In February of 1957, L. Ron Hubbard traveled to Puerto Rico where he continued researching and writing.

In April, he flew to London, England once more to deliver a series of lectures on auditing techniques and then traveled to back to Washington, D.C.

While still concentrating on further organizational and administrative developments and delivering over 145 public lectures, L. Ron Hubbard also wrote Scientology Clear Procedure, Issue I and Control and the Mechanics of S.C.S. to better speed an individual’s spiritual progress in auditing to Clear.
