"On his arrival at Ust-janskoe Simovie, the port at which he was to embark, he sent an account, dated February 2, 1715, to the Chancery of Jakutzk, mentioning that it was impossible to navigate the sea, as it was continually frozen both in summer and winter; and that consequently the intended expedition was no otherwise to be carried on but with sledges drawn by dogs. In this manner he accordingly set out, with nine persons, on the 10th of March the same year, and returned on the 3d of April, to Ust- janskoe Simovie. The account of his journey is as follows: That he went seven days as fast as his dogs could draw him, (which, in good ways and weather, is eighty or a hundred wersts in a day) directly towards the north, upon the ice, without discovering any island; that it had not been possible for him to proceed any farther, the ice rising there in the sea like mountains; that he had climbed to the top of some of them, whence he was able to see to a great distance round about him, but could discern no appearance of land; and that at last wanting food for his dogs, many of them died, which obliged him to return." Besides these arguments, which proceed upon an admission of the hypothesis, that the ice in those seas comes from the rivers, there are others which give great room to suspect the truth of the hypothesis itself. Captain Cook, whose opinion respecting the formation of ice had formerly coincided with that of the theorists we are now controverting, found abundant reason, in the present voyage, for changing his sentiments. We found the coast of each continent to be low, the soundings gradually decreasing toward them, and a striking resemblance between the two; which, together with the description Mr Hearne gives of the copper-mine river, afford reason to conjecture, that whatever rivers may empty themselves into the Frozen Sea, from the American continent, are of the same nature with those on the Asiatic side, which are represented to be so shallow at the entrance, as to admit only small vessels; whereas the ice we have seen rises above the level of the sea to a height equal to the depth of those rivers, so that its entire height must be at least ten times greater.
