Dugua was directed "to establish the name, power, and authority of the King of France; to summon the natives to a knowledge of the Christian religion; to people, cultivate, and settle the said lands; to make explorations and especially to seek out mines of precious metals." Armed with this grandiose mission, Dugua, his navigator Samuel Champlain, and his crew sailed to North America. There they established an ill-fated French settlement on Saint Croix Island, located on the present-day Maine/New Brunswick border.
Dorr's work at Sieur de Monts Spring symbolizes the enthusiasm and spirit of many early 20th-century summer residents who worked to preserve and protect the natural and historic values of Mount Desert Island. In a sense, Sieur de Monts Spring has become a memorial to Dorr, for it was his inspiration and determination that led to the creation of Acadia National Park.
