A TELEGRAPH OPERATOR'S LIFE 



Experiences and Adventures as Operator and Train-Despatcher 



Captain Jasper E. Brady, now of the Army, began life as a telegraph 

 operator. He served in commercial and railway offices in about all parts 

 of the country and under all possible conditions. He passed through all the 

 grades up to that of chief train-despatcher ; and since he entered the Army 

 he has been detailed to many special services where his experience with the 

 telegraph and railroads would be particularly useful. These chapters are 

 a Series of Choice Stories from Captain Brady"s own experience, illustrating 

 the telegraph operator's life in about all the curious conditions that ever fall 

 to his lot. . 



INVENTION AND SCIENCE 



THE TELECTROSCOPE AND ITS INVENTOR 



Mr. Cleveland Moffett has lately returned from a visit to the young Polish 

 inventor, Jan Szczepanik, to examine his wonderful invention that transmits 

 a whole picture by telegraph so that it comes out to a beholder miles away 

 complete, and even in the natural colors of the object or scene portrayed; and 

 in an article soon to appear he gives an interesting account of the inventor 

 and of his invention. The article will be fully illustrated. 



A PLUNGE IN THE DIVING TORPEDO BOAT 



An article by Franklin Matthews describes his own strange experience in 

 going down under the sea in the new submarine torpedo boat, the " Holland." 

 The article also describes the curious construction of the boat. She is, undoubt- 

 edly, one of the most remarkable products of the mechanical ingenuity of man. 



SUBMARINE NAVIGATION 



By SIMON LAKE 



Mr. Lake, inventor of the Lake Submarine Boat, has prepared an interest- 

 ing article on his successful cruises on the bottom of the sea. He has traveled 

 on the bottom of the sea over 1,200 miles all told, and has made the first 

 practical submarine boat. It has remained submerged for ten hours, and from 

 it, while at the bottom of Chesapeake Bay, telephone communications were 

 carried on with Washington, Baltimore, and New York. 



TELEGRAPHING WITHOUT WIRES 



This continues to be the special goal on which electrical experts are con- 

 centrating their thoughts and labors. We hope to publish in the coming 

 months some very interesting matter on the subject, especially from Mr. W. 

 H. Preece, Engineer-in-Chief of the Telegraph Department of the English 

 Postal System, on the latest experiments of the British postal authorities. 



THE MARVELS OF THE SEA 



This is an account of the zoological station at Naples, where all the 

 animal and vegetable growths of the Mediterranean Sea have been gathered, 

 still living, and to which advanced students from all parts of the world resort 

 to study these growths, as it were, " in a great and beautiful book of living 

 Nature." The article will be fully illustrated, and will be one of the most 

 interesting of the kind that we have ever published. 



UNSOLVED PROBLEMS OF ASTRONOMY 



By SIMON NEWCOMB 



This is the title of a remarkable article by one of the most eminent of 

 living astronomers. Another article by Professor Newcomb, combining the 

 same popular and readable qualities with the latest and most authoritative 

 information, is, " How Planets are Weighed."
