The Buffalo Express, under Mark Twain's management, had become a
sort of repository for humorous efforts, often of an indifferent
order. Some of these things, signed by nom de plumes, were charged
to Mark Twain. When Bret Harte's "Heathen Chinee" devastated the
country, and was so widely parodied, an imitation of it entitled,
"Three Aces," and signed "Carl Byng," was printed in the Express.
Thomas Bailey Aldrich, then editor of Every Saturday, had not met
Mark Twain, and, noticing the verses printed in the exchanges over
his signature, was one of those who accepted them as Mark Twain's
work. He wrote rather an uncomplimentary note in Every Saturday
concerning the poem and its authorship, characterizing it as a
feeble imitation of Bret Harte's "Heathen Chinee." Clemens promptly
protested to Aldrich, then as promptly regretted having done so,
feeling that he was making too much of a small matter. Hurriedly he
sent a second brief note.


To Thomas Bailey Aldrich, editor of "Every Saturday,"
Boston, Massachusetts:

BUFFALO, Jan. 22, 1870.
DEAR SIR,--Please do not publish the note I sent you the other day about
"Hy. Slocum's" plagiarism entitled "Three Aces"--it is not important
enough for such a long paragraph. Webb writes me that he has put in a
paragraph about it, too--and I have requested him to suppress it. If you
would simply state, in a line and a half under "Literary Notes," that you
mistook one "Hy. Slocum" (no, it was one "Carl Byng," I perceive) "Carl
Byng" for Mark Twain, and that it was the former who wrote the plagiarism
