This comparison shows that both the maximum and the minimum 

 temperatures in Australia are higher than in Florida, and that the 

 total annual rainfall in Florida is much greater than in any part of 

 Australia. 



The greatest difference between the climates of Florida and of 

 southern California, in the zones of the two States in which the cul- 

 ture of eucalyptus is possible, is in the amount of precipitation and its 

 distribution throughout the year. This difference, however, affects 

 the relative humidity of the air and therefore modifies the effect of 

 the temperature upon vegetation. The differences may be summar- 

 ized as follows: 



1. In southern California the maximum temperature is over 10° 

 higher than it is in Florida, but the air is dry. Southern California, 

 average maximum temperature, 108.6° ; Florida, average maximum 

 temperature, 98°. 



2. The minimum temperatures are very nearly the same. Southern 

 California, average minimum temperature, 21° ; Florida, average 

 minimum temperature, 21.2°. 



3. The average annual precipitation is much greater in Florida. 

 Southern California, average annual precipitation, 18.9 inches; Flor- 

 ida, average annual precipitation, 54.1 inches. 



4. The relative humidity is much greater in Florida. 



5. In southern California the rainy season comes in the winter 

 months (December, January, and February), while in Florida the 

 heaviest rainfall occurs in the summer months (June, July, and 

 August), but the total precipitation is more evenly distributed
