The following table gives the mean temperature, the extremes of tempera- 

 ture, the velocity of the wind, the percentage of cloudiness, the relative 

 humidity, and the rainfall, for each month of the year 1878. 



SUMMARY FOR THE YEAR 1879. 

 The chief characteristics of the weather of 1879 were the high average 

 temperature of the spring and autumn months, the long period of immunity 

 from severe frost, the deficient rainfall of March, May and August, the extra- 

 ordinary rainfall of November, and the low percentage of cloudiness. It is 

 worthy of note that, notwithstanding the deficiency of rain in the months 

 above named, the crops have been abundant in all the agricultural sections 

 oi the tttaLe.
