"That doesn't mean getting thrown out of the hotel because you've got to
make passes at every beautiful girl."

"What's the matter with beautiful girls?" growled Roger. "They're
official equipment, like a radar scanner. You can't get along without
them!"

Tom and Astro looked at each other and burst out laughing.

"Come on, you jerk," said Astro, "let's get washed up. I wanta take a
walk and get something to eat. I'm hungry again!"

An hour later, showered and dressed in fresh uniforms, the _Polaris_
crew began a tour of the city. They went to the zoo and saw dinosaurs, a
tyrannosaurus, and many other monsters extinct on Earth millions of
years ago, but still breeding in the jungles of Tara. They visited the
council chamber of the Solar Alliance where delegates from the major
planets and from the larger satellites, such as Titan of Saturn,
Ganymede of Jupiter, and Luna of Earth made the laws for the
tri-planetary league. The boys walked through the long halls of the
Alliance building, looking at the great documents which had unified the
solar system.

They reverently inspected original documents of the Universal Bill of
Rights and the Solar Constitution, which guaranteed basic freedoms of
speech, press, religion, peaceful assembly and representative
government. And even brash, irrepressible Roger Manning was awestruck as
they tiptoed into the great Chamber of the Galactic Court, where the
supreme judicial body of the entire universe sat in solemn dignity.

Later, the boys visited the Plaza de Olympia--a huge fountain, filled
with water taken from the Martian Canals, the lakes of Venus and the
oceans of Earth, and ringed by a hundred large statues, each one
symbolizing a step in mankind's march through space.

But then, for the Space Cadets, came the greatest thrill of all--a trip
through the mighty Hall of Science, at once a museum of past progress
and a laboratory for the development of future wonders.

Thousands of experiments were being conducted within this crystal
palace, and as Space Cadets, the boys were allowed to witness a few of
them. They watched a project which sought to harness the solar rays more
effectively; another which aimed to create a new type of fertilizer for
Mars, so people of that planet would be able to grow their own food in
their arid deserts instead of importing it all from other worlds. Other
scientists were trying to adapt Venusian jungle plants to grow on other
planet
