| Show WHAT HATH GOD WROUGHT A young scientist of boston named C E dolbear has been at work for some time on a scheme for the practical application of the theory of wireless telegraphy he has succeeded in carrying his plans to so successful a stage that he felt justified in asking recently for assistance to enable him to make a practical demonstration of his wonderful invention this was furnished him by the new york world which placed a tug and assistants at the inventors disposal the experiment was a very interesting one not only because of the immediate developments but because of the new era em in this department of science fore shadowed by it the result of the test is thus spoken of by that paper in a necessarily limited distance messages were clearly read on the world tug sent by operators on shore who depended wholly upon n the radiation of an interrupted submerged electric current thus the theory was demonstrated in practice and it remains for the specialists to perform the working of the system until our ships can communicate with each other or the shore at a distance of fifty or more miles to do this for the benefit of our navy was of course the mo tive which prompted the world ia making the demonstration possible it will be remembered that when after a wearying but ceaseless struggle with congress S F B morse succeeded in obtaining assistance for the construction of a line of telegraph from washington to baltimore he used two wires to make the electrical electric aJ circuit later the inspiration entered the mind of man that two wires were not needed that by putting the th ends in the r arth it would fill the place of one of the wires which it subsequently has done after a 9 while when edison entered the arena and began playing the iconoclast with some of the old time theories and practices he showed in a practical way that it was a waste of time and money to let a wire be used but one way at a time and caused it to work both ways at once then he invented the quadra qu adru plex by means of which two mess messages agest could be sent simultaneously over thel ame wire in the same direction ana two more in the opposite direction it looks as if such afield a field for scientific ex ek were limitless and we are now apparently at the threshold of a condition of things in which wire and other othea electrical conduits will be dispensed with altogether and of course the end will not be then people of this generation know a good glod deal more than those of the pre art 1 ceding one knew and those follo following us will know more than we do thle this is the manifest tendency of the humane human family the first message sent over morses line was what hath god goca I 1 wrought in contemplating the gradual evolution of morses discovery s and its status at this time one Is justified in answering only a small part cf what he has since wrought and to Is continuing to bring about through the agency of his children peace hath indeed her triumphs which axe are not only not inferior to those of war but of 0 vastly more useful consequence to our race |
