really to capture the odd trees around the country ; now, un- 

 fortunately, we have something that is looking after the odd 

 trees — the San Jose scale. The growers who have large or- 

 chards will look out for their trees ; it is the scattering trees 

 and the small growers that cause the trouble. I an.i not sure 

 whether I would care for the law now or not. 



Question Xo. 24 : Has anyone ever whitewashed peach 

 trees in a commercial way to retard the trees starting in the 

 spring ? 



Prof. Hedrick : Whitewashing to retard the buds in 

 spring is not practised in ^Michigan or New York, so far as I 

 know. I believe Professor Whitton carried on an experiment 

 which proved that whitewashing would retard the trees some- 

 what, and this practice has quite a following in the commercial 

 orchards of Missouri, but so far as I know in the East and 

 North, the trees are not whitewashed. The application of 

 Bordeaux mixture, and lime and sulphur put on the peach or- 

 chards in the Northern States have a retarding effect vipon the 

 peach buds. Whether that effect amounts to much is more 

 than I can say. 



Question No. 28 : What is the outlook for the complete 

 control of the San Jose scale ? 



Dr. W. E. Brixton : I hardly know how to answer this 

 question. I think you will remember when Professor Smith 

 was here he told you he didn't look for any immediate result 

 in the scale working itself out, as many people think it will in 

 time. He said he should look for it to be about as destructive 

 for the next twenty years as at the present time. The scale 

 has probably been in this State about twenty years. The his- 

 tory of these pests is that they are somewhat worse at first 

 and finally become less destructive. There are several reasons 

 for this. The first is that their natural enemies hold them in 

 check, and another is that the the plants upon wdiich they 

 work seem to take on a sort of immunity after the\- have been 

 attacked year after year. Our trouble comes from the odd 

 trees all over the country, which are completely infested b\- 

 the scale. If these trees could be killed outright, never to 

 grow again, the question would settle itself.
