Operations permitted in free zone—In the free zones are permitted 
all operations of traffic, manipulation of goods and industry in which 
no alteration of the substance of the original article is involved. The 
most important are the manipulation of tobacco, requiring sorting out, 
packing and forwarding; coffee cleaning; and motor-car assembling. 
In addition there are special facilities for the warehousing under 
bond prior to the importation of the goods within the national 
customs barriers. This operation enables traders with foreign coun- 
tries to store goods until they are sold either at home or abroad. A 
lumber mill has been built in the free zone. The building was erected 
by the company on ground which is given free of rent for 10 years, 
but at the end of that period the property of the building reverts to 
the free port. 
Operations prohibited in free zone.—No industry, which in course 
of manufacture alters the substance of the goods involved, is per- 
mitted. It may be stated, however, that a scheme is in course of 
consideration to modify this rule for the purpose of increasing trade 
in this port, which is becoming rather precarious owing to the com- 
petition of the North German ports. 
Dispatch in unloading.—The Porto Vittorio Emanuele III is the 
more extensive and technically better equipped with cranes and lifts 
worked by hydraulic pressure from a pumping station equipped with 
accumulators. There are 87 cranes, of which 4 are of 3 tons’ capacity 
and the others of 1.5 tons. The latter aro in process of being strength- 
ened to lift 2.5 tons, in view of the increasing arrivals of American 
automobiles exceeding 1.5 tons in weight. Some 43 of these cranes 
are already in operation. There are 88 cargo lifts and 4 fixed hy- 
draulic cranes fitted to the upper floors of the depots. The hydraulic 
cranes are of the Bremen type No. 1885 and the derricks can be 
turned over an angle of 320°. 
The Porto Emanuele Filiberto Duca d’Aosta is, on the other 
hand, equipped exclusively with 24 electrically driven cranes, 4 of 
which are of 3 tons’ capacity and 20 of 1.5 tons. There are also 
16 electric lifts fitted on depots. The electric cranes turn over 
an angle of 360°. . 
Cargo is lifted by means of slings attached to a conical chal? 
acting as counterweight on a hook fixed to an iron chain of 10 meters
