At Harvard and Mare Island the radio students are put through four months' courses, which embraces not only radio-telegraphy and allied subjects, but military training. Some 500,000 men have been undergoing courses at these two schools alone.
Your ranger told us this morning that if he found a fire he couldn't handle, he would have to go clear out to the highway before he could summon help. With the wireless, help could be summoned almost instantly." The forester smiled indulgently. "It sounds good," he commented. "But you forget that we have no wireless and that none of us knows anything about radio-telegraphy.
In 1901 wireless telegraphic messages were sent across the ocean, and within a few years private and press notices were being sent across the Atlantic, vessels were commonly equipped with instruments, and international regulations concerning radio-telegraphy were adopted by the chief powers of the world.
"But still, full credit must be given where credit is due, and in that respect it must be acknowledged that Marconi only assembled and perfected to practicable purposes the discoveries and inventions made before his time. "Radio-telegraphy might be briefly traced in the names of Faraday, Maxwell, Hertz the discoverer of the Hertzian rays Righi, Lodge and Marconi.
With the need of operators apparent, a school for preliminary training in radio-telegraphy was established in each naval district, and when the need for a central final training-school developed, Harvard University offered the use of buildings, laboratories, and dormitories for this purpose.
When the evening was farther advanced, and the air was vibrant with the voices of the wireless, Lew and Charley took turns reading the news, while the ranger's expression of amazement and admiration grew deeper and deeper, and his liking and respect for his young subordinate increased rapidly. Finally the ranger was given his first lesson in radio-telegraphy.
When Hertz discovered that electric waves crossed space he unconsciously became the father of the modern system of radio-telegraphy, and though he did not live to put or see any practical results from his wonderful discovery, to him in a large measure should be accorded the honor of blazoning the way for many of the intellectual giants who came after him.
Of course the forester knew about radio-telegraphy, but he was like many other people who have not actually seen persons talk by wireless. It seemed as though it could hardly be. But he was not to remain long in doubt. When the three-minute period had elapsed, Charley threw over his switch, and sent Willie's call signal flashing abroad.
