There was not time to make a satisfactory set of observations on needle No.2. When 
the above were finished we left this station. 
Weather cloudy. Occasionally a slight fall of snow. The snow is now two feet deep 
upon the ground. 
The instrument was placed on the stand, (the trunk of a tree sunk four feet into the 
ground,) lately occupied by the altitude and azimuth instrument used for determining 
the latitude of this position, over which was a tent free from iron in any shape.
