What does Douglass do when he is free at first?

Really Douglas was pretty scared and lonely. He was starving and homeless until he met Mr. Ruggles,

Thank Heaven, I remained but a short time in this distressed situation. I was relieved from it by the humane hand of Mr. DAVID RUGGLES, whose vigilance, kindness, and perseverance, I shall never forget. I am glad of an opportunity to express, as far as words can, the love and gratitude I bear him.
