The year 1614 opened with a visitor to Plymouth from a new quarter. Dutch fur traders, following in the wake of Henry Hudson’s 1609 discoveries, were already at work in the Hudson River. Two of them, Adrian Block and Hendrick Christiansen, were about to weigh anchor from Manhattan and depart for the Netherlands with a cargo of furs in the fall of 1613 when one of their ships caught fire and burned to the water’s edge. Both crews therefore stayed over the winter on Manhattan Island, and there built a new “yacht,” the _Onrust_, which they felt must be given a shakedown cruise before attempting the Atlantic crossing. Block therefore sailed her eastward, the first passage of Long Island Sound by a European, and explored the Connecticut shore and rivers, Narragansett Bay and the Cape Cod region, to all of which he laid claim for the Dutch as “Nieu Nederlant.” Contemporary Dutch accounts offer us little of interest about the Massachusetts phases of this voyage except some sailing directions in Massachusetts Bay that suggest that Adrian Block sailed from a place called Pye Bay, usually identified with Salem, to the Lizard on the English Channel. But the Figurative Map which he published in 1616 as a part of his report to the States General of the Netherlands contains many additional details to which Dutch names are applied, including a wholly unmistakable outline of Plymouth Harbor, here called Cranes Bay. From this it seems obvious that Block did visit Plymouth in the spring of 1614, and may be considered as yet another of its explorers. It would be interesting to know whether any of the Leyden Pilgrims, living in the Netherlands for four years after the map’s publication, ever saw it before setting out for the New World. In view of the controversy over whether the Pilgrims were indeed headed for the Hudson River, it is interesting to note that this map of Adrian Block’s would have been the most accurate one available to them as a guide to the New York region, yet there is nothing in the Pilgrim chronicles to suggest that they had it with them on the _Mayflower_.
