potassium sulphide is helpful. When Hollyhocks 

 and Onions are badly attacked, the sacrifice of the 

 crop and its destruction by fire may be the only 

 methods open. In the case of hetercecious species 

 it is requisite to break the Xfe cycle by removing 

 one of the known host plants. (For further par- 

 ticulars, see CHRYSANTHEMUM, CARNATION, and 

 HOLLYHOCK.)

yellow clay is rammed in with heavy wooden 

 rammers, and the operation is commonly known 

 as puddling. When water sluices are inserted it 

 is necessary to "puddle" for at least 3' out, to 

 prevent leakage. 



Sometimes the term "puddling" is applied to 

 the dipping of Cabbage plants and other Brassicas 

 into a puddle of lime, soot, and earth, mixed up 

 into a thin paste with water. This is a capital 

 plan in cases of drought and where attacks of 

 gall weevil and club are feared.
