to ground and turned off.
That left the swarm at the door. The worker-robots under direct
control of the power-plant supervisors went after them, grappling them
and hauling them down to where Anse and Jerry Rivas and Captain
Nichols could turn them off manually.

The aircar was a hopeless wreck, but its radio was still functioning.
Conn called Charley Gatworth, who called a gang under Gomez, working
not far away; they came with another car.

It took all the next day for a gang of six of them to get the place
straightened up. Neither Conn nor Gomez, who was a roboticist himself,
would trust any of the workers or the two supervisors; their
experiences out of control had rendered them unreliable. They took out
their power units and left them to be torn down and repaired later.
Other robots were brought in to replace them. When they were through,
the power-unit cartridge plant was ready for operation.

Jerry Rivas wanted to start production immediately.

"We'll have to go back to Poictesme pretty soon," he said. "We don't
want to go back empty. Well, I know that no matter what we dug up, and
what we could sell or couldn't sell, there's always a market for
power-unit cartridges. Electric-light units, household-appliance
units, aircar and airboat units, any size at all. We run that plant at
full capacity for a few days and we can load the _Harriett Barne_
full, and I'll bet the whole cargo will be sold in a week after we get
in."

The _Harriet Barne_ settled comfortably at the dock, the
bunting-swathed tugs lifting away from her. They had the outside sound
pickups turned as low as possible, and still the noise was deafening.
The spaceport was jammed, people on the ground and contragravity
vehicles swarming above, with police cars vainly trying to keep them
in order. All the bands in Storisende seemed to have been combined;
they were blaring the "Planetary Hymn";

_Genji Gartner's body lies a-moldering in the tomb,
But his soul goes marching on!_

When they opened the airlock, there was a hastily improvised
ceremonial barge, actually a farm-scow completely draped in red and
white, the Planetary colors. They all stopped, briefly, as they came
out, to enjoy the novelty of outdoor air which could actually be
breathed. Conn saw his father in the scow, and beside him Sylvie
Jacquemont, trying, almost successfully, to keep from jumping up and
down in excitement. Morgan Gatworth to meet his son, and Lester Daw
