otherwise, concerning the dates when we would do pruning- 

 and spraying in those orchards. The pubhc was invited and 

 attended. On the appointed days the demonstrators in charge 

 of the orchards were present, pruning trees according to ap- 

 proved and proper methods, and speaking of the principles of 

 pruning- as illustrated by the work done, talking and working 

 at the same time, and also doing the spraying, making in the 

 presence of the visitors the lime-sulphur wash, — best known 

 material to control the San Jose Scale, which was the chief 

 pest for which these demonstrations were given. However, 

 the Codling Moth is an important enemy of the pome fruits, 

 or apples, pears and quinces, and to show how this was to be 

 controlled we gave subsequent demonstrations in the same 

 orchards, just after the falling of the blossoms, spraying with 

 two pounds of arsenate of lead in the 3-4 formula of Bordeaux 

 mixture. Visitors were again present to see the work done, 

 listening to the remarks and directions regarding the Codling 

 Moth spraying, asked questions, and went home and treate.l 

 their own trees likewise. 



In the fall of the year we again met in the Demonstra- 

 tion Orchards and studied results. In most orchards it was 

 to be seen that that portion which we had taken for demonstra- 

 tion purposes had considerable more fruit than the other por- 

 tions not so treated, and at the same time was less infested by 

 Scale. The remarkable results of the Codling Moth spray- 

 ing were that in some orchards 98 per cent, of the apples were 

 found free from infestation by this pest, while on trees not 

 treated the reverse was to be found true, or almost every fruit 

 wormy. This was conspicuously to be observed in many of 

 the orchards that were carefully examined by hundreds of 

 persons visiting them, ft was plainly to be seen that the 

 Codling Moth spray had not only destroyed the pests making 

 the wormy fruit, but had also kept the fruit on the trees longer 

 and had resulted in a greater quantity of fruit that was per- 

 fect and sound. Thus, this spraying alone had fully justi- 

 fied all the expense and efifort of the Demonstration Orchards, 



However, as the San Jose Scale is at present the arch foe 

 of the fruit grower in Pennsylvania, as in almost every State,
