Maybe someone else can identify the three other tunes printed by Peck.

I believe that No. 3 is the tune used by one or more of Carpenter's singers for "Victorio" or "Very Well Done, Jim Crow!"

The final bars of No. 1 seem to make up a chorus that scans like that of "Stormy Old Weather, Windy Old Weather."

No. 2 reminds me a little of the Scots song "Drumdelgie" and the Irish tune "O'Keefe's Slide."

I wouldn't discount their possible use in shanties.
