Read it through once

The grainy sand had gone from under his feet. His boots trod again a damp crackling mast, razorshells, squeaking pebbles, that on the unnumbered pebbles beats, wood sieved by the shipworm, lost Armada. Unwholesome sandflats waited to suck his treading soles, breathing upward sewage breath, a pocket of seaweed smouldered in seafire under a midden of man’s ashes. He coasted them, walking warily. A porterbottle stood up, stogged to its waist, in the cakey sand dough. A sentinel: isle of dreadful thirst. Broken hoops on the shore; at the land a maze of dark cunning nets; farther away chalkscrawled backdoors and on the higher beach a dryingline with two crucified shirts. Ringsend: wigwams of brown steersmen and master mariners. Human shells.
