worry about this talk. On Friday I talked with
about what he should say on NSA. Changes in organization of
NSA have been so frequent that he is going to put together some
charts of his own and submit them on 18 August. I had made an
outline of the main topics of his speech since he seemed some-

4. NS= #6 is the basic charter of ELINT. I have been
unsuccessful in getting a copy for the course. Prolonged
25X1 negotiations led from' I its special guardian in
OCI, to the Assistant Director himself, and finally to his
25X1 depatTpl lsaid that the document was
so delicately worded that it could not be given to students.
He did, however, offer to send over a man to brief the class on
it. I in turn suggested that do the job.

in certain particulars, they do not affect the relationship of
ELINT and COMINT.

applicable to ELINT and that is dated 1956. He is sending over
15 copies. I found out from of OC that Commo wrote
up a special ELINT operation that is now with OSI. I have a
series of leads into OBI toward finding it. of Staff
D promised that he would see what he hdd in his files. Mr.
25X1 I _ _ Isaid that he would be glad to take ELINT materials
turned over to him and put them into the regular format of
operational aids. He also said that he thought his staff could
get the job done by 6 October.
7. The glossary is getting slow accretions. I am trying to
farm out the new words to various sections for definitions. An
immediate difficulty is that there are no authoritative sources
for some of the words.
I am trying to run down an Air Force map of pinpointed

copies in OCR.
9. The ELINT Review, put out by NTPC, contains in an
appendix a list of of all radars thus far discovered,
together with parameters and brief descriptions. I have asked
through OSI for 15 copies of the appendix.
Administration:

from an orientation tour of Cape Canaveral. He described the OC

called to them. He said the final equipment was now being
installed and should be fully ready by 6 October. He also
made an admirable suggestions that students take signals on
the black box to get some idea of its limitations on telemetry
signals.
25X1 11. said that he thought the plane could be
chartered without difficulty; it would cost about a $1000 dollars
for the round, trip if the plane left one night and came back to
its Washington port on the third night to be ready for operations
25X1 the next day. I I is away but I will brace him for funds
when he returns.
Deus ex Machina:
25X1 12. On Friday,) Irepoited that
25X1 Chief of had said positively that all students shoed
have CONINT clearance. I proposed that for this first course we
recruit our students one by one, cheek them out in personal inter-
views, and make no formal announcement of the course by bulletin.
I talked this matter over with) in the afternoon and
he seemed to think the method was feasible. I ion his
staff started immediately to make calls among the divisions. We
can get the students, I feel confident, but we cannot get them all
at the case officer level. I have no objection to pulling a few
from the FI staff, provided they have, at that level, some connection
with RLTNT.
Summary:
