under natural conditions. If none appear upon an apple or wild 

 cherrv tree near the school-house, the teacher should transfer a 

 colony to such a tree (Fig. 26). This may be done by fastening 

 a twig with an egg mass upon it to a branch of the tree. If too 

 late to get the unhatched eggs, get a nest with the small worms 



in it and tie that to 

 the convenient branch 

 instead. This study 

 of the insects out of 

 doors is very neces- 

 sary in discovering 

 their normal habits. 



Lesson II. 



The Caterpillars. 



(Fig. 29.) 



If the eggs hatch before the 

 leaves appear, upon what do the 

 caterpillars feed ? 



How long after hatching be-

 formed ? 



yj;/jr. In the fork of the

when, as is the case out of doors, the tent is spread in a fork of 

 the larger limbs, these limbs afTord two branching roads for the 

 caterpillars to follow in searching for food. 



Let the pupils make drawings of the tent as soon as it is 

 large enough to be seen well. 



What is the color of the caterpillars when they are a week old ? 



Upon what do they feed ?
