planet.
Two of the continents were on the equatorial line. Their interiors were
masses of firestorms so bright that they could be seen through the clouds.
Here and there were darker areas which the scientists said were the results
of heavy rains. The fires had been put out there, but the bordering regions
were so hot that the moisture would quickly be dried up and the vegetation
reignited.
"There were vast rain forests there," Toyce said. "Much like those in
Africa and southeast Asia before they were cleared and became deserts."
Ramstan decided to investigate at close range one of the continents in the
southern hemisphere. It had a great interior desert but had been heavily
populated on the coastlines. Though the fires were still raging along
the shores, extending sometimes to 300 kilometers into the interior,
there were temporarily extinguished areas. The clouds had moved in from
outlying areas, carried by the very strong winds, but spacesuited personnel
could fly in jeeps a few meters above the still-quaking ground.
Al-Buraq poised above an area where rain was falling heavily. The stony
desert was only 10 kilometers to the north, but ruins of buildings
indicated that the region directly beneath ship had once been thickly
populated. Not that there were many objects detectible by the probers.
Most of the wooden materials and trees and bushes had been burned
entirely and their ashes swept away by the winds and rains. If there
were any bones left of the sentient and animal inhabitants, they could
not be detected by the probers.
The chief meteorologist reported again.
"The winds have a velocity of 150 kilometers per hour. They're mild,
though, compared to the winds in the northern area."
Ramstan knew this because he could read the indicators on the tec-op
panels. He thanked the scientist, anyway. What interested him was the
detection by the fine-discriminator probers of thousands of golfball-shaped
and -sized objects on the ground or half-buried in the mud. He ordered
that the investigators in the jeeps secure some of these. Then, impatient,
he commanded al-Buraq to get close enough to the surface to extend a
suction pseudopod and bring in some specimens immediately.
While waiting, he ordered a launch sent to the northern shoreline to
determine if there were similar objects there. "And if you find them,
proceed to the continent above this in the northern hemisphere and look
for them there."
Al-Buraq headed into the wind at 5 kph. It was not easy for her to scoop
in the spheres. The ground was subject to shock after shock, many strong
enough to toss the spheres a meter into the air. A few times, fissures
opened, and the spheres fell into them. Al-Buraq did not try to obtain
these. If she had inserted her pseudopod into the fissure, she might
have been trapped if the fissure closed.
At another order, ship brought in some pieces of what had been stone
columns and some twisted and dented steel beams.
The chemicophysical laboratory reported that there were many smaller spheres
in the mud which had been carried in. These had a diameter of three
millimeters.
Al-Buraq continued sampling, and she began to trace a spiral path over
a twenty-square-kilometer area.
The launch left ship with two pilots and six scientists aboard. It shot
northward at 300 kph, its probers scanning the area for 100 kilometers
on both sides.
The laboratory chief reported again.
"The larger spheres have a diameter of four centimeters. Each weighs one
kilogram. Each has a shell of nickel-iron five millimeters thick. That's
estimated, since the shell has been partially melted and some of the
nickel-iron has evaporated. Burned off. The core is some black, unknown
substance, though it looks like metal. It can't be X-rayed. It's unaffected
by the strongest acid. It won't bend or break under a pressure of
