Calloway's Code
(1906)

Then they began to exchange their theories about the cipher.It took Vesey exactly fifteen minutes. He brought to the m. e. a pad with the code-key written on it."I felt the swing of it as soon as I saw it," said Vesey. "Hurrah for old Calloway! He's done the Japs and every paper in town that prints literature instead of news. Take a look at that." ”
