122 ORANGE CULTURE IN CALIFORNIA. 



Sonoma County Q. C. Smith, M. D., Cloverdale: 



First Lowest, twenty-two, twenty-four, twenty-six, twenty- 

 eight, thirty and thirty-one degrees. Twenty-nine degrees is 

 the lowest we have had before this winter for six or eight years 

 past, and thirty-two degrees is as low as we ordinarily have in 

 winter. 



Second The damage to orange and lemon trees several years 

 old was very slight ; young trees suffered more, on which the 

 most tender exposed shoots or buds were killed, but not enough 

 to compromise the life of the tree. Pepper trees suffered as 

 much as orange trees or more. 



Third The above refers to trees in Cloverdale, and which 

 ae on low ground in Russian River Valley, where the frosts are 

 more severe than in higher localities, 



Fourth No. We have raised and do raise oranges without 

 protection. Lemons could be raised successfully in many ele- 

 vated localities near this place, but in Cloverdale it is rather too 

 cold during our coldest winters for them to thrive and bear, 

 though they grow well here. 



S. A. Marshall, Healdsburg: 



First Thermometer from twenty to twenty-six degrees. 



Second First or spring growth uninjured, but the growth 

 the tree makes in the fall, after the early rains, is badly frost- 

 bitten. Leaves and young growth appear scalded. Mediter- 

 ranean Sweet and Konah not injured so much as Los Angeles 

 and Acapulco. Lemons injured very little, only leaves affected 

 by frost. 



Third Trees planted last spring on hill land, and about 

 three years old. One Mediterranean Sweet, planted last spring, 

 fruited ; the oranges were not injured by frost. Older trees in 

 the vicinity, and on the same kind of land, uninjured compara- 

 tively, and bearing fruit. We have the guava growing, which 

 was planted two years ago. It is doing well, the frost not having 

 affected it. 



Col. J. B. Armstrong, Santa Rosa : 



First Mean temperature in this valley at sunrise for Decem- 

 ber, 1878, the coldest month, thirty-two and one-half degrees ; 

 December 2;th, the coldest morning, eighteen degrees. In the
