Now, originally, the Pilgrims intended to come, not to Massachusetts, but to settle at the mouth of the Hudson. Unfortunately, by then the Hudson was in Dutch hands. An alternative was the St. Lawrence, but that route was under tight French control, where Champlain had founded his Québec colonies. But the Kennebec, in what is now Maine, was available. And as Bradford explains, in about 1625 – '26, men from Boston began to make forays up that river. The area became crucial in 1628, when they founded a satellite trading post at what is now Maine's capital, Augusta, to barter European goods with Native Americans in exchange for beaver pelts. (And Boston governed Maine for the next 200 years, until 1830.). ....
.... By the late 1620s, when the war with France was going so badly, fur prices quadrupled in a single year. And suddenly everything came together. The Pilgrims had founded their trading posts with Native Americans. They had gained access to the interior tribes by controlling the rivers, particularly to the north in Maine. Beaver prices had skyrocketed. The merchants in Barnstaple were eager to do business with the Pilgrims because trade with France had collapsed. The Pilgrims desperately needed to pay their debts, which by now were enormous. ...
So, when the investors and merchants in London put two and two together, they turned into hearty supporters of colonization in general. England's "Long Hesitation" was over. Within a single generation, America's population surged past 100,000, and the next generation saw that number double again.
New England was going to be a success, after all.
