of which might have been saved if we had looked after them in time. But the men have grown so indifferent to the pressure now that they do not even go up to look, let it thunder ever so hard. They feel that the ship can stand it, and so long as that is the case there is nothing to hurt except the ice itself. "In the morning the pressure slackened again, and we were soon lying in a large piece of open water, as we did yesterday. To-day, again, this stretched far away towards the northern horizon, where the same dark atmosphere indicated some extent of open water. I now gave the order to put the engine together again; they told me it could be done in a day and a half or at most two days. We must go north and see what there is up there. I think it possible that it may be the boundary between the ice-drift the Jeannette was in and the pack we are now drifting south with--or can it be land? "We had kept company quite long enough with the old, now broken-up floe, so worked ourselves a little way astern after dinner, as the ice was beginning to draw together. Towards evening the pressure began again in earnest, and was especially bad round the remains of our old floe, so that I believe we may congratulate ourselves on having left it. It is evident that the pressure here stands in connection with, is perhaps caused by, the tidal wave. It occurs with the greatest regularity. The ice slackens twice and packs twice in 24 hours. The pressure has happened about 4, 5, and 6 o'clock in the morning, and almost at exactly the same hour in the afternoon, and in between we have always lain for some part of the time in open water. The very great pressure just now is probably due to the spring-tide; we had new moon on the 9th, which was the first day of the pressure. Then it was just after mid-day when we noticed it, but it has been later every day, and now it is at 8 P.M." The theory of the ice-pressure being caused to a considerable extent by the tidal wave has been advanced repeatedly by Arctic explorers. During the Fram's drifting we had better opportunity than most of them to study this phenomenon, and our experience seems to leave no doubt that over a wide region the tide produces movement and pressure of the ice. It occurs especially at the time of the spring-tides, and more at new moon than at full moon. During the intervening periods there was, as a rule, little or no trace of pressure. But these tidal pressures did not occu
