There were a few dots of lights. Then we passed the first group of houses. Very queer. Nereid stared at me. Queer indeed. It was far into the time of sleep, but still there should have been someone attracted to the house doorways as we passed.
We had slackened now, with the houses, most of them dark, clustering all about us.
"There is Venta's home," Nereid murmured. "Her father and brother will be there."
We drifted under an arching bridge. The figure of a man was lying on it. Asleep? Nereid called softly to him, but he did not move. Then I was aware of a queer, acrid smell here. Choking smell. Nereid coughed suddenly.
The boat landed at a low platform dock of Venta's home. We jumped to the platform. Two men were here. Venta's father and brother. They lay in a heap, one half upon the other. Dead! The opalescent sheen of the glorious night was ghastly on their dead faces; mouths goggling with blackened, protruding tongue; eyes staring with the agony and death.
And from here we could see other house balconies. Inert forms on them. All dead.
In that stricken second, as we stood shuddering on the little platform with the sea lapping under it, a new horror suddenly assailed us. There was a tangle of vegetation here, tree branches overhead; air-vines with redolent flowers and pods on them, dangled, swaying in the breeze. And abruptly I realized that the dangling, rope-like vines were visibly growing! At an edge of the platform one of them was slithering like a serpent!
And Nereid gasped: "That smell! The gas of nitro-carbon in some terrible concentration!"
I stood numbed. Nitrogenous gas-fumes, sprayed here on the night-breeze by what deadly means I could not guess, had asphixiated the people of the little Water City. Most of them asleep, they were quickly overcome by the insidious fumes. An intensification of the gas which was normally used by the Arones to stimulate vegetation growth, as we on Earth use fertilizer. Nitro-carbon—deadly to humans; stimulating to plant-life!
And the air-vines here were growing with a deadly acceleration!
