EXPERIMENT STATION BULLETINS. 743 



THE DAILY AND MONTHLY MAXIMUM AND MINIMUM TEMPERATURE AND THE 



MONTHLY AMPLITUDE. 



Thus far the average daily march of average temperature of the various 

 types of soil has been considered. It will now be of interest to examine 

 the daily maximum and minimum temperature and consequently also 

 the amplitude of these same classes of soil. The data for the three 

 years are included in Tables 39 to 74 inclusive. As previously stated 

 these maximum and minimum temperatures do not represent the abso- 

 lute values, but they approach these actual or true values very closely.
