Many years ago an ocean steamship
made only ten or twelve revolutions of
the engine, using only five pounds OF
steam pressure. With this she averaged
about eight knots. High-powered ships
of the present day use thirty-six times
this pressure and make seven times the
revolutions. Their, speed is only two and
half times as great.
