As for the muses, they have as much of an idea of a rhinoceros as of a poet.

Some pre-departure research:

• Possible explanation for the placing of a rhinoceros on top of a bus stop in Dumfries, as suggested by my father.
• Actual explanation of the placing of a rhinoceros, (not actually on top of the bus stop, as it turns out, but nearby,) in Dumfries, as suggested by Google.
