Kirke seized the governor's mansion, then occupied by Hill. In January 1638, the king also granted Kirke a coat of arms, "For the greater honour and splendour of that Countrey and the people therein inhabiting … to be used in all such cases as Armes are wont to be by other nations and Countries." In 1639, Kirke renamed the colony the Pool Plantation. Over the next several years, he built forts at Ferryland, St. John’s, and Bay de Verde. He collected tolls from all fishing vessels.
