THE LEAF. 



19 



When we observe a thing, we not only look at it, 

 but, as we look, we think particularly about it. For 

 instance, after these exercises, when you look at a 

 leaf, you will think, what parts has it ? and, is it net- 

 veined or not ? You will observe these particulars 

 about it. 



THE SCHEDULE. That you may be sure to look 

 at plants with care, and that your teacher may see 

 what you think about them, little diagrams, called 

 schedules, are used, in which you are to write down 

 what you observe. They have questions written 

 upon them, which you are to answer by studying the 

 plants themselves.

XOTE. It will be observed that the attention of the child 

 is restricted to one additional point at each exercise. This 

 will prevent the confusion of ideas which is liable to arise 

 when several new features of plant-structure are presented to 

 the mind at the same time.
