〃Now; in English; the letter which most frequently occurs is e。

Afterwards; the succession runs thus: a o i d h n r s t u y c f g l

m w b k p q x z。  E predominates so remarkably; that an individual

sentence of any length is rarely seen; in which it is not the

prevailing character。



〃Here; then; we have; in the very beginning; the groundwork for

something more than a mere guess。  The general use which may be

made of the table is obviousbut; in this particular cipher; we

shall only very partially require its aid。  As our predominant

character is 8; we will commence by assuming it as the e of the

natural alphabet。  To verify the supposition; let us observe if the

8 be seen often in couplesfor e is doubled with great frequency

in Englishin such words; for example; as 'meet;' 'fleet;'

'speed;' 'seen;' 'been;' 'agree;' etc。  In the present instance we

see it doubled no less than five times; although the cryptograph is

brief。



〃Let us assume 8; then; as e。  Now; of all WORDS in the language;

'the' is most usual; let us see; therefore; whether there are not

repetitions of any three characters; in the same order of

collocation; the last of them being 8。  If we discover repetitions

of such letters; so arranged; they will most probably represent the

word 'the。'  Upon inspection; we find no less than seven such

arrangements; the characters being ;48。  We may; therefore; assume

that ; represents t; 4 represents h; and 8 represents ethe last

being now well confirmed。  Thus a great step has been taken。



〃But; having established a single word; we are enabled to establish

a vastly important point; that is to say; several commencements and

terminations of other words。  Let us refer; for example; to the

last instance but one; in which the combination ;48 occursnot far

from the end of the cipher。  We know that the ; immediately ensuing

is the commencement of a word; and; of the six characters

succeeding this 'the;' we are cognizant of no less than five。  Let

us set these characters down; thus; by the letters we know them to

represent; leaving a space for the unknown





t eeth。





〃Here we are enabled; at once; to discard the 'th;' as forming no

portion of the word commencing with the first t; since; by

experiment of the entire alphabet for a letter adapted to the

vacancy; we perceive that no word can be formed of which this th

can be a part。  We are thus narrowed into





t ee;





and; going through the alphabet; if necessary; as before; we arrive

at the word 'tree;' as the sole possible reading。  We thus gain

another letter; r; represented by (; with the words 'the tree' in

juxtaposition。



〃Looking beyond these words; for a short distance; we again see the

combination ;48; and employ it by way of TERMINATION to what

immediately precedes。  We have thus this arrangement:





the tree ;4(4+?34 the;





or; substituting the natural letters; where known; it reads thus:





the tree thr+?3h the。





〃Now; if; in place of the unknown characters; we leave blank

spaces; or substitute dots; we read thus:





the tree thr。。。h the;





when the word 'through' makes itself evident at once。  But this

discovery gives us three new letters; o; u; and g; represented by

+; ?; and 3。



〃Looking now; narrowly; through the cipher for combinations of

known characters; we find; not very far from the beginning; this

arrangement;





83(88; or egree;





which plainly; is the conclusion of the word 'degree;' and gives us

another letter; d; represented by !。



〃Four letters beyond the word 'degree;' we perceive the combination





;46(;88。





〃Translating the known characters; and representing the unknown by

dots; as before; we read thus:





th。rtee;





an arrangement immediately suggestive of the word thirteen;' and

again furnishing us with two new characters; i and n; represented

by 6 and *。



〃Referring; now; to the beginning of the cryptograph; we find the

combination;





53++!。





〃Translating as before; we obtain





。good;





which assures us that the first letter is A; and that the first two

words are 'A good。'



〃It is now time that we arrange our key; as far as discovered; in a

tabular form; to avoid confusion。  It will stand thus:





5 represents a

!     〃      d

8     〃      e

3     〃      g

4     〃      h

6     〃      i

*     〃      n

+     〃      o

(     〃      r

;     〃      t

?     〃      u





〃We have; therefore; no less than eleven of the most important

letters represented; and it will be unnecessary to proceed with the

details of the solution。  I have said enough to convince you that

ciphers of this nature are readily soluble; and to give you some

insight into the rationale of their development。  But be assured

that the specimen before us appertains to the very simplest species

of cryptograph。  It now only remains to give you the full

translation of the characters upon the parchment; as unriddled。

Here it is:





〃'A good glass in the bishop's hostel in the devil's seat forty…one

degrees and thirteen minutes northeast and by north main branch

seventh limb east side shoot from the left eye of the death's head

a bee…line from the tree through the shot fifty feet out。'〃





〃But;〃 said I; 〃the enigma seems still in as bad a condition as

ever。  How is it possible to extort a meaning from all this jargon

about 'devil's seats;' 'death's heads;' and 'bishop's hostels'?〃



〃I confess;〃 replied Legrand; 〃that the matter still wears a

serious aspect; when regarded with a casual glance。  My first

endeavor was to divide the sentence into the natural division

intended by the cryptographist。〃



〃You mean; to punctuate it?〃



〃Something of that kind。〃



〃But how was it possible to effect this?〃



〃I reflected that it had been a POINT with the writer to run his

words together without division; so as to increase the difficulty

of solution。  Now; a not overacute man; in pursuing such an object;

would be nearly certain to overdo the matter。  When; in the course

of his composition; he arrived at a break in his subject which

would naturally require a pause; or a point; he would be

exceedingly apt to run his characters; at this place; more than

usually close together。  If you will observe the MS。; in the

present instance; you will easily detect five such cases of unusual

crowding。  Acting upon this hint I made the division thus:





〃'A good glass in the bishop's hostel in the devil's seatforty…
