Watch for snakes. Whistle loudly following the path towards Ball Hill Mine. The hum of blossom in remnant fruit trees along the Irish Town track.

Creeks and gullies and the Turon. Old maps in museums. Irregular outlines of geological strata and mining claims. Coaches shuttle primary school groups. Quiet nights with bright stars.
