the port of Valencia alone over 3,000,000,000 oranges have 

 been shipped in the course of one season. The fruits, which 

 are considered the best of their kind in Europe, can now be 

 delivered in England at gs. the box, leaving a fair margin of 

 profit to the producer."

In the Gardeners' Chronicle of July 17, 1886, p. 77, there is 

 the following : 



" Orange culture in S. Francisco. In a recent Government 

 report on the products of S. Francisco, it is stated that there 

 are about 12,000 acres planted in orange trees in Los 

 Angelos county, now bearing fruit, and several thousand 

 acres in young trees, which will begin to bear fruit in from 

 two to five years' time. In S. Bernardino county, the orange 

 crop has, at intervals of from three to four years, been greatly 

 damaged by frost. At less frequent intervals, the same 



trouble has been experienced in this county Oranges

 their admission free of duty would cripple the industry here. 



"The 'white scale' is still doing immense damage to the 

 orange trees. Some of the oldest orange orchards in the 

 country are being topped and pruned to such an extent that 

 they will not bear any fruit for several years. In some cases 

 the trees are being cut down. No cheap effectual remedy 

 has as yet been discovered to destroy the insect ; it is stated, 

 however, that another insect has appeared which preys on 

 the 'white scale,' and is not injurious to the orange tree." 



NOTE. There can be little doubt that when large tracts 

 of any country are covered with one kind of plant, sooner or 

 later some insect or vegetable parasite that feeds upon it, 

 will appear whether the plant be that of the orange, the
