Wednesday 21 February 8.00 pm Invisible Photography Adrian Davies

Visible light is only part of the electromagnetic spectrum distinguished by what our eyes are sensitive to. However some organisms are sensitive to longer wavelengths (infra-red light) and/or shorter wavelengths (ultra-violet light). By photography in these regions we can see what birds and insects see.

The History of the Allotment Movement in England Judy Hill

In 1841 Thomas Martin founded the Reigate Cottage Gardeners Society which provided twelve allotments near Reigate. This was part of a movement that started mainly in the 19th century. By 1873 there were 243000 allotments, rising to 600000 by 1913 and peaking at 1.5 million during the First World War. In the Second World War it peaked at 1.75 million. A new peak arose during the Covid-19 pandemic. Judy will explain the origin with events such as the swing riots of the 18th century and its later history.
