Blacks were expected to refer to white males in positions of authority as "Boss" or "Cap'n"--a title of respect that replaced "Master" or "Marster" used in slave times. Sometimes, the white children of one's white employer or a prominent white person might be called "Massa," to show special respect. If a white person was well known, a black servant or hired hand or tenant might speak in somewhat intimate terms, addressing the white person as "Mr. John" or "Miss Mary." All black men, on the other hand, were called by their first names or were referred to as "Boy," "Uncle," and "Old Man"--regardless of their age. If the white person did not personally know a black person, the term "nigger" or "nigger-fellow," might be used. In legal cases and the press, blacks were often referred to by the word "Negro" with a first name attached, such as "Negro Sam." At other times, the term "Jack," or some common name, was universally used in addressing black men not known to the white speaker. On the Pullman Sleeping cars on trains, for example, all the black porters answered to the name of "boy" or simply "George" (after the first name of George Pullman, who owned and built the Pullman Sleeping Cars).
