Letter: [?] to FBI (October 3, 1961)

I would appreciate having a copy of your book or brochure titled THE COMMUNIST PARTY LINE.

Also, can you tell me how to go about getting information as to SCIENTOLOGY, headed by L. Ron Hubbard, 1812 19th Street, N.W., Washington 9, D.C.? They profess to be anti-communist and their teaching the opposite of brainwashing; but as I see it their teaching is definitely brain-washing, and I wonder how they have been able to become worldwide in just eleven years, which they claim.
