Bushka looked past them at the giant console with its graphic operational keys and large screens. One screen showed brilliant light on the ocean surface far above them. Another screen revealed the undersea tube where the Lighter-Than-Air hydrogen sonde was being prepared for its upward drift and launch into Pandora's turbulent atmosphere. A thin forest of kelp wavered in the background.

On Bushka's right, a triple thickness of plazglas also revealed the LTA launch base with Mermen swimming around it. Some of the swimmers wore prestubes for oxygen, all encased in their tight-fitting dive suits. Others carried across their backs the organic airfish that Islander bioengineering had pioneered for sustained work undersea.

We can produce it, but we cannot have the freedom of the undersea in which to use it.

Bushka could see where the leechmouth of an airfish attached itself to a nearby Merman's carotid artery. He imagined the thousands of cilia pumping fresh oxygen into the worker's bloodstream. Occasionally, a worker equipped with an airfish vented carbon dioxide in a stream of drifting bubbles from the corner of his mouth.

How does it feel to float freely in the sea, dependent on the symbiotic relationship with an airfish? It was a thought full of Islander resentments. Islander bioengineering surpassed that of the Mermen, but everything Islander genius produced was gobbled up in the terrible need for valuable exchange.

As I would like to be gobbled up. But there's not much hope of that!

Bushka suppressed feelings of jealousy. He could see his reflection in the plaz. The Committee on Vital Forms had faced no trouble in accepting him as human. He obviously fell somewhere near the Merman-tip of the spectrum. Still, his heavyset body, his small stature, the large head with its stringy dark brown hair, thick brows, wide nose, wide mouth, square chin - none of this came near the standard Gallow represented.
