EN FROM ULLER

As seen from the north pole--no sun is visible on Jan. 1. On April 1,
it bisects the horizon all day, swinging completely around. April 1 to
July 1, it continues swinging around, gradually rising in the sky, the
spiral converging to its center at the zenith, which it reaches July
1. From July 1 to October 1 the spiral starts again, spreading out
from the center until on October 1 it bisects the horizon again. On
October 1 night arrives to stay until April 1.

At the equator, the sun is visible bisecting the southern horizon for
all 26 hours of the day on January 1. From January 1 to April 1, the
sun starts to dip below the horizon at night, to rise higher above it
during the day. During all this time it rises and sets at the same
hours, but rises in the southeast and sets in the southwest. At noon
it is higher each day in the southern sky until April 1, when it rises
due east, passes through the zenith and sets due west. From April 1 to
July 1, its noon position drops down to the north, until on July 1, it
is visible all day, bisected by the northern horizon.

3. CHEMISTRY AND GEOLOGY OF ULLER

Calcium and chlorine are rarer than on earth, sodium is somewhat
commoner. As a result of the shortage of calcium there is a higher
ration of silicates to carbonates than exists on earth. The water is
slightly alkaline and resembles a very dilute solution of sodium
silicate (water glass). It would have a pH of 8.5 and tastes slightly
soapy. Also, when it dries out it leaves a sticky, and then a glassy,
crackly film. Rocks look fairly earthlike, but the absence or scarcity
of anything like limestone is noticeable. Practically all the
sedimentary rocks are of the sandstone type.

All rivers are seasonal, running from the polar regions to the central
seas in the spring only, or until the polar cap is completely dried
out.

4. ANIMAL LIFE

As on Earth life arose in the primitive waters and with a carbon base,
but because of the abundance of silicone, there was a strong tendency
for the microscopic organisms to develop silicate exoskeletons, like
diatoms. The present invertebrate animal life of the planet is of this
type and is confined to the equatorial seas. They run from amoeba-like
objects to things like crayfish, with silicate skeletons. Later, some
species of them started taking silicone into their soft tissues, and
eventually their carbon-chain compounds were converted to silicone
type chains, from
