A typical voyage is that of the brigantine " Sanderson " of Newport. She was fitted out in March, 1752, and carried, beside the captain, two mates and six men, and a cargo of. 8,220 gallons of rum, together with " African " iron, flour, pots, tar, sugar, and provisions, shackles, shirts, and water.

Proceeding to Africa, the captain after some difficulty sold his cargo for slaves, and in April, 1 753, he is expected in Barbadoes, as the consignees write. They also state that slaves are selling at £33 to £$6 per head in lots. After a stormy and dangerous voyage, Captain Lindsay arrived, June 17, 1753, with fifty-six slaves, "all in helth & fatt." He also had 40 oz. of gold dust, and 8 or 9 cwt. of pepper. The net proceeds of the sale of all this was .£1,324 $d.

The captain then took on board 55 hhd. of molasses and 3 hhd. 27 bbl. of sugar, amounting to ^911 17J. lYid., received bills on Liverpool for the balance, and returned in safety to Rhode Island. He had done so well that he was immediately given a new ship and sent to Africa again.
