his will, peer into any
apartment he wishes from his head office. The advantages of this
arrangement can be easily seen.

5. A minister can see from his study the nature of his audience before
he leaves home.

6. Farmers can watch their cattle and their fruits without leaving the
house or barn, according to where the connections are made.

7. Persons can be in bed at night, and if they imagine they hear a
robber in any room they can first turn on the photograph current and
then the light flash. In this way one can look, without leaving his bed,
into each room of the house.

Having given a few illustrations of this marvelous invention, the reader
can readily see the variety of uses which it will serve.

Their latest discovery in light is a decided improvement over our
electric light. I know of no sensible name to give it, but the name that
comes nearest to describing it, according to our terms, would be
Phosphorous Light. It gives a mild but yet positive radiance, and
closely resembles diffused sunlight.

THE AGES OF PLOID.

One of the strangest theories of the whole universe I found on this
cultured world of Ploid. They divide time into three general periods of
ages:

1. Age of Fire.

2. Temperate Age.

3. Age of Ice.

The people teach that there was a race of human beings who inhabited
their world when it was yet in a molten state and that, as their earth
cooled off, the race became extinct.

This age, they claim, was followed by the Temperate Age, or the age in
which they are now living.

It is also claimed that, when their earth cools and the frigid blasts
freeze out the world, there will gradually commence the Age of Ice, or
the age in which human species will exist by reason of the earth's stiff
coldness.

I had no way of learning the truth or falsity of this theory.

THOUGHT PHOTOGRAPHY.

These Ploidites have distanced us in the study of the nervous system,
including the intricate problems of the cerebrum and cerebellum. They
have ascertained, by long ages of observation and experimenting, the
exact effect of every kind of impulse on the brain matter. The experts
are able to tell, at a post-mortem examination, what kinds of thinking
were most prevalent during the subject's life, just as easily as we can
judge the great or little use of the arm by an examination of its
muscles.

But more wonderful, a thousand fold, is their ability to follow the
course of thought in a living cerebrum a
