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(?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噰?

    〃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

    〃We have; therefore; no less than ten 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 hotels?' 〃

    〃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 over…acute 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 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。' 〃

    〃Even this division;〃 said I; 〃leaves me still in the dark。〃

    〃It left me also in the dark;〃 replied Legrand; 〃for a few days; 
during which I made diligent inquiry; in the neighborhood of 
Sullivan's Island; for any building which went by the name of the 
'Bishop's Hotel;' for; of course; I dropped the obsolete word 
'hostel。' Gaining no information on the subject; I was on the point 
of extending my sphere of search; and proceeding in a more systematic 
manner; when; one morning; it entered into my head; quite suddenly; 
that this 'Bishop's Hostel' might have some reference to an old 
family; of the name of Bessop; which; time out of mind; had held 
possession of an ancient manor…house; about four miles to the 
northward of the Island。 I accordingly went over to the plantation; 
and re…instituted my inquiries among the older negroes of the place。 
At length one of the most aged of the women said that she had heard 
of such a place as Bessop's Castle; and thought that she could guide 
me to it; but that it was not a castle nor a tavern; but a high rock。

    〃I offered to pay her well for her trouble; and; after some 
demur; she consented to accompany me to the spot。 We found it without 
much difficulty; when; dismissing her; I proceeded to examine the 
place。 The 'castle' consisted of an irregular assemblage of cliffs 
and rocks … one of the latter being quite remarkable for its height 
as well as for its insulated and artificial appearance I clambered to 
its apex; and then felt much at a loss as to what should be next 
done。

    〃While I was busied in reflection; my eyes fell upon a narrow 
ledge in the eastern face of the rock; perhaps a yard below the 
summit upon which I stood。 This ledge projected about eighteen 
inches; and was not more than a foot wide; while a niche in the cliff 
just above it; gave it a rude resemblance to one of the hollow…backed 
chairs used by our ancestors。 I made no doubt that here was the 
'devil's seat' alluded to in the MS。; and now I seemed to grasp the 
full secret of the riddle。

    〃The 'good glass;' I knew; could have reference to nothing but a 
telescope; for the word 'glass' is rarely employed in any other sense 
by seamen。 Now here; I at once saw; was a telescope to be used; and a 
definite point of view; admitting no variation; from which to use it。 
Nor did I hesitate to believe that the phrases; 〃forty…one degrees 
and thirteen minutes;' and 'northeast and by north;' were intended as 
directions for the levelling of the glass。 Greatly excited by these 
discoveries; I hurried home; procured a telescope; and returned to 
the rock。

    〃I let myself down to the ledge; and found that it was impossible 
to retain a seat upon it except in one particular position。 This fact 
confirmed my preconceived idea。 I proceeded to use the glass。 Of 
course; the 'forty…one degrees and thirteen minutes' could allude to 
nothing but elevation above the visible horizon; since the horizontal 
direction was clearly indicated by the words; 'northeast and by 
north。' This latter direction I at once established by means of a 
pocket…compass; then; pointing the glass as nearly at an angle of 
forty…one degrees of elevation as I could do it by guess; I moved it 
cautiously up or
