[HOW TO MAKE A SUN-DIAL]
Did you ever think how hard it would be to get along without clocks? At almost every city street corner we can look at a clock; every railway station, every post office, every schoolhouse, has at least one; and everybody's house contains one or more. And at that, boys and girls are sometimes late for school.
No, we certainly couldn't manage without these useful mechanisms; and yet, there was a time, not so many centuries ago, either, when they were a rare possession; and a time before that when they had not yet been invented. What did our far-off ancestors do?
Let us pretend that we are going for a walk in the beautiful garden of a country mansion. Here in the midst of a rose bed stands a low stone pillar, with an upright, triangular piece of metal attached to its top near the center, and some figures marked in a circle around the edge.
This is a sun-dial. The owner of the garden has it here for a pretty ornament; but in the old times, before the days of clocks, people told the time by means of sun-dials, judging the hour by the position of the shadow cast by the piece of metal upon the stone. If you would like, just for the fun of it, to have such a sun-clock in your own little garden, there is a very easy way to make one.
