Paris green be added to our fungicide and used all the time, on 

 everything we spray, we shall gain time and save labor. In other 

 words, spray for as many diseases and pests as possible every time 

 you spray. 



4. Bark Beetle. — These beetles love a sick tree. Early in 

 the spring they bore minute holes through the bark to the sap wood. 

 In these the eggs are laid, and when hatched, the grubs feed on the 

 sap wood. There are several broods in one season, and many 

 varieties of trees are affected. Healthy, vigorous tr6es are less 

 liable to attack than weaker ones. Some contend a healthy tree is 

 never attacked; but be that as it may, when trees of any kind are 

 badly infested, dig out and burn. 



5. Borers. — At Van Buren, in 1904, Mr. Harris stated that 

 be asked Mr. Scott what do you do about the borer? Mr. Scott re- 

 plied, I don't do anything about it. Once I think they killed a tree, 

 but I cultivated thoroughly, and they can not kill very many of 

 them. If you are all this fortunate, I need not dwell on this pest ; 

 but I am sure the peach tree borer has arrived. Still I do not see 

 how thorough cultivation helped the case here cited. 



No more beautiful moth can be found in our orchards than the 

 borer moth. The general color of both sexes is a deep steel blue. 

 In spring and summer, earlier, of course, as you go south, after 

 earth and forest and orchard have well warmed up, the female de- 

 posits her eggs in the bark near the roots, or higher up the trunk, 

 even in the bark of the larger limbs, according to the species — flat 

 heads in the trunk and limbs, round heads near the ground. 



These are only a few days in hatching. The larvae, now the 

 borers, penetrate the inner bark and sap wood, forming burrows. 

 Here they feed during the remainder of the season, doing great 

 damage. They remain dormant during the winter, form cocoons in 

 the spring, and finally issue forth as beautiful moths to repeat their 

 annual labors and die. There are at least two broods a year, and 

 some kinds may require more than one year for all their changes ; 

 but their busy days produce the same results. 



No amount of spraying will do any good. Many washes and 

 paints have been used to keep the moth from the trees. Some of 

 them may help, but there is danger of injury. Wooden or wire, or 

 even paper wrappers, left on from the preceding fall, placed there 

 for a protection from rabbits, or put on in the spring, will do much 

 good. But when the borer is actually in the tree, open a small 

 trench and dig him out ; or with rather flexible wire probe the bur- 

 row. This should be done in the early spring, as soon as you
