TOPICS FOR WRITTEN ANSWERS 
Teachers will discuss freely the following topics, not neces¬ 
sarily confining themselves to the lesson, but use information 
obtained from other sources. Write freely on the questions as 
topics for discussion rather than questions to be answered briefly. 
Send answers to the Superintendent as soon as completed, 
and, if satisfactory, other lessons will be forwarded at once. In 
no case will a lesson be sent until the questions of a previous 
lesson are answered. 
1. On what plants do you find green lice? (At the time of your study?) 
2. Do these insects prefer the upper or lower side of leaves? 
3. What is parthenogenesis? Does it apply to this subject? (Consult 
your dictionary.) 
4. Why do ants run up cherry trees and other plants ? 
5. In what form do aphides pass the winter out of doors?
