Whenever the weather was in any degree clear or serene, they had scarcely any night; for, being in the middle of January, 1722, the summer was then in its height, and the days at their utmost length.
These mountains of ice, of which they were so much afraid, are certain proofs that the southern countries extend quite to the pole, as well as those under the north; for, without question, these vast hills of ice cannot be produced in the sea, nor formed by the common force of cold. It must therefore he concluded, that they are occasioned by the sharp piercing winds blowing out of the mouths of large rivers.[2] It is no less certain, that the currents discerned in this ocean must all proceed from the mouths of large rivers, which, rolling down from a high continent, fall with such impetuosity into the sea, as to preserve a great part of their force long after they have entered it.[3] The great quantity of birds seen here was an additional proof that land was not far off. It may be asked, whether this land be inhabited or not? For my part I believe it is. It may be again asked, How men should live in such a climate, in the lat. of 70 deg. S. where the winter is so very long, the summer so short, and where they must be involved for so great a portion of the year in perpetual night? To this I answer, That such as dwell there come only in the fine season in order to fish, and retire on the approach of winter, as is done by many of the inhabitants of Russia and of Davis Straits, who, when they have provided themselves with fish on the coasts of a frozen climate, retire farther inland, and eat in their cabins during the winter the fish they have caught in the summer. If the people who inhabit Greenland and Davis Straits are to be believed, the country is inhabited even as high as 70 deg. N. both winter and summer; and what is practicable in one country, cannot justly be reputed impracticable when supposed in another.[4]
[Footnote 2: This is quite erroneous, as it is now well known that the sea water freezes, when reduced to a sufficient degree of cold, considerably lower than what is requisite for freezing fresh water. On this occasion, the salt precipitates from the freezing water, and the ice of sea water is sufficiently fresh for use when melted, if the first running be thrown away, which often contains salt, either adhering to the surface, or contained in cells.—E.]
