The Codling moth also attacks the pear, and therefore the pear orchard 

 should also be sprayed in the same way as the apple for its destruction. 



The Bartlett pear is especially subject to produce knotty specimens, due to 

 the work of the curculio, and other insects. Indeed, fully half the crop has to 

 be thrown out for seconds on this account. But for two seasons now, I have 

 sprayed them carefully, and as a result, have had comparatively few knotty 

 pears. The editor of the Country Gentleman, in a recent number, gives his 

 experience in spraying Bartlett pears, and it corresponds with our own as given 

 above. We copy from that journal, outlines of two specimens, showing the 

 effect of the treatment as described above, but with us the disfigurement has 

 averaged greater than is here represented.

But the advantages of spraying for insect pests having been once proved, it 

 did not take long to find that it was of almost universal application. Our 

 Experiment Stations soon discovered the benefits of copper sulphate for 

 destroying fungi, and of kerosene emulsion for such insects as did not eat the 

 foliage but only sucked their nourishment from the leaves. These discoveries 

 are creating a revolution in fruit growing, and making possible the highest 

 success for those fruit growers who will use to the best advantage the prescribed 

 remedies. I will read a few lines on this point from bulletin No. loi, by 

 Prof. Bailey, of Cornell, on Spraying Trees. 



He says : Spraying is of some value every year, upon apples, pears, plums 

 and quinces. Nearly all the sprayed orchards are carrying a better foliage than 

 those which are untreated, and where the codling-moth, bud moth, case-bearer,
