the register, taking pains that it is spread out as much as possible. 

 Weight the lower corners of the cloth to prevent it from being blown 

 up by the draft from the furnace. 



5. Put back the grating, arranging it in such a way that the side 

 toward the cloth is propped up a little with bits of wood or wads of 

 paper. 



Method II. For registers in exposed situations where a bowl 

 of water would be likely to be kicked over : 



1. Inside the register, and a foot or two below the grating, place 

 some kind of receptacle for water. The receptacle should not be large 

 enough to prevent the flow of air. It may be hung from the grating if 

 necessary. 



2. From the grating, suspend one or two little curtains like those 

 already described. If two curtains are placed parallel the water can be 

 poured into the pans between them, and will not be likely to slop over. 



3. In using this device, it is important to fill the pans carefully in 

 order to avoid pouring water down the hot air flue. 



C. Houses Heated by Stoves 

 Keep an open kettle on each stove. A pan and curtain such as are 

 described under A, above, may be placed back of the stove provided 

 care is taken to avoid the danger of fire, should the cloth get dry.
