Po-nrdered TVlilte Hellebore. 



This is a finely-grcimd material, applied in the same manner as 

 the powdered tobacco, and what has been said in regard to that 

 material will apply eqnally well to the hellebore, which, however, 

 is not a fertilizer. In one of our experiments it was slightly more 

 effective than the tobacco. Hellebore has also been used in the 

 form of a decoction to kill the maggots, and will be again referred 

 to among the destructive measures. 



It has l)een claimed that dipping the plant into the powdered 

 hellebore just before setting will act as a protection, and this is 

 not unlikely. To do tliis most effectively, the plant should be first 

 dipped in water and then into the powder, that a complete coating 

 may be formed. This will not interfere with the groAvth oi the 

 plant, nor will it injure the roots. Professor Washburn has found 

 the dipping in the hellebore decoction of some benetit, but I believe 

 the dry powder dipping will be even more effective. 



Dry Lime. 



A handful of this material thrown around the cabbage plant a 

 day or two after setting, and applied frequently enough to keep 

 the surface covering complete, has been recommended. Personally 

 we have not had any experience Avith it, but as good results are 

 reported in other States, it is worthy of trial, both on cabbage and 

 along the rows in the case of onions and radishes. It acts in some- 

 what the same manner as the carbolized lime, but does not form a 

 crust. The important points here are keeping the covering com- 

 plete at all times and in close contact to the plants, so that the 

 maggots cannot slip down into the ground between the plants and 

 the lime. 



Bran and Glue. 



This mixture was reported as having been used successfully 

 agiainst the cabbage maggot in Minnesota by Prof. F. C. Wash- 

 bum. It consists of two pounds of glue, dissolved in one gallon 

 of water, and this mixed with one-half pound of bran. A handful 

 of the material is placed around each plant a day or two after
