ounces by measure of water. Spray only one tree with each, to 

 test effects on foHage. 



The ''Dreer Mixtures" were two small samples in a pasty con- 

 dition of lime and sulphur combinations with certain additions 

 to add to the effect. They were primarily intended for winter 

 application, but I decided to give them a summer test as a pre- 

 liminary. It was intended, should they prove satisfactorily effec- 

 tive, to put them on the market. 



It will be noted, also, that the amount of lime in the combina- 

 tion with the Potassium and Sodium is much reduced. This was 

 done to make spraying easier and clogging of the nozzles less 

 likely. 



Pursuant to these instruction, trees number 302 to 355 inclu- 

 sive were sprayed July 2nd, with the "Con-Sol" ; trees 200 to 

 249 inclusive were sprayed July ist, w'ith the Potassium and lime 

 combination ; trees 250 to 301 inclusive, were sprayed, July ist 

 and 2nd, with the Sodium sulphite and lime combination; trees 

 25 and 26 were sprayed, July ist, (as a test) and trees 356 to 

 376 inclusive July 4th, with the lime, soda and sulphur com- 

 bination ; trees 28 and 29 were sprayed July 2nd, with the Dreer 

 Mixture No. i, and tree 27 was sprayed with the Dreer Mixture 

 No. 2 July 2nd. 



Examinations were made of the treated trees July i6th and 

 30th and again August 13th. On the July examinations notes 

 were made on the individual trees in each series of tests, but no 

 further examinations were made. August 13th the following 

 points were looked to, under instructions : 



1. Make notes on each group of trees, as was done in the last series. 



2. Note the numbers of all trees that are very badly infested, and their 

 general character, i. e., whether very large, straggling, rough-barked, etc. 



3. Note the numbers of all trees that are very slightly infested and 

 their general characters as in No. 2. 



4. Note whether the sprayed trees as a whole are better than those 

 unsprayed, in color of foliage, etc. 



5. Note any apparent difference in color of foliage as between the dif- 

 ferent groups of applications. 



6. Spray any of the experiment trees that demand it, with the "Con- 

 Sol," 1 to 40. 



The general result was, that taking the orchard as a whole, it 

 had a yellowish, sickly appearance without apparent sections 

 indicating sprayed trees. On closer comparison the color of the 

 foliage was no better on the sprayed trees, while the leaves were
