In the management of slave labor the gang system predominated. The great majority of owners, having at the most only one or two families of Negroes, had to work alongside their slaves and set the pace for them. Slavery did not make white labor unrespectable, but merely inefficient. The slave had a deliberateness of motion which no amount of supervision could quicken. If the owner got ahead of the gang they all would shirk behind his back.
