In his first instrument Day arranged for this wire to pass around a
pulley, the revolution of which actuated the pen of the recording
drum. This should have been successful but for the difficulty of
making good mechanical connection between the recorder and the
pulley. Backlash caused an unreliable record, and this arrangement
had to be abandoned. The motion of the wire was then made to actuate
the recorder through a hinged lever, and this arrangement holds, but
days and even weeks have been lost in grappling the difficulties of
adjustment between the limits of the tide and those of the recording
drum; 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 deg.. 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.
