PROCEEDINGS OF THIRTY-THIRD FRUIT-GROWERS ' CONVENTION. 163 



writing, from the State Commissioner, presented at any meeting of 

 the Board of Supervisors of his county. The appointment should 

 be made for a term of four years,, subject to the present provisions of 

 removal for cause. The compensation should be changed from a per 

 diem to a monthly salary. The salary should be regulated by the 

 extent or importance of the horticultural interests of each county and 

 incorporated in the county government act of any county appointing 

 such commissioner. The commissioner should have authority to appoint 

 such assistants as the demands of his department required. 



We are convinced that such a change in our horticultural law would 

 secure a much more efficient service than is possible under the present 

 system. 



Our horticultural interests far exceed those of any other state in the 

 Union, and surely an industry producing an annual income of more 

 than $60,000,000 should be entitled to the greatest possible protection. 



MR. MILLS. I move you that this paper be referred to a committee 

 composed of the chairman, Mr. S. A. Pease of San Bernardino, and 

 Mr. Cundiff, to draft a resolution along the lines therein set forth, the 

 committee to hand the resolution to the Committee on Resolutions, to be 

 presented to-night. 



The motion was duly seconded and carried. 



THE CHAIRMAN. The next paper on the program is a composite 

 one and has been contributed by the different Inspectors of Los 

 Angeles County. Each of these men is an expert in the matter he 

 handles, and all have had a wide experience in fighting scale and other 

 pests, and I have no doubt that this will prove one of the most valuable 

 of the papers presented this morning. Mr. Secretary, will you please 

 read the paper ? 



ORCHARD PESTS, AND THEIR TREATMENT. 



By the Los Angeles Inspectors. 

 RED AND YELLOW SCALES. 



All citrus fruit trees are subject to red scale infection. Lemon and 

 grapefruit, however, seem to be the ones most preferred by this scale 

 insect, and the lemon tree or orchard is usually the center of the red 

 scale infection of a district. We have no parasitic insects that in any 

 degree control this scale, and for this reason are obliged to depend upon 

 spraying or fumigation for control or eradication. In parasitical experi- 

 ence spraying has been proven a failure. The result of continued 

 spraying for successive years has been a gradual increase and spread 

 of the red scale infection. 



The hydrocyanic acid gas treatment has been the most successful.
