occupy 28,000, or 7,000 cubic feet more than her 

 space. 



It is therefore apparent that only a due proportion of 

 each kind of cargo can occupy the entire space and 

 jointly weigh 350 tons. 



Let the average space per ton in the ship be ascertained 

 by dividing the space in the hold by the tonnage; from 

 the average dedu6t space per ton of dead weight, mul- 

 tiply the remainder by the tonnage, and divide by the 

 difference between the space per ton of light freight and 

 dead freight ; the quotient is the light freight, and the 

 difference between it and the tonnage is the amount of 

 dead weight goods. Thus :—
