In the first chapter I mentioned the superior imaginativeness revealed by Americans in meeting linguistic emergencies, whereby, for example, in seeking names for new objects introduced by the building of railroads, they surpassed the English /plough/ and /crossing-plate/ with /cow-catcher/ and /frog/. That was in the 30's. Already at that early day the two languages were so differentiated that they produced wholly distinct railroad nomenclatures. Such commonplace American terms as /box-car/, /caboose/, /air-line/ and /ticket-agent/ are still quite unknown in England. So are /freight-car/, /flagman/, /towerman/, /switch/, /switching-engine/, /switch-yard/, /switchman/, /track-walker/, /engineer/, /baggage-room/, /baggage-check/, /baggage-smasher/, /accommodation-train/, /baggage-master/, /conductor/, /express-car/, /flat-car/, /hand-car/, /way-bill/, /expressman/, /express-office/, /fast-freight/, /wrecking-crew/, /jerk-water/, /commutation-ticket/, /commuter/, /round-trip/, /mileage-book/, /ticket-scalper/, /depot/, /limited/, /hot-box/, iron-horse, /stop-over/, /tie/, /rail/, /fish-plate/, /run/, /train-boy/, /chair-car/, /club-car/, /diner/, /sleeper/, /bumpers/, /mail-clerk/, /passenger-coach/, /day-coach/, /excursionist/, [Pg083] /excursion-train/, /railroad-man/, /ticket-office/, /truck/ and /right-of-way/, not to mention the verbs, /to flag/, /to derail/, /to express/, /to dead-head/, /to side-swipe/, /to stop-over/, /to fire/ (/i. e./, a locomotive), /to switch/, /to side-track/, /to railroad/, /to commute/, /to telescope/ and /to clear the track/. These terms are in constant use in America; their meaning is familiar to all Americans; many of them have given the language everyday figures of speech.[22] But the majority of them would puzzle an Englishman, just as the English /luggage-van/, /permanent-way/, /goods-waggon/, /guard/, /carrier/, /booking-office/, /return-ticket/, /railway-rug/, /R. S. O./ (railway sub-office), /tripper/, /line/, /points/, /shunt/, /metals/ and /bogie/ would puzzle the average untravelled American.
