“ Adam's journey to this king, undertaken for the express purpose of obtaining information, has been mentioned. He also learned much from Archbishop Adalbert himself, who took great interest in the Northern missions and was well informed about the lands where they were located. Much information was imparted to him also by the traders and missionaries who were continually passing through Bremen, the great centre for all travel to and from the North. Adam assures us repeatedly that he has taken great pains to make his account both truthful and accurate. ”
