The farmer would have to provide storage for liis ]iress-cake or pulp. An 

 average of 2(3 tons would have to he reckoned with 84 per cent, extraction. A 

 silo of 30 cubic vards' capacity would sulliee. The dimensions for an overcround 

 silo would be 10 feet diameter by 12 feet high. It would cost probably about 

 £20. A pit silo might cost less. " It would be a permanent improA'ement. 



The cost of working a travelling juieery is estimated as follows: — 



Travelling Puicss Juicery. 



Working one shift of S hours; capacity, 2 tons an hour; 84 per cent, extraction.

Capital is estimated at £3,400. Depreciation is taken at 5 per cent, instead 

 of 4 per cent., and repairs at 6 per cent, instead of 5A per cent, in the previous 

 case. In the travelling juicery the fanner would pay a fixed price per ton of 

 dried juice for the extraction and evaporation, and would receive payment direct 

 from the central factory for his product. In this case he would take the chances 

 of higher or lower richness of his roots, but in the adjustment of prices payable 

 by the central factory he Avould get a higlier net return than from the stationary 

 juiceries; with roots of 15 per cent, he would net about 293., or even over 30s.. per 

 ton instead of only 27s. 6d. 



The total costs may now be placed alongside the Maffra values: — 



Costs at Juicery. Value at Maffra. Tossible Prolit.

 40% efficiency .. IS 14 1 I I 115 



In all the above estimates but lilth' latitude has been allowed beyond the per- 

 centages for contingencies. 



General Concliisioiift. — A general view of the above statements of possible profits 

 is now given, thus: — 



Infusion juieery — Wood fuel 



Coal fuel . . 

 Press juicerv — Wood fuel 

 Coal fuel 

 Travelling juicery — Wood only 



Thus, it will be seen that the possible profits from the operations according to 

 tliese estimates would vary in the case of a 75 per cent, efficiency of the evaporator 

 from a minimum of £1 8s. Id. to a maximum of £2 2s. 2d. per ton of sugar, and 

 in the case of only 40 per cent, efficiency from a minimum of Is. 3d. to a maximum 

 of £1 Is. 5d. The general average of these estimates is £1 4s. 



Divisio)i of Profits. — T'iie possible profits would have to be divided between the 

 central factory and the juicery in the case of the stationary juicery, and amongst 

 the factory the juicery and the farmer in the case of the travelling juicery. If
