Explore "The Swamp was Upside Down" by Murray Leinster on Textopian. Read with annotations and highlights.
Three hours after landing, Hardwick moved gingerly over grayish muddy / rock, with a four-thousand-foot sheer drop some twenty yards away. The / ragged edge of a cliff fell straight down for the better part of a / mile. Far below, the sea rippled gently. Hardwick saw a long, long line / of boats moving slowly out to sea. They towed something between them / which reached from boat to boat in exaggerated catenary curves. The / boats moved in line abreast straight out from the cliffs, towing this / floating, curved thing between them.
Hardwick regarded them for a moment and then inspected the grayish / mud underfoot. He lifted his eyes to the inland side of this peculiar / stretch of mountainside muddiness. There was a mast on the rock not far / away. It held up what looked like a vision-camera.
