so as to allow circulation of air. A little more room 

 is required at the sides so as to open and close the floor 

 ventilators. Some plans call for eighteen inches of 

 space at the end of the house between walls and bins so 

 that the ventilators may be opened and closed by hand. 

 By making a long handle of one inch by one inch strip 

 and attaching to ventilator, the ventilators may be op- 

 ened and closed from the passage way, thus giving bin 

 space for one hundred and eighty bushels of potatoes. 



In a twenty by twenty foot house there should be a 

 ventilator in each corner of the house, as shown in Fig. 

 1. These ventilators should be six inches wide and 

 twelve to fifteen inches long and fit with a sliding lid 

 that may be opened or closed at will. An eight by 

 eight inch or ten by ten inch ventilator should be placed 

 overhead in center of room, as shown in Fig. 3, and 

 •covered to keep out the rain. These are easily made 

 by nailing together in box fashion and extending the 

 box through the ceiling and roof. The lower end of 

 the box should be provided with a closely fitting door 

 or shutter which may be closed when desired.
