*24 ORANGE CULTURE IN CALIFORNIA. 







Bigarde orange trees have been blooming on the highest ground 

 since September. 



Third Both high and lo.w ground. Not a leaf is injured ex- 

 cept on low ground. My trees are from two to twelve years old. 



Fourth General Vallejo, on the east side of the valley, has 

 trees twenty years old, some of which have produced two thou- 

 sand oranges each. Caleb Carriger, Nicholas Carriger, Col. 

 Rodgers and others, on the west side, have thrifty bearing trees. 

 From the success of these cultivators, and my own experience 

 of ten years, I am satisfied that both the orange and the lemon 

 can be profitably cultivated in Sonoma Valley. In the lower 

 portions of the valley frosts are more severe, and young trees 

 will need protection during winters like this. 



Morris Bros., Sonoma : 



First Before sunrise for a number of mornings it marked 

 twenty degrees. The thermometer hung out of doors, within 

 forty feet of the orange grove. 



Second Our trees are badly frosted and now have the gen- 

 eral appearance ^of having been blighted by fire. They will 

 recover, however, as only the tops and leaves are affected. 

 They are growing on low ground, and their average age is seven 

 years. I have a few growing where they are protected by other 

 trees from the winds, which have only their new growth nipped. 

 Some of them now have matured fruit. 



This winter has been the coldest ever known here. Our trees 

 were never hurt by frost heretofore to any extent. The orange 

 and lemon trees on farms adjoining us, but on much higher 

 ground, have never been touched, and are now looking as bright 

 and green as if there had not been any frost. The culture of the 

 orange and lemon is an assured success here, but they must be 

 planted in the foot-hills of the valley. 



Marin County R. J. Trumbull, San Rafael: 



First The lowest temperature at San Rafael during the re- 

 cent "cold snap" was twenty-eight degrees. In Ross Valley, 

 distant about three miles, the thermometer indicated twenty- 

 six degrees. 



Second No serious damage has been done in this county to 

 either the orange or the lemon, so far as I have been able to
