photographed on paper. So every object about us is photographed on the
rays of light and the picture becomes visible when we turn our eye,
which is a small but perfect camera, so that the rays of light can go
straight into our eye and the picture fall upon the back of the eye,
which is called the retina, and with which this glass in the camera
corresponds.

An ordinary looking-glass will demonstrate or show the same thing. This
covering on the back of the glass corresponds to the black cloth with
which the photographer shuts out the rays of light which come from the
back of the camera. In the same way the ground at the bottom of the pond
cuts off the rays from beneath, and on this account you can see the
hills, or stars, or clouds reflected in the water; so also in the
looking-glass, as you turn it in different directions you can see the
photographs of persons or objects which are pictured upon the rays of
light.

You may have thought that you saw the person or objects themselves, but
this is not the case. With your eyes you can see nothing in the dark;
even the cat and the owl must have some light, although they do not need
as much as we, before they can see. The rays of light carry the pictures
of the objects, and where there are no rays of light we can see
nothing.

Now, while your photograph is being taken from the few rays of light
which pass into a camera, you see that we might place hundreds of
cameras one above another, and if they were all pointed at you they
might each take a photograph of you at the same instant--the same as one
thousand different persons in an audience with their two thousand eyes
all look toward the speaker and see him at one and the same instant.

Now, if I have succeeded in making my thought plain, you will readily
understand that as we have great books with pictures upon every page, so
God might use these rays of light as the pages of the great book upon
which each act of our life instantly records itself, it matters not how
rapidly it is done or how many persons and objects there may be in
motion or action at the same instant. The fact that the different rays
of light carry the pictures of the objects from which they are
reflected, is illustrated in the wonderful cameras with which "moving
pictures" are taken.

To older persons I might add that if you recall the scientific fact that
these rays of light, bearing the images or photographs of persons and
objects from which they are r
