Began ten minute observations as soon as I was called and continued them for about three hours both morning and afternoon. To do this and get breakfast at the same time required some fast work. With the thermometer at -40 below zero this was great sport!
Got some interesting results showing that the tide fluctuates back and forth according to the cracking of the ice. Could not get Jack out at 2 o’clock so ran my watch to four getting supper for him. To save wood will let fire go out tonight and burn one side of oil stove.
