Professor Hart, of Harvard University, in his recent work, Slavery and Abolition, says:
"The fact that some thousands of negroes every year left the Border States for the South seemed to show that there was profit in keeping them alive; but recent investigation seems to establish that the greater number of these negroes were taken in a body by the men who owned them to settle in other states." (Slavery and Abolition, Hart, p. 124).
