lesson should be given guardedly so as not to encourage the 

 children to cruelty in killing insects. The teacher should always 

 try to inculcate in the child reverence for life, that wonderful 

 force, which we can so easily take from a creature but which 

 we may never give back. It is better to appeal to the child's 

 sense of justice in giving this lesson. The teacher may vary it to 

 suit her own ideas, but in substance it might be given as follows : 



" All life is sacred ; the smallest worm has as good a right 

 to live in the sight of God as you or any child has. Life 

 should never be taken except when necessary. However, no 

 being has the right to interfere with the rights of another. 

 Neither the child nor the worm has any right to trespass upon 

 the property of any one else." 



" Let us see whether these caterpillars are trespassers or not. 

 The farmer works hard to earn the money to buy the land upon 

 which the orchard is planted ; he works hard to earn the money 

 with which to buy the young trees ; he works hard to set out 

 the trees and cultivate the orchard : therefore the orchard and 

 the fruit of it are his property, and he has a right to drive away 

 all thieves. If men or children steal the fruit, he has a right 

 to appeal to the law and have them fined or imprisoned. If 

 worms come and injure the tree by eating up the foliage, he 

 has a right to keep them out if he can. The leaves are neces- 

 sary to the tree, for if they are destroyed the tree cannot get 

 the air it needs to keep it vigorous and enable it to mature its 

 fruit. We have seen that these caterpillars destroy the leaves, 

 and thus do great injury to the apple crop. We therefore have 

 a right to destroy these little robbers, as that is the only way 

 we can keep them out of our orchards." 



How may they be destroyed ? 



The egg masses may be collected in winter and early spring 

 from young orchards, and be burned. 



In old, large trees we must wait until later. Ask the pupils 

 the following questions : 



At what times did we find the worms in their tents ? Ans. 

 Early morning, late afternoons, and during cold, dark days. 



If we should destroy the tents in the middle of a warm,
