The Modern Silo. 



327 



cow stallB, and two or moi'e doors in the superstructure reduce the 

 labour considerably. 



A section of a good pit silo is shown in Fig. 8. In tilling a deep 

 pit caution is required in respect of the carbonic acid gas, and the 

 ofreen stuff should be allowed to fall into it fi'om the cutter for a few 

 minutes before anyone descends to tread down the silage. If the pit 

 is less than 18 feet in depth means should be adopted for weighting 

 the material when first put into the silo. A covering of bags, and two 

 feet of earth or stones will serve this purpose.

The Stave Silo- 



The stave silo is not so well adapted to Australian as to American 

 conditions, on account of the way our hardwoods shrink and warp as 

 they dry. If built of Oregon or red deal the expense is much greater 

 than a framed silo built in the way already described. The one shown 

 in Fig. 9 was erected last year by Mr. Carpenter, Heywood. It gives 

 first class results as far as quality of the silq,ge is concerned. The 

 dimensions are 13 feet diameter/and 20 feet high. The cost was 

 about £50.
