either in regular root cellars (see figure 28, page 84) or in barn 

 cellars. The latter are made frost proof, but are provided with 

 sufficient ventilation to maintain a low temperature, and sufficient 

 humidity to prevent excessive evaporation from the tubers. This 

 type of storage equipment is more desirable for persons engaged in 

 the production of seed potatoes than for those who grow potatoes 

 for consumption, unless they are within easy reach of the market 

 at all seasons. Seed growers of the extreme North generally plan 

 to move their crop in the fall to warehouses at distributing points,

or to place it as near as possible to the points at which it is to be 

 used for seed purposes. In fact, dealers who handle seed potatoes 

 make it a point to purchase their stock and have it in storage the 

 previous fall before danger of loss from cold weather occurs. 



Carriage houses and barns are frequently constructed with base- 

 ments or cellar rooms for potato or cabbage storage, the chief 

 requisite being a frost-proof room, free from moisture and pro- 

 vided with ventilation for the purpose of controlling the tempera- 

 ture of the room. The same principles hold in the construction of 

 root cellars, although such cellars are usually independent structures 

 built either into a hill or only partly below ground.
