Dear Capt. Arnett: 

292 Davis Street 

Greenfield, }lass. 

June 21 1958 

Thank you for your letter of inquiry about our organization. 

The Library at Arlington Hall has for some years been receiving you<' 

bi-monthly pubb.cation the Cryptogram, and now it is going to Ft. 

George G. HcadC'. 

In it arc found problems of simple substitution variety in Engll.sh, 

and in ~om~ foreign languages: Italian, Spanish, Germ1n, French, and 

when occasional contributions off er them: Russia11, Greek, Hungi.rian, 

etc. WP <'l~o promote the nundi,idcd simple substitution", and some 

rwthcmatical probleM~ in cipher which are our Cryptarithms (but 

ncrely puzzles and not under the category of Cryptography). We offer 

some foreign ciphers: transposition, Bifid, and those of the Vigcnere 

family. Finally, we offer various types of the more complex ciphers 

as e""Cplained in our textbook ''Elementary Cryptanalysis" wtiich was first 

published in 1939, and which cover the field of non-restricted ciphers. 

Outside of the magn~ine, and the textbook, we have no other publications at present, although we hope to produce rewritten Jobs of the 

various cipher-types wln.ch have been brought up-to-date by our members, with short-cuts and the like, in due time. 

We have no Bibliography, preferring to use Galland's when possible, 

and refer inquiri~s to publi~hers that are known to be able to supply 

these book'9. 

Hcmber~hip in the Association is three dollars a year, wlu.ch includes 

six issues of the magazine. 

**if. 

While I run writing there nrc two matters wluch I w1sh you would cornn1ent on, if you can: since our magazine seems to be the only one of 

its lund for the general public, of late there has been a marked increase of foreign subscriptions, which I inherited in January 1958

when I returned as Editor-Publisher. These countries include: Argentina, 

Australia, BelgiUJll, Brazil, Chin~, Cyprus, nenmark, England, \lest Germany, 

Holland, Israel, Japan, Utu.on of South Africa, Portugal., Spain, Venezuela, 

and West Pal.,,1stan. ilJiile, of course, it is good to increase the membership, 

these foreign subscription are more or less of a nuisance, "IJ.nce they are 

often dcman11ng in the search for additional cryptographic literature in tlu.s 

cowitry. We cannot refuse such subscriptions without some basism, of course, 

but there is always that chance that some addresses are cover-up ones for 

''behind the Iron Curtain", and thflt doesn't help matters at all. 

ii- ii- ilRcccntly one of our members reviewed for publication: 

"German H:i.litary Ciphers from February to November, 1918"1 a technical 

paper of the Signal Intelligence Section, War Plans c:.nd Trru.w.ng Division, 

Office of the Cluef Sigm.1 Officer 1 War Department, U. S. Government 

Printing Office, Washington 1935. 

Ue maintriiris (and I have but his word for it) that tlu.s material has been 

decla"Ssificd and that such action was taken by your agency as well as the 

Library of Congress. .As I interpret lu.s letter, he had a micro-film made 

of this paper, turned it over to the University Microfilms, Ann Arbor, 

Michigan, 1~10, in turn are converting the film into a paper-bound book, 

now avaJ.lable to the general public. r.an you verify tlu.s? 

I might add that I have enquired of the latter from another source, so 

you may run across tlu.s additional request. 

Enclo~ed is a sample of our magazine, to give you a general idea of its 

contents. 

Sincerely Yours, 

/s/ William G. Bryan
