other tasks where men would need to pull in rhythm. These songs usually have a very punctuated rhythm precisely for this reason, along with a call-and-answer format. Well before the 19th century, sea songs were common on rowing vessels. Such songs were also very rhythmic in order to keep the rowers together. They were notably influenced by songs of African Americans, such as those sung whilst manually loading vessels with cotton in ports of the southern United States. The work contexts in which African-Americans sang songs comparable to shanties included: boat-rowing on rivers of the southeastern U.S. and Caribbean; the work of stokers or "firemen", who cast wood into the furnaces of steamboats plying great American rivers;and stevedoring on the U.S. eastern seaboard, the Gulf Coast, and the Caribbean—including "cotton-screwing": the loading of ships with cotton in ports of the American South. During the first half of the 19th century, some of the songs African Americans sang also began to appear in use for shipboard tasks, i.e. as shanties. Shanty repertoire borrowed from the contemporary popular music enjoyed by sailors, including minstrel music, popular marches, and land-based folk songs, which were adapted to suit musical forms matching the various labor tasks required to operate a sailing ship. Such tasks, which usually required a coordinated group effort in either a pulling or pushing action, included weighing anchor and setting sail. "Poor Paddy Works on the Railway" is a popular Irish and American folk song. Historically, it was often sung as a sea chanty. The song portrays an Irish worker working on a railroad. There are numerous titles of the song including, "Pat Works on the Railway" and "Paddy on the Railway". "Paddy Works on the Erie" is another version of the song. "Paddy on the Railway" is attested as a chanty in the earliest known published work to use the word "chanty", G. E. Clark's Seven Years of a Sailor's Life (1867). Clark recounted experiences fishing on the Grand Banks of Newfoundland, in a vessel out of Provincetown, Mass. c. 1865–66. At one point, the crew is getting up the anchor in a storm, by means of a pump-style windlass. One of the chanties the men sing while performing this task is mentioned by title, "Paddy on the Railway."
