“I have often been utterly astonished, since I came to the north, to find persons who could speak of the singing, among slaves, as evidence of their contentment and happiness. It is impossible to conceive of a greater mistake. Slaves sing most when they are most unhappy. The songs of the slave represent the sorrow of his heart; and he is relieved by them, only as an aching heart is relieved by its tears. At least, such is my experience.”
