580 ANNUAL REPORT OF THE Off. Doc. 



PROF. MARLATT: :\Jv owu experience has been that lye washes 

 are not effective. 



DR. FUNK: I think there is a great difference with reference 

 to the length of time in boiling the ingredients. As I understand 

 the I'rofe.^sor he slakes his lime first and tlien adds his sulphur 

 and then builds his fire. I boil an hour and a half but I boil effect- 

 ually all that time. I have a seventy-five gallon kettle and I have 

 it on a natural boil all the time and I will put in fifty pounds 

 of lime, the best fresh burnt lime that I can get, the Cedar Hollow 

 lime, and liave a man stirring, and while I have the best heat 

 I apply my sulphur and it never checks the boiling and I keep that 

 boiling up from one hour to an hour and a quarter and apply my 

 salt and keep it boiling for another half hour, so that there is not 

 much difference because I have a solid boil all the time. 



COL. DEMMING: I was about to ask the gentleman whether he 

 had ever tried as a remedy diluted cadmium nitrate? 



PROF. MARLATT: I have had no experience in that direction. 



COL. DEMMING: When the San Jos6 Scale first appeared I 

 tried that and found it was most destructive and also destructive 

 to every specie of insect from the smallest specimen up. I also 

 found, after experimenting several days with the San Jos^ Scale, I 

 could feel them running over me and I wondered if there was any 

 one here who has had that experience, because I believe they 

 can be carried from one place to another very easily. I desire to 

 say that I felt the sensation on my hand, and on examining it with 

 a powerful lens I found some there. 



PROF. SURFACE: I read from the November Bulletin, page 17, 

 with reference to one way in which they are disseminated: "Work- 

 men themselves are very likely to carry the young pests upon their 

 clothing." 



PROF. ATWOOD: I have had some experience with this lime, 

 sulphur and salt wash and have burnt myself and done all kinds of 

 injury, and one point that I wish to bring out is that, at the time 

 the lime, sulphur and salt are boiling, they change color and when 

 you procure the amber color you have accom})lished the boiling you 

 wish and sometimes you can secure that color in half an hour's 

 boiling. Nearly everything d('p(nHls on the character of the lime. 

 T would use the finest sulphur T had opportunity to obtain, even 

 if I had to pay an extra thirty per cent, more for it. Be sure that 

 the lime is good; that is a very important consideration. I would 

 like to speak of the way in which we i)repare it in our State: We 

 regard salt of. not much importance, little bit perhaps, because it
