As for the "indigenous-leadership cluster," Methedrine addicts have replaced the work-oriented Diggers and driven them...

Since "every letter has a cluster of preferred associations that constitute its most distinguishing characteristic," the next step is to set up a contact chart. This shows how often each letter precedes and is succeeded by each other letter. From this it is clear that N in the ciphertext stands for plaintext e: it is the most frequently used letter, and associates more often with more different characters than does any other letter...
