A STUDY OF LEAVES. 



VERNATION. 



The folding of leaves in the bud is called verna- 

 tion. It is interesting to observe the manner in 

 which they are placed in relation to one another, 

 and also to notice whether each leaf in itself is flat, 

 folded, or rolled, 



If winter buds be examined, it will be found 

 how carefully they are protected by scales. Some- 

 times they are covered with varnish or a dense coat 

 of hairs to keep out Jack Frost.
