THE MANAGEMENT OF FRAMES 159

 sash somewhat. And visit the frames a-t sunset, closing the 

 frames for the night, putting on the mats and shutters if 

 necessary. 



If you cannot make these four visits at just these intervals, 

 make your second visit just before school, and your third 

 just as soon as you return. And if you are so busy that you 

 can go but twice, go an hour after sunrise and at sunset. 

 When you go but twice, you are taking something of a risk. 

 For when before breakfast you have to decide what the 

 weather is to be, you will sometimes find the question puz-

And now, how to give this air ? Frames can be opened in

 triangular piece of wood, or a piece made in steps, so that the 

 sash may be left at any height one chooses. If lifted, raise 

 the side away from the wind, so that it does not blow directly 

 on the plants. Open but a little at first ; but as the plants
