The second class comprised the mechanics, carpenters, blacksmiths, masons and the like. These were also a picked lot. They were well trained ofttimes and had a practical monopoly of their trades in many localities. In technical knowledge they naturally soon outstripped their masters and became conscious of their superiority, as the following instance related by President G. T. Winston shows: "I remember one day my father, who was a lawyer, offered some suggestions to one of his slaves, a fairly good carpenter, who was building us a barn. The old Negro heard him with ill-concealed disgust, and replied: 'Look here, master, you'se a first-rate lawyer, no doubt, but you don't know nothin' 'tall 'bout carpentering. You better go back to your law books.'" The training received by these artisans stood them in good stead after the war, when, left to themselves, they were able to hold their ground by virtue of their ability to work alone. The third class was made up of all that were left, and their work was in the fields. The dullest, as well as those not needed elsewhere, were included. Some few became overseers, but the majority worked on the farms. As a rule little work was required of children under 12, and when they began their tasks were about of the adult's. Thence they passed to "half," "three-quarter" and "full" hands. Olmsted said:[7] "Until the Negro is big enough for his labor to be plainly profitable to his master he has no training to application or method, but only to idleness and carelessness. Before children arrive at a working age they hardly come under the notice of their owner.... The only whipping of slaves I have seen in Virginia has been of these wild, lazy children, as they are being broke in to work. They cannot be depended upon a minute out of sight. You will see how difficult it would be if it were attempted to eradicate the indolent, careless, incogitant habits so formed in youth. But it is not systematically attempted, and the influences that continue to act upon a slave in the same direction, cultivating every quality at variance with industry, precision, forethought and providence, are innumerable." In many places the field hands were given set tasks to do each day, and they were then allowed to take their own time and stop when the task was completed. In Georgia and South Carolina the following is cited by Olmsted as tasks for a day:[7]
