A marvel of the age
One of the marvels
of the mid-nineteenth century was the electric telegraph, an invention which dramatically
changed the nature of communications throughout the world.
Experimentation
earlier in the century had paved the way for major technological developments: the
invention of a simple form of electric telegraph equipment by the Russian, Baron
Schilling; the development of the five-needle electromagnetic telegraphic system by the
English partners William Fothergill Cooke and Charles Wheatstone; and the creation of a
standard code by the American, Samuel Morse.
The effect of these
developments was to rapidly expand communications systems throughout the world. Soon,
telegraph wires were slung over the length and breadth of America, Britain and Europe.
As inland telegraph
systems burgeoned, the urge to forge international links grew and British, American and
German companies experimented to find a suitable form of insulation for cables which could
be laid on the sea bed.
In 1849, a
successful trial was held using a ship-to-shore wire over which messages were exchanged
from London to a vessel in the English Channel. The wire was insulated with gutta percha,
a latex substance from trees in the Malay Peninsula.
The following year,
Jacob and Joseph Watkins-Brett laid the first submarine cable from Dover to Cape Gris Nez
in France. Messages were garbled and the wire failed within twenty-four hours, but a
second successful cable was laid in 1851. This was insulated by tarred hemp and galvanised
iron wires with a covering of gutta percha.
Soon there was a
boom in cable production and British companies were formed to lay cables to all parts of
the globe.
By 1870, there were
cables linking Suez to Bombay and on to Madras, Penang and Singapore; but perhaps the
greatest feat was the laying of the trans-Atlantic cable by the vessel The Great
Eastern in 1866. Several previous attempts to lay the cable had failed, at a cost of
hundreds of thousands of pounds.A great and wondrous event ...
Australia's first
telegraph line was opened between Melbourne and Williamstown, Victoria in 1854, and others
followed in rapid succession. In 1859, the continent's first submarine cable was laid
across Bass Strait, laying the telegraph system of Tasmania to that of the mainland.
Eleven years later,
the British Australian Telegraph Company (BAT) was formed to link Australia direct to
British telegraph cables, by extending the cable from Singapore via Java to Port Darwin.
South Australia was
awarded the contract to lay the overland telegraph from Port Augusta to Port Darwin, the
agreement being that the landline would be completed no later than 1 January 1872.
Charles Todd was
chosen to supervise the project and divided the work into northern, central and southern
sections; the central section he supervised himself. However, the wet season, disease and
transport problems delayed construction on the northern section, and it was not until 22
August 1872 that the overland telegraph was completed.
Meanwhile, the cable
laying vessels Hibernia and Edinburgh were paying out cable towards
Banjoewangi in Java; on 20 November 1871, the task was completed.
But due to the
failure of the Port Darwin-Java cable just before the overland section was completed, and
the problems with the overland telegraph, it was not until 22 October 1872 that messages
could be sent direct from London to Adelaide.
The following month,
the cable was extended to Sydney.
The impact on
Australia's social, economic and political future was enormous. No longer did news have to
come by sea, often taking a year or more to exchange letters.
Direct international
trade was more than possible, and Australia could take its place on the world political
stage.
In 1873, three
British companies, The British India Extension Telegraph Company, The British Australian
Telegraph Company and The China Submarine Telegraph Company were amalgamated to form the
Eastern Extension Australasia and China Telegraph Company (Eastern Extension).
This company's first
major work was to lay a cable between Australia and New Zealand. The cable, from La
Perouse to Wakapauka, opened for traffic on 21 February 1876.
By the turn of the
century, the Banjoewangi-Port Darwin cable had been duplicated (1880), a third cable had
been laid between Banjoewangi and Roebuck Bay (1889), the New Zealand-Australia cable was
duplicated (1890), and Australia was linked to New Caledonia by a cable which was laid
from Bundaberg to Mon Repos (1893) by a French company.
In 1902, the Eastern
Extension Company lost its monopoly on international telegraph systems in Australia,
although moves to set up a second cable company had been made as early as 1879, under a
plan to link Great Britain to all its greater colonies. It was proposed that this cable
would only pass through British territory; the concept became known as the All Red Route.
In 1896, a Pacific
Cable Committee was appointed to consider all aspects of the proposal, and in 1901 the
Pacific Cable Board was established with eight members: three from England, two from
Canada, two from Australia and one from New Zealand.
The Board was
responsible for management of the Pacific Cable and was empowered to obtain tenders for
surveying and laying a cable from Vancouver to Fanning Island, Norfolk Island, New Zealand
and Queensland.
Funding and
ownership of the cable was shared between the British, Canadian, New Zealand, New South
Wales, Victorian and Queensland governments, and cable laying commenced in 1902.
A new cable vessel,
the Colonia, was built; it was capable of holding the 8000 tonnes of cable required
for the Bamfield to Fanning Island section. By the end of the year, the cable was open to
traffic, having cost about two million pounds to complete.
In reply, the
Eastern Extension Company lowered its rates and began laying a cable across the Indian
Ocean to rival the Pacific Cable Board's service. This cable would
travel from Mauritius to the Cocos Islands, on to Perth and finally to Adelaide.
Construction of the Cocos to Perth section was completed in 1901, and the Perth to
Adelaide section opened a year later.
By the 1920s,
increased traffic slowed cable operation, and in 1926, to compete with the newly
introduced beam wireless system, both companies duplicated their cables with new loaded
cable, This had a thin wire permalloy wound spirally around a copper core to increase its
inductance. The duplicate
Pacific Cable was laid by the CS Dominia which had been specially built for the purpose.
Colonial
governments, which had subsidised the construction and maintenance of the Pacific Cable,
became alarmed when their revenue fell dramatically in 1927 after the introduction of beam
wireless.
An Imperial Wireless
and Cable Conference was held in London in 1928, and it was decided to recommend to the
British Parliament that the overseas cable and wireless services be merged into one
system.
The Pacific Cable
Board and Eastern Extension Company became part of Imperial and International
Communications Ltd in 1929, which in turn was operated by Cable and Wireless Ltd from
1934.
All in a day's work
MANY EMPLOYEES of
both the Eastern Extension Company and the Pacific Cable Board entered the service at a
young age and continued for the rest of their working lives. Recruits were accepted at
about 15 or 16 years of age and then had to undergo a period of intensive training lasting
one or two years.
During training,
they were given books, stationery materials and tools free of charge, accommodation was
provided for those requiring it, and a small salary was paid amounting to little more than
pocket money.
Training was
rigorous and examinations were frequently held to test the boys' proficiency. Repeated
failure often meant dismissal.
On graduating as
probationary officers, the fledgling operators were presented with a copy of their
employer's rules and regulations which detailed terms of employment, mandatory life
assurance schemes, salaries and methods of obtaining promotion. Allowances for foreign
service, housing, sickness benefits, leave and payment of passages between postings were
also detailed, but many of these benefits could be withdrawn if set standards of
proficiency were not maintained or an employee's conduct did not warrant them. In
addition, elevation in rank could be denied regardless of the number of years served. Some
infringements of the rules meant instant dismissal, especially in matters of secrecy.
Insobriety and insubordination, the use of improper language or 'quarrelling on the
instrument' were not tolerated.
The companies
discouraged their younger staff from marriage even to the point of threatening to
terminate their employment if certain age, rank or salary had not been attained when the
marriage was announced.
On completing his
probationary period, an operator was liable for transfer to any of his employer's cable
stations or to serve abroad on one of the cable repair ships. Station managers maintained
a file on each employee's performance; in particular, the number of errors made by each
operator in his job.
Operators not only
had to keep up a certain speed, they also had to be accurate. if they accumulated more
than a designated percentage of errors in a month, and continued to do so, their annual
increment was not recommended. This meant a permanent loss of seniority.
Normal hours of duty
were six- or seven-hour shifts, six days a week; Sundays and certain public holidays were
paid at the overtime rate.
Operators were also
called on to perform tasks over and above the line of duty, as a crisis could occur at any
time. Men often worked to the point of exhaustion to ensure the service was not
interrupted.
But no matter how
difficult the conditions, many operators stayed with the cable service for the whole of
their working lives.
