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

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



*j yyi 



sucrose is p X ^ . There is also produced barrel syrup, the quantity 

 j (I m) 



y a 



of dry barrel syrup being p x / __ m }' Let the value of a unit ' of dr y 

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



available sucrose is p x -A r + kp X T-J 



; (i - m) ; (i - w) 



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

 of raw sugar will be in cents per Ib. 



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



If k = i, 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 former, where q is a constant and/(/) represents the increased ex- 

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

 valuation of raw sugars will be cp | -ry^ ~~ Jr\ __ / _ ^ 



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
