The word "mulatto" is found often in the laws of this period, showing that this type was becoming an important factor in the race relations of white and black. As far as is known, there is no way of obtaining even the approximate proportion of white mothers to white fathers, but because of the overwhelming evidence by personal testimony of ex-slaves as to the relations of the masters and overseers of plantations to the slave women, and the corresponding power of the dominant race to prevent, at least in large degree, similar physical marriages between Negroes and the women of their race, we may be said rightly to infer that the proportion of white mothers of colored offspring to white fathers was then, as it has always been, very small. In Maryland, according to Brackett, the child of a white father and a mulatto slave could not give testimony in court against a white person, whereas the child of a white mother and a black man would be disqualified in this regard only during his term of service.[55] "A free mulatto was good evidence," says he, "against a white person."[56] The mulatto of Tennessee had no such social or legal position as either of these cases indicate, although here again personal testimony brings to light notable exceptions of the social behavior of individuals in certain localities, where this type, that is, the colored offspring of white motherhood, was regarded as a separate class, above the ordinary person of color.[57] It is likely that in East Tennessee there was considerable prevalence of such amalgamation of African and Scotch-Irish race stocks, with white motherhood.[58] The reasons were largely economic. Many of the whites who came to live in the lower farm lands down from their first holdings on the rocky slopes and unfertile soil, were driven from these more productive lowlands by the rich white land owners who preferred to have large plantations with great numbers of blacks to raise the crops, rather than to rent or sell to small farmers. For these poorer white neighbors there was no recourse but to take to the mountains and to cultivate there the less desirable lands. The life they had to live was necessarily very rough and hard; their principal diet was corn, and often the rocky soil only yielded them that grudgingly and scantily. They frequently came in contact with the slaves, and the latter were known to steal provisions from their masters' storehouses and bring to these hill-country people appetizing additions to their meager provisions. And the slaves were also known to mingle with them in the quilting, husking, barn-raisings, and other rural festivities, being undoubtedly made welcome. It requires no immoderate imagination to state here the likelihood of much racial intermixure, as we know, from testimony, of more than a few specific cases, and we have, in this rather strange way, the account of social intermingling and the secret gifts of the black men who visited these mountain homes.
