in the same position as the Romans of two thousand years ago, dependent
upon the horse as his swiftest mode of progress. With the automobile we
have suddenly doubled, quadrupled the size of our "neighborhood," the
space which a man may cover alone at will for a ramble or a call. As
for speed, we seem to have succumbed to an actual mania for
ever-increasing motion. The automobile is at present the champion
speed-maker, the fastest means of propelling himself man has yet
invented. But the aeroplane and the hydroplane are not far behind, and
even the electric locomotive has a thrill of promise for the speed
maniac.[2]

In thus developing his mastery over Nature man sometimes forgets his
danger, oversteps the narrow margin of safety he has left between
himself and the baffled forces of his ancient tyrants, Fire and Water,
Earth and Air. Then indeed, in his moments of weakness, the primordial
forces turn upon him and he becomes subject to tragic and terrific
punishment. Of such character was the most prominent disaster of these
years, the sinking of the ocean steamer _Titanic_. The best talent of
England and America had united to produce this monster ship, which was
hailed as the last, the biggest, the most perfect thing man could do in
shipbuilding. It was pronounced "unsinkable." Its captain was reckless
in his confidence; and Nature reached down in menace from the regions
of northern ice; and the ship perished.[1] Since then another great
ship has sunk, under almost similar conditions, and with almost equal
loss of life.
