author
1884–1942
Best known for an early practical guide to keeping flocks healthy, this little-known writer focused on useful, hands-on subjects rather than literary fame. Surviving records also link the author to a much earlier book on Jamaican souvenir crafts, hinting at an unusually varied career.

by E. J. (E. Jocelyn) Wortley
E. J. (E. Jocelyn) Wortley, born in 1884 and died in 1942, is chiefly remembered today for Poultry Diseases: Causes, Symptoms and Treatment, with Notes on Post-Mortem Examinations, published in 1915. The book was presented as a practical manual for poultry keepers, and surviving editions credit Wortley as F.C.S., suggesting a scientific or technical background.
Library and archive records also connect Wortley to Souvenirs of Jamaica from 1906, a book about the making of local curiosities and souvenirs. Taken together, these works suggest an author interested in clear, useful information for readers in everyday trades and industries.
Very little biographical detail seems easy to confirm beyond the basic dates and publications, so Wortley remains a somewhat shadowy figure. Even so, the books have lasted because they are direct, specific, and rooted in practical knowledge rather than theory.
