Then two gray forms appeared from the east, diving at last into the gathering above, cavorting, playfully leaping and biting.

Finally one of the dolphins arched and dove straight down toward Toshio. "Hikahi's coming and wants the sssled topside," Keepiru chattered quickly, slurring the words almost into indecipherability. "Try not to get lost on the way up-p-p-p…

Toshio grimaced as he vented ballast. Keepiru didn't have to make his contempt so obvious. Even speaking Anglic normally, fins usually sounded as if they were giving the listener a long series of razzberries.

The sled rose in a cloud of tiny bubbles. When he reached the surface, water drained along the sides of the sled in long, gurgling rivulets. Toshio locked the throttle and rolled over to undo his faceplate.

The sudden silence was a relief. The whine of the sled, the pings of the sonar, and the squeaks of the fins all vanished. The fresh breeze swept past his damp, straight, black hair and cooled the hot feeling in his ears. It carried the scents of an alien planet — the pungence of secondary growth on an older island, the heavy, oily odor of a drill-tree in its peak of activity.

And overlying everything was the slight tang of metal.

It shouldn't harm them, they'd said back at the ship, least of all Toshio in his waterproof suit. Chelating would remove all of the heavy elements one might reasonably expect to absorb on a scouting trip… though no one knew for sure what other hazards this world might offer.

But if they were forced to stay for months? Years?

In that case the medical facilities of the Streaker would not be able to deal with the slow accumulation of metals. In time they would start to pray for the Jophur, or Thennanin, or Soro ships to come and take them away for interrogation or worse — simply to get off a beautiful planet that was slowly killing them.
