CULTURE OF THE SUGAR BEET.

In this estimate he admits a yield of sugar of all grades of 5.5 per 

 cent, the weight of the roots, and fixes the selling price of this sugar 

 at 60 francs per 100 kilograms, or $5,454 per 100 pounds, but he con- 

 siders that this price should, on account of the variations in market 

 rates, be fixed at a lower figure, or 55 francs per 100 kilograms, and this 

 would cause a loss of 30 cents per ton of roots worked. 



He claims 5.5 per cent, as the average yield in the French factories, 

 but it is evident that in very many it is higher than this. In case of 

 higher yield, the cost of extraction, and the quantity of the bye prod- 

 ucts obtained would be about the same. Supposing the following 

 gradation in the yield of sugar, and the selling price oo francs, for the 

 different yields of 6 per cent., G.5 per cent., 7 per cent., 7.5 per cent., we 

 should have, respectively, as profits per ton of roots worked, $0.15, $0.70, 

 $1.25, $1.80. 



These figures do not ;jeem so favorable for the manufacturer as those 

 I have been able to obtain directly from French manufacturers, through 

 the kindness of Prof. B. Corenwinder, and M. E. Macarez, of Lille, and 

 embodied in the following table, showing the cost of workiug, and the 

 results obtained for a series of four years for the campaigns of 1873-'74 

 to 1877-78, inclusive. 



The table will explain itself. 



Statement of expenses and receipts resulting from the transformation of one ton (2,'200 

 pounds) of beets into raw sugar, Nus. 7-9 to No. 13, molasses at 40°, and other residues — 

 the beets delivered at the works, the sugars delivered at station, molasses and other residues 

 taken at the works. 



[The figures of the tables give the averages of four factories, producing annually about 10,000 sacks 

 (220 pounds each) of raw sugar, and working by means of new processes and machinery, double satu- 

 ration of the juice, triple effect for the evaporation and boiling for crystallization (cuite en grains) 

 of the sirups.] 



DETAIL OF EXPENSES FOR ONE TON (2,200 POUNDS) OF BEETS. 



* The duty on sugar, equivalent to 73.50 francs, $14.90 per 100 kilograms (220 pounds) of raw sugar, is 

 not comprised in the figures noted here, neither in the expenses nor in the receipts. The public treas- 

 ury accords four months of credit to the refiner, who is charged with the payment of this tax, and it ia 

 not therefore included in the price of sale.
