<h2> CHAPTER X. THE GREAT SECRET. </h2>
<p>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.</p>
<p>“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.”</p>
<p>“Laura is greatly changed,” Robert answered; “she has grown much more
serious in her ideas.”</p>
<p>“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.”</p>
<p>“You have only to ask for what you want.”</p>
<p>“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.</p>
<p>“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.”</p>
<p>“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.</p>
<p>“At least you shall not go without Laura knowing. I will call her down,
and we shall have her opinion.”</p>
<p>“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.</p>
<p>“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.”</p>
<p>He had hardly spoken when there was a tap at the door, and the man of whom
they were speaking walked in.</p>
<p>“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.</p>
<p>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.</p>
<p>“By the way, Robert,” said Raffles Haw suddenly, as they walked up the
Avenue. “Has your great Roman picture gone to London?”</p>
<p>“I have not finished it yet.”</p>
<p>“But I know that you are a quick worker. You must be nearly at the end of
it.”</p>
<p>“No, I am afraid that it has not advanced much since you saw it. For one
thing, the light has not been very good.”</p>
<p>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.</p>
<p>“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.”</p>
<p>He threw himself down into a settee, and motioned Robert into the armchair
in front of him.</p>
<p>“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.”</p>
<p>The charge was so direct and so true that the young artist hesitated,
hardly knowing how to answer.</p>
<p>“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.”</p>
<p>“I have had ample proof of your immense wealth,” said Robert.</p>
<p>“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.”</p>
<p>“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.”</p>
<p>“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.”</p>
<p>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.</p>
<p>“You are already aware,” he remarked, “that I have devoted a great deal of
energy and of time to the study of chemistry.”</p>
<p>“So you told me.”</p>
<p>“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.</p>
<p>“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.</p>
<p>“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?”</p>
<p>“I follow you entirely,” said Robert, deeply interested in his companion's
narrative.</p>
<p>“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.</p>
<p>“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.</p>
<p>“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.</p>
<p>“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.</p>
<p>“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.</p>
<p>“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.</p>
<p>“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?”</p>
<p>“No, I cannot say that I do.”</p>
<p>Robert had sat listening to this strange statement with parted lips and
staring eyes.</p>
<p>“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?”</p>
<p>“It is quite clear.”</p>
<p>“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.</p>
<p>“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.”</p>
<p>“And what did it turn to then?” asked Robert.</p>
<p>“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.</p>
<p>“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.”</p>
<p>“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.”</p>
<p>“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.”</p>
<p>“But your secret is safe with me,” cried Robert. “My lips shall be sealed
until I have your permission to speak.”</p>
<p>“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.”</p>
