covtT of 6 by \ inch lining boards is all that is required. The sides and 

 bottom floor are secured by cleats of 3 b\ i inch oregon at 6 feet dis- 

 tances. On the upper floor, which is 5 inches below the upper edge of 

 box It is advisable to nail two 6 by | inch boards cut down to 5^ inches 

 to form a groove for the chain to run in. The adjustable bearings sent 

 with the elevator chain, slats and sprocket wheels are attached by bolts. 

 The end of the box is put in as far as jjossible below the chaffcutter, an(l 

 a shoot made with pieces of sheet iron or of wood to connect to cutter, 

 tho whole being boxed in as far as possible. The drive from the cutter 

 will send the slats up the top or the bottom floor according to the side fed 

 from. Looking towards the silo, if the feed be from the right hand, the 

 elevator will work up the bottom floor. This is the most advisable, as the 

 throw of the cutting wheel is then assisting to run the cut stuff clown into 

 the foot of the elevator. It will, however, work satisfactorily, feeding 

 from the other side, so that the cutter may be put where most suitable for 

 feeding. 



The following is the list of material required for the 60-ton silo 

 specified. Some of the items are slightly in excess, in order to meet con- 

 tingencies : —

The cost may be computed from above list. The present contract price 

 for all the above is ^30 2s.. but the operation of the proposed tariff 

 which is still under discussion, has raised the cost 27s. mainlv on the 

 iron items. The cost may now be set down, on trucks, Melbourne, at 

 ^31 los., of which ^5 8s. is for the elevator. With an experienced 

 builder assisted by three handy men, the whole work of erection, including 

 construction of elevator, should be completed within four or five days. 

 After the silo has been erected some time, and the greenness of the wood 

 considerably lessened, the Avhole of the woodwork, and in anv case, the 

 lower 3 feet, including I)oth treble hoops should be tarred, the tar being 

 applied hot. The inside of the iron should be lime-washed as it is nailed
