The surface layer, which rots to a depth of from 3 to 6 inches, 

 seals the mass below, no further covering- being necessary. 



After feeding- begins, which may be at any time after active 

 fermentation has ceased, a sufficient quantity, say from four 

 to six inches, must be fed off daily to keep ahead of mould and 

 decay which results from each fresh exposure to the atmos- 

 phere. The number of cattle fed should govern the diameter 

 of the silo — if 20 hea<l of cattle are to be fed 30 pounds silage 

 daily, a 1 (3-foot circular silo \vould permit of sufficient removal 

 to keep in advance of decay. Silage weighs from 35 to 60 

 pounds per cubic foot. Other things being equal, the deep,

 fodder mass becoming more compacted, thus excluding more

Silos are now constructed of wood, brick, stone and con- 

 crete, and of from 50 to 350 tons capacity. Wood is, of course, 

 the cheapest in first cost and is the material most used. There 

 are several methods of construction ; the stave silo, on the 

 plans of which the Kamehameha silo is built, is the simplest 

 and cheapest of the round form, but has some short-comings, 

 chief of which is its tendency to dry out and shrink when 

 empty, making it difficult to restore it to an air-tight con-
