shown a nearer view of one of the trees. As the figure sliows, the 

 paper was carefully and closely a})j)lied to the tree, especially at the 

 top, and going around the tree twice made two thicknesses of the 

 paper, thus apparently eliminating all chances for the little borers to 

 get in. And yet some of the borers got in in spite of the tarred 

 paper bandage. 



We believe the tarred paper acted only as a mechanical barrier, 

 and that its odor did not add to its effectiveness. Hence we should 

 expect ordinary newspaper or any 

 other paper bandage to be equally 

 as effective a preventive if care- 

 fully applied. The tarred paper 

 did not injure our young trees in 

 in the least, although it was ap- 

 plied to the same trees for three 

 years in succession and remained 

 on the trees nearly the whole time. 

 But others (Smith, 1898) have in- 

 jured trees with it. Old news- 

 papers or any wrapping papers 

 are much cheaper, a little easier 

 to apply and probably just as ef- 

 fective, but they will not remain 

 intact nearly so long in northern 

 peach districts on account of rains 

 and winds. Smith (1898) records 

 some fairly successful experiments 

 with newspaper bandages ; and 

 Cord ley tells us that in Oregon 

 where the rains do not interfere 

 with it so much as in the East, it 

 is one of the most successful methods in use against the Pacific coast 

 peach-tree borer. Large or moderate sized trees were treated in New 

 Jersey with newspapers for less than one cent per tree. 



The evidence thus indicates that paper bandages, when carefully 

 applied, are one of the cheapest, and they are also quite an effective 

 method of kee]ung out peach-tree borers. Apply the paper closely
