r ramps, the
Phoenix can't stay around long enough to burn through them, because the
Masters have probably already called for help from Mars City."

Maya had laid her marshelmet down on one of the bunks, and was pulling
the marsuit on over her tunic and trousers.

The door at the other end of the room opened, and a man emerged, a
heatgun in his hand.

Vidonati stopped in his tracks, startled, at the sight of Dark and Maya.
Dark grunted in surprise, and reached for his heatgun.

Even as Dark freed his weapon, Vidonati fired. The beam missed them,
melting away the top of Maya's marshelmet and setting the bunk aflame.
Then, as the beam of Dark's gun swung toward him, Vidonati ducked
precipitately back into the control room.

"He got your marshelmet!" exclaimed Dark. "We're going to have to go in
and flush him out of there, and just hope there's another marsuit in
there, before we can open the airlock."

Heatgun in hand, Dark started for the door of the control room, Maya at
his heels.

It was then that the Phoenix, the three groundcars drawn up with their
heavy guns focused, blasted the airlock of the north building. In
seconds, the airlock was burned through.

There was no emergency barrier down on this ramp. The heavy,
Earth-pressured air of the north building whistled out into the desert.
As from a punctured balloon, the pressured atmosphere of the entire
Canfell Hydroponic Farm rushed after it, roaring up the ramp, in a
moment stripping the vats, the upper level and the north building.

Caught in the tornadic blast, Dark could only cling to a bolted-down cot
with one hand, and hold onto Maya around the waist with the other. As
the pressure dropped precipitately and oxygen no longer touched his
lungs, he could actually feel his alternate metabolism shifting into
gear, he could feel his breathing stop and the glow of solar energy
begin to spread through his body.

As the wind faded and died, Dark released Maya and rose exultantly to
his feet. Down below, he knew, Nuwell and the Masters were gasping out
their lives in the thin air, like beached fish. Their recent attacker,
Vidonati, lay half out of the door of the control room, his hands
clutching convulsively at the floor.

"That's not the way I'd planned it, but it's just as good!" Dark
exclaimed. "We've taken the farm!"

Then he remembered. Maya had no marshelmet!

Appalled, struck to the heart, he turned in his tracks.

Maya was standing behind him,
