CULTUEE OF THE SUGAK BEET. 



MANUFACTURE. 



Dabrunfaut determines from his own observations as the cost of pro- 

 duction 5.2 cents per pound avoirdupois for the intermittent process, and 

 4.8 cents for the continuous. Colonial sugars were at this time worth 

 1.40 to 1.50 francs per kilogram or 12.7 to 13.6 cents per pound, .and it 

 was stated to be impossible to produce them at a cost of less than 5.5 

 cents per pound in the Antilles. 



The above estimate of cost given by Dubrunfaut was for working 

 about 1 ,000 tons per annum. For working double that quantity the net 

 cost appears at that time to have been greater, and reached 5.8 cents for 

 the intermittent process and 5.4 for the continuous process. 



From this time the industry continued to spread rapidly, and to pro- 

 duce everywhere fruitful and profitable results, though, strange to say, 

 no record seems to have been kept of the statistics of production in 

 France until the year 1829, when it was stated at 4,000 tons. 



In Germany the industry did not revive until after 1835, when atten- 

 tion was called to it by Krause of Austria, and Schubarth of Prussia, 

 who went to France, the first in 1834 and the second in 1836, to study 

 the progress and condition of the manufacture. As a consequence of 

 these trips and the prominence given by the press of the information 

 they carried home with them, the culture of the beet was inaugurated 

 anew, factories were again erected in large numbers, and the industry 

 soon became so powerful as to be competent to contribute to the reve- 

 nue of the government.
