Frederick Douglass (1818-1895) was born into slavery in Maryland. As an adult, he escaped into freedom. He became a writer, orator and advocate for the abolition of slavery. In 1845, 16 years before the start of the Civil War, Douglass published his autobiography, Narrative of the Life of Frederick Douglass, An American Slave.
From Chapter VIII
In a very short time after I went to live at Baltimore, my old master’s youngest son Richard died; and in about three years and six months after his death, my old master, Captain Anthony, died, leaving only his son, Andrew, and daughter, Lucretia, to share his estate. He died while on a visit to see his daughter at Hillsborough. Cut off thus unexpectedly, he left no will as to the disposal of his property. It was therefore necessary to have a valuation of the property, that it might be equally divided between Mrs. Lucretia and Master Andrew. I was immediately sent for, to be valued with the other property. Here again my feelings rose up in detestation of slavery. I had now a new conception of my degraded condition. Prior to this, I had become, if not insensible to my lot, at least partly so. I left Baltimore with a young heart overborne with sadness, and a soul full of apprehension. I took passage with Captain Rowe, in the schooner Wild Cat, and, after a sail of about twenty-four hours, I found myself near the place of my birth. I had now been absent from it almost, if not quite, five years. I, however, remembered the place very well. I was only about five years old when I left it, to go and live with my old master on Colonel Lloyd’s plantation; so that I was now between ten and eleven years old.
We were all ranked together at the valuation. Men and women, old and young, married and single, were ranked with horses, sheep, and swine. There were horses and men, cattle and women, pigs and children, all holding the same rank in the scale of being, and were all subjected to the same narrow examination. Silvery-headed age and sprightly youth, maids and matrons, had to undergo the same indelicate inspection. At this moment, I saw more clearly than ever the brutalizing effects of slavery upon both slave and slaveholder.
Which is true according to the text?
1.It was clear who would inherit the property after Captain Anthony's death.
2.The valuation is a thorough examination of the property.
3.Slavery had reciprocal effect on the parties involved.
4.Frederick has always held a very strong opinion about slavery.
5.Frederick was scared of his future.
