rooftop, humming, edge

The movement of pigeons' feet is usually entertaining if watched carefully.

Three cyclists, one after the other, free wheel down Mount Sion, their bicycles humming on a continuous note like insects.

Tidiness and wildness do not, as a rule, go together in a garden. It seems to me that part of the art of gardening is to contain the one within the other. I reflect on this as, not entirely characteristically, I make a neat edge between an area of brickwork and the newly cut grass, and step back to admire the effect - too much like a public park or formal garden, I think to myself, but feel a sense of satisfaction nevertheless.
