Again, in 1898, on the occasion of California's Golden Jubilee, that is, her semi-centennial celebration of the discovery of gold in the state, William McKinley, then president of the United States, seated in his office at the White House, in Washington, D. C., pressed an electric button which rang a bell in the Mechanic's Pavilion in San Francisco, and formally opened the mining exposition, though the president was distant about three thousand miles! The press dispatches, at the time of the advent, gave the following graphic description of the event just related: By an electric sensation, as indescribable as the thrill of the discoverer's cry of "gold," the president of the nation sent from Washington the signal which announced the opening of the fair. As the bell clanged its clear note, and the Great West was for an instant connected with the distant East, a hush fell on the gathered thousands; then, moved by a common impulse, the vast throng burst into cheers. Close following on the touch which sounded the sweet-toned bell came the greeting of President McKinley, announcing "the marking of a mighty epoch in the history of California." About him, over three thousand miles away, stood the representatives of the state in Congress, their thoughts flying quicker even than telegraphic message to the people gathered in the great pavilion. And so, united by the material ties of the electric wire, and the subtle powers of thought, the East and the West were held for a few brief moments by a community of good wishes. Wonderful as all this is, it is now eclipsed by wireless telegraphy--now passed beyond its experimental stages, and rapidly coming into the practical commerce of the nations. Man is no longer dependent upon a network of wires and cables for means of communication. The atmosphere enveloping the world affords sufficient means for conducting vibrations made intelligible by the instrument of man's invention; and today, even across the surface of the broad Atlantic, messages are transmitted by this means as easily as by means of the cable lines. So delicate and perfect are the receiving instruments, that from the roar of our great cities' traffic, the message is picked out of the confusion and faithfully registered.
