Fig. 79. Longitudinal section of an outdoor storage cellar, 



1 2 feet long, built of concrete. The structure may be lengthened 



to increase the storage capacity, but additional ventilators 



must be provided 



side storage cellars usually are left with dirt floors, as a certain degree 

 of moisture is desirable. These cellars may also be made of concrete, 

 brick, hollow tile, stone, or other material. 



"The type of outdoor storage cellar just described, while low 

 in first cost, is short lived, as conditions are favorable to decay. The 

 concrete storage cellar, although higher in first cost, is permanent. 

 In the construction of a small structure suitable for the home it is 

 possible to make the roof self-supporting and to employ unskilled labor, 

 thus lessening the cost. It is a simple matter to waterproof concrete, 

 a feature highly desirable in a storage cellar. 



"The site for the concrete storage cellar should be selected with 

 the same considerations in mind as for the wood frame cellar, namely, 

 a well-drained, convenient location, preferably a side hill, into which 

 it may be built as shown in Figures 79 and 80. The excavation should 

 be just large enough for the dirt walls to serve as the outside form 

 for the concrete. For that portion of the wall which is above the 

 surface of the ground a board form must be used. The inside form 

 usually is made of boards held in place by scantling spaced about 

 18 inches apart. Temporary supports should be placed across the 

 top to carry the form, so that it will be of the size and shape desired. 



"The side walls and roof should be so constructed that there 

 will be no joints to weaken the structure. The form for the ceiling 

 may be slightly arched by setting a temporary line of posts through 

 the middle of the excavation. A plate placed on these posts a few
