No More Learning

Holmes, that you have already made up your mind,"
said Miss Stoner, laying her hand upon my companion's sleeve.

"Perhaps I have. "

"Then, for pity's sake, tell me what was the cause of my sister's
death. "

"I should prefer to have clearer proofs before I speak. "

"You can at least tell me whether my own thought is correct, and
if she died from some sudden fright. "

"No, I do not think so. I think that there was probably some more
tangible cause. And now, Miss Stoner, we must leave you for if
Dr. Roylott returned and saw us our journey would be in vain.
Good-bye, and be brave, for if you will do what I have told you,
you may rest assured that we shall soon drive away the dangers
that threaten you. "

Sherlock Holmes and I had no difficulty in engaging a bedroom and
sitting-room at the Crown Inn. They were on the upper floor, and
from our window we could command a view of the avenue gate, and
of the inhabited wing of Stoke Moran Manor House. At dusk we saw
Dr. Grimesby Roylott drive past, his huge form looming up beside
the little figure of the lad who drove him. The boy had some
slight difficulty in undoing the heavy iron gates, and we heard
the hoarse roar of the doctor's voice and saw the fury with which
he shook his clinched fists at him. The trap drove on, and a few
minutes later we saw a sudden light spring up among the trees as
the lamp was lit in one of the sitting-rooms.

"Do you know, Watson," said Holmes as we sat together in the
gathering darkness, "I have really some scruples as to taking you
to-night. There is a distinct element of danger. "

"Can I be of assistance? "

"Your presence might be invaluable. "

"Then I shall certainly come. "

"It is very kind of you. "

"You speak of danger. You have evidently seen more in these rooms
than was visible to me. "

"No, but I fancy that I may have deduced a little more. I imagine
that you saw all that I did. "

"I saw nothing remarkable save the bell-rope, and what purpose
that could answer I confess is more than I can imagine. "

"You saw the ventilator, too? "

"Yes, but I do not think that it is such a very unusual thing to
have a small opening between two rooms. It was so small that a
rat could hardly pass through. "

"I knew that we should find a ventilator before ever we came to
Stoke Moran. "

"My dear Holmes! "

"Oh, yes, I did. You remember in her statement she said that her
sister could smell Dr. Roylott's cigar. Now, of course that
suggested at once that there must be a communication between the
two rooms. It could only be a small one, or it would have been
remarked upon at the coroner's inquiry. I deduced a ventilator. "

"But what harm can there be in that? "

"Well, there is at least a curious coincidence of dates. A
ventilator is made, a cord is hung, and a lady who sleeps in the
bed dies. Does not that strike you? "

"I cannot as yet see any connection. "

"Did you observe anything very peculiar about that bed? "

"No. "

"It was clamped to the floor. Did you ever see a bed fastened
like that before? "

"I cannot say that I have. "

"The lady could not move her bed. It must always be in the same
relative position to the ventilator and to the rope--or so we may
call it, since it was clearly never meant for a bell-pull. "

"Holmes," I cried, "I seem to see dimly what you are hinting at.
We are only just in time to prevent some subtle and horrible
crime. "

"Subtle enough and horrible enough. When a doctor does go wrong
he is the first of criminals. He has nerve and he has knowledge.
Palmer and Pritchard were among the heads of their profession.
This man strikes even deeper, but I think, Watson, that we shall
be able to strike deeper still. But we shall have horrors enough
before the night is over; for goodness' sake let us have a quiet
pipe and turn our minds for a few hours to something more
cheerful. "


About nine o'clock the light among the trees was extinguished,
and all was dark in the direction of the Manor House. Two hours
passed slowly away, and then, suddenly, just at the stroke of
eleven, a single bright light shone out right in front of us.

"That is our signal," said Holmes, springing to his feet; "it
comes from the middle window. "

As we passed out he exchanged a few words with the landlord,
explaining that we were going on a late visit to an acquaintance,
and that it was possible that we might spend the night there. A
moment later we were out on the dark road, a chill wind blowing
in our faces, and one yellow light twinkling in front of us
through the gloom to guide us on our sombre errand.

There was little difficulty in entering the grounds, for
unrepaired breaches gaped in the old park wall. Making our way
among the trees, we reached the lawn, crossed it, and were about
to enter through the window when out from a clump of laurel
bushes there darted what seemed to be a hideous and distorted
child, who threw itself upon the grass with writhing limbs and
then ran swiftly across the lawn into the darkness.

"My God! " I whispered; "did you see it? "

Holmes was for the moment as startled as I. His hand closed like
a vice upon my wrist in his agitation. Then he broke into a low
laugh and put his lips to my ear.

"It is a nice household," he murmured. "That is the baboon. "

I had forgotten the strange pets which the doctor affected. There
was a cheetah, too; perhaps we might find it upon our shoulders
at any moment. I confess that I felt easier in my mind when,
after following Holmes' example and slipping off my shoes, I
found myself inside the bedroom. My companion noiselessly closed
the shutters, moved the lamp onto the table, and cast his eyes
round the room. All was as we had seen it in the daytime. Then
creeping up to me and making a trumpet of his hand, he whispered
into my ear again so gently that it was all that I could do to
distinguish the words:

"The least sound would be fatal to our plans. "

I nodded to show that I had heard.

"We must sit without light. He would see it through the
ventilator. "

I nodded again.

"Do not go asleep; your very life may depend upon it. Have your
pistol ready in case we should need it. I will sit on the side of
the bed, and you in that chair. "

I took out my revolver and laid it on the corner of the table.

Holmes had brought up a long thin cane, and this he placed upon
the bed beside him. By it he laid the box of matches and the
stump of a candle. Then he turned down the lamp, and we were left
in darkness.

How shall I ever forget that dreadful vigil? I could not hear a
sound, not even the drawing of a breath, and yet I knew that my
companion sat open-eyed, within a few feet of me, in the same
state of nervous tension in which I was myself. The shutters cut
off the least ray of light, and we waited in absolute darkness.

From outside came the occasional cry of a night-bird, and once at
our very window a long drawn catlike whine, which told us that
the cheetah was indeed at liberty. Far away we could hear the
deep tones of the parish clock, which boomed out every quarter of
an hour. How long they seemed, those quarters! Twelve struck, and
one and two and three, and still we sat waiting silently for
whatever might befall.

Suddenly there was the momentary gleam of a light up in the
direction of the ventilator, which vanished immediately, but was
succeeded by a strong smell of burning oil and heated metal.
Someone in the next room had lit a dark-lantern. I heard a gentle
sound of movement, and then all was silent once more, though the
smell grew stronger. For half an hour I sat with straining ears.
Then suddenly another sound became audible--a very gentle,
soothing sound, like that of a small jet of steam escaping
continually from a kettle. The instant that we heard it, Holmes
sprang from the bed, struck a match, and lashed furiously with
his cane at the bell-pull.

"You see it, Watson? " he yelled. "You see it? "

But I saw nothing. At the moment when Holmes struck the light I
heard a low, clear whistle, but the sudden glare flashing into my
weary eyes made it impossible for me to tell what it was at which
my friend lashed so savagely. I could, however, see that his face
was deadly pale and filled with horror and loathing. He had
ceased to strike and was gazing up at the ventilator when
suddenly there broke from the silence of the night the most
horrible cry to which I have ever listened. It swelled up louder
and louder, a hoarse yell of pain and fear and anger all mingled
in the one dreadful shriek. They say that away down in the
village, and even in the distant parsonage, that cry raised the
sleepers from their beds. It struck cold to our hearts, and I
stood gazing at Holmes, and he at me, until the last echoes of it
had died away into the silence from which it rose.

"What can it mean? " I gasped.

"It means that it is all over," Holmes answered. "And perhaps,
after all, it is for the best. Take your pistol, and we will
enter Dr. Roylott's room. "

With a grave face he lit the lamp and led the way down the
corridor. Twice he struck at the chamber door without any reply
from within. Then he turned the handle and entered, I at his
heels, with the cocked pistol in my hand.

It was a singular sight which met our eyes. On the table stood a
dark-lantern with the shutter half open, throwing a brilliant
beam of light upon the iron safe, the door of which was ajar.
Beside this table, on the wooden chair, sat Dr. Grimesby Roylott
clad in a long grey dressing-gown, his bare ankles protruding
beneath, and his feet thrust into red heelless Turkish slippers.
Across his lap lay the short stock with the long lash which we
had noticed during the day. His chin was cocked upward and his
eyes were fixed in a dreadful, rigid stare at the corner of the
ceiling. Round his brow he had a peculiar yellow band, with
brownish speckles, which seemed to be bound tightly round his
head. As we entered he made neither sound nor motion.

"The band! the speckled band! " whispered Holmes.

I took a step forward. In an instant his strange headgear began
to move, and there reared itself from among his hair the squat
diamond-shaped head and puffed neck of a loathsome serpent.

"It is a swamp adder! " cried Holmes; "the deadliest snake in
India. He has died within ten seconds of being bitten. Violence
does, in truth, recoil upon the violent, and the schemer falls
into the pit which he digs for another. Let us thrust this
creature back into its den, and we can then remove Miss Stoner to
some place of shelter and let the county police know what has
happened. "

As he spoke he drew the dog-whip swiftly from the dead man's lap,
and throwing the noose round the reptile's neck he drew it from
its horrid perch and, carrying it at arm's length, threw it into
the iron safe, which he closed upon it.

Such are the true facts of the death of Dr. Grimesby Roylott, of
Stoke Moran. It is not necessary that I should prolong a
narrative which has already run to too great a length by telling
how we broke the sad news to the terrified girl, how we conveyed
her by the morning train to the care of her good aunt at Harrow,
of how the slow process of official inquiry came to the
conclusion that the doctor met his fate while indiscreetly
playing with a dangerous pet. The little which I had yet to learn
of the case was told me by Sherlock Holmes as we travelled back
next day.

"I had," said he, "come to an entirely erroneous conclusion which
shows, my dear Watson, how dangerous it always is to reason from
insufficient data. The presence of the gipsies, and the use of
the word 'band,' which was used by the poor girl, no doubt, to
explain the appearance which she had caught a hurried glimpse of
by the light of her match, were sufficient to put me upon an
entirely wrong scent. I can only claim the merit that I instantly
reconsidered my position when, however, it became clear to me
that whatever danger threatened an occupant of the room could not
come either from the window or the door. My attention was
speedily drawn, as I have already remarked to you, to this
ventilator, and to the bell-rope which hung down to the bed. The
discovery that this was a dummy, and that the bed was clamped to
the floor, instantly gave rise to the suspicion that the rope was
there as a bridge for something passing through the hole and
coming to the bed. The idea of a snake instantly occurred to me,
and when I coupled it with my knowledge that the doctor was
furnished with a supply of creatures from India, I felt that I
was probably on the right track. The idea of using a form of
poison which could not possibly be discovered by any chemical
test was just such a one as would occur to a clever and ruthless
man who had had an Eastern training. The rapidity with which such
a poison would take effect would also, from his point of view, be
an advantage. It would be a sharp-eyed coroner, indeed, who could
distinguish the two little dark punctures which would show where
the poison fangs had done their work. Then I thought of the
whistle. Of course he must recall the snake before the morning
light revealed it to the victim. He had trained it, probably by
the use of the milk which we saw, to return to him when summoned.
He would put it through this ventilator at the hour that he
thought best, with the certainty that it would crawl down the
rope and land on the bed. It might or might not bite the
occupant, perhaps she might escape every night for a week, but
sooner or later she must fall a victim.

"I had come to these conclusions before ever I had entered his
room. An inspection of his chair showed me that he had been in
the habit of standing on it, which of course would be necessary
in order that he should reach the ventilator. The sight of the
safe, the saucer of milk, and the loop of whipcord were enough to
finally dispel any doubts which may have remained. The metallic
clang heard by Miss Stoner was obviously caused by her stepfather
hastily closing the door of his safe upon its terrible occupant.
Having once made up my mind, you know the steps which I took in
order to put the matter to the proof. I heard the creature hiss
as I have no doubt that you did also, and I instantly lit the
light and attacked it. "

"With the result of driving it through the ventilator. "

"And also with the result of causing it to turn upon its master
at the other side. Some of the blows of my cane came home and
roused its snakish temper, so that it flew upon the first person
it saw. In this way I am no doubt indirectly responsible for Dr.
Grimesby Roylott's death, and I cannot say that it is likely to
weigh very heavily upon my conscience. "



IX. THE ADVENTURE OF THE ENGINEER'S THUMB

Of all the problems which have been submitted to my friend, Mr.
Sherlock Holmes, for solution during the years of our intimacy,
there were only two which I was the means of introducing to his
notice--that of Mr. Hatherley's thumb, and that of Colonel
Warburton's madness. Of these the latter may have afforded a
finer field for an acute and original observer, but the other was
so strange in its inception and so dramatic in its details that
it may be the more worthy of being placed upon record, even if it
gave my friend fewer openings for those deductive methods of
reasoning by which he achieved such remarkable results. The story
has, I believe, been told more than once in the newspapers, but,
like all such narratives, its effect is much less striking when
set forth en bloc in a single half-column of print than when the
facts slowly evolve before your own eyes, and the mystery clears
gradually away as each new discovery furnishes a step which leads
on to the complete truth. At the time the circumstances made a
deep impression upon me, and the lapse of two years has hardly
served to weaken the effect.

It was in the summer of '89, not long after my marriage, that the
events occurred which I am now about to summarise. I had returned
to civil practice and had finally abandoned Holmes in his Baker
Street rooms, although I continually visited him and occasionally
even persuaded him to forgo his Bohemian habits so far as to come
and visit us. My practice had steadily increased, and as I
happened to live at no very great distance from Paddington
Station, I got a few patients from among the officials. One of
these, whom I had cured of a painful and lingering disease, was
never weary of advertising my virtues and of endeavouring to send
me on every sufferer over whom he might have any influence.

One morning, at a little before seven o'clock, I was awakened by
the maid tapping at the door to announce that two men had come
from Paddington and were waiting in the consulting-room. I
dressed hurriedly, for I knew by experience that railway cases
were seldom trivial, and hastened downstairs. As I descended, my
old ally, the guard, came out of the room and closed the door
tightly behind him.

"I've got him here," he whispered, jerking his thumb over his
shoulder; "he's all right. "

"What is it, then? " I asked, for his manner suggested that it was
some strange creature which he had caged up in my room.

"It's a new patient," he whispered. "I thought I'd bring him
round myself; then he couldn't slip away. There he is, all safe
and sound. I must go now, Doctor; I have my dooties, just the
same as you. " And off he went, this trusty tout, without even
giving me time to thank him.

I entered my consulting-room and found a gentleman seated by the
table. He was quietly dressed in a suit of heather tweed with a
soft cloth cap which he had laid down upon my books. Round one of
his hands he had a handkerchief wrapped, which was mottled all
over with bloodstains. He was young, not more than
five-and-twenty, I should say, with a strong, masculine face; but
he was exceedingly pale and gave me the impression of a man who
was suffering from some strong agitation, which it took all his
strength of mind to control.

"I am sorry to knock you up so early, Doctor," said he, "but I
have had a very serious accident during the night. I came in by
train this morning, and on inquiring at Paddington as to where I
might find a doctor, a worthy fellow very kindly escorted me
here. I gave the maid a card, but I see that she has left it upon
the side-table. "

I took it up and glanced at it. "Mr.
Victor Hatherley, hydraulic
engineer, 16A, Victoria Street (3rd floor). " That was the name,
style, and abode of my morning visitor. "I regret that I have
kept you waiting," said I, sitting down in my library-chair. "You
are fresh from a night journey, I understand, which is in itself
a monotonous occupation. "

"Oh, my night could not be called monotonous," said he, and
laughed. He laughed very heartily, with a high, ringing note,
leaning back in his chair and shaking his sides. All my medical
instincts rose up against that laugh.

"Stop it! " I cried; "pull yourself together! " and I poured out
some water from a caraffe.

It was useless, however. He was off in one of those hysterical
outbursts which come upon a strong nature when some great crisis
is over and gone. Presently he came to himself once more, very
weary and pale-looking.

"I have been making a fool of myself," he gasped.

"Not at all. Drink this. " I dashed some brandy into the water,
and the colour began to come back to his bloodless cheeks.

"That's better! " said he. "And now, Doctor, perhaps you would
kindly attend to my thumb, or rather to the place where my thumb
used to be. "

He unwound the handkerchief and held out his hand. It gave even
my hardened nerves a shudder to look at it. There were four
protruding fingers and a horrid red, spongy surface where the
thumb should have been. It had been hacked or torn right out from
the roots.

"Good heavens! " I cried, "this is a terrible injury. It must have
bled considerably. "

"Yes, it did. I fainted when it was done, and I think that I must
have been senseless for a long time. When I came to I found that
it was still bleeding, so I tied one end of my handkerchief very
tightly round the wrist and braced it up with a twig. "

"Excellent! You should have been a surgeon. "

"It is a question of hydraulics, you see, and came within my own
province. "

"This has been done," said I, examining the wound, "by a very
heavy and sharp instrument. "

"A thing like a cleaver," said he.

"An accident, I presume? "

"By no means. "

"What! a murderous attack? "

"Very murderous indeed. "

"You horrify me. "

I sponged the wound, cleaned it, dressed it, and finally covered
it over with cotton wadding and carbolised bandages. He lay back
without wincing, though he bit his lip from time to time.

"How is that? " I asked when I had finished.

"Capital! Between your brandy and your bandage, I feel a new man.
I was very weak, but I have had a good deal to go through. "

"Perhaps you had better not speak of the matter. It is evidently
trying to your nerves. "

"Oh, no, not now. I shall have to tell my tale to the police;
but, between ourselves, if it were not for the convincing
evidence of this wound of mine, I should be surprised if they
believed my statement, for it is a very extraordinary one, and I
have not much in the way of proof with which to back it up; and,
even if they believe me, the clues which I can give them are so
vague that it is a question whether justice will be done. "

"Ha! " cried I, "if it is anything in the nature of a problem
which you desire to see solved, I should strongly recommend you
to come to my friend, Mr. Sherlock Holmes, before you go to the
official police. "

"Oh, I have heard of that fellow," answered my visitor, "and I
should be very glad if he would take the matter up, though of
course I must use the official police as well. Would you give me
an introduction to him? "

"I'll do better. I'll take you round to him myself. "

"I should be immensely obliged to you. "

"We'll call a cab and go together. We shall just be in time to
have a little breakfast with him. Do you feel equal to it? "

"Yes; I shall not feel easy until I have told my story. "

"Then my servant will call a cab, and I shall be with you in an
instant. " I rushed upstairs, explained the matter shortly to my
wife, and in five minutes was inside a hansom, driving with my
new acquaintance to Baker Street.

Sherlock Holmes was, as I expected, lounging about his
sitting-room in his dressing-gown, reading the agony column of The
Times and smoking his before-breakfast pipe, which was composed
of all the plugs and dottles left from his smokes of the day
before, all carefully dried and collected on the corner of the
mantelpiece. He received us in his quietly genial fashion,
ordered fresh rashers and eggs, and joined us in a hearty meal.
When it was concluded he settled our new acquaintance upon the
sofa, placed a pillow beneath his head, and laid a glass of
brandy and water within his reach.

"It is easy to see that your experience has been no common one,
Mr. Hatherley," said he. "Pray, lie down there and make yourself
absolutely at home. Tell us what you can, but stop when you are
tired and keep up your strength with a little stimulant. "

"Thank you," said my patient, "but I have felt another man since
the doctor bandaged me, and I think that your breakfast has
completed the cure. I shall take up as little of your valuable
time as possible, so I shall start at once upon my peculiar
experiences. "

Holmes sat in his big armchair with the weary, heavy-lidded
expression which veiled his keen and eager nature, while I sat
opposite to him, and we listened in silence to the strange story
which our visitor detailed to us.

"You must know," said he, "that I am an orphan and a bachelor,
residing alone in lodgings in London. By profession I am a
hydraulic engineer, and I have had considerable experience of my
work during the seven years that I was apprenticed to Venner &
Matheson, the well-known firm, of Greenwich. Two years ago,
having served my time, and having also come into a fair sum of
money through my poor father's death, I determined to start in
business for myself and took professional chambers in Victoria
Street.

"I suppose that everyone finds his first independent start in
business a dreary experience. To me it has been exceptionally so.
During two years I have had three consultations and one small
job, and that is absolutely all that my profession has brought
me. My gross takings amount to 27 pounds 10s. Every day, from
nine in the morning until four in the afternoon, I waited in my
little den, until at last my heart began to sink, and I came to
believe that I should never have any practice at all.

"Yesterday, however, just as I was thinking of leaving the
office, my clerk entered to say there was a gentleman waiting who
wished to see me upon business. He brought up a card, too, with
the name of 'Colonel Lysander Stark' engraved upon it. Close at
his heels came the colonel himself, a man rather over the middle
size, but of an exceeding thinness. I do not think that I have
ever seen so thin a man. His whole face sharpened away into nose
and chin, and the skin of his cheeks was drawn quite tense over
his outstanding bones. Yet this emaciation seemed to be his
natural habit, and due to no disease, for his eye was bright, his
step brisk, and his bearing assured. He was plainly but neatly
dressed, and his age, I should judge, would be nearer forty than
thirty.

"'Mr. Hatherley? ' said he, with something of a German accent.
'You have been recommended to me, Mr. Hatherley, as being a man
who is not only proficient in his profession but is also discreet
and capable of preserving a secret. '

"I bowed, feeling as flattered as any young man would at such an
address. 'May I ask who it was who gave me so good a character? '

"'Well, perhaps it is better that I should not tell you that just
at this moment. I have it from the same source that you are both
an orphan and a bachelor and are residing alone in London. '

"'That is quite correct,' I answered; 'but you will excuse me if
I say that I cannot see how all this bears upon my professional
qualifications. I understand that it was on a professional matter
that you wished to speak to me? '

"'Undoubtedly so. But you will find that all I say is really to
the point. I have a professional commission for you, but absolute
secrecy is quite essential--absolute secrecy, you understand, and
of course we may expect that more from a man who is alone than
from one who lives in the bosom of his family. '

"'If I promise to keep a secret,' said I, 'you may absolutely
depend upon my doing so. '

"He looked very hard at me as I spoke, and it seemed to me that I
had never seen so suspicious and questioning an eye.

"'Do you promise, then? ' said he at last.

"'Yes, I promise. '

"'Absolute and complete silence before, during, and after? No
reference to the matter at all, either in word or writing? '

"'I have already given you my word. '

"'Very good. ' He suddenly sprang up, and darting like lightning
across the room he flung open the door. The passage outside was
empty.

"'That's all right,' said he, coming back. 'I know that clerks are
sometimes curious as to their master's affairs. Now we can talk
in safety. ' He drew up his chair very close to mine and began to
stare at me again with the same questioning and thoughtful look.

"A feeling of repulsion, and of something akin to fear had begun
to rise within me at the strange antics of this fleshless man.
Even my dread of losing a client could not restrain me from
showing my impatience.

"'I beg that you will state your business, sir,' said I; 'my time
is of value. ' Heaven forgive me for that last sentence, but the
words came to my lips.

"'How would fifty guineas for a night's work suit you? ' he asked.

"'Most admirably. '

"'I say a night's work, but an hour's would be nearer the mark. I
simply want your opinion about a hydraulic stamping machine which
has got out of gear. If you show us what is wrong we shall soon
set it right ourselves. What do you think of such a commission as
that? '

"'The work appears to be light and the pay munificent. '

"'Precisely so. We shall want you to come to-night by the last
train. '

"'Where to? '

"'To Eyford, in Berkshire. It is a little place near the borders
of Oxfordshire, and within seven miles of Reading. There is a
train from Paddington which would bring you there at about
11:15. '

"'Very good. '

"'I shall come down in a carriage to meet you. '

"'There is a drive, then? '

"'Yes, our little place is quite out in the country. It is a good
seven miles from Eyford Station. '

"'Then we can hardly get there before midnight. I suppose there
would be no chance of a train back. I should be compelled to stop
the night. '

"'Yes, we could easily give you a shake-down. '

"'That is very awkward. Could I not come at some more convenient
hour? '

"'We have judged it best that you should come late. It is to
recompense you for any inconvenience that we are paying to you, a
young and unknown man, a fee which would buy an opinion from the
very heads of your profession. Still, of course, if you would
like to draw out of the business, there is plenty of time to do
so. '

"I thought of the fifty guineas, and of how very useful they
would be to me. 'Not at all,' said I, 'I shall be very happy to
accommodate myself to your wishes. I should like, however, to
understand a little more clearly what it is that you wish me to
do. '

"'Quite so. It is very natural that the pledge of secrecy which
we have exacted from you should have aroused your curiosity. I
have no wish to commit you to anything without your having it all
laid before you. I suppose that we are absolutely safe from
eavesdroppers? '

"'Entirely. '

"'Then the matter stands thus. You are probably aware that
fuller's-earth is a valuable product, and that it is only found
in one or two places in England? '

"'I have heard so. '

"'Some little time ago I bought a small place--a very small
place--within ten miles of Reading. I was fortunate enough to
discover that there was a deposit of fuller's-earth in one of my
fields. On examining it, however, I found that this deposit was a
comparatively small one, and that it formed a link between two
very much larger ones upon the right and left--both of them,
however, in the grounds of my neighbours. These good people were
absolutely ignorant that their land contained that which was
quite as valuable as a gold-mine. Naturally, it was to my
interest to buy their land before they discovered its true value,
but unfortunately I had no capital by which I could do this. I
took a few of my friends into the secret, however, and they
suggested that we should quietly and secretly work our own little
deposit and that in this way we should earn the money which would
enable us to buy the neighbouring fields. This we have now been
doing for some time, and in order to help us in our operations we
erected a hydraulic press. This press, as I have already
explained, has got out of order, and we wish your advice upon the
subject. We guard our secret very jealously, however, and if it
once became known that we had hydraulic engineers coming to our
little house, it would soon rouse inquiry, and then, if the facts
came out, it would be good-bye to any chance of getting these
fields and carrying out our plans. That is why I have made you
promise me that you will not tell a human being that you are
going to Eyford to-night. I hope that I make it all plain? '

"'I quite follow you,' said I. 'The only point which I could not
quite understand was what use you could make of a hydraulic press
in excavating fuller's-earth, which, as I understand, is dug out
like gravel from a pit. '

"'Ah! ' said he carelessly, 'we have our own process. We compress
the earth into bricks, so as to remove them without revealing
what they are. But that is a mere detail. I have taken you fully
into my confidence now, Mr. Hatherley, and I have shown you how I
trust you. ' He rose as he spoke. 'I shall expect you, then, at
Eyford at 11:15. '

"'I shall certainly be there. '

"'And not a word to a soul. ' He looked at me with a last long,

which had been intrusted to me. On the one hand, of course, I was
glad, for the fee was at least tenfold what I should have asked

this order might lead to other ones. On the other hand, the face
and manner of my patron had made an unpleasant impression upon
me, and I could not think that his explanation of the
fuller's-earth was sufficient to explain the necessity for my
coming at midnight, and his extreme anxiety lest I should tell
anyone of my errand. However, I threw all fears to the winds, ate
a hearty supper, drove to Paddington, and started off, having
obeyed to the letter the injunction as to holding my tongue.

"At Reading I had to change not only my carriage but my station.
However, I was in time for the last train to Eyford, and I
reached the little dim-lit station after eleven o'clock. I was the
only passenger who got out there, and there was no one upon the
platform save a single sleepy porter with a lantern. As I passed
out through the wicket gate, however, I found my acquaintance of
the morning waiting in the shadow upon the other side. Without a
word he grasped my arm and hurried me into a carriage, the door
of which was standing open. He drew up the windows on either
side, tapped on the wood-work, and away we went as fast as the
horse could go. "

"One horse? " interjected Holmes.

"Yes, only one. "

"Did you observe the colour?
