Comprehensive straight-line hachure
rendering is discussed here because it forms the basis of the second approach which more closely resembles Lobeck's instructions.
While the mountain pictographs of the Homann map rely on an outline in combination with shade-lines on the southeastern slopes (implying high-oblique, northwest illumination), the mountain forms of the Dunn map are rendered by hachures
(slope lines) on multiple sides.
At a further remove there are the squalid block of flats, Flamingo Court down in Umbilo Road, where Halley's maternal Granny Margery lives, and also the area "back of the Berea Ridge, the maze of lanes behind Entabeni Hospital" (40) where her paternal grandmother Nana's much younger sister, Aunty Elda, and her husband Byron have a house, and where the narrative mapping more explicitly foregrounds the language of cartography: "Always, although she doesn't have the word, Halley pictures this space using hachures
, the contour lines on a map showing the steepness of a hill.
The mounds are rendered on the map as circles bordered by hachures
Even silhouettes and hydrologic ridge lines are sometimes drafted as a collection of short hachures
pointing in the direction of steepest slope.
The presentation of the maps harks back to the original printed maps of the period, with their distinctive watercolour-like tones, hachures
and lettering, and their fascinating historical and geological information.
