art of the world, and each
of them opening but on one part to the main sea, do likewise receive
their increase upon the flood the same way, and none other, which the
Frozen Sea doth, only by the west, as Master Jenkinson affirmed unto me,
and therefore it followeth that this north-east sea, receiving increase
only from the west, cannot possibly open to the main ocean by the east.

7. Moreover, the farther you pass into any sea towards the end of it, of
that part which is shut up from the main sea, as in all those
above-mentioned, the less and less the tides rise and fall. The like
whereof also happeneth in the Frozen Sea, which proveth but small
continuance of that sea toward the east.

8. Also, the farther ye go towards the east in the Frozen Sea the less
soft the water is, which could not happen if it were open to the salt sea
towards the east, as it is to the west only, seeing everything naturally
engendereth his like, and then must it be like salt throughout, as all
the seas are in such like climate and elevation. 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 d
