The 1914 collection by Frank Thomas Bullen, "Songs of Sea Labour", differed from the work of writers such as Masefield in having a more practical, rather than romantic, tone. Bullen, an Englishman, was an experienced shantyman, who sailed during the heyday of shanties to ports in the Southern U.S. and the Caribbean. He took a firm stance that only true work songs should be included in his collection, thus resisting the temptation to let shanties slide into the genres of ballads or other off-duty songs. (Pressure of his publisher forced him to include two sea songs, clearly demarcated, at the end of the book.) And rather than shape the shanties to appear as narrative pieces, he noted that, since most shanties would usually be improvised, it would be disingenuous to present more than one or two sample verses. As for his framing of the genre's origins, Bullen stated his belief that, "great majority of these tunes undoubtably emanated from the negroes of the Antilles and the Southern states, a most tuneful race if ever there was one, men moreover who seemed unable to pick up a ropeyarn without a song ..." And Bullen's musicologist editor, Arnold, claimed, "[The majority of the Chanties are Negroid in origin ..." Bullen's insistence on including only true work songs in the collection meant that he likely omitted songs—generally those for heaving tasks, like capstan work—which had been easily borrowed from the land-based traditions of various nations. The effect of including only the most exclusively work-oriented songs meant that a higher percentage of African-American songs were represented.
