fields fire at certain times over-run with 

 great armies of thefe worms, as with the 

 other infects ; yet it is very happy that thefe 

 many plagues do not come all together. 

 For in thofe years when the locufts are 

 numerous, the caterpillars and grafs-worms 

 are not very conliderable, and it happens 

 fo with the latter kinds, fo that only one 

 of the three kinds comes at a time. Then 

 there are feveral years when they are very 

 fcarce. The grafs-worms have been ob- 

 ferved to fettle chiefly in a fat foil ; but as 

 foon as careful hufbandmen difcover 

 them, they draw narrow channels with al- 

 moft perpendicular fides quite round the 

 field in which the worms are fettled ; 

 then by creeping further they all fall into 

 the ditch, and cannot get out again. I 

 was allured by many perfons that thefe 

 three forts of infects followed each other 

 pretty clofely \ and that the locufts came 

 in the'firfl year, the caterpillars in the fe- 

 cond, and the grafs-worms in the laft : 

 I have likewife found by my own expe- 

 rience that this is partly true. 



Moths, or Tineoe, which eat the clothes, 

 are likewife abundant here. I have fecn.
