rain-line

Updated: May 1, 2025

Now, though there were thrushes and blackbirds about the brooks by London last winter, there were few in the hedges generally. Had they, then, flown westwards? It is my belief that they had. They had left the hard-bound ground about London for the softer and moister lands farther west. They had crossed the rain-line.
