IRRIGATION AND METEOROLOGY. 
METEOROLOGICAL OB SKRVATIONS. 
The last report of this department gave a summary of the ob¬ 
servations for the year, to June 1st. Only a few of the more im¬ 
portant facts of the subsequent record, therefore, -will be given in 
this bulletin. 
The following instruments have recently been added to the 
equipment of the station: Self registering barometer and ther¬ 
mometer, solar and terrestrial radiation thermometers and sun¬ 
shine recorder. 
From the record of the registering thermometer, the coldest 
period at night is between 5 and 6 a. m., the temperature falling 
steadily to that hour. The hour of maximum temperature is not 
so well defined, but is usually about 3p. m. The mean maximum 
temperature for June and July was 84 degrees, and the mean mini¬ 
mum temperature 53 degrees, giving a mean daily range of 31 
degrees. 
The mean maximum temperature in the sun was 148 degrees, or 
64 degrees above that of the shade. The mean temperature of the 
terrestrial radiation thermometer was 45 degrees, or 8 degrees 
below the mean minimum.
