To-day the telegraph is the great nerve system of the nation’s body, and it ramifies and vitalizes every part with sensitive force. In 1899 the Western Union Telegraph Company alone had 22,285 offices, 904,633 miles of wire, sent 61,398,157 messages, received in money $23,954,312, and enjoyed a profit of $5,868,733. Add to this the business of the Postal Telegraph Company and other companies, and it becomes well nigh impossible to grasp the magnitude of this tremendous factor of Nineteenth Century progress. Figures fail to become impressive after they reach the higher denominations, and it may not add much to either the reader’s conception or his knowledge to say that the statistics for the _whole world_ for the year 1898 show: 103,832 telegraph offices, 2,989,803 miles of wire, and 365,453,526 messages sent during that year. This wire would extend around the earth about 120 times, and the messages amounted to one million a day for every day in that year. This is for land telegraphs only, and does not include cable messages. What saving has accrued to the world in the matter of time, and what development in values in the various departments of life, and what contributions to human comfort and happiness the telegraph has brought about, is beyond human estimate, and is too impressive a thought for speculation.
