160 PROCEEDINGS OF TWENTY-SIXTH FRUIT-GROWERS' CONVENTION. 



Rhamnus is a very easy plant to spray thoroughly. The spraying of 

 the vine would have to be done during the busy season, while the other 

 generation can be sprayed at leisure. 



The method that will be usually adopted for the extermination of 

 this insect, however, is not by spraying, but by the destruction of the 

 winter food-plant, since it is of no value and could be easily cut out. 



Upon motion, the paper by Professor Woodworth was received and 

 placed on file.

WHAT OALIFOENIA HAS DONE FOE HOETICULTUEE. 



By ALEXANDER CRAW, 

 Qaarantine OflBcer of the State Board of Horticulture. 



Not only in the United States, Canada, Central and South America, 

 but also in Europe, Australia, New Zealand, South Africa, and other 

 countries, California is recognized as the most advanced horticultural 

 country in the world. Representatives from all parts of the civilized 

 world have been sent to this State, in most instances by their Govern-

 have been copied, and other countries have been benefited by the enter- 

 prise of our people. Not only have new varieties of fruits been originated 

 here, but some of the older sorts, under our improved system, take on 

 characteristics that commend them to the eye and palate of the people 

 of other countries. 



In this short paper I will not attempt to enumerate the great number 

 of choice fruits and flowers that have been brought into existence by 

 artificial methods, or by the improved system of conducting all horti- 

 cultural operations in this State, but will confine myself to what has 

 been done to prevent the introduction of insect pests, also to the artifi- 

 cial and natural methods of controlling those that were imported before 

 any restrictions were placed upon trees and plants entering the State. 



California was the first State to pass laws for the promotion and pro- 

 tection of horticulture. This was in 1881. The horticultural law was
