The word ‘abnormal’ has been mentioned, and it is almost applicable to

the title of this chapter, as the memory must be developed beyond its

ordinary tension by constant practice to give that ease and quickness

without which second sight, or ‘clairvoyance,’ is but a sorry

exhibition. It is wonderful, however (as all matters relating to our

organisation are), what little spur memory needs to meet any strain put

upon it. Generally, ‘Where there’s a will there’s a way.’

[Illustration]

This exceedingly clever and subtle mode of conveying by words or letters

what is in the mind of one person to the comprehension of another is not

an invention of yesterday, though it has now attained to great

perfection. It was introduced into England by the Italian conjurer

Pinetti at the Haymarket Theatre in the year 1784. He announced that

Signora Pinetti, seated in one of the front boxes with a handkerchief

over her eyes, would ‘guess’ at everything imagined or proposed to her

by the audience. The clever French magician, Robert Houdin, took up the

trick, and ‘worked’ it with his son; and our own Scotch ‘professor,’

Anderson, followed in his wake, the ‘Wizard of the North’s’ daughter

being the clairvoyante in this case. Robert Heller was also a capital

exponent of second sight, with the assistance of his sister; and the

Taylors, father and son, a few years ago astonished the lieges with

their most befogging entertainment at the Polytechnic. Then M. Heriott

and ‘Little Louie’ were perhaps the most noted in this peculiar line of

business, the latter phenomenon startling even those who understood the

system by her marvellous aptitude, and the precocity that could cram

such a mass of intricate knowledge into so small a head.

We have stated that clairvoyance lies between two persons. These are,

first, the interlocutor, _who sees the articles_ hereafter to be

described by the person in collusion with him; and, secondly, the latter

gifted being, who, with eyes bandaged, can yet grasp mentally, through

the medium of the questions put, the nature of the answers to be given.

Of course, all eyes are attracted to the clairvoyante, and all attention

deliberately turned thereto, though the most difficult position is

really occupied by the one asking the questions, he having to decide

instantly as to his choice of words, and put them in such a natural,

unstudied, and off-hand style--and so quickly withal--as to effectually

_nonplus_ those unlearned in the art and mystery.

Most public performers work with a code of their own, merely taking the

idea, or ground-work, which past professors have laid down; and they

elaborate and add to their word signals from day to day as the

necessities of their position are thrust upon them. The best way, also,

for any ‘going in’ for this fascinating bit of innocent deception is to

adopt the same course, and when their code is, as nearly as they can

imagine, perfect, to study and practise diligently, and make sure they

are sufficiently ‘well-up’ and _glib_ in their respective parts, so as

to guard against being made a laughing-stock, and exposing the method at

the same time. The interlocutor should be able to put the questions

without hesitation or mistake (as, in the latter case, he runs the

clairvoyante off the rails also), and with such _nonchalance_ as to put

the spectators off their guard.

Memory, of course, plays an important part in the matter, but not quite

to the extent one might at first imagine. One hundred signals would

exhaust the list of ordinary articles carried about the person; and a

system of _grouping_--to be explained hereafter--will simplify the code,

and yet more effectually mystify an audience, as presenting less variety

in the questions put. After you have a large collection of miscellaneous

articles coded (and you can never have _too_ many, if well chosen),

numbers--signalled by means of letters, not words--and an _alphabet_ for

the spelling of surnames, etc., will require great attention; but

patience and perseverance will surmount all obstacles, and without these

you had better not attempt second-sight at all.

As we have said, most persons who ‘go in’ for public clairvoyance

compile a code of their own, and hence, after giving what we consider

the best under the circumstances, we shall mention those of two public

performers, who have given to the world their systems, one through the

pages of a leading American magazine (_Scribner’s_), the other written

by Mr. Washington Irving Bishop, who published a book on Second Sight,

containing a _résumé_ of his own professional signals; and as both of

these differ from the following, and from each other in most important

respects, they will be treated separately, so that the reader may elect

which system to pursue before entering upon the (at first toilsome, but

afterwards pleasant) path of laws.

We will now proceed to give examples of an easy code for miscellaneous

articles: following which we will have a system of grouping, a code for

numbers, and an alphabet; and we shall conclude with the application of

all these.

In the miscellaneous articles let us understand that ‘Tell’ indicates

articles of attire; ‘What,’ those taken from the pockets; ‘Do,’ those

carried in the hands; ‘Can’ and ‘Will,’ jewellery, and other articles of

Having treated of such miscellaneous articles as will generally be found

in any assemblage of persons, we may now proceed to the system of

_grouping_, which will greatly facilitate the working of the process. We

give below examples, capable, of course, of great extension.

6. Violet. | 6. Masonic.

7. Scarlet. | 7. Signet.

8. Purple. | 8. Key.

9. Brown. | 9. Split.

Etc., etc.

Christian names, towns, animals, fishes, shape, etc., can also be

arranged in the same manner.

The next process, after committing such grouped subjects to memory, is

to study a code for numbers, which you will easily acquire in one

lesson, the only difficulty you will find being in the rapid application

of it. The numbers will be represented by letters thus:--

1. t. d.

2. n.

3. m.

4. r.

5. l.

6. h.

7. k; hard c; hard g.

8. f. w. v.

9. b. p.

0. s. z.

If one figure only is required the interlocutor will ask for the

_figure_; if two figures he will ask for the _number_; if three he will

precede his question with ‘good,’ and the clairvoyant will know that he

has entered into hundreds. If there are four figures he will say, ‘Very

good,’ and that will indicate thousands; if five, ‘Very good, sir,’ or

‘madam,’ equivalent to tens of thousands. For six figures ‘good again,’

hundreds of thousands; and ‘If you please’ will act as a full stop.

Example: ‘Tell me now, if you please, what figures there are here?’--_t

m n_ (132) precede the full stop of ‘If you please,’ and the

interlocutor has dropped the ‘good,’ which would have warned the

clairvoyant that three figures had to be deciphered. Again, ‘There are

figures here. Very good. Find the numbers, can you?’ ‘Yes,’ says the

clairvoyant, taking the first four initial letters after ‘Very good;’

‘eight thousand one hundred and twenty-seven;’ and great is the marvel

of the audience thereat.

The last and most difficult problem of all appertaining to our

subject--though, luckily, the most easily dispensed with for private

performance--is the abstruse _Alphabet_, by which the clairvoyant may

learn the name of a person or gain other particulars in a way quite

unsuspected by the spectators. This is managed by taking B to represent

A, C to stand for B, and so on, always being one letter in advance of

the ordinary alphabet, save in the variations noted below. Thus--

A in the code will be B

B in the code will be C

C in the code will be D

D in the code will be E

E in the code will be F

F in the code will be G

G in the code will be H

H in the code will be I

I & J in the code will be K

K in the code will be L

L in the code will be M

M in the code will be N

N in the code will be O

O in the code will be P

P in the code will be Q

Q in the code will be R

R in the code will be S

S in the code will be T

T in the code will be U

U in the code will be V

V in the code will be W

W in the code will be A

X in the code will be Easy.

Y in the code will be Very easy.

Z in the code will be Plain.

To illustrate this, say the interlocutor has an address card with

‘William Brown’ printed upon it; he would first ask the Christian name

by the grouping process, and then, to get at the surname might say,

‘Come, speak plainly at once, if you please, the gentleman’s name?’ C S

P A O is translated into BROWN by the above system, and the answer is

correct. This transposition of letters, as we have said, is very

difficult, but if once acquired, brings the reward of being eminently

puzzling with it.

In addition to all here set forth, the ‘cue’ is frequently given to the

clairvoyant in a very simple manner as, ‘Is it large or small?’ ‘It is

small.’ ‘Plain, or with stones?’ ‘There are stones in it.’ ‘Is it gold?’

‘No; only gilt.’ ‘Does this belong to a gentleman or a lady?’ ‘To a

lady.’ Besides this, intonations, dwellings upon certain words, a

hesitating cough, or an apparently chance remark let fall to one of the

audience, conveys much to the initiated, and allows of that variation

which is so necessary in public exhibitions to prevent persons getting

at the secret. One very old and extremely useful form of

question--generally used at the close of an entertainment--is the

_Sequence_, the interlocutor touching various articles worn or held in

his immediate neighbourhood, and rapidly receiving replies from the

clairvoyant, though his questions are of the simplest. This is done by

numbering a set of such general articles as are sure to be met with.

Thus, if it is wet weather, overcoats and umbrellas will be plentiful;

if fine, sticks, parasols, and fans will be in the ascendant. Let three

or four codes be arranged for these, so as to vary the sequence and

avoid detection, thus:--

NO. 1.--FOR A FINE DAY. | NO. 2.--FOR A WET DAY.

|

1. Tell this?--A hat. | 1. Tell me this?--A glove.

2. And this?--A parasol. | 2. And this?--A cloak.

3. And this?--A programme. | 3. And this?--An umbrella.

4. And this?--An opera-glass. | 4. And this?--A locket.

5. This?--A stick. | 5. This?--A hat.

6. This?--A flower. | 6. This?--An eye-glass.

7. This?--An eye-glass. | 7. This?--An opera-glass.

8. This?--A breast-pin. | 8. This?--A chain.

9. This?--A fan. | 9. This?--A programme.

10. This?--A chain. | 10. This?--A breast-pin.

11. This?--A glove. | 11. This?--A ring.

12. And this?--A head. | 12. And this?--A head.

At a drawing-room entertainment such articles as we have here provided

for would be quite out of place, as your visitors are not likely to

carry their cloaks, hats, canes, or even opera-glasses with them. In

such cases you can arrange with your clairvoyant five minutes before

performance in what sequence you will take the more prominent articles

on or about those ‘in front.’

A ‘head’ is chosen as the _finale_, so as to bring the curtain down with

_éclat_, as the interlocutor can ask, ‘How many hairs are there on it?’

and the ready answer of, say, ‘Three thousand five hundred and

sixty-five,’ will cause a hearty laugh. Besides this, all through the

‘business’ the person who interrogates will endeavour to amuse as well

as to mystify his audience, to which end what is professionally known as

his ‘patter’ (talk) is interlarded with ‘wheezes’ (jokes), and seemingly

impromptu wit often of the most studied and built-up character. Some

public performers also employ confederates, who lend an added wonder by

producing very curious and out-of-the-way documents or other things, all

of which, having been carefully studied beforehand, the clairvoyant can

give full particulars of. The practice is, however, reprehensible; the

art is sufficiently puzzling without such adventitious aids, and the

secret is sure to leak out, when those who have been unable to fathom

the business will jump to the conclusion that much more is due to

confederacy than has really been the case.

Having gone through the drudgery, the hard study necessary to the full

comprehension of the art, we now reach a stage when it may be put into

practice, and can do nothing better than give an imaginary performance

to show the application of the principles previously laid down.

A nice little speech will introduce yourself and confederate, the usual

way being to modestly disclaim the supernatural for the wonders you are

about to work. Suppose your assistant to be a young lady, she is

blindfolded, and you proceed to business by requesting assistance from

the spectators by the loan of any article they would wish to be

described by your clairvoyante.

Then you go to work at once:--

Will you name this?--It is a ring.

Name the kind of ring?--It is a mourning ring.

Anything on it, please?--Yes, initials.

Be sure, if you please, and say what they are?--A. R.

Quite right. Can you tell this?--It is a watch.

Silver or gold?--Gold.

Anything on it?--Yes, there is a crest.

Quite correct. Now, the time, if you please, by it?--Twenty-one minutes

to one.

Very good. Can you name this?--Yes, it is a coin.

What coin?--A sixpence.

The date, if you please? (The clairvoyante knows it is of this century,

as only two letters are given.)--Eighteen hundred and eleven.

Can you tell this, please?--It is a medal.

Please name the metal?--Bronze.

Does she know? If you please to ask the young lady I have no doubt she

will tell you the campaign it is for, sir. (Here the interlocutor, in

speaking to the owner of medal, has given the cue to the clairvoyante by

_d s k_, which stand for CRI.) When the question is put, she says, ‘It

is a Crimean medal.’

Now, there is an initial here; tell me that.--M.

Look now, if you please, at the number of the regiment.--The

fifty-second.

Will you look here, please?--You now have a flower.

What flower?--Lily of the valley.

What name has this?--It is a cigarette.

What is here?--A pen-knife.

Now, how many blades are there?--Two.

Very easy. Pray view only here, if you please, and tell me the name

engraved upon the handle?--The name is _Young_.

What material is the handle made of?--Pearl.

What is this?--A pocket-book.

Anything here, please?--There is a letter inside.

Quite correct. If you please, tell me the initials of the person to whom

it is addressed?--P. B.

What is this, now?--A railway season ticket.

Can you tell the month it expires in?--Here the clairvoyante takes _c_

for the seventh month and answers ‘July.’

Very good. Be so kind, now, if you please, as to give us the number of

it?--Nine thousand and seventy-two.

Will you tell this, please?-It is a brooch.

Anything in it, please?--A child’s portrait.

Anything in it, now, at the back?--Yes, hair.

What colour is it?--Brown.

What is this for?--To smoke. It is a cigar; you can have it.

Is that right, sir? Thank you! What kind of cigar is it?--A Manilla.

Do you know what this is for?--That would also suit you; it is a cane!

Thank you, miss, you are very kind! Tell this.--That is a hat.

[Illustration: ANYTHING IN IT?]

Can you tell the colour?--White.

And this?--A parasol.

Name the colour.--Blue.

Name the material of the handle, please.--Ivory.

And this?--That is a programme.

And this?--An opera-glass.

This?--A stick.

This?--A flower.

Do you know what flower?--Yes; a camellia.

This?--An eye-glass.

This?--A breast-pin.

This?--A fan.

This?--A chain.

Find the carat?--The clairvoyante knows that _f_ stands for 8, and

answers ‘Eighteen.’

This?--That is a glove.

Do you know the colour?--Black.

And this?--A head.

Anything in it?--No.

And so the curtain comes down with a hearty laugh at the unfortunate

wight whose cranium is thus stigmatised as empty!

TWO OTHER SYSTEMS.

An ‘Ex-conjurer,’ who has treated of The Secret of Second Sight in

_Scribner’s_, says he was inducted into its mysteries twenty years since

by a Polish Jew who claimed to have invented the system; or, at least,

he had ‘treamed it’ (dreamed it), and that it was he who gave the code

to Robert Heller. As to the first of these statements, the inventing, or

‘treaming’ it, we know that the Polish Jew perverted the truth,

‘Clairvoyance’ having been practised with success before he was born:

for the second, we shall find from a portion that has gone before and

some to follow that Heller’s code differed widely from ‘Ex-conjurer’s,’

whose system may be described as the triplet and spelling code. For the

triplets he gives a long list of numbered articles, arranged

alphabetically, such as follow:--

1. Accordion, Album, Almanack.

2. Anchor, Apple, Apron.

3. Awl, Bag, Badge.

4. Ball, Bandana, Beads.

5. Bill of Exchange, Bodkin, Bonnet.

Etc., etc.

For the first article in the triplet the performer merely gives the cue

to the number; to the second he adds _here_, and to the third _that_.

To work in with these he has also a numbered alphabet, both letters and

figures being represented by certain words as below:--

Come represents A and 1

Look „ B „ 2

Hurry up, or Tell me „ C „ 3

Make haste, or Tell us „ D „ 4

Well „ E „ 5

Please „ F „ 6

Say „ G „ 7

Answer, Call, or Called „ H „ 8

Now „ I „ 9

Let me know „ J „ 10

Can you see „ K „ 11

Try „ L „ 12

Right away „ M „ 13

Do you know „ N „ 14

Go on „ O „ 15

Let us hear „ P „ 16

At once „ Q „ 17

See „ R „ 18

Look sharp „ S „ 19

Let us know „ T „ 20

Quick „ U „ 21

Will you look „ V „ 22

Do you see „ W „ 23

Be smart „ X „ 24

I’d like to know „ Y „ 25

What is it „ Z „ 26

There „ 0

I want to know „ 100

This code ‘Ex-conjurer’ illustrates. ‘_Do you see_ (W) what is this?

_Come_ (A), _Let us know_? (T), _Hurry up_ (C), _Answer_ (H).’ Surely

this seems much too roundabout a way of getting at such an ordinary

article as a _watch_! Nor does that of triplets offer great advantages,

besides which the words or phrases chosen to represent letters and

numbers come in awkwardly--and even offensively to an English ear--as

will be apparent in the following extracts:--

‘Suppose a glove is offered. This is the first article of the fortieth

triplet. The question would be “_Tell us_ (4) what this is, _there_

(0).”

‘Should the second article in the fifteenth triplet be offered, the

question would be either, “_Here_, what’s this? _Go on_ (15);” or,

“_Come_ (1), what’s this _here_? Well (5)?” and the answer in either

case a _button-hook_.’

The best thing about ‘Ex-conjurer’s’ paper is the suggestive ‘tag,’ or

speech at the end of the performance. Our aspirants for ‘clairvoyant’

fame may be able to take a hint from it:--

‘Now, how is this done? Well, I don’t mind telling you, with the express

understanding that it goes no farther. It is neither mesmerism,

spiritism, ventriloquism, rheumatism nor any other ism. It is brought

about by the action of arcane-dynamics, subjectively submitted to the

action of the passive agent, and the result, as you have seen, is a

stentonophonic reproduction of the original idea. I’m afraid it’s not

yet quite clear to some of you. Well, then, in other words, it’s a

system of mental telephony. When an article is offered to me, I seize

it; and then my assistant, he sees it. Ah! you smile--you understand it;

but, remember, not a word outside as to how it is done!’

The real second-sight, as practised by such eminent professors of the

art as Houdin and Heller, is greatly superior to ‘Ex-conjurer’s’ code,

and is contained partly in our instructions, and more exhaustively in a

work recently published. In this the code for figures is arranged

exactly in the same way as that given by us; with the addition that the

word ‘Quick’ is used to give notice of fractions. Then if the

interlocutor says, ‘Tell, now!’ the blindfolded wonder-worker knows the

initials indicate 1 and 2; therefore, by aid of the preliminary warning,

he (or she) ascertains that 1/2 is meant. Thus, if one-seventh had to be

signalled, after ‘Quick!’ the cue might be given by saying, ‘Tell

correctly, if you please, what other numbers are there.’

The work now under consideration, in addition to a code for spelling

words the same as we have given, has also codes for money, coins, cards,

colour, dates, etc., quite different from those in the preceding pages,

and well worth perusal before any particular system is fixed upon.

The book concludes with an observation that an exhibitor of second sight

will as likely as not tell you that this or that system is not the one

by which his ‘clairvoyant’ reads mentally; and here the professor may

speak quite truly. Nevertheless--and this point cannot be too frequently

insisted upon, because abnormal, and even supernatural, power is

frequently spoken of in connection with second sight--there is nothing

in the mystery that cannot be solved with a little patience and

perseverance; and you may feel satisfied that by a code and by that

alone--word-signals carefully studied and rehearsed between the

clairvoyant and the interlocutor--do all the seeming wonders come to

pass.

‘UNCONSCIOUS COUNTING.’

We cannot more suitably conclude this chapter than by referring to an

ingenious article some time ago on ‘unconscious counting’ in the

_Gartenlaube_, in which the writer, Herr W. Preyer, points out that the

ability possessed by any one of ordinary intelligence to distinguish

three, four, or even five objects at a glance, and without being

conscious of counting them, may by practice be perfected to such a

degree that it becomes quite as easy to count ten objects as it is to

count three, and that it is possible to give the exact number up to

thirty objects at a single glance. As an example of the latter

attainment, the writer points to the well-known arithmetician Dase, who

died in 1861, and who declared that he could count thirty objects of

the same kind as quickly and easily as other people could count three

or four. The truth of the assertion was often proved when Dase, with

lightning rapidity, gave the correct number of a herd of sheep, of the

books in a library, or the window-panes in a large house. The test of

how far any one can count at a glance is easily made by putting several

small objects, such as coins, pins, or matches, under a sheet of paper,

then lifting the paper for a second and looking at the objects, and,

after covering them again, give an estimate as to the number. At first

it will be found difficult to fix the number if there are more than from

three to five objects, but the eye becomes very soon accustomed to

distinguish between larger numbers, so that after a short time eight or

nine objects will be counted by the eye with the same facility. Care

should, however, be taken that the counting is not done consciously, for

that would take far too much time; the number of objects should only be

valued.

The mistakes which are at first frequently made in this guessing game

will become rarer and rarer, and almost anybody can become an expert in

rapid counting up to ten objects; after that it becomes more difficult.

The sensation, says Herr Preyer, of a person practised in unconscious

counting, when looking attentively at larger numbers of objects, is that

their number shoots rapidly through the head. To acquire this method of

counting black spots should be made on white square pieces of cardboard,

first symmetrically and in small numbers, as, for instance, the

following:--

[Illustration]

Afterwards their number may be increased and their position altered. It

will also be good practice to open a book, cover part of the page,

rapidly look at the lines left uncovered, and to guess at their number.

It is astonishing how soon the eye gets accustomed to the numbers. The

more advanced ‘unconscious counter’ should practise on spots not

regularly arranged, which is much more difficult at first. Herr Preyer

concludes his interesting article with the remark that unconscious

counting, like all other oft-repeated processes, such as lifting the hat

as a token of salutation, becomes at last an entirely mechanical

process.

CHAPTER LVIII.--SPIRITUALISM AT HOME.

BY DR. STRADLING.

Spiritualism does not in reality mean conjuring; of course you all know

that. But the term has now come to be familiarly applied to a certain

class of performances, without any pretence of supernatural aid or

deceit, and arose in this way. Some twenty-five years ago several

people--the celebrated Davenport Brothers among them--appeared in this

country and America, and gave entertainments at which they exhibited

some very extraordinary and, at that time, novel effects of a magical

character, the leading features being their release from cords which had

been bound, knotted, and sealed upon them by members of the audience,

leaving the knots and seals unbroken; causing inanimate objects to fly

about and musical instruments to sound when it appeared impossible for

any one to have touched them; and divining numbers and sentences which

had been written down privately, unseen by them.

These things they professed to do, not by their own skill and dexterity,

but by the aid of ‘spirits’ over whom they declared themselves to have

control; and the whole was accompanied with a lot of nonsense in the

shape of luminous ‘manifestations’ in the air when the gas was turned

out (for darkness was indispensable), and ‘spirit-writings’ on slates

and sheets of cardboard--messages, supposed to come from the unseen

world, scrawled in a shocking bad hand that any boy would be ashamed of!

Nevertheless, a great deal that was done was new and very clever, and

had it only been honestly acknowledged to be the result of

sleight-of-hand, the performers would certainly have earned and well

deserved the reward of success.

But though people go to see conjuring perfectly prepared and willing to

be deceived--if that can be called deception which is openly avowed to

be misleading--they do not like to have their common sense insulted by

irreverence, such as these spiritualists were guilty of in pretending to

call up the dead; and a strong feeling of indignation soon set in

against the imposture and all who practised it.

Clever as the exhibitions were, also, one or two slips were made which

were fatal to them, though it does not ruin a straightforward conjurer

to have a trick accidentally discovered now and then. For instance, on

one occasion, a dreadful fiery hand, pale and deathly, though glowing

with light, was seen sweeping through the air, high overhead, rushing

from end to end of the room with a swiftness that no being could have

possessed unless provided with wings, and at times descending to give

somebody a cold, clammy touch on the cheek. One, bolder than the rest,

had the courage to seize this hand, and, in spite of all opposition,

insisted on retaining it until the gas was turned up, when the

spirit-hand was found to consist of an old white kid glove, stuffed with

damp tow and rubbed with phosphorus, suspended at the end of a cord, and

waved overhead by means of a long fishing-rod, which folded up in short

joints adapted for the ‘medium’s’ pocket!

Furthermore, professional conjurers were put on their mettle, and very

quickly showed that they could do, not only the same things, but much

more wonderful ones of a similar character in the full glare of the

gaslight, without any aid from spirits. The mysterious cabinet, which

took such a prominent part in the Davenports’ programme, was soon

robbed of its mystery; and in 1865 Professor Pepper--whose name

you will remember in connection with ‘Pepper’s Ghost’ at the

Polytechnic--invented and patented a piece of apparatus, such as the

spiritualists had never dreamed of, called the ‘Cabinet of Proteus.’

The ‘mediums’ have long since retired into comparative obscurity, and

now limit their manifestations to displays in private; but they still

have a number of followers who are ready to believe that what occurs at

these gatherings is really the work of invisible spirits, because they

do not see how else it can be done. I heard a famous conjurer say the

other day, at the close of his entertainment, ‘If I have been able to

deceive and perplex you; if I, telling you beforehand that the effects I

was about to produce are the result of mere trickery and quickness of

hand, challenging your detection in the full light of the room, have

succeeded in making you, watchful and alert to find me out, imagine that

black was white, and have convinced you that seeing is _not_ always

believing, how much more might a skilful impostor mystify a lot of

superstitious people, already frightened out of their wits by fear, in a

dark chamber with accomplices!’

When, therefore, we read now of a spiritualistic _séance_ given in

public, or of Messrs. Maskelyne and Cooke’s spirit manifestations, we

understand the term to have reference to feats of that description,

which originated in the above manner; and in telling you how you may

exhibit a little ‘Spiritualism at Home’ to your friends, you will now

see that I do not intend that you should even pretend to have anything

to do with supernatural causes, but only to perform some very

astonishing tricks on the same principle as you have been taught to make

a halfpenny vanish and reappear.

Modern effects of this kind, as they are presented on the stage, demand,

as a rule, not only great dexterity and years of practice, but the use

of elaborate and costly apparatus and the help of skilled assistants.

All sorts of ingenious mechanism, for which patents are often taken

out--electricity, pneumatics, chemistry, optics, magnetism, and nearly

every science and art--are pressed into the service, and the floor, the

walls, the platform, and the ceiling may be riddled with wires and traps

and springs, for anything you know to the contrary; or the lady and

gentleman--or even the little boy or girl--sitting beside you may be

confederates. Now, if you will carefully carry out the directions which

I am about to give you, you will be able to do the following

things--founded on the very essence of professed spiritualism--viz., the

rope-tying, the ringing of bells and beating of tambourines without

visible agency, mysterious writing, and secret reading--in your own or

anybody’s room, in the presence of any number of spectators, in the full

light, without preparation, without practice, without assistants or

accomplices, without sleight-of-hand, and without any apparatus, except

(for one trick) a very simple article, which any boy can make for

himself in a few minutes.

Let me first describe the _effect_ of the performance, without any

explanation as to how it is done--that is to say, as it will appear to

your audience. You give some one a piece of ordinary tape or ribbon,

which they can examine as closely as they please. One end of this

ribbon, which is about two feet and a half long, is now tied firmly

around your wrist. Placing your hands behind your back, you then allow

the other end to be fastened around the other wrist in like manner. Thus

your hands are tied behind your back, each being secured separately, to

prevent the possibility of either slipping out, and the knots, or ends,

are then sealed with sealing wax and stamped with a crest or private

mark for identification afterwards. Sitting on a chair at the farther

end of the room, with your back turned to the company, you pass your

arms over the back of the chair, so that all may see the ribbon and

seals; and while in this position you invite a spectator to step forward

and tie his handkerchief around the cross-bar of the back of the chair,

including the ligature which joins your two wrists, knotting the

handkerchief tightly and sealing it as well.

So that you are now practically tied to the chair, with your hands

fastened together behind you. Two of your audience then hold up a

table-cloth or open newspaper in front of you as a temporary screen--of

course giving their word not to look behind while so doing; a few bars

of mysterious music are played on the piano; in a minute, at a signal

from you, the newspaper is snatched away, and you are seen sitting in

precisely the same attitude and bound as before, but with your coat

removed and lying across your knees! Knots and seals are all discovered

on examination to be firm and intact, nor does the cross-bar or any

other portion of the chair ‘unship.’

No assistant could have approached you without being seen, and your coat

can be passed round, to show that there is nothing peculiar in its

construction. You can, if you please, be screened once more for a

minute, and put it on again, and the second time you may be found

standing beside the chair, entirely free from it, yet having your hands

secured as tightly as ever behind your back, and leaving the sealed and

knotted handkerchief undisturbed around the cross-bar. This, performed

in a dark cabinet, was Ira Davenport’s great feat.

But you may elaborate this much further, and just as easily give some

‘manifestations’ which are truly astounding. The principle which lies at

the bottom of it all is very little known, even among professional

wizards, and not one person in ten thousand would as much as guess at

it. Your hands are tied and secured to the chair in the same manner as

last described; but now, in addition, you have your legs and ankles

bound to the legs of the chair, and a rope or strap passed around your

body. Perfect strangers may do all the tying, and everything is sealed.

This time you had better have a regular screen--a sheet or tablecloth

thrown across a clothes-horse makes the best possible--and let it be so

arranged that, while hiding your body, it leaves your feet visible. They

can therefore _see_ for themselves that you never move from the chair

for a single instant, even if it were possible to do so. Handkerchiefs

around the ankles will be better seen than cords or ropes. The screen

must stand well out in the room, so that there may be no suspicion of a

confederate ‘lending you a hand’ from any door. On a small table,

concealed by the screen, but _quite out of your reach_, even if your

hands were free, are placed a bell, a tambourine, an umbrella, and a

slate or sheet of blank paper.

A few seconds after the clothes-horse has been pulled in front of

you--or rather _behind_ you and in front of the audience, for you are

sitting with your back towards them--the bell is heard to ring

violently, and the umbrella, _open_, rises above the screen, dancing up

and down in time to the music of the piano, presently hitching itself on

the top rail. Then your coat comes flying over, and the tambourine is

thumped and rattled, the bell never ceasing to ring energetically.

Finally you give a shout, as agreed upon, the screen is quickly drawn

aside, the bell and tambourine are seen to fall from _somewhere_--where,

nobody can tell--and roll clashing and clattering over the floor before

the eyes of all. The umbrella is open, your coat is off, the slate or

paper is covered with writing. Yet not a single knot is untied nor a

single seal broken: you are in exactly the same position as at first,

and none of the articles show any trace of wax or thread. Bear in mind,

too, that the spectators have had your feet, the legs of the chair, and

those of the table, in full view the whole time, and will have seen that

none of them moved in the slightest degree.

The mysterious reading or calculation may be done in conjunction with

this, or as a trick by itself. When you have the method which forms its

foundation, you can arrange its effect in a dozen different ways,

according to your fancy. Perhaps the best and least complicated form is,

before you are tied up, to pass round half a dozen slips of paper or

cardboard, with a lead pencil, requesting each of the six people to whom

they are distributed to write a number--any number they please--thereon

in legible figures, secretly. The slips are collected in an envelope,

fastened, and brought to you, and you entrust them to the ‘best

arithmetician’ in the room, when the rest of the audience have decided

who that lucky individual may be, to be opened and added together,

without declaring their total or mentioning a word about them, whilst

you are behind the screen. Then the number discovered on the sheet of

paper or slate will prove to be the exact amount, or the tambourine may

fly over and fall before them with the sum total mysteriously inscribed

upon it--even before the arithmetician has added the numbers together.

Or, as I say, this may constitute an experiment of itself, and the total

may be found on a card hitherto blank, or written inside the lining of

somebody’s hat, which is placed upon the owner’s head and retained there

before the slips are even passed round. Or, before the total is

declared, it may be written down privately by the one who has made the

addition, the cards burnt, and the ashes rubbed on the performer’s bare

arm; when, in the midst of the bluish smudge they produce, the amount

will appear in figures of inky blackness.

So much for ‘Spiritualism at Home,’ as viewed from the ‘front.’ Now come

behind the scenes and learn the _modus operandi_. It will not involve a

very lengthy description.

The whole of the coat-stripping, bell-ringing, tambourine-beating,

umbrella-opening, and other manœuvres executed under shelter of the

screen depend upon the fact that it is actually possible to remove one

hand from the tape or ribbon which is bound around the wrist and to

replace it again without untying the knot! To understand this, just tie

one end of a piece of cord around anything--say, the leg of a chair;

that will, no doubt, be firm and secure enough. But now proceed to

fasten the other end round the other leg, and you will perceive, on

considering the matter, that you have _only one end to tie with_,

instead of two as before. The other end is fixed, and cannot be made

use of, so that, tie as you will, you can only form a series of

loops--in nautical phrase, ‘half-hitches’--around one straight piece.

What is the consequence? Why, that these loops, being nothing more than

so many rings strung on the line which comes from the other leg of the

chair, can be slid backwards and forwards along it. When you have tied

the second leg up tightly and neatly, and to all appearance as securely

as the other, you have only to slip these rings, or knots, back towards

the first leg, to allow of the second being drawn out, and on replacing

it again you slide them back against it as firm as ever, having untied

nothing.

This is precisely what you do with the last-tied wrist behind the

screen, except that it is much more easily accomplished in this case

than with the leg of a chair, because you can relax the long piece, and

so give yourself more space by bringing the hands a little nearer to

each other. It is difficult to comprehend this from a written

description, and a diagram would be of little use to illustrate it, but

you will see it readily on following out the successive steps just

mentioned.

Let us go through the trick for the sake of noting one or two little

points which require some care. Tape is better than string or rope, and

ribbon is best of all, because, from the silk in its composition, it is

slippery, and will glide smoothly, without requiring to be tugged, or

being in danger of getting ‘jammed.’ The first wrist is tied before you;

the manner in which it is done does not concern you, though you could,

if need be, ‘capsize’ an ordinary knot--reef or granny--and convert it

into the same condition as that applied to the second wrist. This,

however, will be quite unnecessary. Nevertheless, you had better observe

the mode in which this first knot is tied, for this reason: it would be

possible for some skilful person--a sailor, for instance--to put a

‘clove hitch,’ or some other nautical complication, around the second

wrist, which could not be manipulated in the way described. You are not

likely to meet with anybody who will treat you so, and of course, in

speaking of knots, one means the ordinary arrangements, such as nine

hundred and ninety-nine people out of a thousand will tie.

But if you _should_ find somebody who is clever and ill-natured enough

to try to baffle you, let him tie away to his heart’s content on the

first wrist, then, ‘to show there is no deception or confederacy,’ move

on to some one else for the second. The best way is always to go to a

lady; probably she will only tie a simple bow at first, which you will

pull open at once, making a great merit of scorning to take advantage of

such a thing, and requesting, for your own satisfaction, to be secured

in a manner which will leave no doubt in the minds of the audience,

etc., etc. The second wrist is tied behind your back, and when both are

thus encircled a straight piece, about one foot in length, will connect

the two hands.

But how about the seals? You will perceive that the knots in both cases

lie close against the flesh, and it is only possible to put on the

merest dot of wax--_and this on the loops themselves_--without burning

the skin. Thus they will carry the seal unbroken with them as they slip

backwards and forwards. But since there is, even so, a chance of your

getting scorched, it is better in every way to request that an end of

about two inches long be left in each case--you can adjust it yourself

with the first wrist, as a pattern for the second--explaining your

reason, and have this sealed down to the long piece which intervenes.

You can have the end of it sewn as well if you like. The more you are

apparently hampered by precautions and impossibilities the more

wonderful and impressive the feat becomes, and it must be evident to all

that the knots cannot be untied when the ends are made fast without

breaking the seals.

The handkerchief around the cross-bar of the chair, like the

ankle-fetters and ropes around the body in the more elaborate version of

the trick, are merely for the sake of effect, and are of no consequence

to you at all; but be sure to draw just as much attention to these as

the other, and lay as great stress on their being sealed.

Now I think you see how to proceed. Directly you are hidden by the

newspaper catch hold of the knots last tied with the fingers of the

opposite hand, and slide them gently outwards from the wrist towards the

seal. This will enlarge the loop by a good inch or an inch and a

half--more than enough to enable you to withdraw the hand. The arms are

now free from one another, the ribbon with the enlarged loop at the end

of it dangling from the first-tied wrist. This is pulled through the

loop of the handkerchief, the coat quickly removed, and the whole

process then simply reversed--the arms brought together behind the chair

again, ribbon passed through loop of handkerchief, hand passed into the

noose, and knots slipped back to the skin, tighter than ever. Putting on

the coat is managed just in the same way. If you want to appear freed

from the chair, do not pass the ribbon within the handkerchief in

replacing your hand; or you may produce a most puzzling result, if you

like, by twisting it around the cross-bar instead.

Do not be ‘flurried’ or over-eager. Remember, if you took half an hour

about it the performance would be just as mysterious and incapable of

explanation. You may, however, _apparently_ shorten the time employed in

its execution by asking some young lady to oblige you with a little

appropriate music as soon as the screen is raised. ‘Something very

solemn and soothing--a little slower, if you please; thank you, that

will do nicely’--working away all the time. ‘Now then, who’s got a

watch? You have, sir? Has it a second-hand? Now, kindly tell me when one

minute has expired,’ and so on, according to the amount of delay you

require. Always take care that there is no light behind you, or the

screen will become transparent; and place your chair where you will not

be reflected in any looking-glass.

But the bell-ringing and tambourine-beating, combined with this, will

absolutely astonish your friends, for this is what fills the public with

greater wonder than anything else, even when performed by professional

conjurers amidst all the appliances of a regular stage. For this you

will want some instrument which can lie folded up inside your waistcoat

(not coat); it must therefore be not more than a foot long when not in

use, but capable of being expanded to such a length as will enable you

to reach the articles on the table with it while still sitting on your

chair--the distance is not likely to be more than four feet at the

outside. Indeed, it is not necessary to have it so much, for everybody

will be able to see that you do not move from the chair. This may

consist either of a sort of fishing-rod of four pieces, or a jointed rod

made to fold up by hinges on the same principle as a pocket foot-rule,

so that the joints bend in one direction, but are stiff in the other. If

either of these is used, there must be a crook at the end to hook up the

umbrella and tambourine, and the bell must have a loop of string

attached to it, unless you choose to have a line running through an eye,

as with a regular fishing-rod, and angle for the articles with a noose.

Much better, to my thinking, is that little bit of apparatus--commonly

sold with boxes of toy-soldiers-known as ‘lazy-tongs.’ It is formed, as

I dare say you know, by a number of =[X]=-shaped slips of wood, joined

together at the extremities in a sort of lattice (=[XXXX]=). The rivets

are loosely fixed, so that by pressing the arms of the end =[X]=

together the whole shoots out to its full length, and, by separating

them again, the ‘tongs’ fold up. You will see the same action

exemplified in those ornamental lattice-fences which are made to

surround flower-pots in a drawing-room. By means of this, the things on

the table can not only be hooked, but pinched up if required, and can be

rattled about there before they come near your hands. If writing-paper

is used instead of a slate, a pellet of bees’-wax or a drawing-pin must

be fixed at the end of the tongs.

Having freed your wrist as before, get hold of the bell first and seize

the handle between your teeth, where you retain it the whole time,

ringing it by shakes and nods of your head. Next bring over the umbrella

and open it, causing it to appear above the screen and dance as

described; you may even shoot it out beyond the side of the screen on

the lazy-tongs, far beyond your arms’ reach, ‘even if they were not tied

behind your back.’ Hang the umbrella on the top rail of the

clothes-horse, and divest yourself of your coat, flinging it over. Then

fetch the tambourine, ringing the bell as hard as you can all the while.

Beat time to the piano for a few moments, making the umbrella dance

again in unison. The tongs must hang on your arm when not wanted, for do

not forget that the audience have a full view of the floor, and that if

you drop anything you cannot pick it up again. To drop the lazy-tongs

would reveal the secret entirely, but the other articles do not matter

so much. Now if you are going to do any writing, get the paper or slate,

the pencil will be in your waistcoat-pocket, and you can use the

tambourine as a desk. Finally, tuck the latter under your chin, and roll

the edge of the bell to and fro upon it while you tie yourself up again;

give a shout, as the prearranged signal for somebody to remove the

screen, releasing the bell and tambourine at the same instant. Down they

fall, and go rolling and jingling over the floor before the spectators,

and there you are, bound and strapped, as close a prisoner as ever!

I said you could do all this without practice, and so you can, since

there is no sleight-of-hand or dexterity involved. But you had better

rehearse once or twice privately before giving an exhibition, to see

that you have everything in working order; by so doing you will acquire

confidence, and produce your effects one after the other in a much

shorter space of time, while you may hit on many others. For instance,

if your table is one of those small, light, ornamental affairs resting

on a single stem, you might cause it to rock violently by means of your

tongs, and to ‘walk’ from one edge of the screen to the other, the

audience being able to watch the motion of its feet. If you like you may

even have your elbows secured to the back of the chair, and will still

be sufficiently at liberty to do all but take your coat off. The great

thing is to make all the effects fit in with one another compactly.

Some years ago a noted conjurer introduced a feature into his

entertainment which, for a time, startled the public. He allowed himself

to be handcuffed by any policeman present who would fetch a pair of

Government handcuffs for the purpose; these were locked, and the key

retained by the constable or some other member of the audience. The

performer then stepped behind a curtain, and presently came out, still

manacled, but minus his coat. But after a bit it suddenly occurred to

some one that all the Scotland Yard handcuffs issued to the police were

made on the same pattern, and that the magician had only to unlock them

with a duplicate key kept in a little pocket at the back of his

waistcoat!

Now for the ‘Mysterious Addition,’ or ‘Spirit-writing.’ Six small pieces

of cardboard or paper are distributed, and those to whom they are given

are requested to pencil some number consisting of any figures they

please. Let these people be separated as much as possible, ostensibly to

show that there is no collusion, but really to prevent any comparing of

notes; enjoin strict secrecy, too, as to the numbers written, for

similar reasons. Let somebody collect the folded slips in one of those

small envelopes such as are used for ‘Your change, with thanks,’ in

shops, fasten it, and bring it to you. You go back to your table and lay

it carelessly thereon, bringing forward your piece of ribbon instead, as

though to save time; and while the first knot is being tied you ask, Who

is the best arithmetician in the room? This being decided, you go back

and get the envelope before the second wrist is tied, giving it to him

with a pencil and plate, and bidding him, when he has added the six

numbers together, to say nothing, but make a private memorandum of the

amount, burn the slips on the plate, and keep the ashes for you.

In laying the little envelope ‘carelessly’ on the table, where you have

your ribbon, candle, matches, plates, rope, sealing-wax, etc., in

readiness, you are careless or careful enough to place it so that it

shall be hidden by the rim of the plate, side by side with another

little envelope of precisely similar appearance, also concealed by the

margin of the plate. This second envelope contains six slips of paper or

card, too, and on these you have written--in pencil, and in different

‘hands’--six numbers, the total of which is known to you. Let us suppose

that you have put 209, 23, 1000, 7, 51, and 346; the sum of these is

1636, and is discovered to be such by the arithmetician--who, of course,

is not chosen from among the six, ‘to prevent any deception,’ but is

wholly independent of them--when you hand him this second envelope

instead of the genuine one. Behind the screen, therefore, you have only

to write 1636 on the slate or tambourine, which will be found to tally

with his memorandum. Or, if you are doing this trick by itself, paint

1636 on your arm in glycerine with a fine brush, and let it dry in

before commencing. This being transparent, will be quite invisible till

the ashes are rubbed in, when the number will stand out jet black. You

can vary this in a dozen ways, by writing the number and concealing it

somewhere beforehand, since the amounts which the audience put down on

_their_ slips do not affect _you_ at all. In every case it is well to

have the slips burnt, and you can ask to have the numbers restricted

within the hundreds--that is, in three figures--on the plea that it will

otherwise be tedious to add up. Make your own amounts rather larger than

those given above by way of example.

Of course no comparisons are made, or, even if any two or three did

compare, no one can dispute the accuracy of the total, for no one knows

what the numbers were beyond his or her own figures; and the addition is

beyond suspicion when made by a representative whom the audience choose

for themselves. But, you will ask, how is the first envelope concealed

when you take up the plate to receive the ashes? Simply by having two

plates, as though to provide against contingencies, and giving the

upper one, using the other to stand the candlestick upon if you like,

and pushing it back a few inches casually to cover what was behind it.

If you prefer it, you may take out your handkerchief and draw it lightly

over your arm after it is bared while the slips are being collected;

then throw it casually on the table beside the plate to serve as a mask;

or you may have a few spare handkerchiefs ready on the table and

dispense with the plate as a means of concealment altogether. You will

draw attention to the fact that you have handkerchiefs wherewith you may

be secured if nobody will lend them, but that of course you prefer to

use borrowed ones. Conjuring tables with traps and shelves are utterly

unnecessary for small articles which cannot be seen by those seated a

little way off if the smallest projection intervenes.

Always have everything ready and in its place before commencing. If you

have to leave the room for anything in the middle of a trick your

audience suspect something, and the effect is spoiled. Make a list:

candle in candlestick, matches, sealing-wax, ribbon, scissors (for

cutting the knots at the conclusion), rope, strap, chair, tablecloth or

newspaper, screen, bell, umbrella, slate, tambourine, lazy-tongs,

pencil, small envelope, slips, plates, duplicate envelope. The last need

give you no anxiety, you can have it in your match-box, if you please,

and coolly put it in the desired position while standing with your back

to the people, ‘setting’ your table before commencing.

Talking of ‘spirit-writing’ reminds me of an anecdote--a problem put

before me the other day by a post-office boy which might well have

perplexed the cleverest of conjurers. I was sending a paper which I had

just written to the Editor of the _Boy’s Own Paper_, but was uncertain

about the amount of postage, so I stepped into the office to have it

weighed and get stamps. Manuscript for the press goes at book-post rate

if the ends are left open, and ‘Manuscript’ is marked on the wrapper.

‘Printed matter?’ asked the youthful and conscientious official

(evidently a new hand) to whom I handed the document, as he prepared to

put it in the scales.

‘No; manuscript,’ I replied. ‘But it’s all the same; book-post tariff

covers it.’

The boy was obviously not quite satisfied on this point, for, having

weighed the packet, he referred to a big book, doubtfully.

‘Twopence-halfpenny,’ he presently decided; ‘it will go for

twopence-halfpenny, _provided there’s no writing inside_!’

SECTION XI.

DIVERSIFIED DIVERSIONS.

YOUNG DOBBS’ HAT.

[_A tragic story for Magic Lantern or Shadow Show._]

[Illustration: 1. When Dobbs was a little boy, he was not so particular

with his hats as he was when he grew up to young-manhood. For instance,

on the very day he wore his first tall one he encountered a magnificent

specimen of the cabbage butterfly.]

[Illustration: 2. Now he much wanted a cabbage butterfly to complete his

collection, so he made straight at it. In the pursuit his hat suffered.]

[Illustration: 3. So did he when he got home! As for the butterfly, I

have every reason to believe it died a natural death some time later.]

CHAPTER LIX.--FIRE-BALLOONS AND GAS-BALLOONS: HOW TO MAKE AND USE THEM.

BY THE LATE DR. SCOFFERN.

I.--THE PRINCIPLE OF BALLOONING.

Every boy at some time or other, I suppose, has felt himself

irresistibly drawn towards the subject of toy-balloons; but first

unaided experiments in that direction seldom prove altogether

satisfactory, or maybe even pleasant. It is my intention, therefore, to

go into the matter thoroughly and practically, explaining all about

fire-balloons, and telling you at once how to make and use them.

If a thing--anything--be placed in the midst of any other thing lighter

than itself, and if thing number two be not a solid, but either a liquid

or a gas, both which permit of motion in any direction, then thing

number one will ascend.

If you want to have this demonstrated, just plunge a cork down into

water and see what happens. If instead of a cork you were to take a lump

of iron--say a cannon ball--then the very idea of such a heavy material

floating would seem to you ridiculous. It will float, nevertheless, not

in water, truly, but in any fluid of greater weight than itself.

Quicksilver, otherwise called mercury, is such a fluid, and the very

experiment I have supposed you to perform for curiosity is actually

turned to practical account by artillerists when they wish to ascertain

whether a cannon ball is equally heavy on every part of corresponding

size around the centre. If not equally heavy, then spots marked upon it

will not float upwards equally well. If any particular spot insists on

turning downwards, then the result proves that one side of the round

cannon ball (please excuse the word side, a sphere really has no sides)

is heavier than the rest.

But to return to our balloons. Well, please remember the globe on which

we live is surrounded by an atmosphere--air we call it--and also please

understand this atmosphere has weight; consequently it follows that

anything lighter than the atmosphere will ascend in the atmosphere. In

this we have the whole theory of balloons and ballooning.

The air has weight,--yes, more than you have been accustomed to think,

perhaps. Just take the pen or pencil and mark out a piece of paper one

square inch. Having marked out this, you are to understand that the air

presses upon it with a force of about fifteen pounds. I say _about_, for

the reason that atmospheric pressure is not always exactly the same.

Sometimes it presses rather more, at other times rather less than

fifteen pounds, but still the variation is not great.

Thus, air has weight, and you also know that air, being a fluid, permits

objects to move about in it, so it follows that if we can find anything

number two lighter than the air, it will ascend in the air. We shall

look in vain amongst liquids and solids for thing number two, all being

heavier than air; but of gases lighter than air there exist several. Why

not use them? We can use some of them, and we presently will; but it

stands to reason that we can no more use a gas for lifting a weight up

into air without first putting the gas into a bag, than we can use a

horse for carriage-draught without first putting a collar round his

neck, then attaching shaft and traces: no, indeed, not so well even,

because in a case of emergency a carriage might be fixed to the horse’s

tail!

The very simplest form of balloon is a soap-bubble. Most of us have

probably at some time or other amused ourselves by blowing soap-bubbles,

without perhaps troubling ourselves to understand the whys and

wherefores of the case.

Why is it that a soap-bubble blown with air from the lungs ascends? You

will tell me perhaps that it ascends because the air which comes from

the lungs is of a lighter ‘nature’ than the atmosphere No, indeed,

instead of having a lighter it has a heavier nature. Though air which

comes out of the lungs is by ‘nature’ _heavier_ than air which goes into

the lungs, yet at the same time it is warmer, and for the reason of that

warmth it remains during the existence of the warmth practically

lighter.

This circumstance being remembered, you will at once understand why it

is that a soap-bubble, even if it lives--so to put the case--long

enough, does not continue to ascend as a balloon would have continued,

but first slackens in its upward course, then descends, the reason of

descent being the cooling of the air within it. If you had been clever

enough to measure that soap-bubble twice, first at the very moment of

rising, next at the last moment of setting, you would have found the

warmer bubble to have been the larger.

If you were to blow a thin bag full of air, you would not expect it to

ascend, on the supposition, that is to say, that the bagged air and the

free air are of one and the same temperature; but if you could manage to

make the bagged air hot, and keep it hot, then you would get lifting

power. This is exactly what is done in the Montgolfier, or fire-balloon.

The reason of this seems very simple when one comes to think about it,

yet the Brothers Montgolfier, inventors of the fire-balloon, did not

exactly see the true science of the balloon that bears their name. They

appeared to have reasoned somewhat in the following manner. A wreath of

smoke ascends, therefore smoke must be lighter than air; therefore a bag

filled with smoke, and kept full of smoke, should also ascend, supposing

the bag to be made of sufficiently light materials.

If the Montgolfiers had said, instead of smoke, hot air, they would have

truly represented the fact.

They made a bag of canvas, and they lined it with paper. Under the neck

of this bag they hung a sort of fire-grate, and underneath this, but

within reach of it, a car. Impressed as they were with the smoky notion,

one of their first cares was to feed the fireplace with some variety of

fuel that would yield abundant smoke. Chopped straw, slightly damped and

mixed with wool, was one of the favoured combustibles.

Fire, or Montgolfier balloons, large enough to take up sky travellers,

are no longer used; air-balloons, or, as it would be more proper to call

them, gas-balloons, being more convenient and at the same time more

safe. Toy fire-balloons are, however, still made and let off as a pretty

firework, and I shall now describe the best and easiest ways of making

them.

II.--FIRE-BALLOONS AND THEIR CONSTRUCTION.

They may be constructed of any size; but an overgrown fire-balloon,

according to my experience, is seldom satisfactory, and never returns

value for the money expended in making it. As a boy I was a great

fire-balloon maker. I have made them of various sizes; at length,

however, coming to the conclusion that three sheets of tissue-paper,

pasted end to end, then cut into shape and joined, make a balloon quite

large enough to manage, and also large enough for every ornamental

purpose.

‘Cut into shape,’ did I not say the paper was to be? Well, what sort of

a shape? Perhaps I need not tell you that a perfectly globular bag will

hold more than any other shaped bag you could make out of a given

quantity of paper. A peeled orange or lemon will give the very best idea

of the general shape of the gussets of a balloon. Speaking generally,

the narrower you cut the gussets of your balloon the neater will be your

turn out; but of course, if narrow gussets be employed, more of them

will be needed than if you employed wide gussets. Neatness of

manufacture is of no account when brought to bear on a toy firework

that, after a few moments of ascent, reveals itself to lookers-on merely

as a patch of moving light.

[Illustration: Fig. 1.]

[Illustration: Fig. 2.]

After many trials, I came to the conclusion that when using

tissue-paper, three sheets pasted narrow edge to narrow edge, eight

gussets were enough. Occasionally, however, I would slightly elongate

each gusset by attaching one of the little corners _a_ or _b_, and

fixing it at _c_. Of course the pieces _a_ and _b_ have to be cut away

in any case, else the necessary gussets could not be made.

With regard to the exact shape of a finished balloon, always remember

that the more nearly globular it is the more gas or air will it hold,

and the more stable will be its flight. Assuming you to have pasted end

to end three sheets of tissue-paper, with the little bit (_c_) added to

the top part over and above, I recommend you to divide, mentally at

least, the three sheets and bit added, rectangle, into four parts. Of

these the two middle parts need not be cut or trimmed at all. All the

trimming needful can be done on the two end parts. Another thing--do not

give any care to bringing the crown, or summit, of the balloon to a

point. You will have to paste on what we call a round summit, or crown,

at any rate, under which circumstance your bringing all the gussets to

one terminal point is of no consequence. In cutting out the gussets,

this is best done on the double, which will ensure symmetry.

You will tell me, perhaps, there is a sort of regularity about my

preliminary work that does not please the eye. You would like, perhaps,

to make a graceful balloon like Fig. 3.

Better not. Do you not see what would happen when you came to set light

to the fuel suspended under the mouth of the balloon? The flame would

almost certainly strike against the paper of the narrow neck, and

presently the whole balloon would be in a blaze.

Having cut out your gussets, the next thing is to join them. First as to

cement. Use thin paste or gum water, which you please, and employ a

camel-hair, or better, a sable-brush, to spread it. Half an inch lap is

quite enough; and when the necessary paper junction has been made, I

like to dry my work at once by means of a laundress’s smoothing iron.

Taking this precaution, you will have no sticking at spots where

sticking ought not to be.

A final word now about the best way of bringing the edges of your

gussets together. The line diagram here given will make all

comprehensible: _a_ and _b_ represent, we will say, two gussets.

[Illustration: Fig. 3.]

[Illustration: Fig. 4.]

[Illustration: Fig. 5.]

[Illustration: Fig. 6.]

The edge of _a_ is alone to be gummed or pasted to about half an inch

wide; the corresponding edge of _b_ is then to be bent down upon the

cemented edge of _a_, and dried at once with the laundress’s hot iron;

not laid naked upon the paper, but having a thickness of flannel

interposed. Proceeding thus all round, you will at last finish your

balloon all but the crown pieces and mouth stiffener. For a balloon of

the dimensions recommended, I would advise you to paste on a crown piece

of about a foot diameter. Don’t make it of tissue-paper, but of soft

whitey brown paper, and in the middle of it paste a loop of calico,

something similar to the loop of a saucepan lid. The utility of this

will be found out when you come to let off your balloon.

As a mouth stiffener I prefer a circle of thick iron or brass wire to

anything else. About three inches from the balloon-mouth had better be

strengthened by a layer of calico, which being gashed or scalloped (Fig.

5), pasted and turned over the wire hoop, makes all firm. As to

dimensions of mouth, I consider a circle of eighteen inches’ diameter

quite big enough, and boys will please remember that three times and

about one-seventh of a diameter makes the circumference of a circle.

Having made your balloon, the next thing to do, as it would seem, is to

let it off.

Not exactly. You expect your balloon to lift a weight--fireworks

probably--which I will describe how to manage by-and-by. It will be

necessary, then, to learn by experiment how much weight it will carry;

otherwise, when the time of letting off arrives, you may fail

altogether, and be much disappointed.

The weight-carrying experiment must be performed in a room, to avoid

air-currents, and, as a preliminary, some sort of car must be attached

to the balloon for the purpose of holding the weights. The car may be of

various shapes, but as good a shape as any is this:--

[Illustration: Fig. 7.--CAR.]

It may be made out of cardboard, or, if you like, of wire. You need not

be particular about any sort of elegance. Fire-balloons are designed to

be sent on their travels at night, when any sort of ornament or elegance

lavished on the car would not be seen.

The usual flame for heating the air in a paper balloon is spirits of

wine. Methylated spirit does very well, and is much cheaper than pure

spirits of wine. I do not recommend this source of flame when the

balloon comes to be actually let off, as you will by-and-by see; but for

our present experiment I do recommend it. You must make a note of the

weight of spirits of wine presently to be used, and, if you do not

happen to have scales and weights handy, you may take it for granted

that a sherry wineglass full weighs about an ounce.

Ascertain, too, how much the car weighs. Probably, when the time comes

for letting off the balloon, you will not require the car, so you should

have ascertained its weight, that you may supply a weight equivalent, in

the shape of fireworks, for example.

[Illustration: Fig. 8.--CHAMBER TRIAL OF THE BALLOON.]

Two boys will be wanted for performance of the chamber experiment; one

to stand upon a chair or stool, so as to be able to lift the crown of

the balloon, the other to manage the flame department--to do what

engineers would call the stoking (Fig. 8).

The spirit, you will remember, is not to be burned loosely, but absorbed

by something or other. Sponge is the absorptive medium usually employed,

though some operators use cotton wick. On the present occasion of

chamber experiment I recommend you to employ sponge. The very coarsest

sponge will do as well as the finest and most expensive. Such a piece as

most oilmen sell under the name of ‘slate sponge,’ and generally for a

penny, will do quite well for the chamber experiment.

Let me now give you boys a piece of advice, and do not consider it of

small value. It is of enormous value, being the value of the difference

between success and failure. I do not only mean success or failure in

the experiment you are about to perform, but any experiment. The advice

is this:--Attend well to detail. Before you set about performing any

experiment take care that you have provided, and arranged well to hand,

everything necessary to the performance of the experiment. Do not say to

yourself, this, that, or the other is a trifle, and as a trifle neglect

it. In all experimental work, having once determined in your own mind

the various things and arrangements necessary, nothing amongst them can

be a trifle. Well, to the point. Provide yourself, by loan if your

pocket-money does not run so far, with some handfuls of farthings. This

little coin will be about the most convenient thing you can use for

seeing how much weight your balloon will take up. You are ready. Well,

No. 1, as I will call you, lay hold of the crown of the balloon, then

jump on a stool or chair, lifting the entire balloon up in such way that

the mouth of it may be conveniently disposed for what has to be done by

No. 2.

Previous arrangements having been made, it will be well, to avoid

accidents, for No. 2 to partially inflate the balloon by a fan. Were

this precaution not taken, it might happen that flame driven against the

tissue-paper might set it on fire. Those who have not tried the

experiment little know what power there is in a fan to set up and keep

going a current of air. Sometimes people revive a sluggish fire by

hanging a sheet of paper in front of it, but a far better application of

the paper is to squeeze it into a rough fan and begin fanning. My

attention was first called to this fire-fanning process when, travelling

in Andalusia, I wanted some chocolate in a hurry, at a lonely wayside

_posada_. A damsel, fan in hand, lighted a bit of charcoal with a paper

spill, laid it on the stove grating, put other charcoal round it, the

chocolate-pot over all, and began fanning.

You are now ready to learn how much weight your balloon will carry. You

will have attached the car, of course. You will have laid your bit of

sponge on the tin pan already attached, and you will have remembered to

steady the sponge and keep it from falling out by passing a little iron

binding wire over the surface of it, and attaching the wire to the tin

pan. All this having been done, you are to pour the spirits of wine upon

the sponge and set fire to it. Presently the balloon, becoming charged

with hot air, will fill out and rise. When risen, be prepared with your

money--farthings. Throw in farthing upon farthing until your balloon not

only can carry no more, but comes down. Let it come down, and let the

spirit flame burn quite out. Any attempt at blowing it out would

probably set the balloon in a blaze.

You have gained now the information required; you have learned what

weight, when the serious time of letting off arrives, your balloon will

carry. Count the farthings and make a memorandum of their weight. There

is no particular mystery in the choice of farthings; they are cheap

enough, and they are small enough. Sovereigns and half-sovereigns will

do quite well, and if you are sufficiently ‘warm’ in pocket-money, you

may employ them instead of farthings, over which they present the

advantage of recording the actual weight. A sovereign newly minted

weighs one hundred and twenty-three grains and a small fraction; a

half-sovereign half that weight. Taking one sovereign with another, you

may assume one hundred and twenty-three grains to be the weight of each.

Here, by the way, I may mention that, having weighed hundreds of

sovereigns for the sake of a lazy experiment, I never yet met with two

of exactly the same weight.

[Illustration: Fig. 9.--LETTING OFF THE BALLOON.]

A fire-balloon is a pretty device of itself, but it becomes much better

worth looking at when it is made to take up fireworks, so I will now

give some instructions about these fireworks. I cannot recommend you to

make the fireworks yourselves, but to buy them ready made and arrange

them in suitable devices. You will want a few feet of Bickford’s fuse,

and the same of quickmatch. Both may be obtained of Messrs. Brock, of

Cheapside and the Crystal Palace.

[Illustration: Fig. 10.--BICKFORD’S FUSE.]

[Illustration: Fig. 11.]

Bickford’s fuse is much used by miners for exploding their charges. For

this purpose it is invaluable, a given length burning a given time, so

that the miner knows exactly what his fuse must be in order to afford

him the time necessary for escaping to a safe distance before his charge

goes off. It is invaluable to you boy balloonists in another way. The

prettiest balloon firework effects are those which are not lighted at

the time when you let off your balloon, but which take fire apparently

of themselves after the balloon has gained a considerable elevation.

Bickford’s fuse enables you to accomplish this in a manner you will soon

understand.

Looked at casually, Bickford’s fuse might be taken for a piece of black

cord, something in size like this (Fig. 10). The outside is of woven

material made waterproof. The middle contains an inflammable wick,

burning regularly to time.

If you were to pass through a length of Bickford’s fuse transversely a

thread fixed at its upper end, and having a weight attached to the other

end, and if then you were to light the fuse at one end, you see what

would happen. The fire would creep along until, coming to the thread, it

would burn the latter, and the weight would fall. It is many years since

I had occasion to work with Bickford’s fuse, so I forget its rapidity of

burning. It does not signify; when you have got your fuse you can try an

experiment with any convenient length, timing the rapidity of burning by

a watch.

Quickmatch consists of a paper tube with a rapidly inflammable wick

running through it, the intention being that flame applied to one end of

the match shall flash to the other, and instantaneously. The actual

fireworks I recommend you to get are some blue-lights, some Roman

candles, a few Catherine wheels, crackers, and maroons. The Roman

candles you will only require to pick to pieces for the sake of the

stars they contain, so if you could get the stars you would not want the

candles. Mr. Brock, I think, would supply you with stars of various

colours. He uses small pill-boxes for holding the star material.

I have now to explain to you a few fireworks for your balloon.

[Illustration: Fig. 12.]

1. _Fixed piece of blue-lights._--Having selected a cork of suitable

size, bore its circumference with as many holes not going to the middle

as you design to have blue-lights. Each excavation made will receive the

blank end of a blue-light, just as a candlestick receives the end of a

candle, so that when finished, supposing you to have used four

blue-lights, you will have made something like this (Fig. 12).

[Illustration: Fig. 13.]

On observing the blue-lights which you have purchased, each will be

found to have attached to it at the burning end a screw of soft paper,

usually blue. This I hardly need tell any English boy is touch-paper,

made by saturating soft paper with solution of nitre and drying.

Firework cases are usually finished off with touch-paper, so that they

may ignite immediately. When you send up such an arrangement of

blue-lights as just described, the proposition will be to ignite them

all at once with a flash, and after the lapse of a period of time which

must be left to your own discretion. Quickmatch spread from end to end

of each blue-light, and there secured, either by thread or else a slip

of paper pasted loopwise over it, will accomplish the first, and a

suitable length of Bickford’s fuse the second. All this is obvious, but

a diagram is given (Fig. 13). Hardly necessary is it to tell you that we

want no car when using this device. A wire being passed through the

middle of the cork hooked at one end, for attachment to hooked cross

wires, and bent at the other end so that it shall not slip through the

cork, are also obvious matters.

You will observe that I have represented the quickmatch as actually

running through the Bickford transversely. This is the surest plan in

this and all similar cases, because the walls of the Bickford are so

thick that some time must elapse before they burn quite through.

Transverse perforation and stretching out of the Bickford can easily be

done, the walls of the fuse being very tough. Though my remarks have

been directed to blue-lights only, yet obviously the arrangement applies

to any other variety of tint.

[Illustration: Fig. 14.]

2. _Dropping firework devices._--Some of the prettiest balloon firework

effects are those which do not light until they have separated from the

balloon and fallen through a varying distance, according to your

arrangement. I shall not expect to find that you think it necessary to

inquire how all this may be managed after what I have written about

Bickford fuse and quickmatch. However, some few remarks about a certain

convenience of arrangement may not come amiss. Suppose, then, that you

have launched your balloon carrying several devices--we will assume it

to carry six. You want the first of these devices to part company with

the balloon, and shortly after ignite in falling, all to time. You want

the successive five to part company with the balloon also to time.

Obviously a length of Bickford fuse will accomplish all this, but there

are inconvenient as well as convenient ways of arranging all. A

convenient way is this (Fig. 14).

When I have told you this diagram represents a thing made of wire, and

you are so to use it that a fall shall take place at every corner, you

will see that all can be managed by Bickford fuse.

Amongst the fireworks that are effective when thus falling are small

blue-lights, squibs, crackers, maroons, stars, but more especially

catherine wheels. All explosive fireworks give a shock when

exploded--maroons a great shock. Never, then, use a balloon-attached

firework in such manner as that it shall explode whilst attached to the

balloon, the steadiness of which it would certainly affect--perhaps

cause a tongue of flame to come in contact with the paper and set it on

fire. A wirework arrangement such as our diagram represents is only

intended to carry six successive devices, and for the devices that have

been noted you will most likely find that about half-a-dozen will make

up the total weight your balloon can carry. But there are certain

lighter fireworks, of which considerably more than six may be carried;

for example, stars. If you take a star and enclose it in a tissue-paper

bag, together with a very little--say half a saltspoonful of mealed, or

powdered, gunpowder; then, if you tie the mouth of the bag round a short

length of quickmatch, you see what must happen when the flame of a

Bickford fuse sets the free end of the quickmatch alight. You will rig

up the stars with their bags on wire cross-work as already described,

but you will arrange that the successive ignitions follow a spiral

course, like that of a loosely-coiled watch spring.

I think I have told you as much as can be profitable about the making of

fire-balloons, so a few words now about parachutes. People who ascend in

the cars of large balloons sometimes vary the display by cutting

connection with the balloon itself when at a certain height, and coming

down by aid of a parachute. Parachutes used on these occasions are

somewhat elaborate things, bearing a general resemblance to an umbrella

deprived of its stick and ribs, having a cord attached to the spot where

the terminal of each rib, if present, would have been, these cords all

converging to join at their lower ends with a car.

[Illustration: Fig. 15.]

The parachute I shall describe for your fire-balloons is a more simple

affair, and is made as follows:--Provide yourself with two sheets of

soft whitey-brown paper, some twine, and some paste. Lay one sheet flat

on a table, and then extend diagonally from corner to corner two lengths

of twine which must project at least six inches beyond each corner. It

may be wanted to project even more, but in that case each cord terminal

may be easily lengthened to the desired extent by tying the necessary

additional length of twine to it. Now spread a film of thin paste evenly

by a brush over the sheet of paper and twine, and then close the second

sheet of paper in exact correspondence with the first, as represented in

the diagram.

Be particular, in sticking the two sheets of paper together, to avoid

formation of air bubbles. This can only be done by making the pasting

together successive and not instantaneous--that is to say, do not lay

the second sheet of paper flat down upon the first sheet all at once,

but having begun to effect the attachment at any one edge, follow on

deliberately to the opposite edge, patting the two sheets well together

with a soft pocket-handkerchief.

The way of using such a parachute hardly needs explanation. The

projecting lengths of twine having been brought together, are attached

to a car, and the whole suspended to your balloon, from which you intend

that it shall separate and begin to fall, on your balloon attaining the

desired elevation. This detachment can easily be effected by Bickford’s

fuse. Here, whilst I think of it, never attempt to ignite a Bickford

fuse with anything else than the flame of a port-fire or a blue-light.

The chief beauty of any firework device consists in working to exact

time. A Bickford fuse cannot readily be set on fire with a match-flame.

You may crack many lucifers over the job without succeeding; your

balloon, that ought to be off on its travels, all the time kept waiting.

[Illustration: Fig. 16.]

What will you put in the car? I shall leave this pretty much to your own

taste. Some sort of weight there must be to pull the parachute down. I

have heard of some boys who for ornament peopled the car with little

figures of comical men, cut out of cardboard. I don’t see myself the

sense of it. Fire-balloons are usually let off at night, when the little

caricatures would almost need a spyglass to see them even before the

balloon set out on its explorations. Balloons once off nobody could see

the little men at all. However, do as you like, boys; here are two

notions of such caricature men.

Attention! The point up to which you and I have been working is near. We

are going to let off the balloon. When we were making our chamber trial,

you will remember we used methylated spirit for fuel, absorbing it by a

sponge. You may use the same sort of fuel now if you please, but as for

myself I much prefer the good flare of cotton lamp-wick saturated with

tallow, and sprinkled with either benzoline or turpentine, so that it

may burst into flame without delay at the first touch of other flame.

Not only does tallow burn with a far brighter light than spirits of

wine, but the flame is more lasting. However, boys, I say again--do as

you like. So now farewell to fire-balloons. I will now proceed to tell

you how to make and fill so-called air-balloons, though gas-balloons

would be a name more fitting. They are not of themselves illuminative,

as fire-balloons are, but they will take up any fireworks you please,

according to their weight-carrying capabilities.

III.--ON GASES AND GAS-BALLOONS.

[Illustration]

Having got fire-balloons out of hand, I will now have some words with

you about air-balloons, usually so called, though ‘gas-balloons’ would

be a more appropriate designation. Before describing how to make an

air-balloon, suppose we gossip a little about the science of the thing.

Of gases there are many sorts, as you will become aware when a little

advanced in your chemistry. Atmospheric air is a mixture of two gases,

as probably you know--four measures of nitrogen to one of oxygen,

roughly speaking; though were we describing the composition of

atmospheric air in an exhaustive manner, we should have to chronicle the

presence of numerous other gases besides oxygen and nitrogen, and some

vapours; all, however, in quantities so extremely small that we need

take no account of them here. Some gases are lighter than atmospheric

air, some heavier, but it is evident that those only which are lighter

can be employed for ballooning. The very lightest of all gases is

hydrogen, which therefore is the very best gas for filling balloons. It

is seldom now employed, however, coal-gas being usually substituted, on

account of its being ready to hand, so to say, in every place where

coal-gas illumination is practised.
