How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use The General Service Code, given herewith, also called the Continental Code and the International Morse Code, is used by the Army and Navy, and for cabling and wireless telegraphy. Scouting For Girls, Official Handbook of the Girl Scouts “How can they, when wireless telegraphy has been known so long?” The Campfire Girls of Roselawn Or, a Strange Message from the Air She enquired curiously in regard to wireless telegraphy and other matters concerning ocean steamers. The Dark Star For instance, how few people could explain the principles of wireless telegraphy in a few words if suddenly questioned on the subject. Astronomy of To-day A Popular Introduction in Non-Technical Language In wireless telegraphy, to cause powerful electric oscillations in the ether. How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use It is not surprising, therefore, that wireless telegraphy should have the highest place on the list. Birdseye Views of Far Lands There were lectures on engines, aeroplanes, wireless telegraphy, meteorology, tactics, and organization. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force "The Destroyers" were responsible for our weak-kneed concessions to Berlin some years earlier, in the matter of wireless telegraphy. The Message "So," I said, "your wireless telegraphy is evidently much in advance of ours, for you seem to dispense with apparatus altogether!" To Mars via The Moon An Astronomical Story The main features of a wireless telegraphy outfit are shown in Figs.

How it Works Dealing in simple language with steam, electricity, light, heat, sound, hydraulics, optics, etc., and with their applications to apparatus in common use He invents wireless telegraphy, and the ships call to one another day and night, to tell the name of the latest winner. Appearances Being Notes of Travel By example and precept he had done all that he could before the war to adapt wireless telegraphy to the uses of the Flying Corps and to convince others of its necessity. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force The perfection of wireless telegraphy might well be followed by the gross imperfection of wires. What I Saw in America Poldhu was chosen in 1900 as the site of a station for the purpose of establishing communication by wireless telegraphy with America, Mr. Marconi being assisted at that time by Professor Fleming, of London. The Cornwall Coast He had dabbled in wireless telegraphy at school. The Submarine Hunters A Story of the Naval Patrol Work in the Great War I have not tried this theory, but the idea is fundamental to a mass of telepathic observations which have found practical expression in wireless telegraphy.

Grey Town An Australian Story In wireless telegraphy also the Receiver, perfected by Marconi, is affected by rills, made by a splash of electric discharge, over 3000 miles away. Science and the Infinite or Through a Window in the Blank Wall No need for me to mention the present day uses of wireless telegraphy and radio communication aided greatly by the inventions of others. Radio Boys Loyalty Bill Brown Listens In They had made more progress than the Military Wing in fitting wireless telegraphy and in arming aircraft. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force The instance of wireless telegraphy will serve to illustrate the difference between the two points of view. Mysticism and Logic and Other Essays The same thing has its corresponding analogy in the case of the wireless telegraphy. Genuine Mediumship or The Invisible Powers But the idea of communication with them in the future is no more audacious and no less scientific than the invention of spectral analysis, X-rays, or wireless telegraphy. Astronomy for Amateurs It may here be mentioned that there are two methods of obtaining the position of aircraft by means of wireless telegraphy, known as direction-finding and position-finding. Aviation in Peace and War More important still, wireless telegraphy plants had been set up at the various seaplane stations on the coast, and sixteen seaplanes, operating in connexion with these stations, had been fitted with transmitting apparatus. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force Science, to the ordinary reader of newspapers, is represented by a varying selection of sensational triumphs, such as wireless telegraphy and aeroplanes radio-activity and the marvels of modern alchemy. Mysticism and Logic and Other Essays If the nerve-track corresponds to wires, this refined medium may correspond to the ether-field supposed to be employed in wireless telegraphy. Genuine Mediumship or The Invisible Powers Marconi demonstrated that messages can be transmitted by wireless telegraphy, and his discovery became a thing of commercial value. Three Things It is connected with the other islands by a system of wireless telegraphy. Commercial Geography A Book for High Schools, Commercial Courses, and Business Colleges From this unit the whole wireless telegraphy organization of the Royal Flying Corps was gradually developed. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force But before it came he would polish up his forgotten knowledge of wireless telegraphy, and searched the wireless room for books. The Wreck of the Titan or, Futility At the last, it is simply a matter of "getting in tune," just as truly as in the case of the wireless telegraphy. Genuine Mediumship or The Invisible Powers But wireless telegraphy was made a commercial possibility not by any great scientist, but by a young Italian named Marconi. American Men of Mind If they had some secret form of wireless telegraphy, they may just as well have had some secret means of producing light, don't you think? There was a King in Egypt Lieutenant D. S. Lewis and Lieutenant B. T. James took every possible opportunity, during the discussions, to urge the development of wireless telegraphy. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force The constant developments in rapid transit, in the instantaneous conveniences of telephonic communication, and, latest of all, in wireless telegraphy, are all in the line of absolute correspondence with the advancing needs of humanity. The Life Radiant Now the first analogy which strikes one in the consideration of this question is that of wireless telegraphy—the subtle electric vibrations which journey to and fro with incredible swiftness through the universal ether. The Problems of Psychical Research Experiments and Theories in the Realm of the Supernormal It was our own Joseph Henry who, in 1842, discovered the electric wave—the "induction" upon which wireless telegraphy depends. American Men of Mind “You know my dad spoke about German U-boat bases along our coast, and also bases for secret wireless telegraphy plants,” put in Fred. The Rover Boys Under Canvas or The Mystery of the Wrecked Submarine The power of sending messages through space, in any direction, over great distances, is so enormous an addition to the utility of aircraft that a few words must here be said about wireless telegraphy. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force The new year of 1903 was inaugurated by the scientific success of the most remarkable, the most marvellous achievement of any age,—that of wireless telegraphy. The Life Radiant In short, telepathy is thought by many to be simply a species of physical vibration, proceeding from brain to brain, just as electric waves pass from the transmitter to the receiver in wireless telegraphy. The Problems of Psychical Research Experiments and Theories in the Realm of the Supernormal That system of wireless telegraphy which ante-dates Marconi's invention by ten thousand generations, had done effective service. Other People's Business The Romantic Career of the Practical Miss Dale Then came the day when wireless telegraphy flashed the news through the whole of the civilised world: "Stars and Stripes nailed to the North Pole." A Book of Discovery The History of the World's Exploration, From the Earliest Times to the Finding of the South Pole Further, it was found necessary for the safety of pilots that every machine should be fitted with wireless telegraphy. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force Judged, then, by their unfailing measurements, how significant was the triumphal achievement of wireless telegraphy on the eve of the dawn of 1903. The Life Radiant Thus in the case of wireless telegraphy the vibratory action of the ether is a purely mechanical process and does not carry emotion, thought, or intelligence with it—being vibration pure and simple. The Problems of Psychical Research Experiments and Theories in the Realm of the Supernormal The former are produced by the high tension electric apparatus, which we have described in the chapter relating to wireless telegraphy; and the latter, called also the Roentgen rays, are generated by the Crookes' Tube. Electricity for Boys A sergeant, two corporals and four men of the Headquarters Company Signal Platoon actually in four months time mastered the mysteries of wireless telegraphy. The History of the American Expedition Fighting the Bolsheviki Campaigning in North Russia 1918-1919 But when the German rush was beaten back, and the opposing armies were ranged along a fixed line, wireless telegraphy became a necessity for aeroplanes.

Electricity for Boys It will only be a matter of time, and that not so very far off, when wireless telegraphy will replace the telephone. Impressions of a War Correspondent So it was also with the application of wireless telegraphy to aircraft. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force This, of course, is the explanation of the phenomena involved in wireless telegraphy, and is equally the explanation of the phenomena involved in telepathy. The Life Radiant "Science is," as Bertrand Russell says, "to the ordinary reader of newspapers, represented by a varying selection of sensational triumphs, such as wireless telegraphy and aeroplanes, radio-activity, etc." Human Traits and their Social Significance When Maxwell, and, later on, Hertz, discovered that electricity, magnetism, and light were transmitted through the ether, and that they differed only in their wave lengths, they laid the foundations for wireless telegraphy. Electricity for Boys They had sent a message from heart to heart across the wide space of the plains, and the wireless telegraphy of hearts was established. The Man of the Desert No airships or aeroplanes were as yet in use in England, and all available energy had to be concentrated on producing wireless telegraphy sets for the use of the army. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force In this ethereal realm are the currents that make possible wireless telegraphy. The Life Radiant He and Sid exchanged winks and nods as though there might be a secret between them; but Fred was paying no attention to this "wireless telegraphy." Fred Fenton on the Crew or, The Young Oarsmen of Riverport School From the telephone we soon see the desirability of getting into touch with the great outside world, and wireless telegraphy absorbs our time and energies. Electricity for Boys For a time," he went on, "this drawback seemed insuperable, just as it has been in wireless telegraphy. The Best Short Stories of 1917 and the Yearbook of the American Short Story Approaching the question from the service side, he was able to do much to adapt wireless telegraphy to the new conditions presented by the conquest of the air. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force They could always communicate with Togo's flagship by wireless telegraphy. From Pole to Pole A Book for Young People Things were all very well for her before the days of wireless telegraphy, of aeroplanes and airships, of super-dreadnoughts, and cruisers with the speed of express trains. Mr. Grex of Monte Carlo Even now the application of science to the practical needs of man has some semblance of power about it; the telephone, wireless telegraphy, steam engines, anæsthetics—these are powerful things. Joyous Gard These are the waves used in wireless telegraphy, and their length may be, in some cases, measured in miles. The Outline of Science, Vol. 1 (of 4) A Plain Story Simply Told A brief history and description of wireless telegraphy. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force Ages before the day when Marconi succeeded in establishing his wireless telegraphy, the Indians of North America carried on a system of signalling by smoke rings and fire arrows. Chatterbox, 1905. The invention of aeroplanes and submarine and wireless telegraphy and the like is of no more moment than the fly on the chariot wheel, compared with the vital reconstructions which are now proceeding or imminent. Woman and Womanhood A Search for Principles He is turned into a sentient sounding-board which adds its own contribution of emotion to the music and sends it back by wireless telegraphy to the performer. The Joyful Heart Of course we are accustomed to the pious rejoinder that man must not expect to understand all the mysteries of life; and to hear vague talk about the wonder of wireless telegraphy. Applied Eugenics The ultimate appeal on the various devices, for the use by aircraft of musketry, gunnery, photography, wireless telegraphy, bomb-dropping, and signalling, must in the long run be made to the pilot. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force Why had we not made wireless telegraphy a government monopoly, instead of giving each inhabitant of the United States the right to erect an apparatus of his own if he so wished? Banzai! by Parabellum Then he got hold of a booklet about wireless telegraphy. Heart and Soul by Maveric Post Maxwell, Henry, and Hertz, equally unconcerned with material advantage, made wireless telegraphy practicable. The New Heavens But wireless telegraphy is something very definite and tangible—there is little mystery about it. Applied Eugenics The enormous value of artillery observation and the immense superiority of wireless telegraphy over all earlier and more rudimentary kinds of signalling were soon demonstrated, and the call for machines fitted with wireless became insistent. The War in the Air; Vol. 1 The Part played in the Great War by the Royal Air Force If an analogy should be made between telepathy—as we must conceive it, to explain the phenomena—and wireless telegraphy, Mrs Piper entranced must be regarded as a mere coherer of the telepathic waves. Mrs. Piper & the Society for Psychical Research He knew how the ground carried sounds more distinctly than the air, and evidently he hoped to discover something concerning the thunder by this method of wireless telegraphy. The Saddle Boys of the Rockies Lost on Thunder Mountain It was he who invented the great system of wireless telegraphy which is now used in nearly all big ships. Stories That Words Tell Us "Is wireless telegraphy a trick then?" retorted the Mahatma. Caves of Terror Steam and electricity, the cable and wireless telegraphy have overcome the intervening space and made us the close neighbors of Europe. From Isolation to Leadership, Revised A Review of American Foreign Policy But this analogy is non-existent; wireless telegraphy is far from being unaffected by distance, and besides, when the coherer functions, it is because another instrument is emitting particular waves. Mrs. Piper & the Society for Psychical Research In these days of agonizing stress she appeared as in herself the very embodiment of wireless telegraphy, aeronautic locomotion, with telepathy and divination thrown in—neither time nor space was of account. Elsie Inglis The Woman with the Torch One of the masters of practical electrical science in our time has suggested that the principle of wireless telegraphy may be extended to the transmission of messages across space from planet to planet. Other Worlds Their Nature, Possibilities and Habitability in the Light of the Latest Discoveries Only this is as far in advance of wireless telegraphy, as telegraphy is in advance of the semaphore. Caves of Terror In a word, does she, after her fashion, employ a system of wireless telegraphy? Social Life in the Insect World Remarkable results were attained by air photography from December, 1914; and after January, 1915, the regulation of artillery fire by wireless telegraphy was in general practice. Georges Guynemer Knight of the Air So is the fellow crazy who invented wireless telegraphy; so is the man off his base who invents a folding bird cage. Visionaries Another form in which the suggestion of interplanetary communication has been urged is plainly an outgrowth of the invention and surprising developments of wireless telegraphy. Other Worlds Their Nature, Possibilities and Habitability in the Light of the Latest Discoveries This system of wireless telegraphy has, however, been before described by other writers, so I need say no more about it. The Mafulu Mountain People of British New Guinea Practical physics has given us wireless telegraphy by means of the Hertzian vibrations of the ether. Social Life in the Insect World Any luminous source such as the sun, a candle flame, or an incandescent lamp is sending forth electromagnetic waves not unlike those used in wireless telegraphy excepting that they are of much shorter wave-length. Artificial Light Its Influence upon Civilization The people are equally offensive on both sides of the town; however, Podgoritza seems to be the White-chapel of Montenegro—and we finally had to take refuge in the sheds of the French wireless telegraphy. The Luck of Thirteen Wanderings and Flight through Montenegro and Serbia He has wireless telegraphy, private chemists, a little troop of spies, private telegraph and cable, and agents in every city of the world. The Black Box Then Tommy took up the subject, discussing wireless telegraphy with great confidence, but in an unscientific manner that would have brought groans of anguish from one familiar with the subject. The Meadow-Brook Girls by the Sea Or The Loss of The Lonesome Bar But they accepted the message, like a receiver in wireless telegraphy. The Disentanglers With the advent of wireless telegraphy light-signaling for long distances was temporarily eclipsed, but during the recent war it was revived and much development work was prosecuted. Artificial Light Its Influence upon Civilization She took the front seat with Jo, and inside Jan found a French sailor of the wireless telegraphy, who had had typhoid fever, but was now going back to work. The Luck of Thirteen Wanderings and Flight through Montenegro and Serbia If they are men, they exult in the thought that they can be reached by wireless telegraphy on mid-ocean. Americans and Others Bell, by his superior constructive ability, made possible the practical use of the telephone, and Marconi that of wireless telegraphy. General Science Our rapidly improving means of communication, electric trains, and, it may be, flying machines, cables, and wireless telegraphy, link lands so close together that no man lives to-day the subject of an isolated state. The Great Events by Famous Historians, Volume 01 The so-called electric waves vary in wave-length over a great range and they include those employed in wireless telegraphy. Artificial Light Its Influence upon Civilization There is, of course, a great deal of thought-vibration taking place in the world, to which the best analogy is wireless telegraphy. The Child of the Dawn In towns of from one thousand to two thousand inhabitants, the news that Mrs. X. is going to give a party spreads rapidly by that system of wireless telegraphy that excels the Marconi—neighborhood gossip. How To Write Special Feature Articles A Handbook for Reporters, Correspondents and Free-Lance Writers Who Desire to Contribute to Popular Magazines and Magazine Sections of Newspapers The Page 369new invention of wireless telegraphy, by which a ship at sea may call for aid from ashore, perhaps a thousand miles away, has great possibilities. American Merchant Ships and Sailors The telephone, the electric transmission of power, wireless telegraphy and the submarine cable are instances of immense financial returns derived from the most abstruse principles of physics. The Future of Astronomy Among recent discoveries the invention of wireless telegraphy is one of those which have rapidly become popular, and looks, as it were, an exact subject clearly marked out. The New Physics and Its Evolution The pure search for truth and knowledge was not lowered when the electrical waves were harnessed for wireless telegraphy, or the Roentgen rays were forced into the service of surgery. Psychology and Industrial Efficiency The material fruits of science are among our most familiar wonders—the motor-car, the aeroplane, wireless telegraphy. Recent Developments in European Thought In the old days, before free movement and wireless telegraphy, and before the flotilla had acquired battle power, there was always to be faced the risk of not getting contact in time to prevent mischief. Some Principles of Maritime Strategy Meatless days are to be as natural as wireless telegraphy; and the other day we were asked seriously to consider the problem of a school without teachers! Punch, or the London Charivari, Volume 152, March 7, 1917 Finally, on the 2nd June 1896, a young Italian, born in Bologna on the 25th April 1874, Guglielmo Marconi, patented a system of wireless telegraphy destined to become rapidly popular. The New Physics and Its Evolution I learned, much to my surprise, that with scarcely any knowledge of electricity the Moonites had long ago discovered a means of communication which is somewhat similar to our wireless telegraphy. Life in a Thousand Worlds It's just a thing we've invented, like—wireless telegraphy, or soap, or steam-heat; and it hands us a cloak to cover up the evil that man and woman'll never quit doing. The Man in the Twilight Firstly, the abolition of privateering; secondly, the reduced range of action for all warships; and thirdly, the development of wireless telegraphy. Some Principles of Maritime Strategy "The same sort of waves that are employed in wireless telegraphy?" asked Tom. The Boy Inventors' Radio Telephone The history of the discovery of radio-conductors is short, but it deserves, from its importance, a chapter to itself in the history of wireless telegraphy. The New Physics and Its Evolution I also learned that a very thin atmosphere is prevalent on the Moon, and that this rare medium is more suited to their wireless telegraphy than our heavier atmosphere would be with its different composition. Life in a Thousand Worlds St. George remembered in particular one young student who soberly claimed to have invented wireless telegraphy and who molested the staff for months. Romance Island A kind of wireless telegraphy seemed to have been operated by the Covenanters. Sketches of the Covenanters Just the same, only in radio telephony we are confronted by a problem not met with in wireless telegraphy. The Boy Inventors' Radio Telephone Claude Chappe incontestably effected wireless telegraphy, thanks to the luminous ether, and the learned men, such as Colonel Mangin, who perfected optical telegraphy, indirectly suggested certain improvements lately introduced into the present method. The New Physics and Its Evolution In some schools special provision is made for encouraging optional work of this kind in astronomy; in others it may be wireless telegraphy, or the use of vegetable dyes, and so forth. Cambridge Essays on Education That is the point about the wireless telegraphy or wordless telepathy of the Bedouins. The New Jerusalem I shall not pause to recount the success of my application to the astronomers to use the transmitters of the wireless telegraphy, which are as fully perfected here as at the City of Scandor. The Certainty of a Future Life in Mars "But why does radio telephony require a stronger current than wireless telegraphy?" The Boy Inventors' Radio Telephone Histories of wireless telegraphy already written, and difficulties of the subject. The New Physics and Its Evolution During the previous August a man calling himself by the name of Nelson had hired Room 46, in a building at 27 East Twenty-second Street, as a school for "wireless telegraphy." True Stories of Crime From the District Attorney's Office I remember little about wireless telegraphy; only few explanations given to me by Capt. Rescuing the Czar Two authentic Diaries arranged and translated We understand wireless telegraphy, we can bridge almost infinite distances with the monstrous waves of magnetic disturbances, it is possible for us to generate. The Certainty of a Future Life in Mars These wires formed a "ground" similar to the kind employed in aërial wireless telegraphy. The Boy Inventors' Radio Telephone The name Catwhisker harked back to the days when radio, or wireless telegraphy, was in its infancy in the experience of the three boys whose adventures are the inspiration of this volume. The Radio Boys in the Thousand Islands What relationship do wireless telegraphy and airships bear to fulfilled prophecy? The Harp of God Ten years ago wireless telegraphy was a dream of scientists; today it is the plaything of school-boys and thousands of grown-up boys as well. The Boy Mechanic: Volume 1 700 Things for Boys to Do It was then that with my son I devised, following certain suggestions, a system of wireless telegraphy. The Certainty of a Future Life in Mars This was in the early stages of wireless telegraphy, and the Madras had no installation. Witness for the Defense Cub's father had not taken his first lesson in wireless telegraphy, and so left the radio field entirely to the three young amateur experts. The Radio Boys in the Thousand Islands Students of wireless telegraphy have noticed a startling resemblance between the pineal gland and a part of the receiving instrument employed in wireless telegraphy. Clairvoyance and Occult Powers Nature needs no telephone; from time immemorial it has used wireless telegraphy in a condition of perfection unknown to man. Two Thousand Miles on an Automobile Being a Desultory Narrative of a Trip Through New England, New York, Canada, and the West, By "Chauffeur" My father, as I had said, fully intended to arrive at some definite conclusions as to the possibilities of wireless telegraphy. The Certainty of a Future Life in Mars Carty and his associates had not only developed a system which made it possible to talk across the continent without wires, but they had made it possible to combine wire and wireless telegraphy. Masters of Space Morse, Thompson, Bell, Marconi, Carty A new form of wireless telegraphy has been invented by the Post Office officials. Punch, or the London Charivari, Volume 156, May 14, 1919 The man of a generation back of the present one would have been equally justified in asserting that the marvels of wireless telegraphy were supernatural, had he been told of the possibility of their manifestation. Clairvoyance and Occult Powers Otherwise news travels only through the wireless telegraphy of bazaar gossip. Lighted to Lighten: the Hope of India Consider the telephone, the phonograph, the cinematograph, from the standpoint of space-conquest—and wireless telegraphy which sends forth messages in every direction, over sea and land. Four-Dimensional Vistas They succeeded in establishing communication without wires, using the same antenna as in wireless telegraphy, and the principles determined are those used in the wireless telephone of to-day. Masters of Space Morse, Thompson, Bell, Marconi, Carty But when the spirit to which nature comes in man has once seen the Spirit in which nature must begin, then the wireless telegraphy comes into play. The World's Great Sermons, Volume 10 Drummond to Jowett, and General Index It is a wonder that no enterprising journal has syndicated her memoirs by wireless telegraphy for the exclusive use of their Sunday issue. People of the Whirlpool Though a small instrument, and more delicate than a clinical thermometer, it loomed large in the working-out of wireless telegraphy. Stories of Inventors The Adventures of Inventors and Engineers The auxiliary cruisers must be so equipped in peace-time that when on the open sea they may assume the character of warships at a moment's notice, when ordered by wireless telegraphy to do so. Germany and the Next War Each week he expected the news that wireless telegraphy had been established, but the news never came. Masters of Space Morse, Thompson, Bell, Marconi, Carty And then a wireless telegraphy is established between them across the vast untraveled distances of nature. The World's Great Sermons, Volume 10 Drummond to Jowett, and General Index A scientific investigator should be as proud of discovering a preventive for colds as a scheme of wireless telegraphy. Punch, or the London Charivari, Volume 156, March 12, 1919 When wireless telegraphy comes into general use aboard ship the stations will doubtless be equipped with this apparatus also, so that ships may be warned of danger. Stories of Inventors The Adventures of Inventors and Engineers In 1842, he discovered, with Dr. Fisher, the principle of duplex telegraphy, and he was also the first to experiment with wireless telegraphy. Samuel F. B. Morse, His Letters and Journals In Two Volumes, Volume II With an increase in the number of wireless stations and varieties of apparatus came a wide increase in the uses to which wireless telegraphy was applied. Masters of Space Morse, Thompson, Bell, Marconi, Carty The X-ray, wireless telegraphy or the aeroplane has become the latest "marvel of science," only to develop in a very brief period into a commonplace of existence. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The capacity of the dirigible for longer flights and its superior facilities for carrying apparatus and operators for wireless telegraphy are distinct advantages. Flying Machines: construction and operation; a practical book which shows, in illustrations, working plans and text, how to build and navigate the modern airship It was the boy scarcely out of his teens who worked out the principles of his system, but it took time and many, many experiments to overcome the obstacles of long-distance wireless telegraphy. Stories of Inventors The Adventures of Inventors and Engineers In any future attempt to reach the Pole by balloon it is not unreasonable to suppose that wireless telegraphy will be put in practice to maintain communication with the base. The Dominion of the Air; the story of aerial navigation What startling developments of wireless telegraphy lie still in the future we do not know. Masters of Space Morse, Thompson, Bell, Marconi, Carty This was also invented later by another inventor, and is in use to-day, but will naturally be rivalled by wireless telegraphy. Edison, His Life and Inventions The vessel was equipped with wireless telegraphy and therewith she kept in touch with the earth below throughout the journey, dropping and picking up wireless stations as she progressed with complete facility. Aeroplanes and Dirigibles of War No news of wireless telegraphy reached the young Italian, and so he set to work at his father's farm in Bologna to develop his idea. Stories of Inventors The Adventures of Inventors and Engineers Fifteen years ago the curvature of the earth was looked upon as the one great obstacle to wireless telegraphy. Sinking of the Titanic and Great Sea Disasters It occurred to him that by their aid wireless telegraphy might be accomplished. Masters of Space Morse, Thompson, Bell, Marconi, Carty In other words, he had found the forerunner of wireless telegraphy. Edison, His Life and Inventions When the Zeppelin was finally accepted by the German Government, the military authorities emphasised the great part which wireless telegraphy was destined to play in connection with such craft. Aeroplanes and Dirigibles of War It is hard to realize that the young inventor only began his experiments in wireless telegraphy in 1895, and that it is scarcely eight years since the great idea first occurred to him. Stories of Inventors The Adventures of Inventors and Engineers "We have since found that the fog and the dull skies in the vicinity of England are exceptionally favorable for wireless telegraphy." Sinking of the Titanic and Great Sea Disasters The advantages of speaking between ship and ship as an improvement over wireless telegraphy in time of need are obvious. Masters of Space Morse, Thompson, Bell, Marconi, Carty I perfected a system of train telegraphy between stations and trains in motion whereby messages could be sent from the moving train to the central office; and this was the forerunner of wireless telegraphy. Edison, His Life and Inventions Although wireless telegraphy is available for this purpose, it suffers from certain drawbacks. Aeroplanes and Dirigibles of War Transatlantic wireless telegraphy is an everyday occurrence, and the common practical uses are almost beyond mention. Stories of Inventors The Adventures of Inventors and Engineers Some idea of the progress made may be had by citing the fact that in eleven years the range of wireless telegraphy has increased from 200 to 3000 miles.
