Oliver Onions,
Back o' the Moon, and Other Stories…
(1906)
“ The leagues of purple heather, that the weeks of continued heat had parched to a pale lilac hue, give place at this point to scarred and broken ground. Gorse and yellow bents spread north up the High Moor, and to the south, close to the road, lie the old coal workings. The bellpits, conical cavities ten or twelve feet deep, choked with ling and bracken, are scattered among innumerable hillocks of grey shale. That afternoon, over the hillocks farthest from the Causeway, where the heather began again, signs of recent disturbance were visible. ”
