“ Russell has himself observed that—“The quantity of cotton which can be produced on a [slave-worked] plantation is limited by the number of hands it can turn into the field during the picking or harvesting of the crop. Like some other agricultural operations, this is a simple one, though it does not admit of being done by machinery, as a certain amount of intelligence must direct the hand.”The same is true of a wheat farm, except that much more can be done by machinery, and consequently the extraordinary demand for labour at the wheat harvest is much less than it is on a cotton plantation. ”
