2l8 BOARD OF AGRICULTURE. [Jan., 



to the first part of September, especially through damp, muggy 

 weather, and for the length of time that the Bordeaux will 

 stick upon the leaves. Another method of spraying is by the 

 use of the barrel pump or cart spraying. That is where the 

 nozzles are stationary and attached to the back of the cart. 

 By the use of that apparatus you can spray four rows with 

 one or two nozzles for each row. This method only requires 

 one man to handle the sprayer and one man to drive the team. 

 Possibly one man could operate it if he had a steady horse, 

 but it usually requires one man to drive the team and another 

 to handle the sprayer at the same time. This is somewhat 

 like a power sprayer except that the horse does not furnish 

 the power. The man furnishes it with the pump, the pump 

 being the ordinary barrel pump. The objection to this style 

 of apparatus is the same as that urged against a power sprayer ; 

 that is, that we have the stationary nozzle, and the horse has 

 to go at a certain gait, and that is rather fast in order to get 

 good thorough spraying on the vines. Of course, with such 

 an apparatus, a good deal of the spray is bound to land upon 

 the ground rather than on the plants. In this method I find 

 it a decided advantage for a man to spray through in one 

 direction and then to go over it in the opposite direction of 

 the row, so that it takes in the two directions, and in that way 

 fully covers the foliage. The spraying can be done much 

 better. I find with all of the power sprayers it is very desirable 

 to spray twice. 



The third method is with the power pump sprayer, by 

 means of which the horse furnishes the power to the nozzles, 

 and in other respects the spray is applied as I have already 

 described. The objection to this is the lack of power in a 

 good many of the sprayers. The horse has to move too fast 

 to get good results, for unless the power is applied at about 

 the right point to the nozzle you do not always cover the 

 vines. I hope that the time will come when we can get a 

 power sprayer that will be satisfactory in all respects, but as 

 yet I have not seen a perfect one. They are all more or less 

 unsatisfactory. Where a man has a large acreage he may 

 be compelled to use these imperfect machines. I am hoping 

 that I may be able to eventually find one machine that I think 

 much better than the others, and which can be generally used 

 for this purpose, and thus get rid of the disadvantages of the
