ORANGE CULTURE IN CALIFORNIA. 129 



Third Trees that have been growing for more than one 

 season have not been injured much, if any, so far as my obser- 

 vation goes. Bearing trees not at all. 



Fourth There is no doubt that oranges can be successfully 

 cultivated here. The trees that bear prolifically are numerous, 

 and, until this season, not much trouble has been experienced 

 on account of frost. 



Daniel Winter, Union Island : 



First From the I4th of December to the 26th the ther- 

 mometer ranged from twenty-four to twenty-eight degrees. On 

 the 26th it reached the lowest temperature, twenty-two degrees ; 

 27th, 28th and 29th thermometer stood at twenty-six degrees at 

 half-past six o'clock A. M. 



Second My orange trees, also my neighbors', have had 

 nearly all of last year's wood killed, but I think that by cutting 

 back they will be as good as though they had not received any 

 injury from frosts. 



Third All the ground about me is only five feet above tide 

 water. Age, two and three years. 



Fourth If all our winters were as severe as this, we could 

 not raise oranges and lemons without protection; but for the 

 last ten years prior to this winter they would have stood the 

 frosts without severe damage. 



Contra Costa Coimty Dr. J. Strenzel, Alhambra : 



First My thermometer is always kept on the north side of 

 the house. Its previous lowest reading was twenty-six degrees, 

 some years ago. This winter the lowest was twenty-four, then 

 twenty-six, then twenty-five, then twenty-eight, and recently 

 from twenty-nine to thirty-four degrees, observed at about six 

 o'clock A. M. 



Second My oldest orange and lemon trees have not suffered 

 in the least, though here and there a tender young leaf is shriv- 

 eled. The fruit looks sound. The old citron tree, which had 

 often been frost-bitten and appeared most tender, stood nearly 

 as well as the oranges this time. A young orange orchard of 

 eight hundred trees, third year since transplanting, was brushed 

 in after the cold began ; it is not materially injured. Some rows 

 nearest a eucalyptus wind-break are entirely untouched. Sev-
