South 18th Street, which used to be the Brownsville Plank Road before it was taken into the city of Pittsburgh, snakes up through the South Side Slopes, following an ancient track that probably predates European settlement. It makes a long loop around a lumpy eminence known locally as Billy Buck Hill, where typical tall and narrow Slopes houses crowd on absurdly precipitous lots. These houses in the foreground are lined up along St. Paul Street. In the background, across the Mon, we see Oakland, which is as usual full of cranes.

The usual story of the etymology of Billy Buck Hill has to do with goats having been kept there, and that seems plausible. But old Pa Pitt is not willing to swear to it, because it has the look of one of those ex-post-facto etymologies suggested speculatively as the probable reason for the name, and then picked up as the only possible explanation and presented as fact.
