46 HOW TO BUILD A SILO. 



variety of conditions of climate and local environment has brought 

 ou,t some of the demerits of this type of construction which at 

 the outset could not have been foreseen. For instance, the wood 

 lining has been found less satisfactory than cement, and hence 

 it Is recommended that these silos be cement lined. Many of the 

 King silos are lathed and plastered and have proven very satis- 

 factory, having done service for ten years. 



"Clap boards have been found unsatisfactory for the outer 

 siding and it is recommended that steel siding or some of the 

 roofing paper, ruberoid, or lath and plaster be used in their stead 

 as will be- described later." 



Painting the Silo Lining. 



It is impossible to so paint a wood lining that it will not become 

 wholly or partly saturated with the silage juices. This being true, 

 when the lining is again exposed when feeding the silage out, 

 the paint greatly retards the drying of the wood work and the 

 result is decay sets in, favored by prolonged dampness. For this 

 reason it is best to leave a wood lining naked or to use some anti- 

 septic which does not form a, water-proof coat. 



The cost of such a silo as that described in the foregoing 

 pages, is estimated by Prof. King at about 12 cents per square 

 foot of outside surface, when the lining consists of two layers 

 of half-inch split fencing, with a 3-ply Giant P. and B. paper be- 

 tween, and with one layer of split fencing outside, covered with 

 rabbetted house siding. If built inside of the barn, without a roof 

 and not painted, the cost would be reduced 3 cents per square foot, 

 or more. Silos of this type, 30 feet deep, built outside, provided 

 with a roof and Including 6 feet of foundations are stated to cost 

 as follows: 13 feet inside diameter (80 tons capacity), $183.00; 

 15 feet diameter (105 tons capacity), $211.00; 21 feet diameter 

 (206 tons capacity), $298.00; and 25 feet diameter (300 tons 

 capacity), $358.00. 



Complete specifications and building plans for a 300-ton silo, 

 of the kind described in the preceding pages, are given in Prof. 

 WoU's Book on Silage. The dimensions of this silo are: Diameter, 

 26 feet; height, 30 feet. 



According to our present knowledge this form of silo Is most 

 likely the best that can be built; it is a somewhat complicated 

 structure, calls for -more time and skill for its construction, and
