21 August 1923.

Mr. C. F. Jenkins,

1519 Connecticut Ave.,

Washington, D.C.

My dear Jenkins:

Thanks very much for the samples of your

recent work. They look very good. I was

particularly interested in what you said

concerning the Chinese and Japanese methods

of transmitting telegraphy. I had heard

something of this before but never realized

how complicated it would make the process

for them.

As soon as I can get this laboratory

well started I will certainly find time to

look in on you and I hope arrangements may

be made for continuing some cooperative

work with you. We have designated a section

of our organization to work on

methods of secret communication but just

now we are unable to put anyone on that

work.

I hope you will keep me in touch with

your developments and let me know in particular

what progress you are making towards

high speed work. One of the best

arguments that I can make for the Navy

taking up such work will be the matter of

saving time in handling coded messages.

With best regards, I am,

Very truly yours,
