From the text:
I was seldom whipped by my old master, and suffered little from any thing else than hunger and cold. I suffered much from hunger, but much more from cold. In hottest summer and coldest winter, I was kept almost naked—no shoes, no stockings, no jacket, no trousers, nothing on but a coarse tow linen shirt, reaching only to my knees. I had no bed. I must have perished with cold, but that, the coldest nights, I used to steal a bag which was used for carrying corn to the mill. I would crawl into this bag, and there sleep on the cold, damp, clay floor, with my head in and feet out. My feet have been so cracked with the frost, that the pen with which I am writing might be laid in the gashes.
We were not regularly allowanced. Our food was coarse corn meal boiled. This was called mush. It was put into a large wooden tray or trough, and set down upon the ground. The children were then called, like so many pigs, and like so many pigs they would come and devour the mush; some with oyster-shells, others with pieces of shingle, some with naked hands, and none with spoons. He that ate fastest got most; he that was strongest secured the best place; and few left the trough satisfied.
I was probably between seven and eight years old when I left Colonel Lloyd's plantation. I left it with joy.
