No doubt all outsiders are guilty of trespass, especially those who violate the domains of specialists, but as far the Northwest Passage and my own experiences are concerned, here I will claim - to some extent at least - to know whereof I speak.It was in fact my lot to spend almost two decades in the Canadian Arctic, firstly on the east and west coasts of Hudson Bay, on James Bay, and then at a variety of locations largely along the lower reaches of the Northwest Passage itself.During these years I lived on the east and west coasts of Baffin Island; on the coasts of Melville and Boothia Peninsulas, on Jenny Lind Island, on the southern coast of Victoria Island, on the mainland coast of the Barren Lands; at Cape Parry at the mouth of the Beaufort Sea, further west at Nicholson Peninsula, then Tuktoyaktuk, and two more locations further west again along the Yukon coastline.

It was a rainy, sunless place, where the inhabitants lived by agriculture.
They grew millet, which they threshed in covered barns, and supplemented their diet with herbs, roots and berries.

Nevertheless, as Map 1a above shows, few lengthy voyages are required to reach Greenland from Europe or the Mediterranean in any case.
