Noted chess historian John Hilbert, the author of tremendous works on Shipley, Napier and Whitaker to mention but a few, has uncovered an interesting addition to the first volume of the MI Chess History (see below #6).

This appears to be a game taken from the tournament you mention in "The First Hundred Years" at p.33, where you write "The first mention of a local championship is in The Argonaut column The Chess Player, a tournament at the Mechanics' Institute in 1885 won by J. Waldstein, with N.J. Manson 2nd and Fritz Peipers 3rd."
