Ordinary soajy and lohale oil soaj) (p. 223), even two applicatioriS, 

 offered little or no protection. The addition of Paris green to a 

 soap wash will not increase its effectiveness, and it may injure the 

 trees. Carholic acid soajys or the Shaker wash (p. 224) would afford 

 no more protection than ordinary soaps, we think. 



Whitewash or whiteioash and linseed oil lo ashes (p. 225) were 

 wholly ineffectual in our expernnents. AVe doubt if whitewash 

 and ghte, or Bordeaux inixture have better preventive qualities. 



By making two applications the same season of HaWs celebrated 

 loash (p. 225) we succeeded in keeping out from one-third to one- 

 half of the borers. This wash will not remain intact long enough 

 in Xew York State, hence it is of little value unless applied twice, 

 which makes it too expensive a process. We cannot see how Sted- 

 nian^s (p. 226) or other variations of Hale's wash could afford any 

 greater protection from the borers. 



Two applications the same season of a lime, salt and sulphur 

 wash (p. 227) and a resin tcash (p. 227) gave little encouraging 

 results to peach-growers. 



A Paris green and glue wash (p. 228) killed our trees in a few 

 weeks. 



White paint (p. 228) proves to be quite an effective wash, keep- 

 ing out from one-half to live-sixths of the borers, but it may injure 

 young trees, and we doubt its proving as effectual on old trees. 



White paint and Paris green or green paint (p. 229) is quite an 

 effectual wash but it seriously injured our young trees, and is there- 

 fore hot to be generally recommended. 



The Hydraulic cement wash (p. 230) which has recently attracted 

 considerable attention, makes an ideal coating over the bark, but we 

 did not succeed in keeping out any borers with it, thus shattering 

 another theoretical ideal. 



Printer'^s inh (p. 231), although it apparently kept out nearly 

 one-half of the borers, injured our trees, and thus cannot be 

 recommended. 



Raupenleini (p. 232) dendrolene (p. 232), kept out all of the bor- 

 ers, but killed all the trees. See figure 56. 



Pine tar (p. 234) kept but a few borers out of our trees. 



Gas tar (p. 235) proved to be the best application we tested. We
