destroyed outer leaves, or even the healthy ones, would do good to the 

 crop by giving enough space for air and light and sunshine-warmth to 

 come round the plants and on the earth. 



Setting the loss, certainly caused by recurrence of attack, against 

 what wif/ht happen by lessening weight of root by removal of some 

 leafage, it may perhaps be thought desirable in the coming season to 

 experiment in this matter, taking care if the leaves are so infested as 

 to be useless that they shall be deslroi/ed at once, not merely thrown 

 aside. Where there is little maggot presence precaution may not be 

 needed, as rapid consumption by the cattle, use of salt, scalding the 

 troughs, or throwing quicklime where any heap of leaves might have 

 lain, would probably pet rid of any risk of infestation, or at least 

 of infestation to a serious extent, recurring from the transported 

 maggots.
