148 ORANGE CULTURE IN CALIFORNIA. 



old, on low damp ground, are killed. Many of the older trees 

 in the low lands have the leaves all killed, but they will put 

 forth new leaves. 



Fourth This is the first year in which trees have suffered to 

 any extent in this county. The damage has not been sufficient, 

 even this season,* to discourage the cultivation of oranges and 

 lemons on t*he higher ground.* 



P. S. Russell, Riverside : 



First On one or two mornings, twenty-seven degrees ; gen- 

 erally, twenty-eight to thirty degrees. About twenty mornings 

 the thermometer fell below freezing; very unusual for this place. 



Second No material damage except on very low lands. Age 

 of trees, from three to ten years. Generally speaking, no dam- 

 age at all to orchard trees. Budded trees in nursery are hurt 

 in some places ; in others, not. 



Fourth No ; in proof of which see the thousands of orange 

 and lemon trees on every hand, as green and fresh as ever, 

 many of them loaded with golden fruit of the finest of any in 

 the State. 



San Diego County Thomas L. Nesmith, San Diego: 



First In San Diego the lowest thermometer was between 

 midnight and sunrise; from forty-six down to thirty-six degrees. 

 It was from five to ten degrees lower in the neighboring valleys, 

 being lowest at one or two points in the Cajon Valley, sixteen 

 miles distant. There are in nursery in this valley many young 

 lemon and orange trees which suffered from the frost. 



Second The principal damage, if not the only damage, was 

 done to young trees in nursery in Cajon Valley. Five thousand 

 dollars is certainly the extreme limit of the damage done. Bear- 

 ing trees were not perceptibly affected anywhere. The trees in 

 town and on National ranch received no damage worth men- 

 tioning. All trees on high or mesa land, even the youngest in 

 nursery, escaped uninjured. 



Fourth They have not. No remembrance of any such 

 weather in any previous winter. Frost is a very remarkable 

 phenomenon here. 



The conclusion to be drawn from this mass of testimony is, 

 that orange growing is no longer an experiment in the north,
