Describe how customers examined slaves at the new orleams slave room

From the text:

Next day many customers called to examine Freeman’s “new lot.” The latter gentleman was very loquacious, dwelling at much length upon our several good points and qualities. He would make us hold up our heads, walk briskly back and forth, while customers would feel of our hands and arms and bodies, turn us about, ask us what we could do, make us open our mouths and show our teeth, precisely as a jockey examines a horse which he is about to barter for or purchase. Sometimes a man or woman was taken back to the small house in the yard, stripped, and inspected more minutely. Scars upon a slave’s back were considered evidence of a rebellious or unruly spirit, and hurt his sale.
