In a letter to the Territorial Enterprise dated Feb. 5, 1868
and  printed on March 1, 1868 Twain writes a very colorful column
about meeting on the street of Broadway in New York a picturesque
character/con artist/journalist/Fenian named Felix O'Byrne --
someone he had known from his days in San Francisco.  According to
Twain, Felix "said he had always remembered me for saying a merciful
word in print for him when he was being sorely hunted by the press of
San Francisco."

Does the earlier Twain writing related to Felix O'Byrne survive
in any collection of his San Francisco writing?
