way that the inhabitants of some southern countries 
have been constrained to feed upon locusts themselves,, 
after these had eaten up all their other provisions, _ 
Where these numerous tribes of animals are bred 
and collected, as has been already said, is not certain- 
ly known. Linneus says they are produced among 
the Norwegian and Lapland Alps; and Pontoppidan 
supposes that Kolin’s rock, which divides Nordland 
from Sweden, is their native place, But wherever 
they come from, none return. Their course is pre- 
destinated ; and they pursue their fate. 
Such is the best account that can as yet be obtain- 
ed of this singular animal: Probably, as its natural 
history comes to be better known, some abatement 
may be made from the marvellous part of it. Though, 
as it attracted the attention of the great Linnzus, we 
must rest satisfied that the leading traits of this ac- 
count are just. 
* * It is proposed, in the course of this work, to 
give, from time to time, accounts of the most re- 
markable objects that occur in the walk of natural 
history, accompanied with figures of such as are, 
uncommon, executed by that ingenious artist, Bewick 
of Newcastle.
