table cellar must be ventilated 

 carefully, for one night's neglect 

 in closing the window may mean 

 an entire loss of the winter sup- 

 ply. A pail of water placed in 

 the center of the room mil sup- 

 ply sufficient moisture. Keep a 

 standard thermometer hanging 

 from the ceiling in the center of 

 the room. Keep water in the 

 furnace and a pail of water near 

 to absorb the gas. Never allow 

 the furnace gases to get into the 

 root cellar. If you only have 

 room for a few large boxes in 

 the root cellar, cover the outside 

 of each mth beaver board, place 

 a ventilator in the center of each, 

 fill in the roots and cover them 

 with five inches of soil. Place the box as far from the furnace 

 as possible. Alsq place two strips of board for the box to rest 

 on, so that the air may circulate under it.
