FOREIGN TRADE ZONES
sels and on each are two railway tracks. On the bank between them
is a loading platform and over this there are eight pneumatic elevators.
With these latter eight different part cargoes of grain can be dealt
with at the same time and transported in different directions. They
may either be weighed automatically on the jetty, put in sacks, and
loaded into the train, or transported by means of chutes and discharged
 into barges from a lower levee, or in bulk over automatic
weighers, loaded directly into the barges. It is also possible to chute
the grain on to rollers and to transport it by this means to the warehouse,
 after which it can be stored in silos or on the floor or may be
forwarded by rail. In the same way grain can be discharged again
from the warehouse into seagoing vessels or barges. The capacity of
the 16 pneumatic conveyors is about 4,000 to 8,000 tons per 8-hour
day, the average annual capacity about 800,000 tons. This capacity
may be more than doubled by increasing the working hours. The
warehouses for grain are not particularly well equipped for storage
over long periods, but are most suited for storage in transit, to
equalize any irregularity in the separate consignments from the seaport
 to the inland destinations. Nevertheless the warehouses are
provided with all apparatus for removing the grain; for example, to
take it from one place to the other, or to dry it in hot air. The installation
 was made during the early years of the war, and an addition is
now being carried out. Besides these fixed installations for handling
grain, Bremen has also a State-owned grain elevator.
Reconsignment and transhipment trade.—In regard to the reconsignment
 as well as to the transshipment trade no special figures are
available. The principal commodities in this business, however, are
cotton, tobacco, drugs, rice, coffee, grain, and bananas.
Manufacturing in free zone.—In the free port zone no manufacturing
is done. Various industries, however, have plants just outside of
the free zone or on the docks within the customs limits of Germany.
Although in olden times Bremen was mainly .a place for staple and
transit goods, but was not so important a consumer and industrial
user, it has developed during the last few decades, and largely by
the construction of its free port, to an important production center.
Many industries have settled in and near the city of Bremen owing
to the free port. In the State-owned territory Bremen set aside abou?
6,500,000 square meters of territory along the river or its harbors, of
which at present about one-third is still available, for industry
The main local industries are lumber mills; rice, oil, and flour mills;
spinning and weaving mills for cotton and jute; oil refineries; choc
olate, rubber, and linoleum factories; iron smelters; and a large ship’
building industry.
Shipbuilding and ship repair in free zone.—In regard to shipbuilding
and repair work done in the free port zone, the Deschimag (Deutsche
