THIRTY-FOURTH FRUIT-GRO^T^RS ^ CONVENTION.

only during the last five years. I have found with small doses I could 

 not kill the scale, so I kept increasing the doses until we have had some 

 degree of success. In killing red scale, we used double the amount of 

 cyanide and acid that we do on the black scale. On a tree eleven to 

 fourteen feet high, for the black scale dose, I should use in the neighbor- 

 hood of nine ounces of cyanide, and for a red scale tree I would put on 

 eighteen ounces of cyanide. But, of course, we don't know to an exact 

 nicety the number of cubic feet. We never have measured our trees. 

 We have been working under the county's supervision, and the county 

 dosage runs from one and a half to double the amount of the ordinary 

 dosage used by contractors, and I think that is the reason why we have 

 gotten better results. 



MR. :\IASKEAV. Ladies and Gentlemen : There has been great diffi- 

 culty in the past in accomplishing satisfactory results in Orange County. 

 Mr. Camfield has been associated with that work, and he can bring out 

 the difficulties they have met there. 



MR. CAAIFIELD. The dosage that has been applied in Orange 

 County is as heavy as has been applied anywhere in exterminating or 

 trying to exterminate the purple and red scale. We first tried a double 

 dose, gave them all they would stand in one charge, and then in 30 min- 

 utes put another charge in. We found we were not getting results in 

 that way. We found that the one heavy dosage would do the same work 

 l)y leaving the tents on an hour ; and I also found where the work was 

 done under my supervision by the county tents, applying a big dosage, 

 we were getting better results than from private fumigators. On in- 

 vestigating the private fumigator's work, I found that where there was 

 more than one private fumigator in the district, they had to compete 

 with the others, and in order to get the work, had to do it cheaper and 

 buy less material and put less on. In some cases, the grower could buy 

 the material, but he didn't know whether it was put on or whether it 

 was stolen in the night. That was the trouble years ago in Orange 

 County, I am sorry to say, where they were competing for the work so 

 closely and keenly. They had to do it for almost nothing in order to get 

 the work, consequently there was no good work done. 



In resurrecting the fumigation question three years ago — it was all 

 spraying up to that time — we had the worst name in the State, and it 

 came right from Sacramento. Complaints went to Sacramento that 

 Orange County was the hardest county in the State, the "buggiest" 

 county. This was a hard one on us. I went immediately to work to 

 resurrect the fumigators. but they Avere dead. They said they were out 

 of business. They couldn't compete with the spray pumps. The only 

 salvation for the commissioners then was to go around and buy up the 

 tents, if we could, and put in good fumigators and start anew. The 

 consequence is, that in two years' time we have got the spray pumps 

 l)ractically out of the way — all sold or hid in the barns, or run off and 

 dumped into the sloughs down there. And this year there has been 

 over 250,000 trees fumigated. We are getting clean fruit and good 

 prices. I think that the heaviest doses we have given are the only ones
