E.H.T. Bible's natural history diaries, recording sightings of birds, mammals, sea creatures, insects and plants, mainly in and around Aberdyfi, Wales, with notes on location, species, identification, habits, migration patterns and weather conditions. Names of species are often underlined in red ink. Instances of dead animals, egg collecting, fur dealing, trapping and shooting are recorded, and the need for protection acknowledged. The observations of others are frequently noted, including Dr J.H. Salter and Miall Jones, both of Aberystwyth, Wales, and Mary Richards of Dolgellau, Wales. There are touches of humour in Bible's descriptions of encounters with animals and people. Gardening activities are noted in the later diaries, and, from 1943, rainfall records are kept. Most of the diaries are labelled 'Fair Copy', but the series includes two small notebooks containing draft versions.
