does not get good results with even a pound of Paris green 

 to fifty gallons of water. I live in New York state, where the 

 state law makes it good, and the analysis of the Paris green in 

 New York state has shown a very uniform product. Good 

 spraying apparatus then, and an effective insecticide, either 

 lime and sulphur, or some of the other things, are the two nec- 

 essary things for spraying. The most important thing is 

 thorough work ; I can't say thorough work enough times, or 

 say it hard enough. I have seen some horrible jobs of spray- 

 ing, and I know the San Jose scale is so small that you have 

 got to hit every pin point on the tree. You can't do it too 

 thoroughly, and I think nine-tenths of the adverse reports are 

 right on that point — they don't do it thoroughly enough. You 

 have got to have a pretty well trained hired man that you can 

 send out and spray, if you do a good job. I have come to the 

 conclusion myself that when an orchard is very badly infested, 

 it is almost impossible to get that scale under control with one 

 spraying. I am quite in favor of one spraying in the fall 

 for several reasons. One is you get all the young scale. The 

 scale continue to hatch until December, and you kill all the 

 young scale just hatching, and you kill those that are about 

 ready to go into winter quarters, and you stop the breeding in 

 the fall, and oftentimes there is generally more time to spray 

 in the fall than in March. I am a thorough believer in one 

 spraying in the fall. Then again in March. If you kill 95 per 

 cent, in the fall, it is a very good job, but there is five per 

 cent. left. So I believe in one application in the fall ; then 

 follow this with one application in the spring — say in March. 

 It has been done in the summer, when the foliage is on, but 

 all you kill is the young scale. 



(The speaker then show'ed a number of lantern slides, illus- 

 trating the scale and methods for controlling it, concluding a 

 very enjoyable and profitable lecture.) 



Discussion. 



A Member : What do you think of spraying with lime 

 salt and sulphur this time of the year ? 



Prof. Slingerland: I think it is all right. I have had sev- 

 eral questions asked me. and one of them is, have you got the
