 Hon. Charles A. Wilting, 



Commissioner of Agriculture^ Albany: 



Sir: — I am transmitting to you herewith the first installment of the 

 reports of our cooperative experiment work for the season of 1905. This 

 bulletin comprises a discussion of cooperative experiments in spraying 

 against the plum and quince curculios, in which it appears that on cher- 

 ries the curculio can be kept in check by spraying, that there is a prob- 

 ability that it can be controlled to some extent on plums and also that 

 there is reason to hope that spraying will aid in controlling the quince 

 curculio ; the result of experiments in spraying for the grape root-worm 

 in which it is shown that this method of fighting this pernicious insect 

 is very effective ; and also an account of the preparation of Bordeaux 

 mixture with the prepared limes. 



Respectfully submitted, 



L. H. Bailey, 



Director.
