light, or else look at the picture of the quince leaf, and 
study carefully the make-up of the blade. 
You see that this is divided lengthwise by a heavy 
rib which juts out on the lower side. From this 
“midrib,” as it is called, run a great many smaller lines. 
iinese, are called)“ veins.” And from these branch ott 
still smaller veins that bear the name of “‘ veinlets.”” And 
somewhat as the paper is stretched over the sticks of a 
kite, so from the leaf’s midrib to its edge, and from vein 
to vein, is drawn the delicate green material which 
makes up the greater part of the leaf. 
What I wish you to learn this morning is, ow fo look 
at a leaf. 
Before using our brains rightly, we must know how 
fe@-use our eyes.. If we see a thing as. it. really 1s, the 
chances are that our thoughts about it will be fairly 
EOETECL. 
But it is surprising how often our eyes see wrong. 
If you doubt this, ask four or five of your playmates 
to describe the same thing, — some street accident, or a 
quarrel in the playground, which all have seen, or 
something of the sort, —and then I think you will 
understand what I mean by saying that few people see 
correctly.
