It must not be assumed, however, that the labor of the Negro has been simply the muscle-straining unintelligent work of the lowest grade. On the contrary he has appeared both as personal servant, skilled laborer and inventor. That the Negroes of colonial times were not all ignorant savages is shown by the advertisements concerning them. Continually runaway slaves are described as speaking very good English; sometimes as speaking not only English but Dutch and French. Some could read and write and play musical instruments. Others were blacksmiths, limeburners, bricklayers and cobblers. Others were noted as having considerable sums of money.[60] In the early days in the South the whole conduct of the house was in the hands of the Negro house servant; as butler, cook, nurse, valet and maid, the Negro conducted family life. Thus by social contact and mingling of blood the Negro house servant became closely identified with the civilization of the South and contributed to it in many ways. For a long time before emancipation the house servant had been pushing steadily upward; in many cases he had learned to read and write despite the law. Sometimes he had entered the skilled trades and was enabled by hiring his time to earn money of his own and in rare cases to buy his own freedom. Sometimes he was freed and sent North and given money and land; but even when he was in the South and in the family and an ambitious menial, he influenced the language and the imagination of his masters; the children were nursed at the breast of black women, and in daily intercourse the master was thrown in the company of Negroes more often than in the company of white people. From this servile work there went a natural development. The private cook became the public cook in boarding houses, and restaurant keeper. The butler became the caterer; the “Black Mammy” became the nurse, and the work of all these in their various lines was of great influence. The cooks and caterers led and developed the art of good-eating throughout the South and particularly in cities like New Orleans and Charleston; and in northern cities like Philadelphia and New York their methods of cooking chicken and terrapin, their invention of ice cream and their general good taste set a standard which has seldom been surpassed in the world. Moreover, it gave economic independence to numbers of Negroes. It enabled them to educate their children and it furnished to the abolition movement a class of educated colored people with some money who were able to help. After emancipation these descendants of the house servant became the leading class of American Negroes. Notwithstanding the social stigma connected with menial service and still lingering there, partially because slaves and freedmen were so closely connected with it, it is without doubt one of the most important of the Negro’s gifts to America.
