Since the opening of the St. Gothard Tunnel nearly all the alimentary
provisions that Italy sends to the British Isles pass through Antwerp.
In 1882 82,000,000 eggs and 30,000 pounds of fruit were shipped there
for England. The greater part of these came from Italy. Antwerp has
become also an important port for emigrants; 35,125 embarked in 1882,
out of which number 3,055 were bound for New York. The city was always
destined, from its topographical position, to be at the head of a very
considerable traffic; political reasons alone for many years prevented
this being the case. These have happily now disappeared, and, since
1863, when the "Scheldt was liberated," the progress of commerce has
been more rapid than even the most ardent Antwerp patriot dared hope. At
that date the toll of 1s. 11d. on all vessels going up the river, and of
7½d. on vessels going down, was abolished, and reforms were introduced
among the taxes on the general navigation; the tax on tonnage in the
port itself was abolished, and the pilot tax was lowered. The results of
these measures became immediately apparent. Traffic increased with
such rapidity that in 1876 the crowding on the quays was such that the
relation of the tonnage to the length of the quay was about 270 tons per
yard, which is four times as great as at Liverpool.
A few words now, briefly, as to the nature of the important works[1]
completed at Antwerp. They were commenced in 1877, and have opened for
the port an era of prosperity such as was never experienced even during
the sixteenth century, the zenith of her splendor. These works have
cost £4,000,000, and have necessitated the employment of 12,000 tons
of wrought iron, of 490,000 cubic yards of brickwork and concrete, of
32,000 cubic yards of masonry, and of more than 3,300,000 cubic yards
of earthwork in filling and dredging, etc. The quay walls run the whole
length of the town, a distance of rather more than two miles. It rests
on a foundation laid without timber footings, and giving a depth of
twenty-six feet at low water, sufficient drawing for the largest ships
afloat. Beyond this wall are the real quays, which consists of first a
line of rails reserved for hydraulic cranes serving to unload vessels
and deposit their cargo railway trucks; secondly, a second line of rails
parallel with the first, on which these trucks are stationed; thirdly,
sheds extending toward the town for a width of one hundred and fifty
feet, and covered with galvanized iron sheetings. A third line of rails
parallel with the two others runs from end to end of these sheds, and a
number of lines placed transversely with this one connect it by means of
spring bridges with, fourthly, four more lines also parallel with the
quays, whence the goods start for the different stations, and thence to
their destinations. The total width of these immense constructions is
about three hundred and twenty feet. Such is their magnitude that about
