Table 6 gives the yearly averages of temperature for four different 

 depths. The yearly averages for the depths of 1 and 2 feet are 

 derived from three observations a day, namely, at 8 a.m., 2 p.m., 

 and 8 p.m. ; but the others from one observation a day, at 8 p.m. 

 The averages for the first five years are distinctly higher than those 

 for the last five. I have not any clear idea of what the explanation
