New York, Delaware and other states show that its 

 injuries may be prevented to a great extent by spray- 

 ing with Bordeaux mixture to which rosin soap has 

 been added to make it adhere better. Professor F. D. 

 Chester's recommendations are as follows : "Dissolve 

 2 pounds of the rosin soap in the necessary quantity 

 of water and add to the Bordeaux mixture, which is 

 prepared in the ordinary way. The first application 

 in this section should be made about the middle of 

 July and repeated about two weeks later. The eco-

nomical spraying of asparagus demands a specially 

 devised spraying outfit, and should consist of a cart 

 with wheels sufficiently high so that the axles will 

 brush only the tops of the plants. On this cart is 

 mounted a barrel and a pump, the latter being con- 

 nected with a length of pipe running along the back 

 of the cart and parallel to the axles. To this horizon- 

 tal pipe are attached three tees and short nipples, to 

 which are attached the nozzles. By driving across a 

 field in the direction of the rows a rather broad strip 

 of plants can be sprayed as rapidly as it takes a horse 

 to slowly pace the ground.
