the best preventives. Destroy all infested plants, 

 being sure to get the maggots when pulling them 

 up. The remaining plants should be treated with a 

 gill of strong caustic lime water, or solution of 

 muriate of potash poured about the root of each 

 plant, first removing an inch or so of earth. In place 

 of these solutions carbolic acid emulsion is some- 

 times used ; or eight to ten drops of bisulphide of 

 carbon are dropped into a hole made near the roots 

 with the dibber and then covered in. Extra stimu- 

 lation, as directed for Club-root, will help carry the 

 plants through. 



Squash-bug: — This is the large, black, flat "stink-

 be trapped under boards and by early vines. The 

 young bugs, or "sap-sucking nymphs," are the ones 

 that do the real damage. Heavy tobacco dusting, 

 or kerosene emulsion will kill them. 



White-fly: — This is the most troublesome under 

 glass, where it is controlled by fumigation, but occa-

 cucumber vines. The young are scab-like insects 

 and do the real damage. Spray with kerosene emul-
