How does Uncle Tom make Eva’s acquaintance?

Aboard the ship are a rich gentleman from New Orleans, Augustine St. Clare, and his five-year-old daughter Evangeline. "Little Eva" is a beautiful child who always dresses in white. Her actions are equally angelic as her appearance, as she secretly brings Tom and the slaves candy, oranges, and other snacks. Tom carves trinkets for this little girl, who truly seems divine to him.

Eva falls overboard one day when the boat makes an abrupt stop, and Tom jumps in after her and saves her life. In gratitude, and with Eva's urging, Augustine St. Clare purchases Tom.
