How were Slaves prepared for sale?

As the slave ship came in sight of land the slaves were prepared for yet another sale. Those who had not died and were not too feeble to move were cleaned and oiled to make them look strong and healthy. In some ports the planters and buyers came on board ship to make their choice of the best slaves. More often slaves were sold by public auction on the towns. The planters might pay the captains in local money or give them credit notes to collect the money in Europe. More often the slaves were exchanged for sugar and plantation produce. There was usually much argument over the amounts to be paid depending on what the price for sugar was or whether the demand for slaves was high.
