ORANGE CULTURE IN CALIFORNIA. 139 



Second Six-year-old trees on high lands are slightly hurt; 

 they will shed their leaves. Trees ten and twelve years old, on 

 the same ground, are not injured in any respect. Trees are a 

 failure on low lands. 



Fourth On high lands with water their cultivation is a 

 success. 



Sati Luis Obispo County B. R. Harris, San Luis Obispo : 



First The mean readings of the thermometer at the County 

 Hospital, situated on an elevated plateau perhaps eighty feet 

 above the surrounding plain, for two months ending January 

 2oth were : at eight A. M., forty-seven degrees ; at M., fifty-seven 

 degrees; and at eight P. M., fifty degrees; highest, sixty-nine 

 degrees ; lowest, forty degrees ; lowest in the valley, thirty-six 

 degrees. 



Second No damage to speak of has been sustained, except 

 in rare cases, and then it was confined to seedlings one year 

 old, planted on low, moist ground, and in cases in which the 

 young plants had attained an exceptionally rank and tender 

 growth. Those planted on elevated dry land have entirely es- 

 caped. Orange trees have in the latter case been blooming and 

 bearing fruit all winter. 



Fourth A strip of country lying along the western base of 

 Santa Lucia or Coast Range, bordering on the open coast lands, 

 and averaging three miles in width, and extending from Cam- 

 bria on the northwest to the Santa Maria river on the southeast, 

 is almost entirely free from frost. Oranges and lemons can be 

 successfully cultivated within said described limits. 



Santa Barbara County Ellwood Cooper, Santa Barbara 

 county : 



First Lowest point indicated by thermometer on my ranch, 

 thirty-four degrees. I have only a few orange and lemon trees ; 

 no apparent injury was done to any of them. All are protected, 

 however, by forest trees. 



Second I have not examined any trees of either of the above 

 varieties, except the orchards of Col. W. W. Hollister, in which 

 there was no apparent injury. I have understood that in Santa 

 Barbara nearly all the young growth on young trees was killed.
