ABSTRACT
The highest colour is delicate blew, of the same colour with the blewest vitriol, somewhat more transparent, yet not so clear as that in our country, which you may see through let it be never so thick; it is as hard as a stone, and it is not easily split or cleav'd, because it is spungy, like unto pumice stone. Among the ice the ships sail up and down until they come to bigger ice-fields, for the small ones encumber the sea, that the ships sail often against them and perish; for when the winds arise the waves drive against the ice-fields, as it was against rocks, and beat the ships to pieces.
