are driven and buried. In the flying state there is no 
effectual method to destroy them. When a flight 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 refuge in the neigh- 
bouring fields. By these methods mueh 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, seeing 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.” :
