are 56 clear periods and 58 cloudy, which is a remarkably even 

 balance. 



In 1900 there were 10 more observations marked "clear" than 

 cloudy, while in 1901 cloudy periods were somewhat more frequent 

 than clear. Taking observations for both years, we have the pe- 

 riods pretty evenly divided. 



These observations show that, taken as a whole, the cloudy pe- 

 riods and clear periods are about equally divided, the clear periods 

 being more prevalent in 1900 but less so in 1901. North and west 

 winds are relatively infrequent ; winds from other directions are so 

 evenly balanced that none can be called the prevailing wind. This 

 is an evenly tempered uneventful month and the minor weather 

 phenomena such as fog, haze, electrical storms, etc., were not suf- 

 ficiently marked to attract especial attention. 



Rainstorms are not especially frequent during this month. 



The results of our observations are given in the following table : 



Tem'peratures: — The total number of temperature records for 

 June is 202, as follows: 90 in 1900, 90 in 1901, 10 in 1902, and 12 

 in 1903.

 1903% 62° on June 27 and 86.2° on June 30; range 24.2°. 



Our records show no freezing temperature for June. The 

 greatest daily range was as follows : 



June 9, 1900, from 54° to 80°, or 26°. 



June 16, 1901, from 65° to 90°, or 25°.
