Mr. LEE. Well, this is a recommendation which was made, an organizational recommendation which had been made a long time before I myself had gone into a position with the organization. Because of the nature of the organization, people would come and go. They would support it and then drop out, and sometimes they would move, and if somebody--naturally most of the thing was just a small, little local activity. People didn't maintain business offices for such an organization, and if a person would move or drop out of the organization and the activities, the communications between the national office and the local area would get all tangled up because we didn't know where the mail would be returned, where we would write, whereas if there was a post office box, if one person in the organization dropped out who was receiving mail, then the mail would still be delivered to a post office box, where the other officials of the chapter, if it still existed, would still have access to the mail and be able to reply to communications from the national organization concerning the activities of the organization. The purpose of the post office box was purely to facilitate communications between areas and maintain them on a permanent basis. Mr. RANKIN. I hand you Exhibit 3-A and see if you recall seeing the original of which that appears to be a photocopy. It is dated May 22, 1963. Mr. LEE.

Do you recall having seen that before? Mr. LEE. Yes. This was another one of the communications which were sent to me. Obviously, not through recollection of having seen the letters but piecing these things together, I conclude that this was one of the letters which were sent after I had entered into direct communications with this person, because he no longer addresses it "Dear Sirs." Evidently he has received communications from us, so he addresses us by name. I would say that evidently that was a communication sent to me which I received. Mr. RANKIN. You will note it has four pages as a part of the letter and has a membership blank for----
