 but during 1915, at 3 and 6 inches. All the records were made three 

 times a day, morning, noon and evening. The time, however, was so 

 chosen and varied during the different seasons as to obtain very close

The data for the first year (1912) has been published in the previous 

 report. In the present paper the results of the other three years will be 

 presented. 



On account of limited space the daily average, maximum and minimum 

 temperature have been eliminated and only the monthly, seasonal and 

 yearly will be presented here. These data are submitted in the following 

 pages.
