Read it through once

“Jack, my boy, you are about to go among a brilliant company of gentlemen and ladies, who are refined and cultivated, and thoroughly accomplished in the manners and customs of good society. Listen to their conversation, study their habits of life, and learn. Be polite and obliging to all, and considerate towards every one's opinions, failings and prejudices. Command the just respect of all your fellow-voyagers, even though you fail to win their friendly regard. And Jack--don't you ever dare, while you live, appear in public on those decks in fair weather, in a costume unbecoming your mother's drawing-room!”
