This the attorney present declined to do, and Mr. D. was obliged to act as his own attorney. The first witness called was Mary, the slave-mother. She testified, in response to questions by the court, that she had been born the slave of Mrs. D.'s father, and had lived in his family until Mrs. D. was married, when she had been given to Mrs. D. as her maid or body-servant; that her daughter Jane, then about five years of age, had been given to Mrs. D. at the same time; that she, Mary, had never been married, but when less than twenty years of age had repeatedly been ordered to the bedchamber of Mrs. D.'s father; that Jane was none other than the daughter of Mrs. D.'s own father, and consequently half-sister to Mrs. D. herself; that she had frequently asked her former master and her present mistress for the privilege to learn to read and write, and, when she had learned herself, that she might teach her daughter Jane, but they had always refused, and given as a reason that the laws of Virginia made it a criminal offence to teach a slave to read or write; that both she and her daughter had been generally well treated by Mr. and Mrs. D. until the Union troops came to Alexandria; that since that time both seemed to have entirely changed in their disposition towards her and her daughter; that nothing they could do seemed to please them; that both she and her daughter had been forbidden to go upon the street at any time or upon any occasion, and that finally they had been forbidden to look out of the windows; that they had tried to obey even this order, but, on hearing music and the tramp of passing soldiers, they had sometimes been drawn to the windows unthinkingly; for this one offence and for no other--for Mrs. D. always reported them to her husband, and seemed to take pleasure in doing so whenever she chanced to catch them at a window--Mr. D. had whipped both her and her daughter several times most terribly; that he always took them to the garret, tied a cord around each wrist, threw the cord over a beam and drew them up until their toes just touched the floor, stripped them to the waist, and then with a rawhide gave them as many lashes as he thought they could stand without fainting; that her own back, and her daughter's as well, were so raw and sore that they could hardly wear their dresses; that Mrs. D. always encouraged these whippings, and that neither she nor her husband ever manifested the least sympathy with their subsequent sufferings; that neither she nor her daughter had ever made an attempt to escape from bondage, nor had either of them ever threatened their master or mistress so to do, notwithstanding all they had suffered. She wept frequently while giving in her testimony, and at times almost the entire audience seemed melted to tears. The Judge was observed to wipe his eyes frequently, and several times his voice was so choked with emotion that he had to hesitate some moments before he could put the next question.
