So how is the beautiful little chalk stream,post 629? has the Water Board ruined it yet like the others, filling it with toxic sewerage and chemicals? The good news is the first Swallows arrived yesterday, having flown thousands of miles to get here. Alas, in the past years, their numbers have declined and declined, so no longer will they be skimming those Chalk Streams after Mayflies and other insects, and we will be the poorer for it.
