“Eli Terry did, in the year 1809,” said Somebody, “and after a time he got Seth Thomas to help him. As soon as people realized what a very great convenience it was to be able to keep accurate time, nobody wanted to be without a clock. And then people began to travel more and needed to have something portable with which to tell time, and so the convenient watches came to be made.

“‘What time is it?’ you ask. Centuries of scientific progress, with vast labor and years of patient study, have been necessary to answer that question. You’ll find that men had to delve into mathematics, the mysteries of astronomy, the wonders of physics and chemistry, before they could force the hands on the dial to tell you when to start for school or to catch your train. As you look at a clock, remember that every time the minute-hand passes from one of its marks to the next, it shows that this huge globe on which we live has covered more than 1,000 miles of its headlong journey.

“And then along came Madame Curie, the brilliant French scientist, and discovered radium, the merest shadow of which makes the dial of your watch luminous for as long as it lasts.

“There is a very famous clock in Strasbourg which not only tells the time of day, but also the day of week, the month, and the position of the moon and the planets. At various times processions of tiny figures cross a stage, including a cock that crows. The day of week is indicated by a separate little figure which takes its place on a tiny platform.

“A watch is perhaps the most wonderful little machine in the world. Packed in a case sometimes no bigger than a twenty-five cent piece and less than a quarter of an inch thick are from one hundred and fifty to eight hundred separate parts. And there you are, Billy Boy!”

“Time for bed,” said Mother. “And don’t linger too long admiring your new watch or it will be time to get up.”

“Goodnight everybody, and Somebody,” said the boy named Billy, “and thanks again, Mom, for the watch. I’ve never before had such a jimdandy birthday gift.”
