1,071 Albizza procera or raintree being a very fast 

 growing tree, and doing well in the plains of Bengal, should 

 be largely grown for fuel. The fruits of this tree are very 

 sweet and cattle are very fond of eating them. .They are 

 probably as good for fodder as the carob-beans of the Medi- 

 terranian regions. Prosopis spicigera and mulberry have 

 been also mentioned as valuable fodder-yielding trees.

SII.OS. 



OILOS are built either above ground or below ground or 

 partly above or parly below, or on a slope. They are 

 either old buildings modified or unmodified, or they are new 

 ones specially constructed. A fourteen-inch brick or concrete 

 wall carefully lined with cement is all that is required. The 

 internal coating of cement should be as smooth as possible. If 

 an old room be converted in a silo the door-way requires special 

 arrangements for closing up before filling, and for opening 

 before commencing using the silage. This is sometimes done 

 by brick-work and sometimes by a double door of wood with 

 saw-dust in the intervening space. The cost of silos should 

 not exceed Rs. 10 per ton of capacity, a cubic ft. of silage 

 weighing 45 or 50 Ibs. Fifty cubic ft. should hold a ton. 

 Stack-silos are also common. A stack 30 ft. long by 15 ft. 

 wide (16 ft. at the base) and 14 ft. high would weigh about 

 100 tons. A pit at the side of a hill is the most convenient 

 situation for a silo as it can be filled from the top and the 

 fodder can be taken out from the bottom.

 behind the door-way, or just beneath the covering boards, great
