practically coated with the fungicide when the rain comes, 

 because when the rain comes the fungus comes and the infec- 

 tion occurs, it does not occur afterwards. Don't delay by 

 waiting- if you think it will wash off, but just spray thor- 

 oughly before the rain with lime-sulphur, and if you believe 

 it conies off easil\-, undertake the job of washing it oft'. 



J\1r. Staples : May I ask the question if the leaves are 

 to be burned in the spring, how early can that be done, or 

 how late; that is, after the leaves are prettv drv in the spring? 

 \\ ill it do to burii them when fire would run in the g^rass and 

 leaves? 



Prof. Whetzel: The time you can burn them must 

 depend upon the buds. I should say to be on the safe side 

 they could be burned before the buds open. If they are dry 

 before that time, all right. 



Dr. Britton : I would like to ask if he has tried other 

 insecticides with lime-sulphur? 



Prof. Whetzel: I think he did, Dr. Britton, but I 

 don't recall what they were. I think he tried arsenite of 

 lime, but I don't recall the results just at the present time. 

 We have tried quite a number of insecticides besides the 

 arsenate of lead, but they are of doubtful value. 



Mr. Curtiss : W' hat are the respective advantages of 

 the lime-sulphur preparations, the self-boiled and the home- 

 boiled? 



Prof. Whetzel: Self-boiled is Scott's so-called self- 

 boiled. I am very sorry that Scott named that "self- 

 boiled" ; it is not boiled at all, but the self-boiled is what Scott 

 has developed for spraying peaches, summer spraying- for 

 peaches. That is quite dift'erent from home-boiled concen- 

 trate, which is to all intents and ]xirposes just like the com- 

 mercial. \\'e carried along side by side in our spraying experi- 

 ments the commercial lime-sulphur clear, commercial with 

 sediment in it, home-boiled clear and home-boiled with sedi- 

 ment in it, and Mr. Wallace carried along in a good many 

 cases, Scott's self-boiled. I think all the experiments taken
