TYPICAL LESSON PLANS 131 



The worms that were left out of doors dropped down 

 to the ground and made their cocoons under the dead 

 leaves or other rubbish, or just under the surface of the 

 soil. The second brood of sawflies often eat up every leaf 

 left on the bushes by the first brood. When these are 

 grown up as larvae they spin cocoons just as the others did, 

 but instead of the sawflies coming out in two or three weeks 

 they remain as pupae in the cocoons all winter and come 

 out in time to lay eggs on the first leaves that appear in the 

 spring. 



If these cocoons are close to the surface, or under dead 

 leaves, who will suggest a way to get rid of some of them ? 

 Rake up the trash in the fall and burn it. Spraying the 

 bushes with hellebore in the spring as soon as the worms 

 begin to appear is usually effective. It may be necessary 

 to spray several times. 



The children will be interested to know that these 

 worms are not natives of America. They were accidentally 

 imported from Europe into the New England states about 

 fifty years ago. Since then they have spread over the 

 greater part of the United States. 



BLUEGRASS. Fifth Grade 



Problems. What are the characteristics of the bluegrass 

 that make it a good lawn plant ? What may we do to keep 

 our lawns beautiful ? 



The work should begin with outdoor observation of 

 the bluegrass during the latter part of winter or very early 

 spring. Note the condition of the grass at this time. 

 What indications have you that it has lived all winter?
