Bordeaux mixture is the most satisfactory. The first applica- 

 tion should be made early in July, followed by a second, after a 

 lapse of from ten days to three weeks, according to the weather. 

 Three or four applications should be made.

NOTES ON SPRAYING. 



W. M. Munson. 



The fact that insect and fungous enemies of the orchard may 

 be held in check by careful attention to spraying with certain 

 materials, has been so often and so plainly demonstrated that 

 further proof seems unnecessary. By our more progressive 

 farmers the practice is now looked upon as a necessity in suc- 

 cessful orchard management, and there are frequent requests for 

 information. To meet these inquiries, and to again call the 

 matter to the attention of others, a brief review of the subject 

 seems desirable at this time. Some points will be more fully 

 discussed in the annual report for the current year. 



Preparation for the Work: — If not already attended to, the 

 necessary pumps and nozzles should at once be secured; like- 

 wise the chemicals — except the lime for Bordeaux mixture, 

 which should be fresh when used. If a pump is already at hand 

 it should be examined and the packing of the valves should be 

 renewed. Be sure also that the hose is in good condition, as 

 otherwise much valuable time may be lost later in the season. 



It is advisable at this time also to prepare the necessary wagon 

 or cart for use when spraying. In lOw-headed orchards an 

 ordinary stone-boat or low wagon may serve the purpose well. 



What is the best pump? — There are so many good pumps on 

 the market at present it is not easy to give a specific answer to 

 the question. The "Eclipse" made by Morrill & Morley, Ben- 

 ton Arbor, Mich., is highly recommended by some, but person- 

 ally I have not used this form. The Field Force Pump Com-
