Dear :Bill: 

April 6, 1943

I checked with Miss Weber in regard to 

ADDRESS ALL COMMUNICATIONS 

CHIBF SIGNAL OFl"IC•R 

your letter of the 2nd. She is positive that she 

destroyed no records e%cepting the Reading File copies 

of corres~ondence over a month old, and m,y personal 

correspondence which did not pertain to the office in 

any' wa:y. 

Therefore, the "record'' memorandum, ii' it 

is to be found at all, should be in one of the two 

places I mentioned in my letter of March 25th -

1.- "Foreign Bepresentatives 11 file 

2.- "Black Book11 (Possibly in an Agenda) 

You might ask Col. Cook if there is &Jl1' 

mention made of this in the minutes of the "Xai'i'ee 

Xlatches" held by the section heads. 

Begards. 

Sincerely yours, 

Colonel,

Dear Franks 

Apr11 2 1 1943 

I want to th&llk you ~er7 muoh tor 70~ letter 

ot March 25, in reaponsa to my telephonic appeal to 

you tor 1ntormation. 

I app~eoiate ver7 a1noerel1 the torthrightness or 7our response, vhioh vill be ot considerable 

assistance. I regret to add, however, that diligent sereh through all the tilea that vere 1n your ott1oe, 

or in prox1m1t7 the~eto. baa thus tar tailed to disclose the "record" memorandum to which 7ou re:t"er 1n 

7our second paragraph. Mias Weber ma.7 be able to 

answer the question as to whethe~ al11' records ot this 

nature were destroyed prior to her departlll'e in a gen- eral cleaning-up process. I tnight suggest also that 

it is barel7 possible that you made some notes 1n 

7our personal memorandum book1 which 7ou uauall7 ca~ried on 7our person. Ar17 additional 1ntormat1on 

which might ahed light on tho episode will be grate- tull7 received. I am about to engage in aome verbal 

tiet1cutrs and need all the a:r:imunition I can gather together. 

You vill probabl7 recollect that the nev instructions arose as a result or the realization on 

the part ot certain persona 1n G-2 that our relations 

with the British h&d deteriorated to a great extent 

and that corrective moaaUl'ea had to be taken. 

I do recall that you not onl7 oommun1oated to 

me orally and alone the nev instructions but also 7ou 

called a apeoial •eeting ot section heads the next daJ
