By motions and words we didn't understand, we inferred that we were invited to accompany the party back home, inside the hill, where we would be safe. I nodded to Campbell. "It's our chance to be guests of Tomboldo." Nothing could have pleased us more. For our big purpose—to understand the Serpent River—would be forwarded greatly if we could learn, through the people, what its meanings were. To analyze the river's substance, estimate its rate, its weight, its temperature, and to map its course—these facts were only a part of the information we sought. The fuller story would be to learn how the inhabitants of this planet regarded it: whether they loved or shunned it, and what legends they may have woven around it. All this knowledge would be useful when future expeditions of men from the Earth followed us (through EGGWE) for an extension of peaceful trade relationships.
Tomboldo depended upon the guard Gravgak to make sure that the way was safe. Gravgak was supposed to keep an eye on the line of floating trees that had taken flight down the hillside. Danger still lurked there, we knew. And now the siren that had frightened off the attack was silent. Our ship, locked against invaders, could be forgotten. We were guests of Tomboldo.
Gravgak was our guard, but he didn't work at it. He was too anxious to hear all the talk. In the excitement of our meeting, everyone ignored the growing darkness, the lurking dangers. Gravgak confronted us with agitated jabbering:
"Wollo—yeeta—vo—vandartch—vandartch! Grr—see—o—see—o—see—o!"
"See—o—see—o—see—o," one of the others echoed.
It began to make sense. They wanted us to repeat the siren noises. The enemy had threatened their lives. There could very well have been a wholesale slaughter. But as long as we could make the "see—o—see—o" we were all safe.
Split and I exchanged glances. He touched his hand to the equipment jacket, to remind me we were armed with something more miraculous than a yowling siren.
"See—o—see—o—see—o!" Others of Tomboldo's party echoed the demand. They must have seen the sponge-trees again moving toward our path. "See—o—see—o!"
Our peaceful march turned into a spasm of terror. The sponge-trees came rushing up the slope, as if borne by a sudden gust of wind. They bounced over our path, and the war party spilled out of them.
Shouting. A wild swinging of clubs. And no cat-and-mouse tricks. No deliberate circling and closing in. An outright attack. Naked bodies gleaming in the semi-darkness. Arms swinging weapons, choosing the nearest victims. The luminous rocks on the ends of the clubs flashed. Shouting, screeching, hurling their clubs. The whizzing fury filled the air.
