Thus in 1831 James L.Pettigru and Langdon Cheves sent from Charleston to Savannah 85 and 64 slaves respectively of ages ranging from ninety and seventy years to infancy, with obvious purpose to develop newly acquired plantations in Georgia.

Most of the non-commercial shipments, however, were in lots of from one to a dozen slaves each.

The traders' lots, on the other hand, which were commonly of considerable dimensions, may be somewhat safely distinguished by the range of the negroes' ages, with heavy preponderance of those between ten and thirty years, and by the recurrence of shippers' and consignees' names.

The Chesapeake ports were the chief points of departure, and New Orleans the great port of entry.
Thus in 1819 Abner Robinson at Baltimore shipped a cargo of 99 slaves to William Kenner and Co.

at New Orleans, whereas by 1832 Robinson had himself removed to the latter place and was receiving shipments from Henry King at Norfolk.
