Ten minutes after eleven—why that would be only ten minutes after six in New York! How plainly he could picture the familiar scenes of rushing, bustling life back there! Crowds were now pouring into the subways and surface cars or climbing to the level of the "L's." This was the third—the latest homeward wave. The five o'clock people had, for the most part, already reached their homes and were thinking about their dinner; the five-thirties were well upon their way.

How the millions of his native city and of other cities and towns, and even of the country districts, all moved upon schedule! Clocks and watches told them when to get up, when to eat their breakfasts, when to catch their trains, reach their work, eat their lunches, and return to their homes. Newspapers came out at certain hours; mails were delivered at definite moments; stores and mills and factories all began their work at specified times.

What a tremendous activity there was, back there in America, and how smoothly it all ran—smooth as clock-work! Why, you might almost say it ran by clock-work! The millions of watches in millions of pockets, the millions of clocks on millions of walls, all running steadily together—these were what kept the complicated machinery of modern life from getting tangled and confused.

Yes; but what did people do before they had such timepieces? Back in the very beginning, before they had invented or manufactured anything—far back in the days of the caveman—even those people must have had some method of telling time.

A bright star drew above the shadowy outline of a hill. At first the man in khaki thought that it might be a distant star-shell; but no, it was too steady and too still. Ah yes, the stars were there, even in the very beginning—and the moon and the sun, they were as regular then as now; perhaps these were the timepieces of his earliest ancestors.

A slight rustle of anticipation stirred through the waiting line and his thoughts flashed back to the present. His eyes fixed themselves again on the ghostly splinters of light at his wrist. The long hand had almost reached the figure 4—the moment when the bombardment would begin.

He and his comrades braced themselves—and the night was shattered by the crash of artillery.
