It is true that even under the most unfavorable circumstances each 

 fruit-grower may protect his trees from injury by careful observation 

 and methodical work, but by no amount of care and work can he pre- 

 vent his fruit from being spotted by scales carried to it by birds and 

 insects from near-by infested trees. 



Do not spray against paint. When trees to be sprayed stand near 

 painted buildings, these should be protected by a canvas while spraying 

 is being done. It is well to blanket horses used in the spraying opera- 

 tions, when a lime-sulphur solution is used. Persons preparing or ap- 

 plying the lime-sulphur spray should avoid getting it on the bare hands 

 or face, as it is very caustic. Leaky hose should be repaired at once. 

 See that all barrels and all apparatus are thoroly cleaned before using 

 the mixture in them, otherwise the nozzles are likely to clog. Thoroly 

 clean kettles, hose, barrels, pumps, nozzles, and all spraying apparatus 

 when the work is over for the season. 



Thoroly coat the trees, being careful to cover the smaller twigs 

 and branches and to get the mixture in all the forks and crevices. Spray 

 every part of each tree from two sides. If a heavy rain follows soon 

 after spraying, the treatment should be repeated.
