1911] then when all seemed well we found that the floe was not rising uniformly with the water. It is hung up by the beach ice. When we were considering the question of removing the whole apparatus to a more distant point, a fresh crack appeared between it and the shore, and on this ‘hinge’ the floe seems to be moving more freely.

Friday, June 30, 1911.—The temperature is steadily falling; we are descending the scale of negative thirties and to-day reached its limit, −39°. Day has manufactured a current vane, a simple arrangement: up to the present he has used this near the Cape. There is little doubt, however, that the water movement is erratic and irregular inside the islands, and I have been anxious to get observations which will indicate the movement in the ‘Strait.’ I went with him to-day to find a crack which I thought must run to the north from Inaccessible Island. We discovered it about 2 to 2½ miles out and found it to be an ideal place for such work, a fracture in the ice sheet which is constantly opening and therefore always edged with thin ice. Have told Day that I think a bottle weighted so as to give it a small negative buoyancy, and attached to a fine line, should give as good results as his vane and would be much handier. He now proposes to go one better and put an electric light in the bottle.

We found that our loose dogs had been attacking a seal, and then came across a dead seal which had evidently been worried to death some time ago. It appears Demetri saw more seal further to the north, and this afternoon Meares has killed a large one as well as the one which was worried this morning.
