  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…
  one degrees and thirteen minutesnortheast and by northmain
  branch seventh limb east sideshoot from the left eye of the
  death's heada 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 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 reinstituted 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 rocksone 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 leveling 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 down; until my
  attention was arrested by a circular rift or opening in the foliage
  of a large tree that overtopped its fellows in the distance。  In
  the center of this rift I perceived a white spot; but could not; at
  first; distinguish what it was。  Adjusting the focus of the
  telescope; I again looked; and now made it out to be a human skull。
  〃Upon this discovery I was so sanguine as to consider the enigma
  solved; for the phrase 'main branch; seventh limb; east side;'
  could refer only to the position of the skull upon the tree; while
  'shoot from the left eye of the death's head' admitted; also; of
  but one interpretation; in regard to a search for buried treasure。
  I perceived that the design was to drop a bullet from the left eye
  of the skull; and that a bee…line; or; in other words; a straight
  line; drawn from the nearest point of the trunk 'through the shot'
  (or the spot where the bullet fell); and thence extended to a
  distance of fifty feet; would indicate a definite pointand
  beneath this point I thought it at least POSSIBLE that a deposit of
  value lay concealed。〃
  〃All this;〃 I said; 〃is exceedingly clear; and; although ingenious;
  still simple and explicit。  When you left the Bishop's Hotel; what
  then?〃
  〃Why; having carefully taken the bearings of the tree; I turned
  homeward。  The instant that I left 'the devil's seat;' however; the
  circular rift vanished; nor could I get a glimpse of it afterwards;
  turn as I would。  What seems to me the chief ingenuity in this
  whole business; is the fact (for repeated experiment has convinced
  me it IS a fact) that the circular opening in question is
