Gesturing him back, Bukal swung the disc clear of the ground, holding it waist-high, plate-flat. "Now, I spin it...." He whipped it round as if its center were mounted on a pivot, pulling through with his right hand, guiding with the left.

The boat was almost to the island now. The guards were readying their weapons.

Faster, till the wave-flow catches.... The disc was spinning like a top now, parallel with the ground.

Craig threw a quick glance at the guard-boat. A trickle of sweat rilled down his spine.

He looked back to Bukal and the saucer.

Suddenly, there was the slightest of jerks. The disc seemed to vibrate.

Bukal dropped his hands. For a moment the disc hung in the air, spinning free.

And then, incredibly, instead of falling, slowly it began to rise!

Open-mouthed, Craig stared, still not quite believing.

But already, Bukal, was moving. Nimbly, he threw himself forward, flat on the disc.
