barrel sprayer, such as you see in the photograph, is perhaps 

 more used and better known than any other which can be 

 used for spraying. This particular apparatus is perhaps defec- 

 tive, however, in that it has no extension rod on the end of 

 the hose. That is a valuable appliance, and makes the appa- 

 ratus more effective. A very interesting form of apparatus is 

 that for use from a wagon. The apparatus is so arranged 

 that the man simply drives the horse along by the rows of 

 trees, and the spraying apparatus shoots the solution into the 

 trees as he passes along. In cases where there are very large 

 orchards to be sprayed that form is perhaps useful, but it 

 results in a very hasty spraying. It is better than nothing, 

 however. A more finished form of apparatus, and one which 

 is used to spray four rows of peaches, strawberries, or what- 

 ever is necessary to employ it on, consists of the ordinary barrel 

 form with four lines of hose mounted in the wagon, and con- 

 nected with gas-pipe connections, two stretching out on one 

 side and two on the other, so that, by driving along, four rows 

 can be showered at the same time. The principal cost of 

 the operation of such apparatus is in the labor. For such an 

 apparatus as that the labor costs probably two or three times 

 as much as in the simpler forms, but probably the work is 

 accomplished much quicker. If anything can be done 

 to cheapen the cost of the labor it would be a very good 

 apparatus. 



One of the best, and one of the most efficient forms of 

 apparatus for use on large orchard trees that I have seen, 

 consists of an apparatus which enables you to reach into the 

 tops of the big apple and other trees. On the sides of the 

 tank is built up a platform raised some five or six feet above 

 the ground, so that the man who is operating the spraying 

 nozzle stands some ten feet over the ground, and, with a 

 good long arm or ten foot extension, he can reach right out 

 into the tops, and throw the spray to good advantage. 



The President: "How do you spray for black -rot on 



grapes 



? " 



Professor Waite : "If the vineyard has not been sprayed 

 before it is usually best to spray before the buds flower. Some
