SUGGESTIONS TO THE TEACHER 
Spiders may be found at any season of the year. Let 
the pupils bring any kind, for this lesson treats of them 
collectively. 
Have an empty egg cocoon, if not a full one, to be torn 
apart. 
Carefully follow the course of the spider in constructing 
the web illustrated in this lesson, having the enlarged draw¬ 
ing upon the blackboard. 
Find how many eyes can be seen in each specimen spider. 
A magnifying glass is indispensable in these studies for the 
best work. 
Draw a web thread from the spinneret. Young spiders are 
better to work with than old ones. 
If the season is favorable, find a good fresh web and its 
spider near the school house, and go there with the class to 
make observations and talk about spiders. 
Ask the pupils questions about the specimen spider or its 
web that will require close observation, as, ‘‘How many 
joints in a spider’s leg ?”
