such as just before the buds swell. This mixture will kill all scale 

 insects, and often kill the eggs of other things. It makes the bark 

 very clean and healthy. 



Mr. Irvine — What about spraying in the fall after the leaves 

 have fallen? 



Prof. Stedman — You will not reach anything like the per cent, 

 killed that you will at the time given. 



Prof. Irish — What about the use of caustic soda in preparing 

 this mixture? Seems like it w^ould be less work and not need boiling. 



Prof. Stedman — We are always looking out for cheaper, easier 

 methods for doing the work. Boiling is a nuisance unless you have 

 steam. Many, therefore, use the self -boiling mixture; 15 pounds 

 lime, 15 pounds sulphur and 15 pounds caustic soda are then used. 

 When the other ingredients are put with the slacking lime it will 

 boil. But you will not reach anything like the results you will with 

 the artificially boiled mixture as given first. Don't advise the use 

 of this latter. We absolutely cannot fight the scale with the dust 

 process. 



SPRAYING FOR BITTER ROT. 



In the absence of Mr. Faurot, Mr. Frank Horsfall, Assistant 

 Horticulturist from the Missouri Fruit Station, Mountain Grove, 

 was called upon to make some remarks on this subject. He said 

 he didn't have any data, but could state some of the facts concern- 

 ing the work done by Mr. Faurot this year, beginning wuth apple 

 scab, through till bitter rot season was past. They sprayed about 

 six times with the ordinary formula of Bordeaux mixture. The 

 same work was carried on by Prof. Scott, in Benton county, Ar- 

 kansas. For bitter rot alone, about three sprayings were neces- 

 sary. The results of this work will be issued in a bulletin, and any 

 one can get it who desires to do so. For the bitter rot, both Di- 

 rector Evans and Mr. Faurot advise to begin to spray as soon as 

 they see the first sign of it in the orchard. With us, this disease 

 generally comes first on trees set on low ground and thick headed 

 trees. Some varieties like the Willow Twig, Huntsman and some 

 others show this disease first, and we can see it there ; then spray 

 according to directions. 



Mr. Gano — How far north does the bitter rot extend? 



Secretary Goodman — Far as the Missouri river . 



President Dutcher — When can this bulletin be had ? 



Mr. Horsfall — It is in print now and will soon be ready. 



President Dutcher — I saw the exhibit made by Mr. Faurot at 

 the Fair. He said they would try the dust mixture next year.
