240 FRUIT CULTURE. 



Every one caught reduces the 

 number of eggs. Chickens and 

 turkeys if allowed to remain in 

 the cabbage lot will devour many 

 of the worms. 



These worms soon form into 

 chrysalids to emerge as butterflies CABBAGE worm. 



to lay eggs for a second crop of »• Larva; b. Chrysalis, 



worms. This second crop can be avoided by putting boards, setting 

 them on edge, between the rows, and the worms will attach themselves 

 to the boards and turn into chrysalids. These can then be gathered and 

 destroyed. 



THE LATEST INSECT DESTROYERS. 



Bordeaux Mixture. This is the celebrated mixture which is com- 

 ing into general use among fruit growers : 



6 pounds Copper Sulphate. 

 4 pounds Quicklime. 

 40-50 gallons Water. 



Dissolve the copper sulphate by putting it in a bag of coarse cloth and 

 hanging this in a vessel holding at least four gallons, so that it is just 

 covered by the water. Use an earthen or wooden VESSEL. Slack the 

 lime in an equal amount of water. Then mix the two and add enough 

 water to make forty gallons. It is then ready for immediate use but will 

 keep indefinite!}'. If the mixture is to be used on peach foliage it is ad- 

 visable to add an extra pound of lime to the above formula. When ap- 

 plied to such plants as carnations or cabbages it will adhere better if 

 about a pound of hard soap be dissolved in hot water and added to the 

 mixture. For rots, moulds, mildews, and all fungus diseases. 



Amtnoniacal Copper Carbonate. This is used for the same 

 purpose as the Bordeaux mixture. 



*1 ounce Copper Carbonate. 



Ammonia Carbonate enough to dissolve the copper, 



9 gallons Water. 



The copper sui,phate is best dissolved in large bottles, where it will 

 keep indefinitely, and it should be diluted with water as required. 



I/Ondon Purple. This is used in the same proportion as Paris 

 green, but as it is more caustic it should be applied with two or three
