To re::-pond raragraph by paragraph; to exp la in. clarify, 

expsstu la t e, and justify. 

1 o ignore the whole thing as I really don't want to rake 

it all up. 

To say something appropriatly enigmatic and let you and 

your associates stew in it or not as you chose . 

Your own statement that·· . .. my interest has been in the chase and 

not in the kill . · is finally wat deterred me from respondinr at a' l. 

This pro· ed to be no solution. Your letters and paper hav e been 

dtt.ing on n1y desk for tirr.e enough a nd time will e v entually hav e 

\ts way. I ha ·.1e to ansv;er. which rneanl:i I '.Vant t o. 

I don't know how far you ha.-'e progressed with this wnrk since last 

we were in i ouch, but here are a few itet1H· that might be of sorr e 

inte1 ei:it to you or to others . 

l truly admire: (am even amazed by) your worl-. even in t hose areas 

with which l cannot.or just C:on 't,agree . 

Fqr reason!:. l can r .. ot honestly cieHne l am not yet prepared to show 

you or anyone else the biueprint~ of my fa ther's "device . 

The infamous cigar box wa~ "lost s t olen, or s trayed" before my

The model my father, mot her, and I worked on was dest royed by 

me sho1tly after my fa t her's ciea th. 

Rn t ber blindfold chess and a 11 tho:,c other mcnt.a l gymnastics ? 

My fatfh:r hardly ever used · 1-.encil and paper' except for making

Dad fore! aw the ar.!vent of a con.puter technology a11d predicted that 

one day the use of hi.s ~y ::-tern would be as ' s i.-riple as u~ing a

(Back to the cigar box) ... It was not at all a !et:£P.r cont ri.v'lnce in 

terms of its capadty to perforn the full function(s) of the envisioned

to call it, the ''resolution . 

Forget about t..ucHd, Heron, Joyce, and all tbbse others. Use your 

ow~ head you obviously ha·,c a damn good one. 

Final11.,-nand as far as I will go right now there is the matter o! 

l !!:ACE and ·1 f,,;NEFJ1 S. I have~ been at some espt:!nditure d time 

to cherk ~v::..ila.ble carbon copies ._,f tlle original manuscript agains~ 

tlic ?a ltey proofr.;. I can assure you 1 hat to the b€'si. of my know ledge 

you should use the correct plain text spelling PciAi'OE and BENE.i-~ TS 

for :;..11 applications. I am astounded that these typos got past our 

attention . I remember help~ng my mother and father check the 

galley proofs letter by damnable letter. w· e quite naturally concentrated 

on thC" cipher t.ext to as~ure its<. bsolut accuracy. Apparently the p~ain 

te:~ m.d not receive the sanie ' devoted.' attention. 

I can concieve of no way i.hat thetH~ pril1\-ing errors can r~·lect errors 

in the enc.ipherment. i3oth my father1s wo!"king notes and the <.tvai.Ic.ble 

manuscript copie~ u) :>t"lntiate this judgement. 

I have neither sought nor found any explanation whatsoever f.or 

\T_t.,GA 'l'ENTUR . I don't know whv!-e _ .:a.lico Belly my father 

w·as enjoying at that time . Sometime I 1 ll look into it.

tod me that. you would like to SE"<' it again some time. Please eYcu.Ee 

1uy tem pora 1 irreverance. 

One last note before closing. I must admit to that which you already 

suspect. The copies of C ryptogran and Cryptologia which you so kindly 

sent·sC'rved only to turn me off . 1 truly an-. not sure that I have anythinJ 

to contriuute to the meetings .. . and l don td:hi.nk 1 dig the lingo .
