This list comprises only the expenses of a day's labor ; 

 if the operations should be continued one hundred days, 

 the expenses would amount to 19,250 francs. 



When the preparation of the juice and the manufactur- 

 ing of the brown sugar are completed, all the work people, 

 excepting the two refiners, are dismissed ; these a^e enough 

 for carrying on the operation of refining. The expenses 

 attendant upon this last operation, which continues till au- 

 tumn, are as follows : 



1. Wages of the head refiner, . . 1,000 francs. 



2. Wages of the second refiner, . 500 



3. Wages of a laborer, .... 250 



4. For animal charcoal, .... 300 



of 1000 lbs. is 6 firancs, 65 centimes. The expense of labor and ma- 

 nure are borne by the corn which is sown immediately after the dig- 

 ging of the beets ; the crops of corn are improved by interposing the 

 crop of beets between them, as the earth is rendered light, and the 

 frequent weedings free the ground from all injurious plants. 



* This price is based upon the situation of my own works in Tou- 

 raine, two leagues distant from the mines : it must vary with the dia* 

 tance and the difficulty of transportation.
