One of the best illustrations of this which I know of is in the case of an ex-slave from Virginia whom I met not long ago in a little town in the state of Ohio.

I found that this man had made a contract with his master, two or three years previous to the Emancipation Proclamation, to the effect that the slave was to be permitted to buy himself, by paying so much per year for his body; and while he was paying for himself, he was to be permitted to labour where and for whom he pleased.

Finding that he could secure better wages in Ohio, he went there.

When freedom came, he was still in debt to his master some three hundred dollars.

Notwithstanding that the Emancipation Proclamation freed him from any obligation to his master, this black man walked the greater portion of the distance back to where his old master lived in Virginia, and placed the last dollar, with interest, in his hands.
