Marsh had his own form of shorthand, which I believe he shared with Clemens. By the early 1880s Marsh had polished it enough to write a book on it. As a result Marsh's system was widely used by 1900. Rice's background was as a clerk in a Buffalo, N.Y. newspaper, not as a reporter there. I doubt he knew shorthand, but as a reporter who didn.t know shorthand I can assure you from my reporter jobs that we quickly find our own ways of taking good notes. Rice came West hoping to be Gov. Nye's private secretary, but Nye had brought along, for that post, his next door neighbor in New York City, Sam Gallagher, who didn't stay West all that long after getting lost for a few days in the dry west-central Nevada hills. (Orion Clemens was Secretary of the Territory, not the governor's secretary.) One report said Gallagher had been with the New York Press, but he did not take a reporting job while here in Nevada Territory. There is no clear answer to the question of which house Marsh spent the most time covering.

When Miller was compiling the First Constitutional Convention articles for the book you mention, he compiled the thick pile of notes left by the secretary in a single file. That stack of paper is in the Nevada State Archives. I have the only known Xerox copy of those pages, courtesy of a now-deceased friend who was involved.

 The most substantial source of information is
 *Letters from Nevada
 Territory 1861-1862* (by Marsh) and
 *Reports of the 1863 Constitutional
 Convention* (by Clemens, Marsh and
 Bowman) (Reno: Legislative Council
 Bureau, 1972).
