A line from Calcutta to Canton is already undertaken by an English company, with due authority from the British Government.

In Australia there are now in operation twelve thousand miles of telegraph-wire. This Australian system, which is at present so purely local and isolated, is nevertheless expected to be brought into combination, by alternating submarine and island wires, with the Chinese and Russian line above described.

The statistics of the telegraph-lines in Great Britain show not only an increase in the number of lines, but a great augmentation in the amount of business transacted. In 1861 there were 11,528 miles of line open for public use; in 1862, 12,711 miles; and in 1863, 13,892 miles, comprising 65,012 miles of wire. Last year, the number of stations was augmented in like proportion; and facilities were offered for the transmission of telegraphic dispatches at no fewer than 1,755 stations, containing 6,196 instruments, through which about 3,400,000 telegrams were sent. In addition to the lines on British soil, the Submarine Telegraph Company has cables stretching to Calais, Boulogne, Dieppe, Jersey, Ostend, Hanover, and Denmark, with which the other lines are more or less in connection, covering 887 miles with 2,683 miles of wire. This company has upwards of 3,000 stations on the Continent. The messages sent by it to and from foreign countries were, in 1861, 230,000; in 1862, 310,595; and in 1863, 345,784.

France possesses a system comprising 71,034 miles of wire and 1,301 stations, which transmit about 1,500,000 private dispatches annually, and nearly 175,000 official ones. Russia has 36,663 miles of wire; Austria, 22,230; Italy, 20,120; Prussia, 24,149; Spain, 17,743; Belgium, 3,773; Switzerland, 3,720; Turkey, 6,571; Persia, 2,500; Greece, 3,000; India, 10,994, and 136 stations; Australia, 12,000; South Australia, 2,000; the United States, 120,000; the British Provinces in America, 20,000;—making a total of upwards of 440,000 miles of aërial wire in operation in all parts of the world.


The following tables give the details of the principal cables hitherto laid by all makers. They are divided into three heads: 1st, Those which have been wholly successful, and are now working (September, 1865); 2d, Those which were partially successful, having worked for a time; 3d, Those which wholly failed, or never worked after their submergence.
