ORANGE CULTURE IN CALIFORNIA. 147 



Third The orchards are on level or low land, there being no 

 hill in the vicinity of Los Angeles. [There are some low hills 

 in the northern part of the city and more to the north and east, 

 yet but very few trees are planted on them, some of them having 

 no water. AUTHOR.] 



Fourth Many farmers have planted Mexican limes for fences. 

 It can be said that all or nearly all are lost. Some have been 

 preserved without injury, but they were protected by other trees, 

 as willows, etc. 



W. R. Olden, Anaheim : 



First December i8th, thirty-three degrees ; igth, thirty-three 

 degrees; 25th, thirty-two degrees; 1879, January Qth, thirty- 

 four degrees ; loth, thirty-two degrees ; i ith, thirty-four degrees ; 

 1 5th, thirty-one degrees; taken from a self-registering ther- 

 mometer in an orange grove in the open country outside of 

 Anaheim. (No cold weather since January I5th.) 



Second No orange or lemon tree within a circle with a ra- 

 dius of five miles from Anaheim has been frosted in the slightest 

 degree. Even lime trees, bananas, tomato and potato vines are 

 untouched. Oranges and lemons have never been injured in 

 Anaheim. It is protected by a range of hills north of town, and 

 which keep off the mountain wind. 



Third All ages, from small seedlings to old bearing trees. 

 From eighty to two hundred and fifty feet above the sea level. 

 The hills protect all alike. 



Fourth Neither orange nor lemon trees have ever been in- 

 jured in Anaheim or vicinity by a winter frost. A few trees on 

 the outside were injured by an April frost in 1875, but they were 

 not materially damaged. That is the only instance of damage 

 in this city in twenty-nine years. 



San Bernardino County Dr. Barton, San Bernardino: 



First In the lower lands in this county, as low as twenty-five 

 degrees in this neighborhood. At Old San Bernardino, that 

 being bench land, it did not go lower than thirty degrees. 



Second No damage was done to orange and lemon on high 

 lands, except to the leaves and tender young shoots on trees 

 under three years old. Older trees, and even young ones with 

 wood well matured, have not suffered. Trees under four years
