THIRTY-FOURTH FRUIT-GROM'ERS ' CONVENTION.

Examinations have shown that it has not taken hold. However, there 

 may be conditions that cause that. The right conditions may not have 

 existed when we put them out. The way to do is to follow that up. 

 We have another shipment of the same material now at San Francisco, 

 and are going to restock the orchards again. We went do^^oi there 

 into a district where it didn't make much difference whether they 

 fumigated or not. We tried to get them into an orchard that was 

 abandoned, as a test place, to give them a trial, and if they succeeded, 

 then it would be time to trust to that parasite. But, in the mean time, 

 we can't wait for parasites until we have taken them to a place and 

 given them a good trial. 



ME. ]\IILLS. What success have you had with the parasites that you 

 have taken to San Diego? 



MR. CARNES. At the last examination we were unable to find any 

 work to amount to anything. The parasite that came in from China 

 looked better than any one I had seen. Mr. Cundiff saw it, as did a 

 great many other gentlemen. I think Mr. Allen saw it. It w^as a big, 

 robust parasite, and we saw them ovipositing in the scale. Of course 

 they are liable to pass from tree to tree and they may show up later. 

 Then climatic conditions make some difference. There may be condi- 

 tions at the time of placing them in the orchard that they have to over- 

 come. The work of introducing them in the past has not been as 

 successful as we would like to see. It is very hard to get a sufficient 

 start. Instead of sending one shipment in and trusting to that to do the 

 work, we should follow up those shipments, and try it over and over 

 again. 



MR. ]\IILLS. You have some parasites for the red scale? 



]MR. CARNES. We have never had very many for the red scale. 

 This one comes from the north of China, which place seems to be the 

 home of the red scale. It seems to be a big, robust fellow. It is a new 

 thing, and we can not tell yet what it will do. 



j\IR. MILLS. Has the shipment been sufficient to try it thoroughly? 



]\IR. CARNES. The work has been largely experimental. At San 

 Francisco, in addition to our regular quarantine, and just before the 

 earthquake, we had considerable of this stock. The earthquake 

 destroyed practically all of our parasites. We have not had a fair 

 trial on it. The earthquake destroyed our stock, and we had to start 

 over again. We have never had a suitable place to propagate parasites. 



MR. MILLS. Tell us about the insectary, will you, Mr. Carnes ? 



PROFESSOR COOK. I don't believe, Mr. President, we had better 

 bring that in now. I don't think we had better bring in another sub- 

 ject that is entirely different. 



MR. MILLS. All right.
