You see there was slave traders in those days. . . . They bought and sold slaves and hired 'em out. Yes'm, rented 'em out. Allotted means somethin' like hired out. But the slave never got no wages. That all went to the master. The man they was allotted to paid the master. I was never sold. My mama was sold only once, but she was hired out many times . . . . We left my papa in Kentucky, 'cause he was allotted to another man. My papa never knew where my mama went, an' my mama never knew where papa went. . . . They never wanted mama to know, 'cause they knowed she would never marry so long she knew where he was. Our master wanted her to marry again and raise more children to be slaves. They never wanted mama to know where papa was, an' she never did. Question: What does Sarah Graves have to tell us about the economic basis of slavery?
