In the old days when American sailing ships still plowed the seas, it was the custom of their sailors to enliven both their work and their leisure time with song. The songs they used were not, generally speaking, those current and popular ashore at the same period, but were traditional compositions of unknown date and authorship, growing as all folk-song does out of the needs and experiences of men. These songs of the sea have in every line of their verses and every bar of their music the distinctive flavor of seafaring. They are of equal interest to students of folk-lore and to those who love the memory of old days spent on blue water; and it is with both in mind that this work has been undertaken.
