liEPlORAN'ml! FOR OP-20-S: 

As you will remember. Camrrander Wenger transmitted several weeks 

ago a memorandUM stating that there was sone question as to the technical quality of the pS.l"aphrasing done to State Department dispatches 

which are include~ in the O.N.I. periodical inf'ormation bulletin. 

I was unable to get the exact messa~es. but I ascertained that they 

were available to Colonel Cook. Accordingly, I secured a copy of the 

o.N.I. Bulletin and sent it to Colonel Cook with the request that he ~ 

opmpare the paraphrases with the originals and read.er an opinion. 

Be has returned the Bulletin with the oral statement that the 

par_a.phrases ha.ve been satisfactorily made. 

A sa:r.iple of the o.N.I. Bulletiu is attached. 

Respectfully, 

/s/ R. L. DENSFORD

MEl{ORA:t."'DUJ! FOR Op-20-S: 

April 6, 1943 

Subject: Brief of Telegrar.i.s of Departir~nt of State. 

1. • Colonel UoCormaok of G-2 recently called to my attention a daily publication prepared by ONI (Op-16-C) entitled, nBrjef 

of Telegrams of the Department of Staten. He said t~t the Speical 

Intelligence. Section of G-2 published a similar resume but in much 

briefer form' and thoroughly paraphrased. His group in G-2 are much 

concerned over the fact that me.D.7 •or the telegrams quoted are very 

poorly paraphrased. and e;ive the British, who are on. the distribution 

list, an excellent means of getting into State Department communications. lie ~aid that recen.,tly Field Marshal Dill remarked to General. 

Strong that British crypta.~alysts could read the traffic of arry nation, 

including the u. s. Colonel l!cCormack said it was no wonder they could 

when we provirled them. with such things as this O?lI buttetin; he could 

not imagine the British Foreign Office supplying us with a loose paraphrase of all of their telegrams • . 2. I have not seen the publication in question, but I am 

passing this ini'orr:iation on to you because it bears on Security, and 

possibly the 111&tter is worth looking into.
