DRAFT 13 November 1944 ~ID:A65535 

There are certain atud1ea nov carried on in the .Militar7 r 

Intelligence Service and the Signal SecuritJ Agency which have many 

pb&aea 1n common. One aucb atudJ' 1nvolvea the determ1n&t1on and 

evaluation or Japanese aourcea ot intelligence, the accuracy of the 

data obtained bf them, and the probable ettect that this intelligence baa upon the1r operations. The Military Intelligence Service 

11 interested in all pbases of the studies 1n this t1eld, but the 

Signal Securit7 Agency is onlJ interested insofar aa "Special 

Intelligence" (crJPtaa&l7ei1 and traft1c analysis) is concerned, (1) 

because or clues 1t 11elde as to the securit7 or insecurity or our

own orntographic aide, aa well aa of the methods and procedures \ 

coDDected therewith, and (2) because or the ettect a knowledge of what 

the Japaneae can do 1D these fields can have upon the methods and prooed\U'ea emplo1ed 1n (a) the interception and solution or Japanese 

military commwucat1one. and (b) in radio countermeasures adopted by 

our own forces. However. the basic aource material tor both organ!zaties undertaking the subject research 1B the aame, and the screening 

process ll\lat be the same. 

In order that unneoeea&rJ dupl1c&t1on ot ettort be avoided, it is 

agreed tbat the members ot eaoh working group in the Military Intelligence Serv1oe and th• Signal Security Agenc7 shall have tree liaison 

with the other, asid tb&t the tiles ot each will be made accessible 

to the other. Such results aa are obtained bJ one organization and are 

ot direct 1.ntereet to the other organization 1n carrfing out their 

respective m1as1ons v111 be exchanged. Where additional tac111t1es 

and personnel are needed to screen and isolate the material for adequate 

coverage, equitable provision w111 be made by mutually agreeable arrangements.
