meet with over 800 surface grubs in three rows of roots, and 
equally impossible would it be to meet with bald, rounded 
patches in our meadows, from which to extract over thirty fat 
larva of the cockchafer in the space of a square foot. 
We think, then, that the primary cause of fairy rings is the 
destruction of circular patches of grass, and not the construc- 
tion of rings in the first instance either by moles or electricity, 
and that these rings are subsequently occupied by fungi
