The day the earth-moving machines arrived, it was as if aliens had invaded Earth. Overnight they appeared, diggers with huge scoops, plodding their slow and ancient ways across the landscape. By the next week they had multiplied and evolved into diverse forms—cranes with long arms, bulldozers and levellers, an assortment of lorries. All day they worked towards some unseen design, creating and removing debris, their latticework of tracks remaking and writing over the space. Untenanted and vulnerable, the attap huts offered no resistance.
