On June 5th the thermometer for the first time stood above freezing-point--viz., at +0.2°. It then fell again for a few days, going down to -6°; but on the 11th it rose again to about 2° above freezing-point, and so on. The amount of atmospheric moisture deposited during the above-mentioned period was most insignificant; only a very slight snowfall now and then. However, Thursday, June 6th, was an exception. The wind, which for several days had been blowing from the south and west, veered round to the northwest during the night, and at 8 A.M. next morning it changed to the north, blowing a fresh breeze, with an exceptionally heavy snowfall. We saw the midnight sun for the first time during the night of April 2d. One of the scientific tasks of the expedition was to investigate the depth of the Polar Sea. Our lines, which were weak and not very suitable for this purpose, were soon so worn by friction, corrosion, oxidation, etc., that we were compelled not only to use them most cautiously, but also to limit the number of soundings far more than was desirable. It sometimes happened that the line would break while being hauled in, so that a good deal of it was lost. The first sounding after the departure of Dr. Nansen and Johansen was taken on April 23d. We thought we should be able to lower away down to 3000 metres (1625 fathoms) in one run, but as the line commenced to slacken at 1900 metres (1029 fathoms) we thought we had touched bottom and hauled the line up again. As it appeared that the line had not reached the bottom, we now let down 3000 metres of line (1625 fathoms), but in doing so we lost about 900 metres of line (487 fathoms). Accordingly I assumed that we had touched ground at 2100 metres (1138 fathoms), and I therefore lowered the line to that depth without touching bottom. The next day we took new soundings at depths of 2100, 2300, 2500, and 3000 metres respectively (1137, 1245, 1353, and 1625 fathoms), but all without touching bottom. On the third day, April 25th, we sounded first at 3000 metres, and then at 3200 metres (1625 and 1733 fathoms) without touching bottom. The steel-line being too short we had to lengthen it with a hemp-line, and now went down to 3400 metres (1841 fathoms). While hauling up we perceived that the line broke, and found that, in addition to the 110 fathoms' length of hemp-line, we had lost about 275 fathoms of steel-line. We then stopped taking soundings till July 22d, as the hemp-lines were so badly worn that we dared not venture to use them again until milder weather set in.
