“I am afraid I should want to drown myself in the river if I had to live here and endure this tread-mill existence,” said Harold.

The walls of most rooms in the houses were lined with rows upon rows of books. There were schools and schools and schools; while lessons and lessons and lessons were being studied everywhere, recitations being presided over by tall, lank-looking, stoop-shouldered professors with straight, black hair, spectacled eyes, and stern visages. This constant study and grind made the children look older than their years warranted, while their heads were all too large to be supported by their poor, thin, shrunken-looking little bodies. Most children begin their studies at three years of age on this island.

“I have seen enough. Have you, Princess?” said Ione.

“Yes, and more than enough,” answered she.

Mercury now mentioned that there was a most interesting, novel part of the island called “the Black Belt,” which received this name from the color of the ring which encircles Saturn at this part. There are seven openings into this region called “The Gates of Hades.” These openings resemble the mouths of caves from which red lights shine, reflected from the inner fires.

“If you wish to visit the interior of this planet, now is your opportunity,” said Mercury. “A guide will be sent with us and will insure our safe return.”

Of course the boys were wild for this adventure but the girls were afraid to go until assured over and over again that there was absolutely no danger and that they could return whenever they wished. So at last they started in a most curious air-ship built like a bird which was named “The Sky Lark.” It could be made to fly as a bird and to alight or to arise in the air with equal ease. They all enjoyed the ride immensely, especially when they would alight on some huge tree which looked like the Banyan tree of Asia. Travelling in the air gave them a splendid chance to see all beneath them and the island looked very beautiful from this height because of its numberless bodies of water sparkling in the distance.

“Who invented this novel bird?” asked Harold.

“The most wonderful and experienced inventor that now lives,” said Mercury. “He is centuries old but by the aid of a magic liquid he keeps himself alive and he is always inventing or harnessing nature’s forces to do his bidding until there is no telling when he will stop. One of the most unique things he ever invented was an artificial elephant so like life that even live elephants themselves were deceived and thought it alive like themselves. This elephant could travel on land, in the water or on its surface, with the speed of the wind.”

“Stop, stop!” cried Harold. “What became of that elephant and its inventor?”
