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 height or length. It
is certainly thrilling to step into a world where all things are so
gigantic. At times a feeling of insignificance crept over me, but I took
courage when I thought that a man's greatness consists in his mental
powers and not in his physical bulk, for it is true that the fifty
ounces of brain in the skull of a Newton have accomplished more marvels
than the ten pounds of brain-matter found in the most cultured
Jupiterite.

We must give the people of Jupiter credit for exercising a large amount
of common sense. In many ways they are more practical than we, and this
