A Basis for the Valuation and Sale of Raw Sugars. — If p be the sucrose 

 in a raw sugar of purity j, affording a barrel syrup of purity m, the available 



sucrose is ^ X -A : . There is also produced barrel syrup, the quantity 



I — j 

 of dry barrel syrup being ^ X ^ —,. Let the value of a unit of dry 



barrel syrup compared with a unit of refined sugar be k. Then the equivalent

available sucrose is ^ x -^t r -\- kp x ^, — r.

Let c cents per lb. be the price quoted for refined sugar ; then the value 

 of raw sugar will be in cents per lb.

where / represents the sum of the refiner's expenses and profits. 



li k = T, the left-hand part of the expression reduces to c x ^ = c X 



Dry Substance, in which case the refiner buys dry substance and not sugar. 

 The refiner's expenses will, however, increase as the purity falls, and there- 

 fore another term should be added to the expression. This term would be 



of the form^p-, where ^ is a constant and/(;") represents the increased ex- 

 penses due to faU in purity, so that the complete expression for the logical 

 valuation of raw sugars will be cp \ —. ^ — \— I — . , .. . 



A basis of sale such as the above would be fair to both producer and refiner, 

 and would allow the former to make sugars of low water content, thus elimin- 

 ating danger of deterioration and permitting him to economize in expense 

 of containers and freight. The refiner similarly would pay for what he re- 

 ceives, including the barrel syrup. If the sale is conducted on a basis of

available sucrose only, the expression will be cp \ -r^ : y— I — y-j-7\-
