The key word is ATCHISON, the cipher disk being used and the setting changed for every letter of the message. The letter X indicates a period where it is evidently not a letter of a word. Deciphering the message with this key and method we have: RELIA BLEIN FORGF TIONF ROMCA SASGR ANDES RECEI LEDHE RETHA TAMOU NTEDD ETACH MSKTL EFTTH ERELA STNIG HTTOE SCORT SHYMP ENTOF ARMSA NDAMM UNITI ONTOB ESMUG GLEDA CRJXS BORDE RNEXT FRIDA YNIGH TATAP OINTT WELVE MIENX FKOSB Beyond this point the message, if we continue the deciphering process, is unintelligible. The sense fails at the first P of the cipher group BSPPK. We have translated B as M with disk A to N and S as I with disk A to A. The last words that make sense are A POINT TWELVE MI; clearly the rest of the last word is LES and this is represented by PPK. Putting P=L then A=A and putting P=E then A=T. In other words, the encipherer forgot to change his disk setting, A to A, after enciphering I into S and enciphered L into P with the same setting, A to A. Continuing the deciphering on this basis, we have: LES EASTO FDOUG LAS.T HISIS INYOU RDIST RICT.

The minor errors underlined above are not difficult to correct except the sixth word in the eighth line. They will be taken up however for analysis of cause of error. Line 1, GF should be MA. Putting the latter into cipher we find the letters of the cipher should have been GO instead of MJ. This is clearly a telegrapher's error, --. --- becoming -- .--- Line 2, L should be V. The corresponding cipher letter should be F instead of P. This is an error of the encipherer in copying. Line 2, SK should be EN. The corresponding cipher letters should be YU instead of KX. Another telegrapher's error, -.-- ..- becoming -.- -..- Line 3, Y should be I. The corresponding cipher letter should be L instead of V. Another error in copying by the encipherer. Line 4, JX should be OS. The corresponding cipher letters should be FK instead of KF; an error on the part of the encipherer in copying. Line 7, V should be Y. A mistake in copying. Line 8, SKZRX. If we take X as a period, then this line might be OVER, the R being correct and SKZ being in question. The corresponding cipher letters are AEO and if we encipher OVE we get ETJ. Here again we have a telegrapher's error, . - .--- becoming .- . ---
