BALTIC SEA, a great gulph surrounded by Sweden, Russia, Courland, Prussia, Pomerania, and Denmark. The king of Denmark levies a tax at Elsinour on every ship that enters the Baltic sea. It is remarkable that this sea neither ebbs nor flows, and there is always a current sets through the Sound into the ocean. It is generally frozen over three or four months in the year. Yellow amber is found in plenty on this coast.
