London. December 1919. A notable gathering recently witnessed the initial screening of the first series of educational films produced by British Instructional Films, Ltd. The audience included Members of Parliament, Members of the London County Council, Local Government and Educational Authorities, well-known professors of Science, Natural History, Astronomy, and, in fact, every note in the educational world. The programme of films screened comprised six very entertaining educationals, one of which was “The Evolution of a Caddis Fly.”

This interesting subject depicts the life history of this handsome fly, which lives a good portion of its existence under the water – the photography was remarkably sharp, and the treatment of the subject gave striking testimony of being the work of a master mind.
