Starborne (38 page)

They are close enough to the ground now to see, even through the driving rain, that their guesses from on high were correct, that this planet is completely engulfed by an enormous webwork of gigantic woody vines, seemingly endless vines whose tr
unks have a diameter of at least ten meters and probably more, vines like horizontal trees that crisscross and overlap and entangle, leaving no free spaces between them an
y
where.

Sonar shows the underground tunnels they had noticed from above, weaving thro
ugh the vines beginning at a depth of perhaps forty meters and running both laterally and downward, in some places descending for a kilometer or more. Below the tunnel zone lies something that appears to be one great solid spongy mass, hundreds of kilomet
e
rs thick, out of which all the vines seem to be sprouting. It is the mother-substance, a
p
parently, the living substructure of the entire giant organism
—
for it is rapidly becoming clear to them, now, that Planet B is
occupied by one immense vegetable entity, which is this spongy subterranean mass, from which all else springs. And beneath that is the stone understructure of the planet, the hidden basalt core.

Where to land? There are no open places, no meadows, no plain
s.

Huw expends a little reaction mass to create one, tipping the probe up on end and flaming the upper edges of a few vines until there is a sati
s
factorily flat landing-zone below them. There is no reaction from the vines adjacent. They do not writhe, nor
do they even stir; they give no indication of any sort that Huw
’
s assault on this very small sector of the planetary flora has caused the slightest resentment, let alone set in m
o
tion some kind of retaliatory action.

He sets the probe down nicely. Waits a
moment for it to finish roc
k
ing. The landing-zone he has improvised is a little on the uneven side.

“
Tests, now,”
Huw tells the year-captain, unnecessarily.

They run through all the prescribed extravehicular testing routines, checking this thing and that,
the acid content of the rain and the poss
i
bility of atmospheric toxins and such. Not that they have any intention of exposing themselves to direct unshielded intake of the atmosphere out there, not on an alien world that they are already almost certain wil
l be of no avail as a place where human beings might settle happily. But they are aware that extraterrestrial chemistries might provide nasty surprises even for explorers protected by spacesuits. So they take the proper pr
e
cautions.

The rain is unrelenting
. It works the skin of the little spaceship over like a trillion tiny hammers.

“
At this point on the last planet,”
Huw says, “
I was already beginning to feel strange. The queasies had started to strike before I was even out of the probe.”

“
And now?”

“
Nothi
ng. You?”

“
Nothing at all.”

“
But let
’
s see how it goes for us when we
’
re outside, shall we?”

A little comedy surrounds their going outside the ship. The year-captain, having previously made it clear that he looks upon Huw as the leader of the party, indica
tes with a nod that he will defer to Huw in the matter of being the first to set foot on this planet. But Huw, who has been the first to set foot on one extrasolar planet already, is quite willing to let the year-captain have the honor on this one, and de
f
ers right back to him. Of course, there is the possibility that the first one outside the ship will be the recipient of some sort of disagreeable jolt, but each man, in his deference to the other, goes to some length to make it clear that such fear is def
i
nitely not an item in his considerations, not at all. Cou
r
tesy is the only issue.

“
Go
on
,”
the year-captain says irritably, in the end.

“
Well, then. Yes, if so you say.”

Huw shimmies through the hatch and cautiously steps down onto the charred, still faint
ly sizzling surface of the landing area that he has fas
h
ioned. There is a slight resilience, a little give, beneath his weight. He can detect no untoward psychological effects.

“
Everything all right so far,”
he announces.

The year-captain joins him. Togeth
er they walk toward the edge of the clearing; and then, after just a moment of hesitation, they step out together onto the upper surface of one of the unburned vines.

It is an unappealing surface. Big scrofulous leaves, blue-black and stemless, pocked with
ugly blister-shaped air-bladders sprout directly from the wood at sparse intervals. Dull red streamers hang from their edges like bursts of entrails. In the bare places between the leaves the trunks of the vine have a disagreeably gluey texture.

“
Well?”
H
uw asks.

“
A little sticky, isn
’
t it?”

“
I mean your mind.”

“
Still functioning, thank you. And yours?”

“
I was ready to scream, by this point on Planet A. Already
was
screaming a little, as a matter of fact. Things are different here, it seems. So much for Gi
ovanna
’
s theory, let
’
s hope.”

“
Vile place even so, isn
’
t it?”
the year-captain says.

“
Utterly repugnant. Absolute trumps, as repugnant goes. Shall we move a little further onward, old brother?”

It is almost like being under water. By their calculations it
’
s the midday hour, with a medium-sized sun hovering right above them just a few dozens of millions of kilometers away, and yet they are shrouded in a deep twilight gloom. There is one place in the sky where a somewhat lighter blurry patch stands out again
s
t the thick gray mantle of clouds: that
’
s the sun lurking back there, no doubt. The rain, falling as it does in dense sheets, is dispiriting in the extreme. It must not have stopped raining here in millions of years. The water hits the corrugated woody su
r
faces of the huge vines and goes slithering off into the narrow cre
v
ices between them. Perhaps some of it trickles downward from the pla
n
etary surface for hundreds of kilometers until it comes to rest in pockets of unimaginable darkness along the flat face
of the rocky core; but most of the deluge simply bounces right back up in instant evaporation. All about them they can see heavy clouds of vapor climbing stubbornly through the furious vertical scything of the downpour.

The vines themselves form a vir
tually impenetrable covering. They lie side by side like the threads in some colossal tapestry, occasionally overlapping, each one stretching on and on for what may well be kil
o
meters; there is not so much as a fingersbreadth of room between each one and i
ts neighbor. Their greenish-purplish bark is sturdy and yet rubbery, yielding a little beneath the feet of the two explorers. It bears not just leaves but pulpy fungoid masses that sprout in random patches all over it, and also scabrous gray coatings of t
h
e local equivalent of l
i
chen. These are soft as cheese, these parasites or saprophytes or symb
i
otes, whatever the case may be, creating a treacherously slippery su
r
face, but it is difficult to avoid walking on them. Between these various excrescent outgrow
ths it is possible to see numerous large oval bodies, greenish in color and smooth in texture, set in the bark of the vines four or five meters apart from one another like a host of unblinking eyes: they appear to have a significant function for the vines,
perhaps suppl
e
mentary instruments that aid the strange leaves in conducting some kind of photosynthetic process in this dismal subaqueous light.

Everything here seems to be rotting, decaying, decomposing, and r
e
constituting itself all in the same process.
This world would have made a good penal colony, maybe, in the fine old days when cruel and unusual punishment was a popular human pastime. But it doesn
’
t seem good for very much else.

“
Have we seen enough, do you think?”
Huw says.

The year-captain points
straight ahead. There is a round dark place up there, like the mouth of a cave, set between two vine-trunks. The e
n
trance, it seems, to one of those long underground tunnels that had shown up on the sonar images. “
Shall we take a look inside?”
he asks.

“
Ah
. You want to go in there.”

“
I want to go in there, yes,”
says the year-captain in a quiet tone.

“
Well, then, why not?”
says Huw, not very enthusiastically. “
Why not, indeed?”

The year-captain leads the way, without discussion of issues of pre
c
edence. The
tunnel is wide and low-roofed, ten or twelve meters broad but scarcely higher than the tops of their heads in some places. It runs at a gently sloping downward angle right through the corpus of the vines, slicing casually from one to the next; its walls,
w
hich are the substance of the vines, are moist and pink, like intestines, and a kind of sickly phosphorescent illumination comes from them, a feeble glow that breaks the dense darkness but is of little help to vision. Huw and the year-captain activate the
i
r helmet lamps and step a little farther within, and then a little farther yet.

Huw says, “
I wonder what could have constructed these
—”

“
Hush,”
says the year-captain, pointing ahead once again. “
Look.”

He walks forward another dozen meters or so and steps
up the inte
n
sity of his beam. The tunnel appears to be blocked, up ahead, by a plug of some sort; but as they get closer to the blockage they can see that the “
plug”
is slowly retreating from them
—
that it is, in fact, some enormous sluggish elongated flat-
topped creature which not only is moving in worm-like fashion along the floor of the tunnel but is evidently
creating
the tunnel, or at least expanding it, by devouring the fabric of the vine through which the tunnel runs.

“
Fabulous,”
Huw murmurs. “
What do
you know, we
’
ve found extr
a
terrestrial animal life at last, old brother! And what a beauty it is!”

There is no way for them to tell how long the tunnel-worm is. Its front end is lost in the darkness far down the way. But they are able to see that its body
is three times the width of a man
’
s, and rises nearly to their height. Its flesh is translucent and pink in color, a deeper pink than that of the tunnel itself, more in the direction of scarlet, and has a soft, buttery look about it. Black hairy fist-siz
e
d pores are set low along the creature
’
s sides, every fifty centimeters or thereabouts, going forward on it as far as they can see. From these orifices comes a steady trickle of thin whitish slime that runs down the curving sides of the thing and lies pud
d
led in rivulets and pools along the tunnel floor around it. An excr
e
tion product, no doubt. The worm seems to be nothing more than an eating-machine, mindless, implacable. It is steadily munching its way through the vine and turning what it eats into a str
eam of slime.

Indeed they can hear the sounds of feeding coming from the other end of the creature: a snuffling noise and a harsh chomping noise, both above a constant sixty-cycle drone. All these sounds, which seem to be related, go on without letup. An e
ating-machine, yes.

The two men creep a little nearer, taking care not to let their boots come in contact with the deposits of slime that the great worm has left in their path. When they are as close to the creature as they dare to get, it becomes possible
for them to perceive curious glowing cyst-like stru
c
tures, dark and round and solid and about the size of a man
’
s head, di
s
tributed with seeming randomness within the flesh of the thing, scattered here and there at depths of a third of a meter or more. Th
ese cysts make their presence known by a bright gleam like yellow fire that emanates from them and rises up through the flesh of the worm to its pink puc
k
ered skin.
