[From the Poughkeepsie Daily Eagle, 2 December 1869:]

LYCEUM. -- Mark Twain (Samuel L. Clemens) will lecture before the Lyceum, on Friday evening of this week. This is "Mark's" first appearance in our city. We would advise all who can appreciate sparkling wit and genial humor, to provide themselves with a ticket and wend their way to Collingwood's Opera House, on Friday evening, nothing fearing that they will receive an adequate return from their investment.

MARK TWAIN. -- There was a fine audience at Collingwood Opera House last evening, the occasion being a lecture on the Sandwich Islands by Mark Twain. -- There was much original humor in the lecturer, and too at times he gave splendid illustrations of natural scenery on that far off land. It was a very enjoyable entertainment, and every one in the audience seemed pleased.
