Thirty Years a Slave, and Four Years in the White House) by Elizabeth Keckley

Every room in the White House was darkened, and every one spoke in subdued tones, and moved about with muffled tread. The very atmosphere breathed of the great sorrow which weighed heavily upon each heart. Mrs. Lincoln never left her room, and while the body of her husband was being borne in solemn state from the Atlantic to the broad prairies of the West, she was weeping with her fatherless children in her private chamber. She denied admittance to almost every one, and I was her only companion, except her children, in the days of her great sorrow.
