This trade is still active on some parts of the coast of Africa. There are several steamers engaged in carrying slaves from the coast, and they are too swift for the slow English cruisers. These steamers are rigged and painted so as to resemble the English mail steamers which run the coast. They have been seen and chased several times, but not one of them has yet been captured. It was reported a short time ago that there were 1500 slaves at Whydah awaiting shipment. One of these steamers was seen to come in twice to attempt their shipment, but she was so closely pursued by the cruisers that she put to sea both times, without accomplishing her object.
