must be content to

learn the effects which I produce without knowing every detail as to the

means.”

Robert settled himself down in his chair and concentrated his attention

upon his companion's words, while Haw bent forward his eager, earnest

face, like a man who knows the value of the words which he is saying.

“You are already aware,” he remarked, “that I have devoted a great deal

of energy and of time to the study of chemistry.”

“So you told me.”

“I commenced my studies under a famous English chemist, I continued

them under the best man in France, and I completed them in the most

celebrated laboratory of Germany. I was not rich, but my father had left

me enough to keep me comfortably, and by living economically I had a

sum at my command which enabled me to carry out my studies in a very

complete way. When I returned to England I built myself a laboratory

in a quiet country place where I could work without distraction or

interruption. There I began a series of investigations which soon took

me into regions of science to which none of the three famous men who

taught me had ever penetrated.

“You say, Robert, that you have some slight knowledge of chemistry, and

you will find it easier to follow what I say. Chemistry is to a large

extent an empirical science, and the chance experiment may lead to

greater results than could, with our present data, be derived from the

closest study or the keenest reasoning. The most important chemical

discoveries from the first manufacture of glass to the whitening and

refining of sugar have all been due to some happy chance which might

have befallen a mere dabbler as easily as a deep student.

“Well, it was to such a chance that my own great discovery--perhaps the

greatest that the world has seen--was due, though I may claim the credit

of having originated the line of thought which led up to it. I had

frequently speculated as to the effect which powerful currents of

electricity exercise upon any substance through which they are poured

for a considerable time. I did not here mean such feeble currents as

are passed along a telegraph wire, but I mean the very highest possible

developments. Well, I tried a series of experiments upon this point. I

found that in liquids, and in compounds, the force had a disintegrating

effect. The well-known experiment of the electrolysis of water will, of

course, occur to you. But I found that in the case of elemental solids

the effect was a remarkable one. The element slowly decreased in weight,

without perceptibly altering in composition. I hope that I make myself

clear to you?”

“I follow you entirely,” said Robert, deeply interested in his

companion's narrative.

“I tried upon several elements, and always with the same result. In

every case an hour's current would produce a perceptible loss of weight.

My theory at that stage was that there was a loosening of the molecules

caused by the electric fluid, and that a certain number of these

molecules were shed off like an impalpable dust, all round the lump of

earth or of metal, which remained, of course, the lighter by their loss.

I had entirely accepted this theory, when a very remarkable chance led

me to completely alter my opinions.

“I had one Saturday night fastened a bar of bismuth in a clamp, and had

attached it on either side to an electric wire, in order to observe what

effect the current would have upon it. I had been testing each metal in

turn, exposing them to the influence for from one to two hours. I had

just got everything in position, and had completed my connection, when

I received a telegram to say that John Stillingfleet, an old chemist in

London with whom I had been on terms of intimacy, was dangerously ill,

and had expressed a wish to see me. The last train was due to leave in

twenty minutes, and I lived a good mile from the station, I thrust a few

things into a bag, locked my laboratory, and ran as hard as I could to

catch it.

“It was not until I was in London that it suddenly occurred to me that

I had neglected to shut off the current, and that it would continue to

pass through the bar of bismuth until the batteries were exhausted. The

fact, however, seemed to be of small importance, and I dismissed it from

my mind. I was detained in London until the Tuesday night, and it

was Wednesday morning before I got back to my work. As I unlocked the

laboratory door my mind reverted to the uncompleted experiment, and it

struck me that in all probability my piece of bismuth would have been

entirely disintegrated and reduced to its primitive molecules. I was

utterly unprepared for the truth.

“When I approached the table I found, sure enough, that the bar of metal

had vanished, and that the clamp was empty. Having noted the fact, I was

about to turn away to something else, when my attention was attracted to

the fact that the table upon which the clamp stood was starred over with

little patches of some liquid silvery matter, which lay in single drops

or coalesced into little pools. I had a very distinct recollection of

having thoroughly cleared the table before beginning my experiment,

so that this substance had been deposited there since I had left for

London. Much interested, I very carefully collected it all into one

vessel, and examined it minutely. There could be no question as to what

it was. It was the purest mercury, and gave no response to any test for

bismuth.

“I at once grasped the fact that chance had placed in my hands a

chemical discovery of the very first importance. If bismuth were, under

certain conditions, to be subjected to the action of electricity, it

would begin by losing weight, and would finally be transformed into

mercury. I had broken down the partition which separated two elements.

“But the process would be a constant one. It would presumably prove

to be a general law, and not an isolated fact. If bismuth turned into

mercury, what would mercury turn into? There would be no rest for me

until I had solved the question. I renewed the exhausted batteries and

passed the current through the bowl of quicksilver. For sixteen hours I

sat watching the metal, marking how it slowly seemed to curdle, to grow

firmer, to lose its silvery glitter and to take a dull yellow hue. When

I at last picked it up in a forceps, and threw it upon the table, it had

lost every characteristic of mercury, and had obviously become another

metal. A few simple tests were enough to show me that this other metal

was platinum.

“Now, to a chemist, there was something very suggestive in the order in

which these changes had been effected. Perhaps you can see the relation,

Robert, which they bear to each other?”

“No, I cannot say that I do.”

Robert had sat listening to this strange statement with parted lips and

staring eyes.

“I will show you. Speaking atomically, bismuth is the heaviest of the

metals. Its atomic weight is 210. The next in weight is lead, 207, and

then comes mercury at 200. Possibly the long period during which the

current had acted in my absence had reduced the bismuth to lead and

the lead in turn to mercury. Now platinum stands at 197.5, and it was

accordingly the next metal to be produced by the continued current. Do

you see now?”

“It is quite clear.”

“And then there came the inference, which sent my heart into my mouth

and caused my head to swim round. Gold is the next in the series.

Its atomic weight is 197. I remembered now, and for the first time

understood why it was always lead and mercury winch were mentioned by

the old alchemists as being the two metals which might be used in their

calling. With fingers which trembled with excitement I adjusted the

wires again, and in little more than an hour--for the length of the

process was always in proportion to the difference in the metals--I

had before me a knob of ruddy crinkled metal, which answered to every

reaction for gold.

“Well, Robert, this is a long story, but I think that you will agree

with me that its importance justifies me in going into detail. When

I had satisfied myself that I had really manufactured gold I cut the

nugget in two. One half I sent to a jeweller and worker in precious

metals, with whom I had some slight acquaintance, asking him to report

upon the quality of the metal. With the other half I continued my series

of experiments, and reduced it in successive stages through all the long

series of metals, through silver and zinc and manganese, until I brought

it to lithium, which is the lightest of all.”

“And what did it turn to then?” asked Robert.

“Then came what to chemists is likely to be the most interesting portion

of my discovery. It turned to a greyish fine powder, which powder gave

no further results, however much I might treat it with electricity.

And that powder is the base of all things; it is the mother of all

the elements; it is, in short, the substance whose existence has been

recently surmised by a leading chemist, and which has been christened

protyle by him. I am the discoverer of the great law of the electrical

transposition of the metals, and I am the first to demonstrate protyle,

so that, I think, Robert, if all my schemes in other directions come to

nothing, my name is at least likely to live in the chemical world.

“There is not very much more for me to tell you. I had my nugget back

from my friend the jeweller, confirming my opinion as to its nature and

its quality. I soon found several methods by which the process might

be simplified, and especially a modification of the ordinary electric

current, which was very much more effective. Having made a certain

amount of gold, I disposed of it for a sum which enabled me to buy

improved materials and stronger batteries. In this way I enlarged my

operations until at last I was in a position to build this house and

to have a laboratory where I could carry out my work on a much larger

scale. As I said before, I can now state with all truth that the amount

of my income is only limited by my desires.”

“It is wonderful!” gasped Robert. “It is like a fairy tale. But with

this great discovery in your mind you must have been sorely tempted to

confide it to others.”

“I thought well over it. I gave it every consideration. It was obvious

to me that if my invention were made public, its immediate result would

be to deprive the present precious metals of all their special value.

Some other substance--amber, we will say, or ivory--would be chosen as a

medium for barter, and gold would be inferior to brass, as being heavier

and yet not so hard. 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.”
