Lincoln's Memory and Rhetoric

[David Lockmiller]

In Lincoln In The Telegraph Office David Homer Bates wrote:

"He likened this mysterious, instantaneous and twofold operation to the telegraph, although as regards the dual process it should be remembered that the invention of duplex telegraphy was not brought into use until more than ten years after this interesting discourse of Lincoln in the presence of his solitary auditor."

This statement would tend to cast some doubt on the rest of the discourse.
