The details of the voyage they took in the Flying Mermaid, are told of in the third volume, entitled “Five
Thousand Miles Underground.” The Mermaid could sail on the water, or float in the air like a balloon. In this
craft the travellers descended into the centre of the earth, and had many wonderful adventures. They nearly
lost their lives, and had to escape, after running through danger of the spouting water, leaving their craft
behind.
For some time they undertook no further voyages, and the two boys, who lived with Professor Henderson in a
small town on the coast of Maine, were sent to attend the Universal Electrical and Chemical College.
Washington remained at home to minister to the wants of the old professor, and Andy Sudds went off on
occasional hunting trips.
But the spirit of adventure was still strong in the hearts of the boys and the professor. One day, in the midst of
some risky experiments at college, Jack and Mark, as related in “Through Space to Mars,” received a telegram
from Professor Henderson, calling them home.
There they found their friend entertaining as a guest Professor Santell Roumann, who was almost as
celebrated as was Mr. Henderson, in the matter of inventions.
Professor Roumann made a strange proposition. He said if the old scientist and his young friends would build
the proper kind of a projectile, they could make a trip to the planet Mars, by means of a wonderful motor,
operated by a power called Etherium, of which Mr. Roumann held the secret.
After some discussion, the projectile, called the Annihilator, from the fact that it annihilated space, was begun.
It was two hundred feet long, ten feet in diameter in the middle, and shaped like a cigar. It consisted of a
double shell of strong metal, with a non−conducting gas between the two sides.
Within it were various machines, besides the Etherium motor, which would send the projectile along at the
rate of one hundred miles a second. This great speed was necessary in order to reach the planet Mars, which,
at the time our friends started for it, was about thirty−five millions of miles away from this earth. It has since
receded some distance farther than this.
Finally all was in readiness for the start to Mars. Professor Roumann wanted to prove that the planet was
inhabited, and he also wanted to get some of a peculiar substance, which he believed gave the planet its rosy
hue. He had an idea that it would prove of great value.
But, though every precaution was taken, the adventurers were not to get away from the earth safely. Almost at
the last minute, a crazy machinist, named Fred Axtell, who was refused work on the projectile, tried to blow it
up with a bomb. He partly succeeded, but the damage was repaired, and the start made.
Inside the projectile our friends shut themselves up, and the powerful motors were started. Off it shot, at the
rate of one hundred miles a second, but the travellers were as comfortable as in a Pullman car. They had
plenty to eat and drink, they manufactured their own air and water, and they slept when they so desired.
But Axtell, the crazy machinist, had hidden himself aboard, and, in mid−air, he tried to wreck the projectile.
He was caught, and locked up in a spare room, but, when Mars was reached, he escaped.
The book tells how our friends were welcomed by the Martians, how they learned the language, saw many
strange sights, and finally got on the track of the Cardite, or red substance, which the German professor, Mr.
Roumann, had come so far to seek. This Cardite was capable of great force, and, properly controlled, could
move great weights and operate powerful machinery.
