 Few persons who have not made a
 study of wireless telegraphy realize
 that 1t can be anything but a com
 plicated science with no end of mys-
 tory. The very thought of transmit
 ting any form of message through
 space so that 1t will be intelligible to
 persons at great distances, and all
 this without any visible means of
 connection between the two points,
 taxes human credulity almost to the
 breaking point. As matter of fact
 wireless telegraphy in it's fundamen-
 tai principles is so simple that one may we'll marvel why it was not dis covered prior to the announcement of s. F. B. Morse that he has solved the puzzle of telegraphic communi- cation with a wire. If we search the records of the scientists, We find that wireless telegraphy was really dis covered in principle nearly two cen turies ago, but, as in the case of many another invention, the inven- tor himself had no comprehension of the practical possibilities of his dis covery Even after Signor Marconi, the accredited inventor of wireless telegraphy because he was the first to give the subject a practical, com application, had been work ing so successfully that he could transmit wireless signals upward of three miles, he had to have the com brought forcibly to his notice by hard headed business men before he could look upon it in any other light than that of a scientific achievement.
 Wireless telegraphy is simple be- cause it merely initiates nature and does little more than harness the natural forces which have been a part of our daily life since the crea- ton of the universe. Every one knows what air is in the abstract. IF fact. every particle of air may be further subdivided into particles cf ether which are so minute that no scientific instrument can measure them. If we liken large glass ball | to a particle of air, the fine bird | shot with which it might be filled | would represent the particles of | ether which go to make up particle of air. The ether in the air is in constant motion. Heat and sunlight | are nothing more nor less than ether | waves set in motion by the great | generator, the sun. The waves thus | generated move as the surface waters | )f the ocean when rolling along after | I storm. They are always of fixed | ength and travel at the rate of lS6, 1000 miles a second. Wireless
 elegraphy, through its sending in 'trument, simply forces into the ether a sudden, additional volume of electricity which sets a series of | ether waves fin motion just as if generated by the sun. They travel ,n and on at the same tremendous
 peed as the suns ether waves. Along
 heir course, for they move in all directions from the sending point as
 he waves leave a stone thrown into l pond, they come in contact with
 he wire erected above the wireless 'eceiving station. The ether wave impulse passes down the wire and so tets on the sensitive receiving in-
 trument as to produce a sound. It s a simple matter to take the next
 tep and send the waves, as the i'm pulses are sent over a telegraph line n the form of long and short i'm pulses called dots and dashes, in q manner so that they constitute pre-
 rranged signals which can be ransposed into the letters of the
 lbhabet and spell words.
 In general way, that is all there B to wireless telegraphy. When it anne to work out the details. 1t was
 10 simple task. Endless experiments

( With that accomplished. a similar , cries of difficult problems had to be ; olved in the case of the receiving 1 In view of the fact I hat the discovery of wireless teleg- ( aphy in its practical form only dates q rom 1900, one can not but marve! 1 [ the progress made by Signor Mar { oni whose system can now transmit |, nfailingly any message for distances ( pward of 2,000 miles and whose I ltest experiments are convincing roof that he will shortly bridge the cean with a service that will meet II the demands placed upon { for a continuous and per l set method of transmitting I lectrical impulses.
