Vessels in these days of the nineteenth century only too often left port never again [A Very Backward Age.] to be seen by mortal man. Loved ones plunged into a watery grave, locked in each other's embrace, and none survived to tell the fearful tale. Communication with shore was unknown in the vaunted civilization of the nineteenth century. The fate of the Naronic, of the White Star line, looms up in evidence. Not a whisper was again heard of her after she left port. The City of Glasgow in 1854 sank in Neptune's pastures. Four hundred and eighty souls went down in that brave ship. No hint, however slight, was ever heard of her. The Ocean Monarch, the Pacific of the Collins line, and the ill-fated City of Boston, all suffered fates that none but the day of judgment can reveal. This confession of weakness, this serious drawback of the nineteenth century, which added to the terrors of those "who go down into the great deep," was fortunately not shared by the advanced sciences and arts of the twentieth century. Wireless telegraphy contributed almost as much to the comfort of ocean and ærial navigation as electricity. Telegraph poles that rendered hideous some of our most beautiful avenues and the antiquated ocean cables were entirely relegated into oblivion. The former went into the scrap heap, while the latter found their way into Davy Jones' locker. Long before 1999 wireless telegraphy was employed on all vessels on ocean, river and lake. Instant communication was at all times maintained between ship and shore. [It Opened a New Era.] War vessels at foreign stations made their daily reports in 1999 to the Navy Department in the State of Mexico. All other navies of the world enjoyed the same facilities. Relatives telegraphed to their families and friends from vessels in mid-ocean. It was quite common to receive a brief message from an Atlantic liner two thousand miles east of Sandy Hook, as follows: On board Electrical Ship Manhattan. } Latitude 50 N., long. 30 W. } Dear Henry:--Got over being seasick. Baby and nurse doing nicely. Had strawberries and cream for dinner. Dodged an iceberg and struck a whale, yesterday. Love to all. Will wireless from Paris. Ethel. Overdue vessels in 1999 gave no anxiety in that era of progress. If a shaft broke the home office was at once notified that the vessel would be several days behind her schedule time in arriving at her destination. If caught in a fog or obliged to move at half speed, the information was immediately lodged on shore. In fact it even became possible to navigate vessels from the shore.
