fumes of carbon bi-sulphide injected into the earth, why 

 should not this same application destroy the white grub, 

 wire and cut worm, squash beetle, and others ? A spoon- 

 ful of the liquid, injected by a syringe about the roots of 

 the plants to be protected, might work wonders. 



The Harlequin Cabbage Bug. The harlequin 

 cabbage bug is a very demon among garden pests, the 

 perfect insect one-half inch long, somewhat resembling 

 in shape a terrapin, having a hard shell brilliantly spot- 

 ted. It is a sap sucker, puncturing the stalks and leaves 

 of cabbage and other plants of the cabbage family, suck-

 first place among destructive bugs. It is particularly 

 fond of cabbage and turnip, attacking both in autumn 

 and spring, and is especially destructive on those plants 

 when shooting to seed. His firm has lost, on several 

 occasions, sixty to seventy acres of cabbage, and still

 caterpillar, feeding on nearly all broad-leaved vegetables, 

 especially cabbage, cauliflower and lettuce. It is the 

 larvae of a white butterfly of European origin ; Paris

 very early stages of cabbage growth, it is unsafe to apply 

 so poisonous an article to a plant which might enfold
