ONIONS 147 



sets. ■ These are tiny onions, already partly grown. 

 They may be put in as soon as the bed is ready in 

 the spring, and require no care after planting, except 

 cultivation. They are buried two inches deep, 

 three or four inches apart in the row, and soon sprout, 

 growing to a large size and maturing six or seven 

 weeks before seed-planted onions would ripen.

Enemies. — Reports from various parts of the 

 country show that the onion is still free from enemies 

 which greatly endanger the crop. The thrip, a 

 Httle insect that punctures the leaves and sucks the 

 sap, can be controlled by kerosene emulsion. The 

 cutworm, which will attack young onions, can be 

 poisoned with cutworm bait — the arsenate of lead 

 and bran mixture.
