210 VEGETABLE FOES AND DISEASES 



However turning up and hand-picking is the most 

 certain process. Even forking the ground over at 

 intervals and collecting the chrysalids, or exposing 

 them on the surface to alternate cold and wet have a 

 good effect. 



3. Dress the ground with gas lime fresh from gas 

 works as soon .as the infested crop has been cleared 

 at the rate of 70 Ib. per rod, and leave on the surface 

 and spread evenly a month or six weeks before digging 

 or ploughing in. 



Remedies. i . Hand-picking is the surest method. 

 It is astonishing how large an area can be got over in 

 a day by a person with a will and nimble ringers 

 boldly taking the caterpillars one by one or, where 

 thick, twos and threes, between the ringers and crush- 

 ing them, having handy, say at each end of long rows, 

 a pail or can of water wherewith to cleanse the hand. 

 Chicken-hearted persons are no good for contending 

 against the Cabbage Moth caterpillars, being afraid 

 to handle and destroy what will assuredly ruin the 

 Cabbage crop if let alone. Some children will search 

 for and pick the caterpillars from between the folds 

 of the Cabbage leaves, promptly placing them in a 

 vessel containing a little paraffin oil, and under due 

 supervision the Cabbage crops may be well and rapidly 

 cleared at small expense. It is very important to 

 attend to the hand-picking when the caterpillars first 

 appear and before any serious harm is done (D), or 

 they will very soon render the Cabbages or Savoys 

 quite useless.
