provide a dead air space. If the inner lining is made 

 up of lumber, the boards should run parallel with the 

 rafters, rather than at right angles to them, so that 

 any condensed water may run off to the eaves rather 

 than faU from each joint. Ventilation should be 

 encouraged by means of top ventilators on the roof. 

 These should be provided with dampers, manipulated 

 and controlled by ropes extending to the passage- 

 way. Small windows installed above the foundation 

 line in the walls will admit air from below and induce 

 a better circulation. The windows may be screened 

 with an iron netting in order to keep out mice. 



There are two ways of storing cabbage — ^in bins or 

 on shelves. The latter is preferred because there is 

 less bulk to undergo a sweat, and each individual 

 cabbage being exposed to more air prevents rotting. 

 In storing, the cabbage should be placed with the 

 stem end upward so that all possible moisture may 

 readily nm off and not be caught and held by the 

 head leaves. 



So far as possible, the temperature of the storage 

 house should be maintained at about thirty-four 

 degrees F. throughout the storage period. As soon 

 as the house is filled, it should be kept closed during 

 the day and be opened at night in order to benefit 

 from the cool outdoor air. During extremes of cold 

 weather, ventilation should be reduced to a minimum 

 and the house kept warm by an oil heater to prevent 

 freezing of the cabbage. The Danish BaU Head, 

 from imported seed, seems to be an ideal cabbage for 

 storage.
