The marvelous construction shown in the accompanying cut is part of a great scheme by which the electrician, Nikola Tesla, says he will have in operation before a great while and which he calls “world telegraphy.”

From this tower, which he has been building at Wardenclyffe, on Long Island, for some time, and which he has recently completed, he hopes to send and recieve messages from all over the world irrespective of distance or intervening obstacles. The construction of the upper part of this tower is said to be so delicate that it will detect the slightest impulses that come to it through the air. He says that he will be able to deliver the electrical current anywhere and in any amount by the use of certain artifices which he has discovered and which he will make known in due course.
