122 — How to Make the Garden Pay. 



150 gallons of water, now seem to give little inconvenience to 

 beetles and slugs. I have been gradually increasing the propor- 

 tion of the poison, and at present use one pound to only 50 gal- 

 lons of water. But in order to make this entirely safe, and to 

 head off every chance of injury to the foliage, I either combine 

 the Bordeaux mixture (spoken of in next chapter) with the Paris 

 green, thus fighting blights as well as insects by one application, 

 or at least add milk of lime freshly made by slacking two or 

 three pounds of burnt lime, to the 50 gallons of Paris green 

 water. Always mix the Paris green with a little water to a paste 

 before you add it to the spraying liquid. 



Potato beetles are very destructive to egg plants, especially 

 when first set out, and then again late in the season, after pota- 

 toes have matured, and the beetles find no more food except the 

 egg plants, of which they are very fond. The young plants, when 

 first set out, then still tender and checked in their growth, would 

 fall easy victims to the beetles. They should be closely watched, 

 and the beetles picked off by hand two or three times a day, un- 

 til the supply seems to be exhausted or engaged elsewhere. 

 Afterwards the larvae that may hatch from the few eggs de- 

 posited on the plants notwithstanding all our efforts, can easily 

 be kept off by Paris green application. A similar treatment is 

 advisable for potato seedlings, or choice early potatoes of any 

 kind. I have seen beetles come on in such numbers, after the 

 potato season in New Jersey, that no matter how many might 

 die from the effects of the poison put on egg plants, their places 

 were at once filled by others, and it was impossible to save the 

 plants from entire annihilation. 



Radish Fly and Maggot. — I might rest contented by 

 simply referring to my remarks under the heading of Onion 



Fly. Let me say, how- 

 ever, that entomologists 

 classify the radish fly and 

 maggot as antJwmyia 

 brassiccs, and give us 

 three species of onion fly 

 or maggot, namely, the 

 imported onion fly {an- 

 thomyia ceparuni), the 

 native onion fly {Ortalis 

 arcuatd), and the black 

 onion fly {Ortalis flexd).
