[8] 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, 1753, he is expected in
      Barbadoes, as the consignees write.  They also state that
      slaves are selling at L33 to L56 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 L1,324 3_d._ The captain
      then took on board 55 hhd. of molasses and 3 hhd. 27 bbl. of
      sugar, amounting to L911 77_s._ 21/2_d._, 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. American Historical
