Harlow's chanteys are sometimes problematical. You'll have noticed that the first part of his book describes chanteying on board the Akbar in 1876, but later he begins to print songs that he does not specifically connect with that voyage. They are sometimes attributed to other sources, sometimes not. Apparently his voyage on the Akbar provided Harlow's only seafaring experiences.

The unevenness of his treatment of the songs suggests to me that Harlow had not finished his work on "Chanteying on Board American Ships" at the time of his death and left a number of loose ends. As part of his interest in the subject of chanteys, he seems simply to have jotted down some of the songs in the latter part of the book, sometimes from from printed sources, without necessarily endorsing their authenticity, particularly so far back as 1876.

Congratulations on connecting the whistling part of "The Girl in Portland Street" with Child 278. Another new insight.
