t but not luminous. It has cooled sufficiently to admit human
forms, although certain parts of the giant planet are void of all life,
owing to the more intense heat in those sections.

The atmosphere is charged with thick clouds, never at rest and
continually forming into immense scrolls close to the surface of the
planet.

The human life of Jupiter is found in certain belts where the crust of
the planet has been hardened for several thousand years. The people have
risen from rude, primitive conditions to a state of splendid
civilization. In size they are colossal giants, averaging twenty-five
feet in height. Their two powerful arms extend from what we would call
the hips, and no one would imagine with what facility these giants use
them. After extended observation, I was almost tempted to wonder why our
arms were placed so high on the body. These Jupiterites are more
handsome than the people on the Moon or Mars, and their faces shine with
a superior intelligence. Instead of hair on the head, they have
something unknown to our world, quite similar in appearance to wool.

Their two eyes blaze like balls of fire, making one of the giants appear
like a fiersome though not repulsive monster. The most unusual feature
about the face is the peculiarity of the chin and forehead. Each is
covered with convolutions of an insensible, rubber-like membrane.

The people of Jupiter excel in mechanical skill. They build houses, but
not by long, tedious days of painstaking labor. Such things as plaster
and paint are unknown. A Jupiterite can purchase, from one of the
mammoth structural factories, house sides, house ends, house floors or
partitions, after any general design he wishes, and have them trimmed in
any style his fancy suggests. The materials used are non-combustible and
water-proof, and will wear indefinitely.

These houses can be put together in a few days and the trimmings
adjusted in less than two weeks, unless the structure is very elaborate.
Nearly all of their house furniture is also non-combustible, and no one
has ever conceived the idea of forming a fire insurance company, simply
because there is no need for one.

As the people are so much larger than we, so are all things relatively
larger than we see them in our world. Wagons and carriages and cars
appear as if they were made for mastodons.

I saw one of their largest bridges spanning a molten lake. Aside of it
the East River bridge would be a dwarf, either in
