SECTION V. 



On the Products op a Beet Sugar Manufactory.* 



In estimating the value of the products of a sugar man- 

 ufactory, I will suppose that 10,000 lbs. of beet roots are 

 operated wpon each day ; however, as beets cannot be em- 

 ployed till after they have been carefully trimmed, there 

 is perhaps a loss of ^ part of that weight ; thus, in order 

 actually to work upon 10,000 lbs. of beets, it is necessary to 

 employ 12,000 lbs. so as to allow for this loss. 



The products of a sugar manufactory are of two kinds ; 

 the first consists of the sugar, the second is furnished by 

 the molasses, the mash, and the trimmings of the beet 

 roots. 



ARTICLE I. 



Of the Product in Sugar. 



The product of the concentrated sirup obtained from 

 10,000 lbs. of trimmed beets will fill eight moulds, each 

 of which will contain 47 lbs. of good brown sugar; this 



makes 376 lbs. 



The molasses obtained from the moulds 

 furnishes ^ as much sugar as is ob- 

 tained by the first operation, equal to 62§ 



Total, 438§ lbs. 

 This quantity of brown sugar will, when refined, produce 

 at least ^^y^^ of very good double refined sugar ; and -^-^ 

 of sugar of an inferior quality obtained from the molasses 

 and sirups ; the whole quantity of sugar being -f^^. 



According to this, the average quantity obtained by an 

 operation skilfully conducted is, 



In sugar of the first quality, . . . . 187 lbs. 

 In sugar of the second quality, ... 60 



Total, 244 lbs. 



• In the estimate which follows, I have always valued the products 

 at the lowest rate, and the expenses at the highest.
