author

by E. J. (E. Jocelyn) Wortley
Published as E. J. (E. Jocelyn) Wortley (1884–1942), this writer is credited with works including Poultry Diseases: Causes, Symptoms and Treatment (1915), a practical guide for poultry keepers that focuses on prevention, symptoms, treatment, and post-mortem notes.
Another documented book, A Companion to Blackie's Tropical Readers, Books I and II (1911), presents classroom experiments and practical work for teachers. Its introductory material praises Wortley’s experience in teaching elementary school teachers, which suggests a background in science education as well as agricultural writing.
Only limited biographical information was easy to confirm from reliable online sources, so much of Wortley’s life remains obscure. Even so, the books that survive show a writer interested in useful knowledge, plain explanation, and the everyday application of science.
