results from this parasite work. At best it will be very very slow work 

 getting the parasite established so that they will be real factors in the 

 control of the Brown-tail, although we realize that it is the only means of 

 permanent control and are making every effort possible to get the para- 

 site established. 



Spraying. 



The work that is giving the most value at the present time in con- 

 trolling Brown-tail is that expended on the campaign for more spraying. 

 Our best instance is Kings County, where the first Brown-tail nest in the 

 Province was found eight years ago and which has been repeatedly infest- 

 ed since. But even yet we have not a serious or well established infesta- 

 tion in the whole county although we have had repeatedly small out- 

 breaks. According to Prof. Brittain's last census 87 per cent of the apple 

 trees in Kings County are sprayed. We have, therefore, carried on a 

 number of experiments to gain as full a knowledge of spraying in the An- 

 napolis Valley as possible, in order to demonstrate the value of spraying, 

 how to spray the most economically, etc. We have given this information 

 to the Brown- tail inspectors who are instructed to try to persuade all of 

 the owners of property on which Brown-tails occur to spray the following 

 spring. This campaign following the work of the Dominion Fruit In- 

 spectors and the very active and convincing campaign which has been 

 carried on by the United Fruit Companies for more and better spraying 

 is having the effect and this season saw more spraying than ever before 

 done in the Annapolis Valley. 



By this spraying campaign and by continuing the winter work in 

 collecting the nests we hope to keep the Brown-tails down, as they have 

 been kept down, so that they will not do one dollar's worth of damage in 

 the Province until we are able to get enough parasite introduced to hold 

 them in check without the winter collecting of the nests.
