THE PHONOGRAPH.

BOOKS THAT TALK.

SUGGESTION:--Object: A small tin box, with a cover
and bottom removed. Over one end draw and tie a
piece of parchment, or even of strong manilla
paper, in the center of the miniature drum-head
thus formed fasten a thin string, and you will
then have a rude but real telephone and a good
representation also of the phonograph.

LAST Sunday I talked to you about the great Judgment Day and tried to
illustrate to your minds what is said in Revelation, twentieth chapter,
twelfth verse, where it says, "The dead were judged out of those things
which were written in the books, according to their works." I tried then
to make plain how God pictures or photographs all our acts upon the rays
of light, and how we see the objects about us when the rays of light
fall upon the retina of the eye. I tried to show you how every ray of
light carries a photograph or picture, and that these rays of light are
sweeping out into space at the rate of 192,000 miles per second, and
that if you and I could be present where these rays, carrying the
picture of the battle of Bunker Hill are now hurrying through space, you
could see the battle, as if it were taking place at present. If you had
a camera with you, you could actually take a photograph of it, the same
as you could have done had you been on the hills outside of Boston on
the day when this great battle was being fought.

But that is only one book; God has other books also. But you know you
can not photograph what a person says. So I want to try and show you how
our words and all we say also go into a great book and write themselves
down, so as to become permanent for all time.

Now, I have here a baking-powder box, from which I have removed the
ends, and in place of the tin have covered it with a stout piece of
paper which I have tried to draw very smoothly. With two such boxes,
connected by a string, we could make a telephone so that we could talk
together a short distance. Or with only one box we could construct a
very rude but yet very suggestive phonograph.

Let me tell you how it is that you can hear over the telephone, whether
made of a simple box and string like this, or with a wire and electric
battery, for in one respect they are both alike.

If you will place your finger gently on your throat, against what is
sometimes called "Adam's Apple," but what is really the de
