HOW TO DESTROY INSECTS. 35

 the plants are in full growth, and weaken them much 

 by causing the leaves to turn a sickly color and 

 fall off, so that the flowers are neither so plentiful nor so

 water from passing freely. 



It is not advisable to use this or any other mixture

If by any accident plants become frost-bitten, 

 they may be restored by immersing them immediately,
