some of the largest market gardeners in the country, and no case 

 of arsenical poisoning from eating cabbage treated in this way has 

 ever been reported. 



Other substances, such as alum, copperas and saltpetre, have 

 been recommended for use against this insect but are of no value. 



Recently a new treatment has been brought forward by the New 

 York Agricultural Experiment Station as being better than that 

 recommended above. The material used is known as the Resin-lime 

 mixture, and is prepared as follows : — 



Stock solution : — Pulverized resin, 5 lbs. 



Concentrated lye, ..... 1 lb. 



Fish or any cheap animal oil except tallow, 1 pint. 



Water, 5 gals. 



Flace the oil, resin and one gallon of hot water in an iron kettle ; 

 heat till the resin is softened, then carefully add the solution of 

 concentrated lye (prepared by the directions for making hard soap 

 always given on the can) ; stir the mixture and add the other four 

 gallons of water, hot; now boil till the mixture will unite with 

 cold water and make a clear, amber-colored liquid ; now add 

 water enough to make up five gallons. 



With this as a stock solution, to spray take : 



Resin lime prepared as above, ...... 1 gal. 



Water, 16 gals. 



Milk of lime 3 gals. 



Paris green, .......... 1-4 lb. 



Bring these together in the order in which they are named, add- 

 ing the Paris green last, stir thoroughly, and spray the plants. 

 Do not prepare the spraying solution mixture, however, till ready 

 to use it, as it settles on standing. 



This treatment has been used with good success, and with refer- 

 ence to it the following statements are made : First, that by it 

 late cabbage and cauliflower can be protected from the attacks of 

 the cabbage worm and cabbage looper by two sprayings. Second, 

 that in the case of cabbage the yield can be increased sixty per 

 cent to one hundred per cent. Third, that the cost per acre will 

 depend on the number of acres sprayed, the cost of spraying ten 

 acres twice being §20. Fourth, that the mixture must not be 

 applied to cabbage after the heads are two-thirds grown, nor to 

 cauliflower after the " flower" appears. Fifth, that only skilled 

 workmen should be permitted to spray cauliflower. 



In view of the amount of work necessary to prepare this mixture, 

 and the amount of care necessary, as indicated by these last two 

 statements, it becomes questionable whether the advantage gained
