PORT ECONOMICS 
merchants engaged in the business of importing and 
re-exporting, find it not worth while to submit to the 
Customs routine for the purpose of claiming the draw- 
back. 
In this country, the term Drawback is used in a similar, 
but slightly different, sense. It is a refund of the whole 
or part of the duty which has been paid on goods, which 
are re-exported as merchandise or ship’s stores, or used 
for non-dutiable purposes. 
MISCELLANEOUS RECEIPTS 
It would perhaps be impossible to sum up completely 
all the possible sources of income to a port authority. 
They may include, for instance, in addition to the principal 
rates and dues and rentals explained above, such incidental 
matters as— 
Charges for the hire of cranes and coaling appliances. 
Charges for weighing goods on quay. 
Cost of dunnage (timber for packing and storing goods) 
and charges for preparing ships for reception of cargo. 
Charges for surveying damaged cargoes and adjudicating 
thereon. 
Charges for the hire of graving docks and slipways. 
Ferry rents, possibly a royalty or percentage on ferries 
run by independent enterprise. 
Watching charges on vessels or goods. 
Charges for the use of artificial light (gas or electricity). 
Charges for the supply of fresh water to shipping. 
Recoverable costs for the removal of wrecks, with the use 
of floating craft for lifting purposes. 
Rental of dummy barges (used for breasting ships off 
from a quay wall), ordinary barges, boats, winches, gear, 
etc. 
Frequently, a charge is made for the removal of ships’ 
ashes and also for the provision of special barges to 
receive oil waste from bilges and the washings from ships’ 
holds.
