thicker on the outside or the inside of each scale, and whether it 
is equally abundant on all the successive pairs. 
What is the probable use of this coating? 
Note the delicate veining of some of the scales as seen through 
the magnifying glass. What does 
this mean? 
Inside the innermost pair are 
found two forked woolly objects; 
what are these? 
Compare with Figs. 87 and 107. 
Their shape could be more readily 
observed if the woolly coating were 
removed. 
Can you suggest a use for the 
woolly coating? 
Examine a terminal bud in the 
same way in which you have just 
studied the lateral bud. 
Does it contain any parts not 
found in the other? 
What is the appearance of these 
parts ? 
What do they represent ? 
If there is any doubt about their 
nature, study them further on a 
horse-chestnut tree during and im- 
mediately after the process of leaf- 
ing out in the spring.

Ganong’s Teaching Botanist, pp. 208-210. If some of the buds are studied at 
home, pupils will have a better chance to examine at leisure the unfolding 
process.
