PROCEEDINGS OP THIRTY-THIRD FRUIT-GROWERS ' CONVENTION. 133 



ready, he is snapped up by the government service just as soon as he 

 gets to helping Santa Clara County in a way worth while. Carl Morris 

 is tackling bravely the big thrips job in the same county. He needs 

 lime and backing. It is a serious and a large undertaking. He can 

 not go out and begin killing thrips to-morrow. It will only be after 

 weeks and months of close, careful study that he or anybody else will 

 be able to get to killing. But it is his kind of work and Moulton's that 

 in the long run counts most. Tackling the big jobs and going at them 

 from the ground up is the sort of thing we orchardmen sorely need in 

 California. 



Get a man with a couple of assistants; give them living wages; a 

 little office, not large, for out-of-doors will be their principal workroom; 

 and give them time and encouragement to investigate. Don't expect 

 them to wave a stick, or throw dust in the air, or puff smoke out of a 

 covered wagon like the Indian medicine man or a rain-maker. Don't 

 demand a general exodus or . a wholesale mania of suicide on the part 

 of the insect pests when these men begin to study. And don't urge them 

 to throw dust in your eyes. They can do it all right enough— for a 

 while. They can talk Latin words and prophesy good news. But 

 guff is not the stuff we want. And sensible men know that results 

 worth while do not come in a day or even a month. They come from 

 long, persistent, thorough, scientifically honest study and work. 



Well, you can get just that for a few thousand dollars a year. Ade- 

 quate support by the State through legislative appropriation or 

 directly from some organization of fruit men — just as the sugar plant- 

 ers of Hawaii maintain their own special entomological investigating 

 bureau— for scientific investigation of the insect and fungous pests of 

 fruits is needed sorely. There is great, great need of more knowledge. 

 This knowledge can be got. How it can be got I have tried to tell you. 

 And that is all that I came up here from Stanford to say. 



Mr. Ehrhorn read the paper by Mr. E. K. Carnes on "Practical Work 

 in Combating the White Fly," as follows: 



PRACTICAL WORK IN COMBATING THE WHITE FLY. 



By E. K. CARNES, of San Fkancisco. 



The practical work against the white fly in this State, undertaken by 

 the State Commission of Horticulture, in so far as it has progressed, 

 up to the present time, may, for the purposes of this paper, be divided 

 into the three following stages: The work at Marysville, the work at 

 Bakersfield, and the preliminary work at Oroville. 



Upon the discovery that the white fly (Aleyrodes citri) had at last 

 made its appearance within the boundaries of this State, the citrus
