Read it through once

The guide I have spoken of is the only one we have had yet who knew any thing. He was born in South Carolina, of slave parents. They came to Venice while he was an infant. He has grown up here. He is well educated. He reads, writes, and speaks English, Italian, Spanish, and French, with perfect facility; is a worshipper of art and thoroughly conversant with it; knows the history of Venice by heart and never tires of talking of her illustrious career. He dresses better than any of us, I think, and is daintily polite. Negroes are deemed as good as white people, in Venice, and so this man feels no desire to go back to his native land. His judgment is correct.
