Other lowland plantations on a scale similar to that of Sabine Fields showed much better earnings.  One of these, in Liberty County, Georgia, belonged to the heirs of Dr. Adam Alexander of Savannah.  It was devoted to sea-island cotton in the ’thirties, but rice was added in the next decade.  While the output fluctuated, of course, the earnings always exceeded the expenses and sometimes yielded as much as a hundred dollars per hand for distribution among the owners.[36]

The system of rice production was such that plantations with less than a hundred acres available for the staple could hardly survive in the competition.  If one of these adjoined another estate it was likely to be merged therewith; but if it lay in isolation the course of years would probably bring its abandonment.  The absence of the proprietors every summer in avoidance of malaria, and the consequent expense of overseer’s wages, hampered operations on a small scale, as did also the maintenance of special functionaries among the slaves, such as drivers, boatswains, trunk minders, bird minders, millers and coopers.  In 1860 Louis Manigault listed the forty-one rice plantations on the Savannah River and scheduled their acreage in the crop.  Only one of them had as little as one hundred acres in rice, and it seems to have been an appendage of a larger one across the river.  On the other hand, two of them had crops of eleven hundred, and two more of twelve hundred acres each.  The average was about 425 acres per plantation, expected to yield about 1200 pounds of rice per acre each year.[37] A census tabulation in 1850, ignoring any smaller units, numbered the plantations which produced annually upwards of 20,000 pounds of rice at 446 in South Carolina, 80 in Georgia, and 25 in North Carolina.[38]

Indigo and sea-island cotton fields had no ditches dividing them permanently into task units; but the fact that each of these in its day was often combined with rice on the same plantations, and that the separate estates devoted to them respectively lay in the region dominated by the rice regime, led to the prevalence of the task system in their culture also.  The soils used for these crops were so sandy and light, however, that the tasks, staked off each day by the drivers, ranged larger than those in rice.  In the cotton fields they were about half an acre per hand, whether for listing, bedding or cultivation.  In the collecting and spreading of swamp mud and other manures for the cotton the work was probably done mostly by gangs rather than by task, since the units were hard to measure.  In cotton picking, likewise, the conditions of the crop were so variable and the need of haste so great that time work, perhaps with
