Time, as we know it, is a very recent invention. The modem time- sense is hardly older than the United States. It is a by-product of industrialism —a sort of psychological analogy of synthetic perfumes and aniline 67. ______ dyes. Time is our tyrant. We are chronologically aware of the moving minute 68. ______ hand, even of the moving second hand. We have to be. There are trains to be caught, tasks to be done in specified period, re- cords to be broken by factions of a second, machines that set the pace and 69. ______ have to be kept up with. Our consciousness of the smallest units of time is now big. To us, for example, the moment 8:17 A.M. means something— 70. ______ something very important, if happens to be the starting time of our daily 71. ______ train. To our ancestors, such an odd eccentric instant was with significance 72. ______ —did not even exist. In inventing the locomotive, Watt and Steven- son were part inventors of time.

Result: the factory worker is compelled to know 75. ______ time in its smallest fractions. In the hand-work age there was no such a 76. ______ compulsion to be aware of minutes and seconds.
