are driven and buried. In the flying state there is no 

 efiectual method to destroy them. When a tlioht of 

 them in this state alight on a field, the country-people 

 assemble with rattles and other instruments, and by 

 making a great noise succeed in driving them away 

 for the time ; but it is only to take refuse in the neioh- 

 bouring fields. By these methods much of the vermin 

 was destroyed ; but there still remained immense quan- 

 tities, and their numbers daily increased from the adja- 

 cent countries ; for at the time when in New Russia 

 the Locusts had not yet attained the winged state, 

 legions of them made their appearance, coming, as is 

 supposed, from the Turkish provinces. Thus the inha- 

 bitants, who had been diligently labouring to cleanse 

 their lands of the insects by which they were already 

 desolated, were nowise relieved from them, seeins; as 

 they did their possessions infested by others from un- 

 known regions ; and all human means seemed unavail- 

 ing to avert the famine with which the provinces were 

 menaced."
