And therefore it seemeth that this north-east sea is maintained by the river Ob, and such like freshets as the Pontic Sea and Mediterranean Sea, in the uppermost parts thereof by the river Nile, the Danube, Dnieper, Tanais, etc.
9.

Furthermore, if there were any such sea at that elevation, of like it should be always frozen throughout--there being no tides to hinder it--because the extreme coldness of the air in the uppermost part, and the extreme coldness of the earth in the bottom, the sea there being but of small depth, whereby the one accidental coldness doth meet with the other; and the sun, not having his reflection so near the Pole, but at very blunt angles, it can never be dissolved after it is frozen, notwithstanding the great length of their day: for that the sun hath no heat at all in his light or beams, but proceeding only by an accidental reflection which there wanteth in effect.
10.

And yet if the sun were of sufficient force in that elevation to prevail against this ice, yet must it be broken before it can be dissolved, which cannot be but through the long continue of the sun above their horizon, and by that time the summer would be so far spent, and so great darkness and cold ensue, that no man could be able to endure so cold, dark, and discomfortable a navigation, if it were possible for him then and there to live.
11.

Further, the ice being once broken, it must of force so drive with the winds and tides that no ship can sail in those seas, seeing our fishers of Iceland and Newfoundland are subject to danger through the great islands of ice which fleet in the seas, far to the south of that presupposed passage.
12.

And it cannot be that this North-East Passage should be any nearer the south than before recited, for then it should cut off Ciremissi and Turbi, Tartarii, with Vzesucani, Chisani, and others from the continent of Asia, which are known to be adjoining to Scythia, Tartary, etc., with the other part of the same continent.
And if there were any through passage by the north-east, yet were it to small end and purpose for our traffic, because no ship of great burden can navigate in so shallow a sea, and ships of small burden are very unfit and unprofitable, especially towards the blustering north, to perform such a voyage..
