I saw Carnival Boat (1932). Just over an hour long, story set in a lumber camp where the son of the foreman falls in love with an entertainer on the carnival boat (no sign of any carnival though).
Scenes on a runaway lumber train and logs jammed in a dam provide some excitement. Some of the acting was poor.
The entertainer was played by Ginger Rogers in a very early film in her career and made a year before she and Fred Astaire came to prominence in Flying down to Rio.
