114 ORANGE CULTURE IN CALIFORNIA. 



years old, and has been bearing for eight years ; two full crops 

 each year. 



Fourth They have not. We are having the most severe 

 frosts this winter ever known in this section of the country. I 

 have sold hundreds of trees, but I never knew one to die from 

 frost or cold weather. 



Butte County]. B. Ketchum, Bidwell's Bar: 



First Lowest, twenty-four to twenty-eight degrees most of 

 the time. At night, twenty-nine to thirty-two degrees. 



Second When frost strikes the leaves, they fold up and ap- 

 pear to be badly injured, but moist weather restores their ap- 

 pearance. The leaves turn yellow in part, especially on the 

 south side of the tree. 



Third Thirty feet above low-water mark, north side of hill 

 (Feather river). One tree twenty-four years old. 



Fourth The hardier orange tree, such as Los Angeles and 

 Acapulco, will succeed in proper soil. In February, 1862, the 

 thermometer stood twenty-one degrees, and although there was 

 eight inches of snow on the ground, no injury was done to the 

 trees. Lemon trees are injured. 



Colusa County L. F. Moulton, Colusa : 



First I am informed that the lowest tern perature was 

 eighteen degrees, but the greatest damage was done after that 

 by very heavy frost with higher temperature. Ice formed an 

 inch thick. 



Second I have two hundred and fifty six-year-old orange 

 trees, and some lemon, lime and citron trees, on medium low 

 ground, common soil. Leaves and ends of young twigs partly 

 frosted, but not seriously damaged. 



Fourth I have been experimenting on a small scale for 

 eighteen years, and think they should be protected by hedges, 

 fences or buildings, to prevent the hot sun from melting the frost 

 before the warmth of the atmosphere has taken it out in the 

 morning. I also advise planting in a place sheltered as much 

 as possible on all sides. I have one bearing tree that froze 

 nearly to the ground in 1872, but it has again commenced bear- 

 ing superior oranges this year. It has never been protected 

 only as above stated. I have one other bearing tree which froze
