tion of preventives you do not reduce its number, but only drive it 

 away to unprotected orchards. A sufficient answer to this is, that 

 there should be no unprotected orchards, and that the peach-grower 

 who is too ignorant or indolent to employ the simple and inexpensive 

 means by which his trees may be protected, does not deserve that they 

 should give him remunerative crops.

Fig. 33.— Male and female moths of the peach tree borer, enlarged (after Emmons). 



[The male and female moths, which are quite unlike in appearance, 

 are shown in Figure 23, in twice their natural size, taken from Dr. Coquil- 

 let's " Our Injurious ^Egenans," in vol. v of the Journal of the Colum- 

 bus Horticultural Society. Figure 33, after Emmons, also illustrates 

 the same insects.] 



The treatment quoted above, of wood ashes and water placed in a 

 funnel-shaped cavity about the tree, would unquestionably serve a good 

 purpose in the destruction of the eggs and the young larvio, if applied 

 a few days after the deposit of the eggs or their hatching. But as the 

 period of egg-laying of the peach-tree moth extends over the months of 

 June, July, and August, it would require too frequent an application of 

 the ash remedy to render it reliable and practical. 



Carbolic Acid Wash. 



This wash has been tested for several years, and so far as we know, 

 has never failed to give satisfaction. Several large peach-growers 

 have used no other method of protection. Two or three formulas have 

 been given for it, but probabl}^ the best is that presented by Mr. Bate- 

 ham of Painesville, O., in the Country Gentlemaa, vol. xlv, 1880, p. 

 246, and also published, with others, in the Second Report oti the Insects 

 of New York, 1885, pp. 24-26: 



"For an orchard of five hundred bearing trees we bu}' a pint of 

 crude carbolic acid (or half as much of the refined), costing not over 

 twenty -five cents; then take a gallon of good soft soap and thin it with a 

 gallon of hot water, stirring in the acid, and letting it stand over night 

 or longer; then add eight gallons of cold soft water and stir. We
