COMBINATIONS OF KEYS.
The work was performed at first with
short dispatches only. When the longer
ones were undertaken, they were found 10
be all formed upon a combination Of two or
more of the ten sequences already discov-
cred, or upon the repetition of some one OF
them. Messages Of sixty world, for instance,
we're Instantly d%eciphered by applying a 80
word key twice. A message of rs words was
read by applying first a sequence Of Is and
then using a 3O.word key twice. A telegram
Of 1856 words yielded to the following rather
complicated formula: 15x25x25x20x25x25.
| The precise combination that had been used
was Of course not always apparent TO the re-
%ceiver, but a few trials with the bunch oil
keys would generally suffice. Occasionally
the message itself gave the necessary direc-
tions for its Interpretation. A telegram
apparently from MI. NJ .rble) addressed to
| Colonel Pel.on, begins: "To Tilden. Re.
~pea,ing Is cipher only" and several repeti.
lions Of a % word sequence do interpret it
Another from the zane peraon-a message
of 200 Words begins: 'Use four times five
cipher" and Yields to a 20 word kew. Occa.

dispatches tina. a word was dropped, ei.he,
by a blunder of the telegraph operator. o,
by preconcerted arrangement. In that cas-.
Of course the subsequent words were thrown
out Of place: but ty shifting all the mum

this dropping Of a word occurs, the dispatch
falls short. BY one Of the number Of word,

word, bu, by following the key it rs cary L

These irregularities, therefore, far from in
validating the principle Of the key, are OF
the contrary a strong confirmation Of it
