STOWAGE FACTORS.
The stowage factor is the average cubic space occupied by 1 ton
weight of cargo as stowed on board the ship after making reasonable
allowance for broken stowage, dunnaging and the packing of the goods.
We give some of those approximate figures here fox a few of the more
common class of goods, based on experience of shipments.
