The reports came in, excited yells from one end of the long, cluttered room to the other, exultant whoops and men pounding each other on the back. This was it! This was the treasure at the rainbow's end.

The substance and its properties were physically and chemically stable over a temperature range of hundreds of degrees. The breakdown voltage was up in the millions. The insulation resistance was better than the best known to Earth's science.

The dielectric constant could be varied at will by a simple electric field normal to the applied voltage gradient—a field which could be generated by a couple of dry cells if need be—and ranged from a hundred thousand to about three billion. For all practical purposes, here was the ultimate dielectric.

"We did it!" Friedrichs slapped Lancaster's back till it felt that the ribs must crack. "We have it!"

"Whooppee!" yelled Karen.

Suddenly they had joined hands and were dancing idiotically around the induction furnace. Lancaster clasped Rakkan's talons without caring that it was a Martian. They sang then, sang till heads appeared at the door and the glassware shivered.

Here we go 'round the mulberry bush, The mulberry bush, the mulberry bush—

It called for a celebration. The end of a Project meant no more than filing a last report and waiting for the next assignment, but they ran things differently out here. Somebody broke out a case of Venusian aguacaliente. Somebody else led the way to a storeroom, tossed its contents into the hall, and festooned it with used computer tape. Rakkan forgot his Martian dignity and fiddled for a square dance, with Isaacson doing the calling. The folk from the other end of the station swarmed in till the place overflowed. It was quite a party.
