day live scale was found only near the tips of the twigs next to 

 the fence, obviously due to imperfect spraying. The leaves 

 were quite a little burnt in places, though iTot to any serious 

 extent. October 25th, most of the leaves were off, and what 

 remained werei spotted. 



November 2d, an the final exaimination, the Kill-O-'Scaile 

 seemed to have been quite effecti\'e. It left an oily appearance 

 oil the twig's, and seemed tO' have cleaned up the scale pretty 

 well. There is quite a heavy set of fruit buds, and, while the 

 oil has caused some discoloration on the outside coivering, mO'St 

 of the buds wdien cut into appeared to be sound. The applica- 

 tion on this tree was excessive, and appearances indicate that 

 some care is required in a|)|Dlying this mixture when the buds 

 are forming. The foliage was not yet all off. and what re- 

 mained was not abnormally spotted. Where the scales were 

 thickest the oil seemed to^ have been most effective, though even 

 those half-groiwn black forms well out on the branches and 

 close to the buds, which ordinarily form the hiljernating corps, 

 seem tO' be pretty generally dead. 



Tree 8 — 'Grimes' Golden Pippin. March loth, this tree was 

 found to be very badly infested and, to give it the best possible 

 test, I drenched wdth the "Universal Insecticide and Scale 

 Killer." When dry, the tree was evenly bluish white to the very 

 tips, showing work as nearly perfidct as can be reasonably 

 expected. 



April 26th, the tree had made a start, and it was apparent 

 that there would be considerable dead wood. May 8th. the 

 first blossom opened, and May nth was in full bloom, indicat- 

 ing a set of fruit much greater than the tree could possibly bear. 

 Petals did not begin to drop until after May 17th, and between 

 that time and the 8tli of June, I cut out considerable dead and 

 dying wood. At the latter date, there was a heavy set of fruit ; 

 the cutting out had given a ragged irregular appearance and 

 new shoots w-ere making from the center. There was yet 

 plenty of li\-e scale, and I conld not find that there had been any 

 material benefit from, the IMarch application of Scale Killer. 



June i8th. the lower branches w^ere sprayed with ciustic soda 

 at the rate of f pound dissolved in 8 gallons of water, simply 

 to determine what effect the material would have on the foliage. 

 Next day the leaves were distinctly spotted and burnt at the 

 edges, and the soft, new shoots were also spotted. June 27th, 

 the tree looked bad; the foliage was thin, yellowish., the wood 

 brittle, with a tendency to break at points where the scale was
