ORANGE CULTURE IN CALIFORNIA. 119 



H. W. Hurlburt, Auburn: 



First The lowest known reading of the thermometer this 

 winter was twenty-six degrees Fahrenheit in Auburn, and twenty- 

 seven degrees in my neighborhood. 



Second No damage at all has been done, except in a few 

 localities, where the leaves are killed. It is not thought that a 

 single orange or lemon tree, even though just set out, has been 

 killed. 



Third The high ground is the best and it is generally used. 

 Most of the trees about here were planted last year. 



Fourth This is by far the coldest winter ever known here. 

 The trees were wholly unprotected. There are many places 

 here where even tomato vines flourish uninjured throughout the 

 year in ordinary winters. 



Yolo County}. R. Wolfskill, Winters : 



First I cannot say, as I had no thermometer at that time. 

 The ice was probably three-eighths or one-half inch thick sev- 

 eral mornings. 



Second I cannot state the extent of the damage as the trees 

 may come out all right in the spring. I think it is slight and 

 confined to late growth on young trees. The leaves at the ends 

 of young shoots are dried at present ; this is all the damage 

 visible. 



Third Both high and low ground. Of course the frost affects 

 the young trees more on low ground than on high. The ages of 

 the trees, from twenty-two years down. 



Fourth No. I have been cultivating orange trees since 

 about 1850 and have not lost a tree by frost.
