1.--THE DIVINING ROD.

_February_, 1847.

DEAR ARCHY,--As a resource against the long ennui of the solitary

evenings of commencing winter, I determined to betake me to the

neglected lore of the marvellous, the mystical, the supernatural. I

remembered the deep awe with which I had listened many a year ago to

tales of seers, and ghosts, and vampires, and all the dark brood of

night; and I thought it would be infinitely agreeable to thrill again

with mysterious terrors, to start in my chair at the closing of a

distant door, to raise my eyes with uneasy apprehension towards the

mirror opposite, and to feel my skin creep with the sensible "afflatus"

of an invisible presence. I entered, accordingly, upon what I thought a

very promising course of appalling reading; but, alack and well-a-day! a

change has come over me since the good old times, when Fancy, with Fear

and Superstition behind her, would creep on tiptoe to catch a shuddering

glimpse of Cobbold Fay, or Incubus. Vain were all my efforts to revive

the pleasant horrors of earlier years. It was as if I had planned going

to the play to enjoy again the full gusto of scenic illusion, and

through some unaccountable absence of mind, was attending a morning

rehearsal only; when, instead of what I had expected, great coats, hats,

umbrellas, and ordinary men and women, masks, tinsel, trap-doors,

pulleys, and a world of intricate machinery, lit by a partial gleam of

sunshine, had met my view. The spell I had anticipated was not there.

But yet the daylight scene was worth a few minutes' study. My

imagination was not to be gratified; but still it might be entertaining

to see how the tricks are done, the effects produced, the illusion

realised. I found myself insensibly growing philosophical; what amused

me became matter of speculation--speculation turned into serious

inquiry--the object of which shaped itself into "the amount of truth

contained in popular superstitions." For what has been believed for ages

must have something real at bottom. There can be no prevalent delusion

without a corresponding truth. If the dragons, that flew on scaly wings

and expectorated flames, were fabulous, there existed nevertheless very

respectable reptiles, which it was a credit to a hero or even a saint to

destroy. If the Egyptian worship of cats and onions was a mistake, there

existed nevertheless an object of worship.

Among the immortal productions of the Scottish Shakspeare,--you smile,

but _that_ phrase contains the true belief, not a popular delusion; for

the spirit of the poet lived not in the form of his productions, but in

his creative power and vivid intuition of nature; and the form even is

often nearer you than you think: See the works of imaginative prose

writers, _passim_.

Well, among the novels of Scott, I was going to say, none perhaps more

grows upon our preference than the Antiquary. In no one has the great

Author more gently and more indulgently, never with happier humour,

displayed the mixed web of strength and infirmity of human character,

(never, besides, with more facile power evoked pathos and terror, or

disported himself in the sublimity and beauty of nature.) Yet gentle as

is his mood, he misses not the opportunity, albeit in general he betrays

an honest leaning towards old superstitions, mercilessly to crush one of

the humblest. Do you remember the Priory of St. Ruth, and the pleasant

summer party made to visit it, and the preparation for the subsequent

rogueries of Dousterswivel, in the tale of Martin Waldeck, and the

discovery of a spring of water by means of the divining rod?

I am disposed, do you know, to rebel against the judgment of the

novelist on this occasion,--to take the part of the charlatan against

the author of his being, and to question, whether his performance last

alluded to might not have been something more and better than a trick.

Yet I know not if it is prudent to brave public opinion, which has

stamped this pretension as imposture. But, courage! I will not flinch. I

will be desperate, with Sir Arthur, defy the sneeze of the great

Pheulphan, and trust to unearth a real treasure in this discredited

ground.

Therefore leave off appealing to the shade of Oldbuck, and listen to a

plain narrative, and you shall hear how much truth there is in the

reputed popular delusion of the divining rod.

I see my tone of confidence has already half-staggered your disbelief;

but pray do not, like many other incredulous gentry, run off at once

into the opposite extreme. Don't let your imagination suddenly instal

you perpetual chairman of the universal fresh-water company, or of the

general gold-mine-discovery-proprietary-association. What I have to fell

you falls very far short of so splendid a mark.

But perhaps you know nothing at all about the divining rod. Then I will

enlighten your primitive ignorance.

You are to understand, that, in mining districts, a superstition

prevails among the people, that some are gifted with an occult power of

detecting the proximity of veins of metal, and of underground springs of

water. In Cornwall, they hold that about one in forty possesses this

faculty. The mode, of exercising it is very simple. They cut a hazel

twig that forks naturally into two equal branches; and having stripped

the leaves off, they cut the stump of the twig, to the length of three

or four inches, and each branch to the length of a foot or something

less: for the end of a branch is meant to be held in each hand, in such

a manner that the stump of the twig may project straight forwards. The

position is this: the elbows are bent, the forearms, and hands advanced,

the knuckles turned downwards, the ends of the branches come out between

the thumbs and roots of the forefingers, the hands are supinated, the

inner side of each is turned towards its fellow, as they are held a few

inches apart. The mystic operator, thus armed, walks over the ground he

intends exploring, with the full expectation, that, when he passes over

a vein of metal, or underground spring of water, the hazel fork will

move spontaneously in his hands, the point or stump rising or falling as

the case may be. This hazel fork is the DIVINING ROD. The hazel has the

honour of being preferred, because it divides into nearly equal branches

at angles the nearest equal.

Then, assuming that there is something in this provincial superstition,

four questions present themselves to us for examination.

Does the divining fork really move of itself in the hands of the

operator, and not through motion communicated to it by the intentional

or unintentional action of the muscles of his hands or arms?

What relation has the person of the operator to the motion observed in

the divining rod?

What is the nature of the influence to which the person of the operator

serves as a conductor?

Finally, what is the thing divined? the proximity of veins of metal or

of running water? what or what not?

Then, let me at once premise, that upon the last point I have no

information to offer. The uses to which the divining fork may be turned,

are yet to be learned. But I think I shall be able to satisfy you, that

the hazel fork in some hands, and in certain localities, held as I have

described, actually moves spontaneously, and that the intervention of

the human body is necessary to its motion; and that it serves as a

conductor to an influence, which is either electricity, or something

either combined with electricity, or very much resembling that principle

in some of its habitudes.

I should observe, that I was no wiser than you are upon this subject,

till the summer of 1843, and held the tales told of the divining rod to

be nonsense, the offspring of mere self-delusion, or of direct

imposture. And I think the likeliest way of removing _your_ disbelief,

will be to tell you the steps by which my own conversion took place.

In the summer of 1843, I lived some months under the same roof with a

Scottish gentleman, well informed, of a serious turn of mind, endowed

with the national allowance of caution, shrewdness, and intelligence. I

saw a good deal of him; and one day by accident the subject of the

divining rod was mentioned. He told me that at one time his curiosity

having been raised upon the subject, he had taken pains to learn what

there was in it. And for that purpose he had obtained an introduction to

Mrs. R., sister of Sir G. R., then residing at Southampton, whom he

learned to be one of those in whose hands the divining rod was said to

move. He visited the lady, who was polite enough to show him what the

performance amounted to, and to answer all his questions, and to allow

him to try some simple experiment to test the reality of the phenomenon

and its nature.

Mrs. R. told my friend, that being at Cheltenham in 1806, she saw for

the first time the divining rod used by the late Mrs. Colonel Beaumont,

who possessed the power of imparting motion to it in a very remarkable

degree. Mrs. R. tried the experiments herself at the time, but without

any success. She was, as it happened, very far from well. Afterwards, in

the year 1815, being asked by a friend how the divining rod was held,

and how it is to be used, on showing it she observed that the hazel fork

moved in her hands. Since then, whenever she had repeated the

experiment, the power has always manifested itself, though with varying

degrees of energy.

Mrs. R. then took my friend to a part of the shrubbery, where she knew,

from former trials, the divining rod would move in her hands. It did so,

to my friend's extreme astonishment; and even continued to do so, when,

availing himself of Mrs. R.'s permission, my friend grasped her hands

with such firmness, as to preclude the possibility of any muscular

action of her wrist or fingers influencing the result.

On another day my friend took with him pieces of copper and iron wire

about a foot and a half long, bent something into the form of the letter

V, with length enough in the horizontal limbs of the figure to form a

sufficient _handle_ for either branch of these new-fashioned divining

forks. He found that these instruments moved quite as freely in Mrs.

R.'s hands as the hazel fork had done. Then he coated the two handles of

one of them with sealing-wax, leaving, however, the extreme ends free

and uncovered. When Mrs. R. used the rod so prepared, grasping it by the

parts alone which were coated with sealing-wax, and walked over the same

piece of ground as before, the wires exhibited no movement whatever. As

often, however, as, with no greater change than touching the free ends

of the wire with her thumbs, Mrs. R. established again a direct contact

with the instrument, it again moved. The motion again ceased, as often

as that direct contact was interrupted.

This simple narrative, made to me by the late Mr. George Fairholm,

carried conviction to my mind of the reality of the phenomenon. I asked

my friend why he had not pursued the subject further. He said he had

often thought of doing so; and had, he believed, been mainly prevented

by meeting with a work of the Count de Tristan, entitled, "Recherches

sur quelques Effluves Terrestres," published at Paris in 1826, in which

facts similar to those which he had himself verified were narrated, and

a vast body of additional curious experiments detailed.

At my friend's instance, I sent to Paris for the book, which I have,

however, only recently read through. I recommend it to your perusal, if

the subject should happen to interest your wayward curiosity. Any thing

like an elaborate analysis of it is out of the question in a letter of

this sort; but I shall borrow from it a few leading facts and

observations, which, at all events, will surprise you. I am afraid,

after all, I should have treated the Count as a visionary, and not have

yielded to his statements the credence they deserve, but for the good

British evidence I had already heard in favour of their trustworthiness;

and still I suspect that I should have imagined many of the details

fanciful had I perused them at an earlier period than the present; for,

it is but lately that I have read Von Reichenbach's experiments on the

action of crystals, and of what not, upon sensitive human bodies; a

series of phenomena utterly unlike those explored by the Count de

Tristan, but which have, nevertheless, the most curious analogy and

interesting points of contact with them, confirmatory of the truth of

both.

But permit me to introduce you to the Count: he shall tell you his own

tale in his own way; but as he does not speak English, at least in his

book, I must serve as dragoman.

"The history of my researches is simply this:--Some twenty years ago, a

gentleman who, from his position in society, could have no object to

gain by deception, showed to me, for my amusement, the movements of the

divining rod. He attributed the motion to the influence of a current of

water, which I thought no unlikely supposition. But my attention was

rather engaged with the action produced by the influence, let that be

what it might. My informant assured me he had met with many others,

through whom similar effects were manifested. When I was returned home,

and had opportunities of making trials under favourable circumstances, I

found that I possessed the same endowment myself. Since then I have

induced many to make the experiment; and I have found a fourth, or at

all events a fifth of the number, capable of setting the divining rod in

motion at the very first attempt. Since that time, during these twenty

years, I have often tried my hand, but for amusement only, and

desultorily, and without any idea of making the thing an object of

scientific investigation. But at length, in the year 1822, being in the

country, and removed from my ordinary pursuits, the subject again came

across me, and I then determined to ascertain the cause of these

phenomena. Accordingly, I commenced a long series of experiments, from

1500 to 1800 in number, which occupied me nearly fifteen months. The

results of above 1200 were noted down at the time of their performance."

The scene of the Count's operations was in the valley of the Loire, five

leagues from Vendome, in the park of the Chateau de Ranac. The surface

of ground which gave the desired results, was from 70 to 80 feet in

breadth. But there was another spot equally efficient near the Count's

ordinary residence at Emerillon, near Clery, four leagues southwest of

Orleans, ten leagues south of the Loire, at the commencement of the

plains of Sologne. The surface was from north to south, and was about of

the same breadth with the other. These _exciting tracts_ form, in

general, bands or zones of undetermined, and often very great length.

Their breadth is very variable. Some are only three or four feet across,

while others are one hundred paces. These tracts are sometimes sinuous

and sometimes ramify. To the most susceptible they are broader than to

those who are less so.

The Count thus describes what happens when a competent person, armed

with a hazel fork, walks over these _exciting_ districts.

When two or three steps have been made upon the exciting tract of

ground, the fork (which I have already said is to be held horizontally

with its central angle forward,) begins gently to ascend; it gradually

attains a vertical position--sometimes it passes beyond that, and

lowering itself with its point towards the chest of the operator, it

becomes again horizontal. If the motion continue, the rod, descending,

becomes vertical with the angle downwards. Finally, the rod may again

ascend and reassume its first horizontal position, having thus completed

a revolution. When the action is very lively, the rod immediately

commences a second revolution; and so it goes on as long as the operator

walks over the exciting surface of ground.

It is to be understood that the operator does not grasp the handles of

the fork so tightly but that they may turn in his hands. If, indeed, he

tries to prevent this, and the fork is only of hazel twig, the rotatory

force is so strong as to twist it at the handles and crack the bark, and

finally, fracture the wood itself.

I can imagine you at this statement endeavouring to hit the proper

intonation of the monosyllable "Hugh," frequently resorted to by Uncas,

the son of Chingachkook, as well as by his parent, on similar occasions;

though I remember to have read of none so trying in their experience. I

anticipate the remarks you would subsequently make, which the graver

Indian would have politely repressed:--"By my patience, this bangs

Banagher, and exhausts credulity. The assertion of these dry

impossibilities is too choking to listen to. The fork cannot go down in

this crude and unprotected state. It is as inconvenient a morsel as the

'Amen' inopportunely suggested to the conscience-stricken Macbeth.

Cannot you contrive some intellectual cookery to make the process of

deglutition easier? Suppose you mix the raw facts with some flowery

hypothesis, throw in a handful of familiar ideas to give a congenial

flavour, and stir into the mess some leaven of stale opinion to make it

rise; so, do try your hand at a philosophical souffle."

_Do manus._

Then you are to imagine that a current of electricity, or of something

like it, may use your legs as conductors, as you walk over the soil from

which it emanates, the circuit which it seeks being completed through

your arms and the divining rod.

Nothing, then, would be more likely, upon analogy,--the extreme part of

the current traversing a _curved_ and movable conductor,--than that the

latter should be attracted or repelled, or both alternately, by or from

the soil below, or by your person, or both.

And see, what would render such an explanation plausible? Why, the

cessation of the rotatory motion of the divining fork, on the operator

simultaneously holding in his hands a _straight_ rod of the same

substance,--that is, conjointly with the other,--offering a shorter road

to the journeying fluid, and so superseding the movable one. Well, the

Count de Tristan did this, and the result was conformable to the

hypothesis. When he walked over the exciting soil, with two rods held in

his two hands, the one a hazel fork, the other a straight hazel twig, no

motion whatever manifested itself in the former.

I flatter myself, that if you now continue to disbelieve, the fault is

not mine: the fault must lie in your organisation. You must have a very

small bump of credulity, and a very large bump of incredulity. You must

be, actively and passively, incapable of receiving new ideas. How on

earth did you get your old ones?--They must come by entail. But you are

still a disbeliever?

Bless me! how am I to proceed? I catch at the slenderest straw of

analogical suggestion. I have heard that the best cure, when you have

burned your finger, is to hold it to the fire. Let me try a

corresponding proceeding with you. My first statement has sadly

irritated and blistered your belief; oblige me by trying the soothing

application of the following fact:--

Although, in general, the divining rod behaves with great gravity and

consistency, and looks contemplatively upward, when it comes upon

grounds that move it, and then twirls respectably round, as you might

twirl your thumbs in a tranquil continuity of rotation, yet there are

some--a small proportion only--in whose hands it gibs at starting, and

with whom it delights to go in the opposite direction. I say "delights"

considerately; for it has a voice in the matter. So that a divining rod

that has been used for some little time to go the wrong way, requires

further time before it will go round right again.

The Count de Tristan found out the key to this anomaly.

He had discovered that a thick cover of silk upon the handles of the

divining fork, like Mr. Fairholm's coating of sealing wax, entirely

arrested its motion. Then he tried thinner covers, and found they only

lowered, as it were, and lessened it. The thin layer of silk was only an

imperfect impediment to the transmission of the influence. Then he tried

the effect of covering one handle only of the divining rod with a thin

layer of silk stuff. He so covered the right handle, and then the enigma

above proposed was explained. The divining fork, which hitherto had gone

the usual way with him, commencing by ascending, now, when set in

motion, descended, and continued to perform an inverse rotation.

I think this is the place for mentioning, that when the Count walked

over the exciting soil, rod in hand, but trailing likewise, from each

hand, a branch of the same plant, (which therefore touched the ground

with one end, and with the other touched, in his hand, the magic fork,)

the latter had lost its virtue. There is no motion when the ends of the

divining rod are in direct communication with the soil. The intervention

of the human body is necessary for our result.

Then we are at liberty to suppose that the two sides of our frame have

some fine difference of quality; that there is in general a sort of

preponderance upon the right side; that in general, in reference to the

divining rod, there is a superior vigour of transmission in the right

side; that _this difference_, whatever it may be, of kind or degree,

determines a current, causes motion, in the unknown fluid, which, in a

simple arched conductor, with its ends upon the soil, remains in

equilibrium. To explain the result of the last experiment I have cited

of the Count de Tristan, no difference in quality in the two sides of

the body need be assumed. Difference in conducting power alone will do.

Then it might be said, that by covering the right handle of the divining

rod, he checked the current rushing through the right side of the frame,

and so gave predominance to the left current. One cannot help

conjecturally anticipating, by the way, that with left-handed diviners,

the divining rod will be found habitually to move the wrong way.

But it will not do _now_, to let this indication of a curious

physiological element pass slurred over and unheeded,--this evidence so

singularly furnished by the Count de Tristan's experiments, of a

positive difference between the right and left halves of the frame, as

if our bodies were the subjects of a transverse polarity. I expect it is

too late to pass over now any such facts, the very genuineness of which

derives confirmation, from their pointing to a conclusion so new to, and

unexpected by their observer, yet recently made certain through an

entirely different order of phenomena, observed by one clearly not

cognisant of the Count de Tristan's researches.

I allude to the investigations of the Baron Freyherr von Reichenbach,

published in Wohler and Liebig's "Annals of Chemistry," and already

translated for the benefit of the English reader, and familiar to the

reading public.

I take it for granted, Archy, that you have read the book I refer to,

and that I have only to bring to your recollection two or three of the

facts mentioned in it, bearing upon the present point.

Then you remember that Von Reichenbach has shown, that the two ends of a

large crystal, moved along and near the surface of a limb, in certain

sensitive subjects, produced decided but different sensations, one that

of a draught of cool air, the other of a draught of warm air. That the

proximity of the northward pole of a magnet again produces the former,

of the southward pole the latter; of the negative wire of a voltaic

pile, the former, of the positive wire, the latter; finally, that _the

two hands_ are equally and similarly efficient, the right acting like

the negative influence, the left like the positive, of those above

specified. Von Reichenbach came to the conclusion, from these and other

experiments, that the two lateral halves of the human body have opposite

relations to the influence, the existence of which he has proved, while

he has in part developed its laws. And he throws out the very idea of a

transverse polarity reigning in the animal frame. Do you remember, in

confirmation of it, one of the most curious experiments which he leads

Fraeulein Maix to execute; valueless it might be thought if it stood

alone, but joined with parallel effects produced on others, its weight

is irresistible. Miss M. holds a bar magnet by its two ends. In any case

it is sensibly inconvenient to her to do so. But when she holds the

southward or positive pole of the magnet in her right hand, the

northward or negative pole in her left, the thing is bearable. When, on

the contrary, she reverses the position of the magnet, she immediately

experiences the most distressing uneasiness, and the feeling as of an

inward struggle in her arms, chest, and head. This ceases instantly on

letting go the magnet.

I will not inflict upon you more of Von Reichenbach, though sorely

tempted, so much is there in common between his Od and the influence

investigated by the Count de Tristan. If you know the researches of the

former already, why _verbum sat_; if not, I had better not attempt

further to explain to you the _ignotum per ignotum_.

And in truth, with reference to the divining rod, I have already given

my letter extension and detail enough for the purpose I contemplated,

and I will add no more. I had no intention of writing you a scientific

analysis of all that I believe to be really ascertained upon this

curious subject. My wish was only to satisfy you that there is something

in it. I have told you where you may find the principal collection of

facts elating to it, should you wish further to study them; most likely

you will not. The subject is yet in its first infancy. And what interest

attaches to a new-born babe, except in the eyes of its parents and its

nurse? I do not in the present instance affect even the latter relation.

I am contented with exercising the office of registrar of the births of

this and of two or three other as yet puling truths, the feeble voices

of which have hitherto attracted no attention, amidst the din and roar

of the bustling world. Hoping that I have not quite exhausted your

patience, I remain, Dear Archy, yours faithfully.
