GOOD HEALTH 



There is just one other way. Stand with your left 

 side to the window. Now everything is perfect for read- 

 ing and for writing too. The light shines on the white 



~ ~~ page ; it is reflected 



up to your eyes and 

 you see the words 

 easily. You do not 

 face the light, and if 

 you are writing, the 

 shadow of the hand 

 falls where it does not 

 cover anything. 



Whatever kind of 

 light is in the room, 

 the rule about the 

 right way to sit is 

 always the same. 

 Desks should never 

 face the window, and 

 blackboards ought to 

 be opposite the win- 

 dows and not between 

 them. This not only 



saves the eyes from being dazzled but makes it easier to 

 read what is written. Notice all these points for yourself. 

 You should never strain your eyes ; that is, everything 

 you read in the schoolroom should be easy to see.
