Mr. Rankin. Do you recall whether or not you responded to the Exhibit No. 3?
Mr. Johnson. I responded to that together with other letters.
Mr. Rankin. At some later date?
Mr. Johnson. At a later date.
Mr. Rankin. There is a request in Exhibit 3 for additional information or literature. Do you recall whether you sent any additional——
Mr. Johnson. I don't recall exactly, but I would rather imagine not, and for a very simple reason: If I would have, I would have made a notation on here, "Literature sent."
Mr. Rankin. I see. I hand you what has been marked Johnson Exhibit No. 4 and ask you if you recall receiving that.
Mr. Johnson. Yes; I do.
Mr. Rankin. About when compared with the date it bears? Do you remember?
Mr. Johnson. Within just a few days after that.
