EXPEEIMENT STATION" EEPOET. 617 



The last sentence of the record determined the application of 

 ^'Textil Oil," and on Saturday, March 4th, Mr. E. L. Dickerson 

 treated one side of the tree with an atomizer, using one part in twenty 

 of water and seeking to give to all the infested growths a careful dose 

 of the spray. The wind being liigh on March 4th, only one side of the 

 tree was sprayed. March 6th, the rest of the tree was sprayed in the 

 same proportion, but with a compressed air sprayer, through a Yer- 

 morel nozzle. The entire tree was, in fact, sprayed at this time, but 

 the heavier application was made from the side which had not been 

 reached on the 4th. The result was, a tree so clean that up to the end 

 of August not a live scale was seen on it. There was no appreciable 

 injury to the fruit buds and certainly none to the tree. Only two 

 fruits reached maturity, but that has been, practically, the record of 

 past years as well, and there was bloom sufficient for a full enough 

 set had it made properly. 



Of course this application is not so conclusive as it would have 

 been had there been no "Kill-O-Scale" applied in October, for it is 

 impossible to say definitely how much good that did. That it was 

 very effective the record shows; that I considered winter spraying 

 necessary at the ISTovember examination is also shown. Practically, 

 there was a double application of soluble petroleum, with results that 

 were as nearly perfect as could be reasonably expected. "Textil Oil" 

 carries more petroleum than '"Kill-o-Scale," forms a milky emulsion 

 with water and sprays perfectly. 



Kill-O-Soale. 



The report for 1904 contains, on pages 646 and 647, a brief refer- 

 ence to this material and the results that had been obtained from 

 its use up to that time. The conclusion then recorded was : "Cer- 

 tainly we have come nearer to a preparation of petroleum which may 

 be diluted with water, and it offers the best chance of a satisfactory 

 effect of any of the preparations now on the market, though at 

 a somewhat unreasonably high cost." 



The conviction expressed in this paragraph has been verified in every 

 particular. Partly by purchase and partly by the courtesy of the 

 Griffith & Turner Company, of Baltimore, Md., material was 

 secured for use in the Experiment Orchard, on the Marsh orchard, the 

 Howell orchard, the Dickerson orchard and the Barton orchards. The
