Seite 193 - What can be more palpably absurd and ridiculous than the prospect held out of locomotives travelling twice as fast as stage-coaches! We would as soon expect the people of Woolwich to suffer themselves to be fired off upon one of Congreve's ricochet rockets, as trust themselves to the mercy of such a machine going at such a rate.
Seite 303 - ... comes the potent agency of steam. In comparison with the past, what centuries of improvement has this single agent comprised, in the short compass of fifty years ! Everywhere practicable, everywhere efficient, it has an arm a thousand times stronger than that of Hercules, and to which human ingenuity is capable of fitting a thousand times as many hands as belonged to Briareus.
