16 June 1939, a large number of tiny frogs fell on the village of Trowbridge in Wiltshire. According to the Meteorological Magazine:
Mr E. Ettles, superintendent of the municipal swimming pool, stated that about 4.30 p.m. he was caught in a heavy shower of rain and, while hurrying to shelter, heard behind him a sound as of the falling of lumps of mud. Turning, he was amazed to see hundreds of tiny frogs falling on to the concrete path around the bath. Later, many more were found to have fallen on the grass nearby.
This book offers an explanation.
The mainly chalk grasslands of the Marlborough Downs are home to an interesting experiment in a farmer controlled biodiversity scheme.
Stephen Moss writes in Wild Kingdom
….as the people on the Marlborough Downs like to point out, their scheme has only worked because the impetus came from the bottom up. Because all the farmers here bought into the project, and put in so much of their time to make it succeed, they feel a real sense of ownership. This personal connection means that in the longer term, when the government money runs out, wildlife-friendly farming will continue to thrive here. And the scheme has had other, unexpected benefits: allowing people to get to know their neighbours, creating a more cohesive sense of community, and putting the Marlborough Downs firmly on the map.
