Observations on the various Insects 
Oil and soap-suds will kill them. Greasy manures, soot, and 
lime, would assist in hanishing them. 
Water poured into their burrows with a few drops of oil will 
destroy them. 
Garden-pots buried in their runs, with 30 drops of oil of tur- 
pentine in each, and covered over with boards, are excellent traps. 
Fresh turves ivatered every night will decoy them to retreat 
under them. 
Hundreds of thousands are caught at Berlin annually, by sinking 
Jlotcer-pots 2 inches below the surface. 
In June and July the eggs are easily destroyed by digging up 
the nests. 
Boiling water, urine, and salt and water, may be poured over 
infested spots. 
Farmers arc recommended to dig pits in September, 2 or 3 
feet deep and a foot wide, fll them with horse-dunq. and cover 
over with earth ; on the first appearance of frost all the mole- 
crickets in the field will resort to these traps. 
Their increase would be so prodigioiLS were it not for the ex- 
traordinary habits of the females, that famine must ensue where 
thev took up their abode. 
Moles most serviceable in hunting and destroying them : it is 
unwise to extirpate that little quadruped. 
Grows and various strong-billed birds devour large numbers.
