pete with beet sugar in the markets of Europe or the United 

 States. 



The "Journal des Fabricauts de Sucre " says, that " the season 

 of 1865-6 developed the success of two highly important pro- 

 cesses, namely, the immediate carbonation without defecation of the 

 juice as it came from the press, and the perfection of the operation 

 of the improved filter presses. In the factories, where these new 

 methods were employed, their superiority was marked in com- 

 parison with the old system, by which, late in the season, it was 

 almost, and oftentimes quite impossible to make good sugar. 

 Beets that could not be successfully Avorked by the old process 

 were brought to the new establishments, where sugar of beautiful 

 quality, fit for direct consumption, was readily produced. And 

 what was still more remarkable, in as great proportions upon the 

 amount of beets worked as in the beginning of the season," 



The entire success of these processes, which, seeing in operation, 

 I have recommended the adoption of, has created the greatest ex- 

 citement among the manufacturers in France. The opinion is there 

 entertained that their employment will not only increase the aver- 

 age yield of sugar at least one per cent, on a hundred pounds, but 

 also improve the quality of the sugar several numbers. 



The remarkable results produced by these improvements have 

 attracted the attention of Englishmen; and the probability is, that 

 the manufacture of beet sugar will yet be established in Great 

 Britain, the country that not only tried to strangle the industry at 

 its birth, but also, when it had been successfully established on 

 her own soil, gave notice to the manufacturers, through its gov- 

 ernment, that an excise of five cents per pound would be placed 

 upon their production, upon the ground that it would interfere 

 with the prosperity of their West India possessions !

 the average production of sugar per acre from the cane in that 



island was 1,709 lbs.
